abstract
Sustainable development is prompting a re-assessment of innovation and technological change. This
review paper contributes three things towards this re-assessment activity. First, it considers how the
history of innovation studies for sustainable development can be explained as a process of linking
broader analytical frameworks to successively larger problem framings. Second it introduces an emerg-
ing framework whose allure rests in its ability to capture the bigger picture: the multi-level perspective
on socio-technical transitions (MLP). Whilst burgeoning researcher networks and literature suggests this
policy-relevant theory is attractive, it is not without its challenges. The third purpose of this paper is to
elaborate these challenges as areas for further research and development. We do this by drawing upon
contributions to this special section and the wider literature.

1. Introduction
The promise of greener innovation has long featured in debates
about mitigating environmental degradation under industrial
development. Emphasis in innovative capabilities lay at the heart
of critical responses to the Malthusian Limits to Growth report by
the Club of Rome in the 1970s (Meadows, 1972). Critics argued that
the Club’s modelling underplayed the possibility for innovation to
stretch and redefine ‘limits’, and thereby avoid environmental and
social collapse (Cole et al., 1973; Freeman, 1979). More recently,
ideas about ecological modernisation consider how innovation can
redirect production towards environmental goals, and decouple
economic growth from environmental degradation (Jänicke, 1985,
1988; Huber, 1982, 1993; Spaargaren and Mol, 1992; Vergragt and
Jansen, 1993; Hajer, 1995).
Innovation studies has much to offer those interested in
ensuring new products, processes and services improve human
wellbeing without detriment to environmental life support sys-
tems. Innovation studies can explain how and why such “greener”
production and consumption practices come about, or do not, and
suggest how these kinds of practice might be accelerated at the
expense of environmentally more harmful alternatives. We note
that concern for sustainable development tends to demand a broad-
ening of perspective in innovation studies. The first purpose of this
paper is to explain the logic for this broadening of perspective. It
works on two dimensions.
The first dimension is a broadening of the problem framing. This
comprises definition of the purpose and outcomes of innovative
activity and, linked to this, delineation of the focal object of inno-
vation studies, i.e. the “thing” that undergoes innovation. Thus we
explain a broadening from a focus on the promotion of cleaner
technologies in the 1980s and towards current interest in inno-
vating entire systems of production and consumption. The second
dimension is a broadening of the analytical framing: the set of consid-
erations used to explain the emergence and success of innovation.
This starts from a neo-classical environmental economics under-
standing of price signals inducing innovation and leads into a
variety of innovation systems perspectives.
We argue that developments in both dimensions, problem
framing and analytical approach, have done a lot to increase the
significance of innovation studies for sustainable development.
Nevertheless, a further step is under way. A broad, multi-level
perspective on socio-technical transitions (MLP) claims to be able
to analyse the broader problem framing of innovating entire sys-
tems of production and consumption. The introduction and critical
assessment of the MLP is the second purpose of this paper.
The MLP developed out of explanations for historic transitions
to new socio-technical systems for mobility, sanitation, entertain-
ment, food, lighting and so on. Successful systems are constituted
from networks of artefacts, actors, and institutions and gain sta-
bility and path-dependence as particular ‘socio-technical regimes’
(e.g. the regime of centralised power generation on the basis of fos-
sil and nuclear fuels). The conceptual understanding of transitions
to new regimes draws upon theories at the interface of innovation
studies and STS. They combine a view on the micro-level processes
of constructing new technologies, with a view on emerging macro-
and meso-level patterns of culture, organisation, markets, regula-
tion and infrastructures (Rip and Kemp, 1998; Schot, 1998; Geels,
2002).
The allure of the MLP for sustainability research rests in
this engagement with the dynamics of large-scale socio-technical
systems deemed to present persistent sustainability challenges
(Rotmans et al., 2001; Berkhout, 2000; Elzen et al., 2004). How-
ever, this attractive big picture is not without its challenges. A third
and final purpose for our paper is to draw on contributions to this
special section in order to discuss some of the challenges1: concep-
tual challenges in terms of defining the unit of analysis; analytical
challenges in addressing structural power, agency, and geography;
and practical challenges in appraising the governability of socio-
technical transitions. We conclude by suggesting what this means
for future research agendas in this area.
The contributions to this special section force reflection on nor-
mative orientations in innovation processes and the social and
political aspects of knowledge production and technology develop-
ment. This may inspire further development of innovation studies,
connecting innovation theory with science and technology stud-
ies (STS). As Frank Geels’ contribution points out, explicit concern
for normative directions can further open innovation studies to
theoretical and ontological traditions that have hitherto remained
marginal. A recent review of STI called for precisely that kind of
broader dialogue between approaches, as well as being more reflex-
ive in the analysis of innovation (Morlacchi and Martin, 2009). The
contributions in this special section are in that spirit, and suggest
the MLP provides a promising heuristic for organising such a dia-
logue. Our intent is not to present the MLP as a finished product, but
to introduce it in a critical and reflexive way that invites others in
innovation studies to contribute to its future development. Whilst
the future research agenda we identify includes issues pertinent
to the MLP as an analytical framework, we also flag up issues that
relate to the practical challenge of governing sustainable transitions
in general.
In following the aims for this paper we cover considerable
ground. The next section explains the broadening of problem fram-
ings and analytical approaches. Section 3then introduces the MLP.
The state of the art for the MLP shows its breadth and work in
progress quality and gives a background to its use as a flexi-
ble heuristic. This is reflected in the diversity of the contributing
papers. Section 4summarises main points from these contribu-
tions, before Section 5discusses the challenges they raise for the
MLP and sustainability transitions. Section 6concludes with sug-
gestions for a future research agenda.
1Each of the contributors to this special section participated in a workshop we
organised in Berlin in September 2007 on The Politics and Governance of Sustain-
able Transitions, and which was funded by the German Ministry for Research and
Education under its programme for Social-Ecological Research and the Dutch KSI
Programme. Participants were invited to engage with the MLP and to identify and
explore critical issues of particular relevance to their research. The papers in this
special section seem to us to present especially pertinent and challenging issues for
the MLP and policy-relevant theory for sustainability transitions generally.

2. The logic of adopting a broader perspective in
sustainable innovation
Sustainable development emphasises explicit interest in the nor-
mative direction of innovation. The challenge for innovation no
longer rests solely in economic potential, but also in the societal
changes induced by innovative activity and the consequences of
this for environmental and social sustainability. Along with this
broader problem framing, comes a need for broader analytical per-
spectives.
Innovation system analysis is an approach that has been help-
ful in explaining the level of innovative activity: the quantitative
output from economies, sectors or regions in terms of new patents,
products or technologies. Adapted to particular technologies it has
also helped to understand the success and failure of certain inno-
vations and related economic sectors in different economies. This
builds on an analytical framing which includes public policies,
institutional settings, inter-organisational networking, learning
processes and knowledge infrastructures, and entrepreneurial
capabilities. Innovation systems can help us understand how
the flow of greener goods and services might be accelerated,
but appears not so clear in understanding how these rely upon
and induce broader structural changes for sustainable develop-
ment.
The challenge of sustainable development demands policies to
promote a change in what Hughes (1987, pp. 15–16) has called
the momentum of socio-technical systems. This comprises mass
(the objects, actors and infrastructures involved), speed (the pace
at which socio-technical developments and their alignment devel-
ops), and direction (the overall performance of the system changes
as a result of innovations). The direction of momentum is probaly
the most challenging one, helping innovative activity move onto
a path where desired outcomes can be expected, and deflecting it
from less desirable trajectories.2
Directionality is not only challenging for reasons of the uncertain
systemic effects of innovations. It is also challenged by ambivalence
over standard measures of ‘sustainability’. The precise mean-
ings and trade-offs for society between specific environmental,
social and economic features of innovative activities are open
to interpretation and negotiation. Sociological sensitivity towards
inter-subjective meanings of sustainable innovation, and the role
of political and economic power in privileging certain perspectives
over others, becomes important. Sustainable development may
thus be seen as broadening innovation studies to include reflexivity
issues more typical in STS, but turned towards innovation studies
concerns for the large-scale creation of novelty, industry structure
and evolutionary change over the longer-term.
