ABSTRACT
Industry utilizes very complex systems, consisting of equipment and their human
interface, which are organized to meet the production needs of the business. Effective
and sustainable energy efficiency programs in an industrial setting require a systems
approach to optimize the integrated whole while meeting primary business requirements.
Companies that treat energy as a manageable resource and integrate their energy program
into their management practices have an organizational context to continually seek
opportunities for optimizing their energy use.
The purpose of an energy management system standard is to provide guidance for
industrial and commercial facilities to integrate energy efficiency into their management
practices, including fine-tuning production processes and improving the energy efficiency
of industrial systems. The International Organization for Standardization (ISO) has
identified energy management as one of its top five priorities for standards development.
The new ISO 50001 will establish an international framework for industrial, commercial,
or institutional facilities, or entire companies, to manage their energy, including
procurement and use. This standard is expected to achieve major, long-term increases in
energy efficiency (20% or more) in industrial, commercial, and institutional facilities and
to reduce greenhouse gas (GHG) emissions worldwide.
This paper describes the impetus for the international standard, its purpose, scope
and significance, and development progress to date. A comparative overview of existing
energy management standards is provided, as well as a discussion of capacity-building
needs for skilled individuals to assist organizations in adopting the standard. Finally,
opportunities and challenges are presented for implementing ISO 50001 in emerging
economies and developing countries.
ISO 50001: Energy Management and Industrial Energy Efficiency
The principal business of an industrial facility is making a profit through
production of goods and services, not energy efficiency. While there has been
movement in industrial markets over the past few years to attribute a higher value to
energy efficiency as a pathway for addressing climate change, typically in response to
emissions trading schemes or shareholder activism, the fact remains that the first priority
of industry is to remain profitable. Recent revival of arguments about how industry
cannot afford to deal with climate change during the current economic downturn brings
this duality sharply into focus. Energy efficiency has demonstrated, time and again, that
2
it saves industrial firms money while having a positive effect on productivity. Despite
this, energy efficiency is still viewed during hard times as a luxury that industry can’t
afford, rather than a strategic investment in future profitability.
This phenomenon cannot be understood in purely economic terms because it is
largely a function of institutional behavior. High energy prices or constrained energy
supply will motivate industrial facilities to try to secure the amount of energy required for
operations at the lowest possible price. But price alone will not build awareness within
the corporate management culture of the potential for energy reduction and cost savings,
maintenance savings, and production benefits that can be realized from the systematic
pursuit of industrial energy efficiency. Managers, whether at the C-level or plant level,
are not typically drawn from the ranks of facility engineering and often have little context
for understanding the economic consequences of energy-inefficient operations and
practices. It is this lack of awareness and the corresponding failure to manage energy use
with the same attention that is routinely afforded production quality, waste reduction, and
labor costs that is at the root of the opportunity.
To be effective, energy efficiency programs need to engage industry at the
management level as well as facilities engineering. Because industrial decision making is
largely driven from the top, failure to engage management results in missed opportunities
for energy efficiency improvement, even when technical staff is educated and aware of
the opportunities. This paper offers up a potential solution, an international energy
management standard, ISO 50001: Energy management and guidance for use, suitable
for any organization, whether industrial, commercial, or institutional.
To build context, an overview will be provided of the current status of energy
management standards, regulations, and specifications in a number of countries as well as
examples of enabling policies and programs used to promote adoption of these standards
by industry. Because of its importance to future climate change mitigation efforts,
particular attention will be given to existing and planned efforts to address barriers to
future adoption of ISO 50001 by industries in developing countries.
The process of developing ISO 50001 will also be described, including
international participation and a discussion of some of the core issues under consideration
by the ISO committee responsible for this work, Project Committee 242 (ISO PC 242).
The paper will conclude with a discussion of the anticipated impact of the standard in
international markets, industrial decision making, and industrial energy policy.
An Overview of Energy Management Standards
The barriers to improving industrial energy efficiency have been well-documented
and include:
• Lack of information regarding energy efficiency;
• Limited awareness of the financial or qualitative benefits arising from energy-
efficiency measures;