2.1. An initial broadening in problem framing: from clean
technology to industrial ecology
A theme prevalent in research and policy in the literature in
the early 1990s was interest in promoting innovation for envi-
ronmentally friendly technology. A switch in focus from early
preoccupation with end-of-pipe pollution control technologies and
towards cleaner production processes and product innovation rep-
resented an initial broadening in problem framing. The new cleaner
technology paradigm was concerned with innovations integral to
2The innovations systems perspective did develop out of consideration for
how innovation explained the contrasting structures and dynamics of national
economies. This can involve normative interest in the different directions of eco-
nomic development and the distribution of standard measures of prosperity. Here
we mean directionality in a more multivalent and contested normative concern
for sustainable development. Sustainability is not unique in rendering more visible
normative contests over innovation directions.
processes and products, reducing contamination, waste and mate-
rial use at source. Some argued the associated material savings
translated into reduced costs, and hence greater business com-
petitiveness (Ashford et al., 1985; Porter and van der Linde, 1995;
Howes et al., 1997; Rennings, 2000). Other studies foresaw new
environmental industries and new markets and jobs as the econ-
omy undergoes an ecological modernisation (Jänicke, 1988). This
remains a topic of considerable debate (York and Rosa, 2003).
Nevertheless, a dynamic and innovation-oriented consideration of
potential benefits for business provides a more positive outlook
and constructive ground for dialogue compared to static economy-
versus-environment debates.
Throughout the 1990s, some trade associations and firms
began innovating environmental management systems as a way of
demonstrating improving environmental performance to increas-
ingly attentive stakeholders (Welford, 1995).3The challenge was to
ensure that these environmental management approaches moved
from being a peripheral site-management exercise to become an
influence upon core business strategies and innovation agendas
across sectors (i.e. from concern for emissions from production pro-
cesses to concern for the life cycle environmental performance of
the goods and services produced). A literature in industrial ecol-
ogy broadened the problem framing further by considering how
either entire sectors or industrial parks might close loops and make
material flows more sustainable (e.g. Ayres and Simmonis, 1994).
The environmental innovation problem framing was broadening,
in the sense that it included organisational innovations across sec-
tors and the development of greener goods and services across the
lifecycle, and not just cleaner technology at the firm level.
2.2. Broadening the analytical perspective: from environmental
economics to evolutionary perspectives on environmental
innovation
Innovation studies rooted in evolutionary economics provide
a helpful corrective to (neo-classical) environmental economics
perspectives. The latter see the challenge of environmental innova-
tion as resting predominantly in adjusting price signals for goods
and services. Environmental considerations are poorly served by
existing markets, so the environmental economists argue, because
costs and prices fail to internalise environmental externalities, and
consequently fail to generate effective demand for cleaner inno-
vations (Pearce et al., 1989). Market-based environmental policy
measures (e.g. eco-taxes and tradable quotas) can internalise the
social costs of environmental degradation (i.e. market external-
ities), and thereby provide a more balanced price incentive for
innovating goods and services.4
Reliance on this ‘demand-pull’ approach has its shortcomings.
It brackets out many of the reasons why responses to environmen-
tal price signals are sticky and inelastic. Taxes have to correct price
signals to a politically difficult level for long periods before less
resource consuming innovations relieve the pressure. Case stud-
ies and survey research identified overlapping cognitive, social,
3Often regulatory push was found to induce greener innovation (Ashford et al.,
1985; Howes et al., 1997). Significantly, it was the way these regulations were
implemented that mattered, and the extent to which regulators were able to act
as knowledge brokers between firms adapting innovative ideas, technologies and
practices (Smith, 1996; Gouldson and Murphy, 1998).
4Neo-classical environmental economists found a receptive policy audience
amongst the New Right for their market-based ideas. The environmental regulations
of the 1970s became ideologically tarred as too restrictive and burdensome on busi-
ness. Environmental taxes and tradable quotas were the preferred, market-friendly
approach (rhetorically at least) to inducing cleaner innovation in firms. In prac-
tice, regulations can be flexible and retain advantages that ensure their continued
importance within environmental policy mixes (Smith and Sorrell, 2001).

institutional and political barriers, in addition to narrow market
barriers, as critical for greener innovation (Fischer and Schot, 1993;
Howes et al., 1997; Kemp, 1994a,b). A wider analytical perspective
needed to include these non-market considerations in its analysis.
As an illustration, Clayton et al. (1999) considered the differ-
ent knowledge capabilities and extensiveness of actor networks
associated with a variety of cleaner innovation cases (Fig. 1). This
mapping can be extended to consider the distribution of other
resources required for each type of environmental improvement in
their scheme, such as equipment, skills, finance, supportive infras-
tructures, and institutional support.
As with an earlier generation of critical studies on the under-
standing of innovation dynamics in neo-classical economics (e.g.
Dosi, 1982; Nelson and Winter, 1982; Dosi, 1988), the cleaner inno-
vation literature found price signals to be necessary, yet insufficient
to assure innovative responses on the supply-side of the market.
Evolutionary perspectives offered a more nuanced way of consid-
ering the greening of production processes by bringing the factors
into view that shape innovative activity on the supply-side (Green
et al., 1994). This analytical broadening did not simply consider R&D
subsidies as a complement to eco-taxes. Other institutional factors
were important for the innovation of cleaner production processes,
including search routines, knowledge capabilities, prevailing tech-
nology paradigms and regimes (Kemp, 1994a,b).
2.3. A further broadening in analytical perspective: greener
innovation systems
Firm-level studies of environmentally oriented innovation pro-
cesses continue to be an important activity, as well as supporting
a large consultancy sector. This is where much of the hard slog
towards a shift in industry structures needs to take place. It is
an area of policy and business activity, however, that can bene-
fit considerably from the analysis of broader innovation systems
in which firm-level activities are embedded (Freeman, 1992). This
refers to institutional frameworks influenced by policy-makers and
broader governance processes, the system of innovation, as it were.
Much depends on e.g. provision of workers with the requisite
skills, the integration of cleaner technologies in network infrastruc-
tures, safety standards, planning procedures and other market rules
which have an effect for facilitating or hampering environmental
innovations. The innovation studies literature suggests environ-
mentally oriented innovation policy must take a broader systems
perspective, recognising institutions operating beyond the firm
and networks of different organisations such as firms, universities,
financial service providers.
Recognising that the capabilities of individual organisations
to innovate, as well as their broader selection environments, are
constituted by more complex processes opens analysis to related
practitioner routines, skills and training, governing institutions,
facilitating infrastructures, and effective and prospective market
demand. This is an insight which is at the root of the systems
perspective in innovation studies and various strands of research
focusing on the structure and performance of national, sectoral,
regional or technological innovation systems (Lundvall, 1992;
Breschi and Malerba, 1997; Truffer, 2008). Central to this innova-
tion systems perspective is how this work is distributed across the
research, government and business sectors.
The greener innovation systems perspective adapts innovation
system analysis by adding an interest in how the functioning of the
innovation system becomes subordinate to the sustainability quali-
ties of its outputs (Green et al., 1994). Recent work on technological
innovation systems (TIS), for instance, developed with a concern
for the success of innovations that are expected to be particularly
favourable from an environmental point of view (e.g. renewable
energy technologies). Extensive literature review provided a frame-
work for explaining the success of innovative technologies which
can also be used to strategically guide the development of desired
technological innovation systems (Jacobsson and Bergek, 2004). A
functions approach is deployed to identify those properties of a
technology innovation system that are needed in order to intro-
duce cleaner technologies successfully. These functions include:
experimentation by entrepreneurs; knowledge development and
diffusion; providing orientation to search processes; creating mar-
kets; mobilising resources; and securing policy legitimacy (Hekkert
et al., 2007).
As with earlier innovation system formulations, interest in
wider institutional, historical, material, cultural and geographical
contexts takes the form of a set of (exogenous) structural param-
eters that contribute to explanations of innovative success (or
failure) of a core innovation system (Bell, 2007). The core system
is comprised of networks of firm capabilities, knowledge infras-
tructures and proximate policy and market institutions. Innovation
systems analysis covers this core well (Edquist, 2005). As the TIS lit-
erature points out, some of the difficulties in establishing greener
innovation systems can be explained by the absence of certain core
functions or because the system is unable to align functions. How-
ever, it remains unclear where these absent functional capabilities
come from, or how they develop. We do not learn much in the TIS
literature about difficult governance questions such as how to iden-
tify ‘sustainable’ technologies and how to prioritise them. Much of
that explanation rests in the broader societal contexts in which
specific innovation systems operate, and which tend not to be con-
sidered in dynamic interaction with the core (Markard and Truffer,
2008; Bell, 2007).
So whilst innovation systems analysis can help explain the rel-
ative success of specific cleaner technologies, analysis is often in
a situation of needing to explain the difficulties of making such
“green” innovation systems come about. Analysis needs to focus
on the way broader contexts put pressure on innovation systems
to become greener and inform their reconfiguration.
The preceding remarks have a crucial implication. Reconfigured
and reprioritised innovation systems may contribute to sustain-
able development through provision of greener goods and services.
But the possibility to do this reconfiguring will be structured (in
both enabling and constraining ways) by wider contexts that frame,
motivate and interpret innovation system activities, and which may
actually attenuate the benefits of individual cleaner innovations.
This broader analytical perspective is recognised in the innovation
systems literature, as is a concern to explain the directionality of
the technological trajectories that ensue (Bell, 2007; Nelson, 2008;
Von Tunzelmann et al., 2008).

2.4. A further broadening in problem framing: system innovation
for sustainability
It is the broadening of problem framing to a perspective on
‘systems innovation’ that poses an additional challenge to the ana-
lytical framing of innovation systems. Systems innovation refers
to the renewal of a whole set of networked supply chains, pat-
terns of use and consumption, infrastructures, regulations, etc.,
that constitute the socio-technical systems which provide basic
services such as energy, food, mobility or housing. This broaden-
ing of problem framing goes beyond isolated products, processes
or technologies. It acknowledges difficulty in evaluating the sus-
tainability of isolated technologies, if not analysed as embedded
in a system context.5And it acknowledges strong interdependen-
cies between various elements of socio-technical systems which
impede radically new ways of organising socio-technical provi-
sion (e.g. renewable energy, organic agriculture, public transport
or ecological building).
Until recently the focus of environmentally oriented innova-
tion studies has remained largely upon innovations to individual
goods and services. A greener innovation system may produce more
eco-efficient products or services, or even enable industry clusters
to develop more closed-loop processes. But the relative improve-
ments they deliver can be undermined by absolute increases in
consumption. A need for step-jumps in absolute performance, such
as 80% reductions in carbon emissions over the next generation, or
factor ten improvements in resource efficiency, implies changes
at the level of entire socio-technical systems. These system inno-
vations, such as transformative innovations that overhaul food
systems or waste systems, involve purposeful changes in prevail-
ing techno-economic paradigms and system architectures (to use
the Freeman-Perez typology of innovation). As such, systems inno-
vation takes an even broader view than earlier perspectives on
innovation and sustainable development; making it far more ambi-
tious and posing even greater analytical and governance challenges.
As Weber and Hemmelskamp (2005, p. 1) put it, sustainable
systems innovation implies:
major changes are required along the entire production-
consumption chain, its flows, its multi-level architecture, its
institutions and structures, and – not least – the behaviour of
the actors involved in it, from resource extraction to the final
consumption of goods and services.
The challenge of sustainable development is increasingly under-
stood in terms of ‘transitions’ to more sustainable socio-technical
systems. The 2002 World Summit on Sustainable Development in
Johannesburg initiated cross-cutting programmes for transforming
sustainable production and consumption systems (the UN Mar-
rakech process). The UK government announced a Low Carbon
Transition Plan for its economy in 2009, joining the Netherlands,
Austria, Belgium and Finland with ‘transition’ ambitions (Geels et
al., 2008). Governments, businesses and civil society groups are
considering what reformed innovation policy looks like through
this sustainable socio-technical transitions framing.
Hoogma et al. (2002, p. 5) argue:
‘Ecological restructuring of production and consumption pat-
terns will require not so much a substitution of old technologies
by new ones, but radical shifts in technological systems or tech-
5Special section contributions illustrate an important aspect to transitions, which
is the way the ‘societal function’ is itself altered through transitions between
regimes. Expectations about mobility have, for instance, altered with developments
in the socio-technical systems that move us around (see Shove and Walker, and
Cohen, both in this issue); as have adequate levels of energy service with the devel-
opment of energy systems (see Spaeth and Rohracher in this issue).
nological regimes including a change in consumption patterns,
user preferences, regulations, and artefacts’
This poses a challenging advance on research rooted in more
specific environmental innovation studies of the types mentioned
above (Tukker et al., 2008). Relative to innovations in Fig. 1, ‘systems
innovation’ sits well beyond the top right of that scheme.
Studying food systems, for instance, means technical
elements—physical inputs, plant-breeding techniques, pesti-
cides, harvesting technologies, transport and logistics, food
processing, cooking technology, and so on—are studied in tight
relation to the social elements giving these artifacts meaning and
purpose—such as prevailing attitudes towards farming, ideas about
soil health and nutritional food, official agricultural policy and
price-support mechanisms, organised interests, the structure of
food retailing, shifting trends in food consumption, and other social
considerations, including concern about long-term environmental
sustainability (Smith, 2006). It is the co-evolution of these social
and technical elements that determines the way the food system
is structured and how it performs (Russell and Williams, 2002).
The analytical challenge is to understand these socio-technical
interdependencies as a dynamic system, and then identify how
systems innovation can induce a transition to other, potentially
more sustainable, systems.
So, the key difference between the greener innovation systems
literature and systems innovation (socio-technical transition) lit-
erature is the starting points and focal objectives of each. The
innovation systems problem framing is (predominantly) concerned
with the promotion and introduction of greener goods and services
into markets. The systems innovation literature frames its prob-
lem as concern for the realisation of ‘societal functions’ through
the configuration and alignment of heterogeneous socio-technical
elements and processes, and how these restructure over long peri-
ods of time. Markets are an important part of this broader picture,
but so too are other institutions.
2.5. Another broadening in analytical perspective: transitions in
socio-technical regimes
The challenge then, is to find an analytical perspective on inno-
vation that is commensurate with the extended problem framing
of system innovations for sustainability: how can we understand
innovation processes leading to transformations in socio-technical
systems that help realise broad social functions more sustain-
ably? Two related strands of research help, which are: historically
informed theory for wide-scale changes to technology-in-society;
and, problem-oriented thinking for sustainable transitions.
The first strand provides a ‘quasi-evolutionary’ conceptuali-
sation of historic transitions in societal functions. It combines
sociological appreciation of processes of technology shaping, as in
SCOT, with more structural notions of ‘technological regimes’ and
‘paradigms’ prevalent in evolutionary economics (Rip, 1995, see
Geels’ paper in this special section). Research emphasises the ways
selection environments are anticipated, reinterpreted and (par-
tially) transformed by (networked) innovators (Rip, 1992; van den
Belt and Rip, 1987; Disco and van der Meulen, 1998). Relevant stud-
ies are those interested in how new technologies become involved
in wide-ranging processes of social change (e.g. the move from gas
light to electric light (Schot, 1998), from sail to steam ships (Geels,
2002), the rise of the turbo-jet in aviation (Geels, 2006), improve-
ments in public sanitation (Geels, 2006b). This strand of research is
not interested in normative goals like sustainability.
This historic work extends technological paradigm and regime
concepts, and re-conceives how they shape trajectories of devel-
opment. Earlier work was more interested in the way regimes
operated (Dosi et al., 1988; Nelson and Winter, 1982), and less
440 A. Smith et al. / Research Policy 39 (2010) 435–448
focused in how they related to social institutions beyond markets
and science (e.g. Dosi, 1982; see also Nelson, 2008). As an other-
wise positive review of that literature concluded, ‘how to catch
[paradigms] as they form, and manage the formation and estab-
lishment of new ones, remain very poorly understood and under
researched’ (Von Tunzelmann et al., 2008, p. 482). As we shall see
in the next Section, transitions between regimes are central to the
MLP.
A socio-technical perspective reconceptualises regimes beyond
the core cognitive structures emphasised by Dosi and others (Geels,
2004).6A sociological sensibility extends the regime notion to
embrace institutions (such as regulations and markets), heteroge-
neous networks (including devices and people), user relations, and
social expectations. Mutual reinforcement across these plural pro-
cesses creates the structural patterns that shape innovation and
creates trajectories of social development. The regime of automo-
bility, for example, includes not only paradigmatic technological
designs for cars, but also the specialised road planning authori-
ties, the institutions of the ‘driving licence’ and ‘motor insurance’,
the lobbying capacities of car manufacturers and oil companies,
and the cultural significance of automobility. In combination, these
elements form a socio-technical regime that stabilises the way soci-
etal functions are realised, and gives shape to particular patterns of
producing and consuming mobility.
Transitions in regime structures are consequently seen to
arise through an accumulation of a broader variety of interact-
ing processes than the knowledge base and markets alone. ‘How
technology is shaped by social, economic and political forces alike,
and how, in the same process, technologies and technology sys-
tems shape human relations and societies’ (Rip and Kemp, 1998,
p. 328). So, for example, the transition from a ‘society with candle
and gaslight’ to a ‘society with electrical light’, emphasises some
of the social, political and economic factors facilitating this transi-
tion, as well as the developmental possibilities opened up by the
emergence of new regimes, and the meanings associated with those
developments (Schot, 1998). Transition scholars are interested in
the broader societal transformations arising from the establish-
ment of novel technological regimes, but also how broader societal
developments are effectively selecting between possible would-be
regimes and exerting pressure on them to adapt or causing them
to wither.
Such interests resonate with the concerns of sustainability
researchers, where interest centres upon challenges like transiting
away from fossil-fuelled energy systems and towards low carbon
alternatives (Kemp, 1994a,b; Rip and Kemp, 1998; Smith et al.,
2005). Thus the second strand of research, involving researchers
working in the historical strand, but also in the Constructive Tech-
nology Assessment tradition, is explicitly concerned with broader,
regime approaches to sustainable innovation (Rip and Kemp, 1998;
cf. Kemp, 1994a,b; Rip et al., 1995). Scholars in this second strand
discuss the prospective conditions under which sustainable tran-
sitions in transport, energy, housing and so on might develop (e.g.
Elzen et al., 2004).
Thinking prospectively, many sustainability goals imply tran-
sitions over much tighter time-frames than the historic examples
that inspire systems innovation analysis (e.g. Rotmans et al., 2001;
Loorbach, 2007; see the special issue on transition management in
issue 4, volume 42 of Policy Sciences in December 2009). These goals
include ambitions to reduce anthropogenic carbon emissions by
80% or more within 40 years, or the 2015 target date for Millennium
6Dosi adapted his technology paradigm concept from Kuhn’s ideas about sci-
entific paradigms. Perhaps this explains why Dosi’s definition of technology
emphasises the knowledge embodied in technological practice cf. the materiality
of technology devices?
Development Goals that include reducing by half the proportion of
people without sustainable access to safe drinking water and basic
sanitation. Some transitions, like the move from coal heating to gas
heating in parts of north-western Europe, have proceeded rapidly
(Correljé and Verbong, 2004). Many others arose over five or more
decades. The prospect for sustainability need not be as bleak as the
historic timescales suggest. Arguably, there has been a slow build
up of ideas, experience and green niches over the last 40 years,
going back to the alternative technology movement and public
research programmes of the 1970s (Smith, 2005, 2007). Neverthe-
less, public sustainability aspirations imply a rapid acceleration in
these activities and any systems innovations they may induce.
Sustainability transitions research is engaged in aiding politi-
cal deliberations and governance activities that can accelerate the
take off of some of these green niches, and bring about restruc-
tured production and consumption systems. Researchers in the
Netherlands especially have helped reshape environmental policy
along transitions lines (Kemp et al., 2007; Smith and Kern, 2009).
Researchers in other countries have also been commissioned by
think tanks and policy departments to explore the potential of sys-
tems innovation approaches (Steward, 2008; Scrase et al., 2009).
The multi-level perspective on socio-technical transitions (MLP)
provides them with an alluring framework, both in terms of organ-
ising analysis and ordering policy interventions. It is this framework
this special section considers, and which we introduce in the next
section.
3. The multi-level perspective for analysing sustainable
transitions
The multi-level perspective organises analysis into a socio-
technical system that consists of niches, regimes and landscapes.
This is a nested hierarchy of structuring processes (Geels and
Schot, 2007), analogous to Giddens’ (1984) concepts of reflex-
ive agency and structure. Socio-technical regimes constitute the
mainstream, and highly institutionalised, way of currently realising
societal functions. Change within the regime tends to be incre-
mental and path dependent. Regimes also exert a structuring force
upon novel alternatives, which arise in niche spaces. In a Kuh-
nian vein, regimes tend to produce ‘normal’ innovation patterns,
whilst ‘revolutionary’ change originates in ‘niches’. The implica-
tion is that the quality of incremental innovations subsequently
generated within a new regime will be radically different to those
under the preceding regime. Finally, both niches and regimes are
situated within a broader landscape of social and physical factors
that provides a macro-level structuring context. Over time, the rise
of some regimes can prove quite influential upon broader land-
scape developments. An example is the catalytic effect aeromobility
and communications regimes have upon socio-economic globali-
sation (and which reinforces the continued development of these
regimes) (see Cohen, this issue).
3.1. Socio-technical niches
In the MLP, transitions are crucially dependent upon activities
within niches, where selection pressures prevailing in regimes are
less evident. Niches provide ‘protective spaces’ for path-breaking,
radical alternatives whose performance may not be competitive
against the selection environment prevailing in the regime (Rip,
1992,p.91;Kemp et al., 1998). Niche protection can be afforded
through lead markets, subsidised projects for research demonstra-
tion and learning, or specific cultural milieu of early adoption and
experimentation. Niches that provided seeds for transitions his-
torically had to overcome the constraining influence of regimes,
branch out, link up with wider change processes, and drive trans-
A. Smith et al. / Research Policy 39 (2010) 435–448 441
formations in those same regime structures over the longer-term.
Many niches are not successful in expanding, or even surviving for
a long time.
Sustainable niches comprise networks of real world exper-
iments with socially and ecologically benign socio-technical
practices The actors (producers and users) undertaking these
experiments are relatively more supportive of the social and envi-
ronmental qualities of the niche socio-technical practice, and more
forgiving of teething troubles, owing to their different expectations
of future performance compared to regime members. The norms in
the niche are different compared to the rules in the regime but
tend also to be less established and relatively instable. Whilst ‘out-
siders’ can be important instigators of niche developments, such as
environmental activists in the early development of modern wind
energy, actors established within the regime must become involved
in those activities for wide-scale influence, such as large energy util-
ities in wind. Niche success ultimately rests upon broader circles
of more powerful actors becoming involved in ways that mobilise
widespread social legitimacy (Schot, 1998; Späth and Rohracher,
this issue).
Niche development is predicated upon valuable lessons being
generated, supportive institutional requirements becoming better
articulated, and enrolling commitments from a growing network
of actors (including potential investors and users from more main-
stream settings) (Raven, 2006). Niche actors need to perform
considerable cognitive, institutional, economic and political work:
they have to be persuasive to a variety of constituencies on dif-
ferent terms (Smith, 2007; Hendriks and Grin, 2007). In these ways
niches compete with the incumbent regimes, outperform them and
take over. The expectations motivating the niche pioneers have
to align with expectations prevalent in the regime (Schot, 1998;
Smith, 2007). As such, niches are a source for transformative ideas
and capabilities, but not blueprints. Their potential is constrained,
enabled and interpreted through the more powerful structures of
the regime (Roep et al., 2003; Grin et al., 2004; Bos and Grin, 2008).
3.2. Socio-technical regimes
Socio-technical configurations in regimes are established as
the stable and dominant way of realising a particular societal
function. Socio-technical regimes are structures constituted from
a co-evolutionary accumulation and alignment of knowledge,
investments, objects, infrastructures, values and norms that span
the production-consumption divide.7These heterogeneous con-
figurations are the prevailing means for realising key societal
functions. Institutional and material interdependencies constitut-
ing the regime mean realignments tend to be path dependent and
incremental. It is this dynamic structure which sustainable niches
must overcome if they are to unsettle the regime and seed a tran-
sition.
7There are ambiguities in the definition of regime in the literature. Geels (2002),
whilst not yet shifting terminology from ‘technological regimes’ (as in evolutionary
economic theories) to ‘socio-technical regimes’, nevertheless takes a broader analyt-
ical view: guiding principles, technologies and infrastructures, industrial structure,
user relations and markets, policy and regulations, the knowledge base of the
regime, and culture (the symbolic meanings underpinning the material practices
in the regime). Later, Geels (2004) considers regimes on more institutional terms,
as the ‘rule set’ that guides the development of material socio-technical systems—a
depiction that is actually closer to (evolutionary economic) innovation theory. In a
thoughtful review, Markard and Truffer (2008) note this tension between institu-
tional understandings of the regime, and more material understandings that include
the actors and artefacts whose practices develop the rule set (e.g. Verbong and Geels,
2007). It is difficult to conceive a pattern of socio-technical practices reproducing
without the presence of institutions, just as it is difficult to see how institutions can
persist without their re-enactment through networks of actors engaged in material
practices (Smith et al., 2005).
Dynamics within the regime derive from partially autonomous
developments within regime components, such as firm R&D,
or government regulations, which generate misalignments and
realignments and incremental responses. Dynamism may also
occur in response to landscape developments (see below), or
through interaction with associated regimes (Raven and Verbong,
2007; Konrad et al., 2008). These sources of dynamism, and the
tensions they create, open windows of opportunity for niche alter-
natives to compete for attention and influence.
3.3. Socio-technical landscapes
The macro-level socio-technical landscape provides a highly
structural context for both the regime and niches. The MLP land-
scape includes processes that span societal functions and unfold
autonomously of particular socio-technical regimes. Landscape
processes include environmental and demographic change, new
social movements, shifts in general political ideology, broad eco-
nomic restructuring, emerging scientific paradigms, and cultural
developments. Landscapes provide an influential backdrop with
ramifications across a variety of regimes and niches: providing
gradients and affordances for how to go about establishing socio-
technical configurations that serve societal needs (Geels and Schot,
2007).
Landscape changes are a source of pressures for change on the
regime level; they prompt responses from within the regime; and
they generate opportunities for niches. At times, landscapes can
work to reinforce regime trajectories. At other times, landscape
developments place some regimes under considerable stress in
ways that undermines satisfaction with their performance, and
prompts consideration of niche alternatives.
Regimes are increasingly confronted with new sustainability
criteria which were never considered during their installation.
Growing environmental awareness is a socio-cultural development
that can be considered a landscape process, and which is ques-
tioning the performance of multiple regimes, whilst generating
opportunities for niches. These are the kinds of multi-level pro-
cesses that sustainability analysts seek to map and understand, and
which policy-oriented advocates try to instigate and govern.
3.4. The allure of the MLP
As our concern for sustainable development has broadened,
so the demands on innovation have become more profound and
pervasive. Whatever the specific feature of sustainable develop-
ment under consideration (e.g. deep cuts in greenhouse gases, step
change improvements in resource efficiency, delivering the Mil-
lennium Development Goals)—the need to escape lock-in, deflect
path dependencies and transform socio-technical regimes becomes
paramount. The history of innovation studies for sustainable devel-
opment can be explained as a process of linking broader analytical
frameworks to successively larger problem framings.
The MLP satisfies this logic. It argues ‘normal’ innovation pat-
terns reproduce broad socio-technical regimes. Regime shifts occur
through inter-linkages and interactions between multiple devel-
opments on three levels. These involve the rise of both strong
socio-technical alternatives in niches and favourable openings
in regime selection environments. The latter is associated with
the unsettling of regimes arising from landscape developments.
Throughout, it is crucial to recognise these transition processes
involving purposeful actors in normative questions operating
through structured relations (Rip and Kemp, 1998; Smith et al.,
2005; Geels and Schot, 2007).
The allure of the MLP is that it provides a relatively straight-
forward way of ordering and simplifying the analysis of complex,
large-scale structural transformations in production and consump-
442 A. Smith et al. / Research Policy 39 (2010) 435–448
tion demanded by the normative goal of sustainable development.
Its conceptual repertoire links specific innovation activities con-
figured in niches with structural transformations in regimes. Its
terminology of niche, regime and landscape provides a language for
organising a diverse array of considerations into narrative accounts
of transitions. However, such abstract parsimony carries poten-
tial pitfalls which have to be approached with care. There is a
tension between appreciating the bigger picture whilst maintain-
ing a tractable parsimony in analysis. The MLP may help people
simplify and intervene reflexively, but must not become counter-
productively simplistic in its abstraction (Sayer, 1992).
The existing literature contains some cautionary criticisms and
some responses. Key contributions have appeared in Research Pol-
icy. These are picked up in Section 5, so only some brief remarks
are made here. Hommels et al. (2007) question the importance and
desirability of niche protective space compared to the significance
of immediate exposure of novelties to the selection environments
prevailing in regimes. Smith et al. (2005) caution against too much
emphasis in niche-derived agency in transitions, arguing that incre-
mental reforms in regimes can lead to radical transformations over
the long periods under consideration. They suggest a typology of
transition pathways (also, Geels and Schot, 2007), and suggest ways
that power and agency could be incorporated more centrally into
MLP analysis. Shove and Walker (2007) question whether sustain-
able transitions are really as tractable to policy-makers as implied in
some interpretations of the MLP (Rotmans et al., 2001). Like Smith
and Stirling (2007), Shove and Walker call for a more reflexive
and politically informed appreciation of the way these systems are
socially constructed. Markard and Truffer (2008) consider how the
MLP can be positioned much more explicitly and fruitfully in rela-
tion to technological innovation systems, which reflects the flexible
possibilities for the MLP. Genus and Coles (2008) are critical of this
flexibility, arguing that there has been a lack of (methodological)
coherence in empirical studies using the MLP. The contributions to
this special section pick up on many of these issues, and identify
others too (such as the geography of transitions).
4. The papers contributing to this special section
The workshop from which contributing papers were drawn was
prompted by the debates above, and attracting a growing network
of researchers. In Section 5, we discuss challenges presented by the
contributing papers and the wider literature. Before doing so, we
introduce each paper here.
Philipp Späth and Harald Rohracher use the MLP in prospec-
tive mode to consider efforts for sustainable energy autonomy in
Austrian regions. They are interested in the coalitions of stake-
holders formulating visions for sustainable energy niches in their
region. They consider how these visions are formed in the context
of increasingly less favourable attitudes towards existing energy
regimes. The institutionalisation of regional visions is found to exert
an influence over the promotion of alternative niches and other
transition processes. As such, their analysis emphasises the roles of
discursive and institutional processes in the constitution of regime
transformation.
In contrast, Maurie Cohen’spaper considers a niche develop-
ing in the opposite direction to sustainable energy ambitions.
He uses the MLP to explain a personalised aeromobility niche
in the US. It is a sobering reminder that not everyone shares
even a very general vision for sustainable transitions. Problems
within the current mass aeromobility regime relating to passen-
ger convenience and comfort, coupled with organisational and
technological innovation, are providing opportunities for person-
alised aeromobility: precisely at a time when aviation emissions
are amongst the fastest growing contributions to climate change.
In contrast to recommendations for nurturing sustainable niches,
Cohen’s analysis poses the challenge of discouraging unsustain-
able niches in the making, and whose relative relationship to
the regime advantages them compared to the greener alterna-
tives.
Mobility is one of the case studies in the paper by Elizabeth Shove
and Gordon Walker; this time looking at the congestion charging
experience in London. They adopt practice theory as an alterna-
tive to MLP thinking about transitions. Practice theory emphasises
the constant interplay of technologies, meanings and people in
everyday practices. They argue it is the aggregation of these thou-
sands of practices in response to (or despite) the congestion charge
that effectively constructs the new mobility regime in London. A
second case study analysis into transitions in cleanliness, specif-
ically showering, emphasises that transitions perspectives, have
to attend to the destabilisation of entrenched consumption much
more assiduously.
London pioneered the large-scale implementation of a conges-
tion charge. Many other local authorities and stakeholders in cities
around the world also seek innovative, sustainable infrastructures
and services. Hodson and Marvin consider the ways the MLP can
help analysts make sense of city-based activities. They discuss the
position and role of cities as niche pioneers and as bearers of socio-
technical regimes. Analysis considers the extent to which cities
can shape socio-technical transitions and effectively carve out their
own sustainable destinies. There are parallels here with Späth and
Rohracher’s paper. Place-based considerations of agency in sus-
tainability transitions emphasise questions of geography and scale,
and how processes reproducing niches, regimes and landscapes are
spatially (and temporally) distributed across policy jurisdictions at
different scales.
The penultimate paper to this special section considers pro-
ducer responsibility initiatives by the European Union that attempt
to induce radical changes in the production and consumption of
electronic products. The manufacture, use and disposal of elec-
tronics are highly dispersed (often beyond the jurisdiction of the
EU). Hagaleskjær Lauridsen and Jørgensen use the MLP to delineate
and explain changes in electronics goods regimes, and that helps
explain why this single measure actually led to innovation in the
more tractable waste regime, rather than eco-designed electron-
ics.
Effectively, each contribution to this special section is zooming
into specific aspects of the MLP. Whether formulating sustainable
visions and niches (Späth and Rohracher), studying unsustain-
able niche-regime developments (Cohen), emphasising everyday
practices in regime reproduction (Shove and Walker), the role of
cities in transitions (Hodson and Marvin), or the insights the MLP
provides for specific policy measures (Hagaleskjær Lauridsen and
Jørgensen). In the final contribution, Frank Geels, a pioneer in MLP
thinking, considers how other social theories can be brought in
to enrich these specific aspects. He relates the ontologies of dif-
ferent social theories to sustainable transitions. He uses this to
reflect on the development of the MLP thus far, and the poten-
tial for cross-overs with compatible theories. Frank concludes
that the MLP provides a device for organising the complemen-
tary analysis of specific transition processes using different social
theories.
5. Research challenges in this special section
A number of research challenges associated with the MLP or sus-
tainability transitions arise from these contributions. The purpose
in this section is to elaborate upon some of these research chal-
lenges, and contextualise them within the literature to date. These
research challenges are
A. Smith et al. / Research Policy 39 (2010) 435–448 443
•relations between the conceptual levels of niche, regime and
landscape;
•plural regimes and niches in interaction;
•the geography of transitions;
•empirical operationalisation of concepts; and
•governing regime transitions.
The first four of these challenges relate specifically to the MLP,
whilst the last relates to sustainability transitions more generally,
whether one uses the MLP or not.
5.1. Relations between niche, regime and landscape levels
The MLP posits that the way niches, regimes and landscapes
interact determines the characteristics of a transition. Cohen shows
in detail how a variety of landscape tendencies entrench growth
in aeromobility. Simultaneously, aeromobility regime dynamics
exhibit features that make mass aeromobility less attractive to par-
ticular users. As a result, a variety of entrepreneurs have launched
novel modes of personal aeromobility. Cohen argues that a cru-
cial factor in the influence of the personal aeromobility niche
is the fact that it provides a new hybrid for the aeromobility
regime, rather than challenging that regime. Cohen’s focus is sim-
ilar to a scheme proposed by Raven (2006), who explains niche
influence by considering the stability of the regime relative to
the stability of the niche practice. However, this need not mean
the aeromobility regime is equally susceptible to all robust niche
alternatives (like high-speed rail). Cohen’s niche case exploits
regime openings successfully because the resulting hybrid rein-
forces regime actor interests rather than empowering radical
transitions.
The specific mechanisms underpinning these interactions prove
to be far more complex than early versions of the MLP implied.
Successful niches exert influence not solely by growth and dis-
placement of the regime, but more often we see a variety of forms of
synthesis and reaction between niche elements and regime compo-
nents (Geels and Schot, 2007). Elements of a radical niche practice
can be co-opted by a regime without unduly unsettling and trans-
forming it (Smith, 2007). Distinctive boundaries between niche and
regime become less clear empirically as the MLP implies.
Typologies of multi-level interaction and transition pathway
have been developed (Smith et al., 2005; Geels and Schot, 2007).
Whatever the merits and drawbacks of these typologies, they
remind us that each transformation is historically contingent. It
is reasonable to anticipate environmentally sustainable transitions
following diverse pathways. Frank Geels’ article argues these niche-
regime relations can be better analysed by considering how other
social theories deepen the focus on specific causal mechanisms.
A structuralist ontology could, for instance, shed light on why
organic food has been co-opted by the food regime rather than
transformed it; though reactions to capture have spawned localised
organic configurations that continue to challenge regime practices
(cf. Smith, 2005). The MLP serves to keep these deeper investiga-
tions and theorisations in context and helps relate them to one
another.
5.2. Plural regimes and niches in interaction
The contribution by Erik Hagelskær Lauridsen and Ulrik Jör-
gensen underscores the need to consider interacting regimes
in transitions analysis (see also Raven and Verbong, 2007). The
response of consumer electronics businesses to EU producer
responsibility policy has been to work with waste firms to innovate
materials handling procedures (i.e. alter the waste regime), rather
than redesign socio-technical configurations in consumer electron-
ics. Whilst probably better than earlier disposal practices (though
Hagelskær Lauridsen and Jörgensen have their doubts), the waste
management innovations prompted by the WEEE Directive are not
contributing to electronics eco-designs. The difficulty was not that
policy mobilised both regimes, but that it did so in a way that ren-
dered sustainability logics in the electronics regime subordinate to
the business logic of the waste regime. The Directive did not address
eco-design activities directly, providing little protective space for
niche developments in that direction.
Complex reality confronts the MLP picture of a homogenous
incumbent regime challenged by a self-evidently sustainable niche.
In practice, more or less (un)sustainable niches contend to influ-
ence regimes in interaction. Cohen’s article suggests analysis of
green niche dynamics consider them not just in the context of
the current regime, but also in competition with unsustainable
practices in niches more closely aligned with the interests of the
regime (see also Geels and Schot, 2007). Others have also argued
that sustainability analysis must include the counter-veiling effects
of unsustainable transitions in the making (Shove and Walker,
this issue). There is a contest between various niches, each posi-
tioned differently in relation to regimes (Scoones et al., 2007). The
challenge is whether the overall performance of different niches
in interaction with regimes can be recognised sufficiently early
to pre-empt lock-in to unsustainable developments. Uncertain-
ties inherent in the co-evolution of niche novelties and regime
elements suggest an added dimension to Collingridge’s dilemma
(Collingridge, 1980).
Considering niches and regimes under conditions of plural com-
petition re-introduces some complexity back into the MLP. Shove
and Walker go even further, and argue that even a plural framework
fails to capture the sheer complexity and contingency of sustain-
able and unsustainable developments. Their practice-oriented view
perceives countless everyday activities continually reconstituting
and reproducing fluid socio-technical configurations. Partitioning
these practices into different niches and regimes misses the point
that systems (of practice) are always in transition.
Nevertheless, Shove and Walker do recognise patterns and sta-
bilities in daily life. The question is whether patterns of practice can
be usefully associated with niche and regime concepts. Some peo-
ples’ practices involve greener forms of socio-technical configuring
than forms common to the majority of practitioners. Can we aggre-
gate greener socio-technical practices into different niches; and are
some practices so routine, stable and pervasive that they constitute
a regime? Moreover, practitioners are limited in their capacity to
configure by the institutions and infrastructures in which they are
situated (Hand et al., 2005). So whilst practice theory forces a more
careful analysis of the constitution of niches and regimes, we feel
one must not disregard the regimes that make available the mate-
rial elements of a practice, and their institutions that structure the
repertoire of possible practices.
5.3. The geography of transitions
The MLP is interested in the socio-technical transformation of
‘societal functions’. The role of places and spatial scales in these
transition processes has not been an explicit issue of concern. The
tendency has been to presume regimes operating at a national
scale, perhaps for reasons to do with nation-state policy audiences.
Yet in practice, we see many places, such as villages, cities and
regions, wondering how they can transform their mobility, energy,
waste, housing and other systems into more sustainable forms.
They confront processes that operate beyond their jurisdiction, e.g.
the ownership of local infrastructures by multi-national utilities,
investments from globally mobile capital, niche alternatives pro-
moted by global civil society, a neo-liberal ideological landscape,
or the standards for connecting regime components set by interna-
tional committees. Clearly, this geography matters for sustainable
444 A. Smith et al. / Research Policy 39 (2010) 435–448
innovation, but research is only beginning to explore how this geog-
raphy influences transitions.
Two contributions to this special section anchor their analy-
sis of transitions in places. Neither the study of Austrian energy
regions by Späth and Rohracher, nor the analysis of world cities by
Hodson and Marvin, presumes a complete analysis of the geogra-
phy of transitions. But each does urge the MLP to appreciate the
multi-scalar characteristics of its conceptual levels, and to consider
the consequences for analysis. Their articles suggest that paying
more attention to the places were (distributed) regime changes
encounter a variety of niche experiments will yield additional
insight into the relations between niche dynamics and unsettling
regimes.
Hodson and Marvin consider the multi-scalar challenges
confronting world cities seeking to sustainably develop the socio-
technical regimes upon which they depend. The MLP provides a
useful framework for understanding the success of city strategies
towards either autonomy from or integration with other places.
These strategies, if successful, require transformations to multiple
regimes. Crucially, they are predicated upon a re-scaling of regimes
in ways that make them more amenable to the collective will and
innovative activities of city-scale actors.
The importance of specific sustainability visions for mobilisa-
tion and coordination is important here. The production of these
visions needs to engage, mobilise and coordinate actors across
scales, and must help (re-)define and align territorial and regime
interests. Hodson and Marvin point to the role of mobile inter-
mediary organisations operating between cities and the spatially
distributed regimes upon which city strategies depend. Showcase
projects that demonstrate and develop niche socio-technical con-
figurations are also identified as important. These showcases satisfy
the local need, whilst promising exportable lessons, products and
services.
Vision and coalition building processes are at the heart of the
analysis of Austrian energy regions by Späth and Rohracher. They
emphasise two advantages for places in the negotiation of shared
visions. First, places bring meaningful historical and social narra-
tives into the realisation of abstract goals. They generate regionally
relevant visions whose symbolism and specificity carry greater
moral authority as a result (e.g. ‘energy security’ cf. ‘protecting
Murau by building a local bio-energy economy’). Second, regions
provide a ‘warmer and more fluid ground’ for political delibera-
tion (Healey et al., 2003, p. 86), where place-identity (reflected
in ‘public sentiments’), local knowledge and relational resources
may be mobilised for innovative practices (Healey et al., 2003,p.
86; cf. Schön and Rein, 1994, pp. 176–178). However, this is an
empirical question. There will be places so riddled with problematic
power relations and factions that warm and inspiring sustainability
visions do not hold.
Aspiring cities are joining together to lobby for support at the
international level (Betsill and Bulkeley, 2008), and these networks
can nurture the development and diffusion of niche alternatives
by connecting sustainability projects together. Nevertheless, it is
asking a lot of city or regional scale visions to mobilise coalitions
capable of unilaterally transforming regimes, especially in cases
where influential regime reproduction operates beyond the city
or regional scale. The WEEE Directive illustrates some of these
scalar difficulties. Innovations in the gathering and processing of
wastes close to points of disposal seems easier compared to coor-
dinated ecological redesigns across spatially distributed production
and consumption chains. In a sense, the response to the producer
responsibility policy has been to develop an end-of-pipe regime,
rather than fundamentally clean up the electronics regime. This is
not solely down to geography, but part of the explanation lies in the
spatial distribution of the regimes and their (lack of) congruency
with the political jurisdictions trying to induce a transition.
5.4. Empirical operationalisation—a need for reflexivity
Making the core concepts of niche, regime and landscape opera-
tional for empirical research is a question of bounding, partitioning
and ordering the system under study. Any attempt at bounding
and analysing complex, emergent socio-technical systems will nec-
essarily be partial, situated and temporary (Scoones et al., 2007).
Whether drawing upon qualitative evidence or quantitative mea-
sures based on indicators, there is considerable work to do in
formalising the MLP into more detailed methods (Haxeltine et al.,
2008). There are few widely shared analytical rules for cutting into
the complex configurations under study and abstracting an objec-
tive socio-technical system (Genus and Coles, 2008). As Geels points
out (this issue), formal quantitative approaches may be limited to
relatively stable socio-technical situations where parameters and
characteristics are well known. However, the majority of transi-
tion studies, like those in this special section, address emergent
and reflexive phenomena and find qualitative narrative accounts
helpful.
Of course, transition research is not unique in its sensitivity to
analytical framings. The instrumental purpose for sustainability
transitions research accentuates the implications, since the ways
in which these concepts are used has repercussions for transitions
as a governance activity. Shove and Walker (this issue) emphasise
how socio-technical ‘systems’ are constructed by subjects engaged
in configuring, including researchers (see also Smith and Stirling,
2007). Philip Späth and Harald Rohracher convey this quite vividly
for the case of Austrian energy regions. Differently situated par-
ticipants in the region brought their different understandings and
interests in energy provision to the negotiations. A shared framing
of the current energy regime and sustainability issues was negoti-
ated. Participants envisaged alternative niche configurations, and
sought a degree of congruency between the interests involved.
Common framings of the ‘system’ are reached through negotia-
tion, informed by diverse knowledge and experience of the way the
‘system’ satisfies particular human needs (which are themselves
understood in different ways).
The contributions suggest it is not precise definition of niche,
regime and landscape that is paramount, so much as what each
conceptualisation does. As with other critical social science activ-
ity (Sayer, 1992), the point of sustainable transitions research is
to engage subjects in processes of reflection in ways that feed
back into their practices, contributing to a re-orientation towards
sustainable development (Loorbach, 2007). Thus the operationali-
sation of the MLP empirically requires reflexivity on the part of the
analyst and sensitivity towards the task in hand.
5.5. Governing sustainability transitions
Regimes are a de facto form of governance in the sense that they
structure and order the interaction of material artifacts and social
processes (Rip, 2006). In contrast, here we consider purposeful gov-
ernance for sustainable development, and analysis for deliberate
policy aiming to transform regimes. Geels and Schot (2007) sug-
gest that socio-technical rule sets are constantly maintained and
re-made through the interactions of actors in regimes and niches.
Rules do not solely constrain but also enable actors to participate
in socio-technical system development. In their view, social agency
for sustainable development derives from an ability to modify and
replace rule sets.
The contributions in this special section suggest rule-based pro-
cesses need not be so clear cut. Socio-technical regimes can prove
resistant to governance intentions (e.g. the congestion charge and
producer responsibility). Any policy measure, no matter how well
it is understood, creates diverse responses that are difficult to know
precisely beforehand. Indeed, part of the explanation for the shape
A. Smith et al. / Research Policy 39 (2010) 435–448 445
of the policy measure rests upon earlier processes and problems
emanating from the socio-technical regime. There is a need to
explain how and why individual agents are able to reform the rules
in desirable directions, in the context of regimes and niches, thus
dealing with the politics essential to transitions.
The London congestion charge discussed by Shove and Walker
is a policy whose ultimate effect is not solely determined by polit-
ical authority, but also by adaptations to the mobility practices
of Londoners and visitors. This is obvious. Yet for policies to gain
support, they need to underplay this problem of anticipation and
pretend they are capable of assuring desired re-configurations (e.g.
Lindblom, 1965, 1990; Majone and Wildavsky, 1978; Elmore, 1979).
Shove and Walker’s study emphasises an additional tendency in
transition policies, which is to make an a priori us-them distinc-
tion between governors and governed. This neglects the role of
both sides in explaining changes in socio-technical transitions. The
analysis of regime responses to the WEEE Directive by Hagelskær
Lauridsen and Jörgensen reinforces this point. Rules, incentives
and norms can be altered by those governing (us), but it is the
responses of many others (them) involved in socio-technical (re-
)configuration that result in, say, the growth of a niche, or the
unsettling of a regime. The success or otherwise of a policy measure
rests in the way governors conceive the operation of the socio-
technical regime in the first place (Smith and Stirling, 2007).
One can go too far in this kind of analysis. Only a handful of
people in London were in professional and institutional positions
to instigate the congestion charging policy (e.g. the Mayor and his
advisors). Certain institutionally privileged actors are able to make
more forceful changes to multi-level dynamics compared to many
others that play a (less strategic) role in reproducing those dynam-
ics (Smith et al., 2005). The structural power of the former derives
from this contribution to maintaining the rules, infrastructures and
values underpinning socio-technical practices.
But this position is not assured. The resources needed to induce
significant socio-technical change are widely distributed. This dis-
tribution obviously includes the regime membership; but it can
involve resources in actor networks beyond the regime (e.g. knowl-
edge about alternatives amongst niche participants; legitimacy
issues deriving from social movements). Contextual developments
in the landscape can shift interdependencies between actors. Power
relations alter. New discourses generate new expectations about
the adequacy of regime performance, such as its sustainability, and
contribute to a re-ordering of priorities. The status of resources and
positions of different actors are cast in a new light, as the Austrian
case indicates.
It might be difficult to know the precise consequences of a pol-
icy measure perfectly in advance, but the centrality of certain actors
in the reproduction of regime and niche socio-technical configura-
tions, and their likely responses to governance interventions, does
suggest we can develop informed expectations about the contri-
bution of various policies to sustainability transitions. Governance
schemes that take socio-technical complexities into account, and
yet retain a sense of which niche-regime-landscape reproduction
processes are significant for transitions, and that target their policy
attention on the key players accordingly, are more likely to gener-
ate effective transition policy. The MLP argues portfolios of policy
measures need to work across: the destabilisation of incumbent
regimes (so that opportunities for structural change increase); the
promotion of radical green niches (so that the portfolio of promis-
ing solutions broadens); and processes for translating ideas and
practices from niches into mainstream settings.
6. Conclusions—towards a future research agenda
The evolution of the MLP in the context of innovation studies
and sustainable development raises some challenging analytical
and practical issues. Many of these remain open and point towards a
vibrant, stimulating and challenging research agenda for the future.
In the discussion here, we have argued that innovation studies have
contributed considerable conceptual insight. This contribution will
continue, but, as the challenges in Section 5illustrate, this will most
likely be made in dialogue with other disciplines, such as political
science and geography. In our view, a number of future research
themes become prominent. These are niche dynamics, unlocking
regimes, spatial aspects of transitions, methods to map transitions,
politics of transitions, and interlinkage with dynamics of gover-
nance.
6.1. Niche dynamics
Future research should continue to improve our understanding
of niches, in terms of their development and their wider influ-
ence. A first issue is to elaborate the conceptualisation of niches
as ‘protective spaces’ in which novel socio-technical configura-
tions take a hold and start to develop. What exactly makes a niche
protective? In which ways are niches different from broader selec-
tion environments? Over what kinds of space does the protective
effect extend (a geographical region, a local jurisdiction, a cul-
tural milieu)? How can evolutionary theories help substantiate the
ecosystem metaphor that informs the niche concept?
A second issue regards the process by which niche innovations
move beyond the initial protective space. How are learning-by-
doing experiences transferred beyond the niche context? How do
practices (embedded configurations) replicate, scale-up or trans-
late into other contexts of application?
A third issue is to move analysis beyond instrumental learning
and expectations about the niche socio-technical configuration. An
important dimension of niche dynamics is the development of a
social constituency for alternative projections of socio-technical
development. Successful niche experiments feed actor networks
with shared expectations, inform the identities of the supportive
coalition, and help orientate interests and social norms. How do
such processes of constituency building take place? Under which
conditions do niche actors come to reflect a common agenda and
mobilise? How do they seek to stretch and shape the space in which
they can prosper (by engaging with agendas of public policy, regu-
latory frameworks, technical standards and finance)? That is, how
does the niche perform as a political actor?
A final niche issue for future research is their interaction with
other niches, and the consequences of plural niches in the context of
a shared regime ‘other’. Competing or complementary niche devel-
opments occur in parallel. How are any interdependencies reflected
in the strategies of niche actors? How do dynamics of contestation
across niches play out in a context where sustainable development
is an inherently ambiguous and contested societal concept?
6.2. Unlocking regimes
Our second suggestion for future research is at the regime level.
In contrast to the large body of research on path-dependency and
lock-in in socio-technical dynamics, relatively little is known about
processes and mechanisms for accelerating the unlocking of socio-
technical regimes. How do regimes open up, erode or decline?
A related issue here is with the roles and strategies of particu-
lar actors in these processes. Taking public policy, we observe a
reluctance to seriously consider how to unsettle and unlock estab-
lished regimes. Perhaps links to the decline of politically salient
industries makes it too great a risk. But what are the conditions in
political economy that allow an accelerated dismantling of unsus-
tainable socio-technical structures, at the same time as creating
space for sustainable alternatives to develop? Public policies tend
to positively engage with promising opportunities (niche building)
446 A. Smith et al. / Research Policy 39 (2010) 435–448
in isolation. Understandably, the politically contentious, coercive
dark side of sustainability transitions, principally putting pressure
on regimes, is done with much greater timidity. How do entrenched
regimes, upon which many of us are dependent, lose their eco-
nomic and social legitimacy? How do shifting alliances of actors
alter power balances in favour or against a certain socio-technical
regime? What is the role of landscape processes such as shift-
ing political ideologies, waves of investor speculation, institution
building and ecological change?
6.3. The spatial aspects of transitions
The MLP provides a useful heuristic for considering the tempo-
ral aspects of transitions. It does this by considering multi-level
processes of socio-technical structuration constituting specific
functional spaces (e.g. mobility, energy, housing). Our third sug-
gested area for future research is how the functional socio-technical
spaces of niche, regime and landscape relate to other dimensions
of space, such as territorial, administrative and communicative
spaces (and their particular topologies). The boundaries of a socio-
technical regime are not necessarily identical with those of a
geographical landscape, a nation state or a social community. How
do socio-technical spaces relate to and cut across these different
spaces? How do emerging communicative spaces such as global
publics or transnational networks of entrepreneurs and profession-
als connect to niches and regimes and establish linkages between
them? Some important insights might be expected for sustainabil-
ity transitions by focusing on both the situated and the distributed
qualities of key, multi-level processes.
6.4. Methodology to map transitions
As with any framework, methodologies for rendering MLP con-
cepts empirically operational are critical to its future success. Some
in the field are looking for standardised indicators, measures and
matrices in order to objectify research on niches, regimes, land-
scapes and their dynamics of change. Principles for bounding and
measuring niches, regimes and landscapes need fleshing out into
rigorous criteria. Comparability and systematic accumulation of
cases will then build theory. Others wish to keep open the flexible
application of the MLP appropriate to specific contexts. The reason
given here is that the nature of the problem studied – structural
and functional transformation – undergoes change whilst being
studied. Methods need to capture the dynamic effects that are pro-
duced? Debate about the methods for mapping transitions needs
to continue through future research.
6.5. The politics of transitions
Sustainability transition studies are trying to combine evolu-
tionary theories of socio-technical change with theories of agency
and strategic decision-making. Future research needs to develop
the MLP’s “quasi-evolutionary” approach further, and provide
deeper conceptual guidance on how to combine (co-) evolution and
agency. How does agency play out in variation and selection pro-
cesses? To what extent do variations and selections arise from the
decisions of particular (networks of) actors? How do decisions and
action strategies reflect and anticipate selection environments and
evolutionary dynamics? It is important to look beyond the “usual
suspects” here (R&D labs, industry, science, and public policy), but
bring in the role of other agents too, such as lifestyle milieus or
social movements who may have an important role for shaping the
selection environment beyond the market.
A broader analytical view on agency makes salient politi-
cal questions about the interests and sources of power shaping
selection environments and generating variations. Studies are
beginning to consider coalition formation around different niches,
and the lobbies for different kinds of socio-technical transitions
(domestically and internationally). Social movements are impor-
tant expressions of and catalysts for changing values and identities,
but how do they engage with socio-technical systems and seek to
transform them?
6.6. Opening the black-box of public policy
Our last suggestion for future research is to incorporate the
analysis of policy processes as part of the study of innovation in
socio-technical systems. The literature, including this special sec-
tion, refers frequently to policies that engage with socio-technical
change, be it through market interventions, R&D funding, provision
of platforms for strategic niche management, or regulations unset-
tling regimes. However, so long as policy remains an external force
or factor of influence, then the conditions for those policies to be put
in place continues to be obscure (Voß et al., 2009). Just how inde-
pendent are policies from what is going on in the socio-technical
realm? Papers in this special section point to multiple inter-
linkages between actors and institutions of markets, technology
and societal demand with those of market regulation, innovation
policy, and environmental governance—be it through education,
professional ties, personal overlap, cultural paradigms, joint ven-
tures, cooperative agreements, cross-financing, lobbying, revolving
doors, or common political agendas. There are long-standing lit-
eratures on regulatory capture, government-industry relations,
clientilism, iron triangles, policy networks, and discourse coali-
tions that can help us ensure analysis of socio-technical regimes
and public policies are more deeply intertwined.
6.7. An open agenda
Our list of future research for the MLP is neither exhaustive nor
exclusive. The MLP is bringing together a growing network of inter-
national researchers with a variety of agendas (now formalising in
an international Sustainability Transitions Research Network). If
a sustainability transitions perspective provides a problem focus,
then the MLP provides a helpful framework for organising the broad
interdisciplinary analysis that is needed. It is clear that this is work
in progress. There is considerable scope for innovation studies to
contribute further; just as it did in the genesis of the MLP frame-
work. Ultimately, the future depends on whether and how research
can satisfy growing demand by policy and society to better under-
stand broad directions of socio-technical change, and how dialogue
can be reflexively guided towards particular sustainability quali-
ties.
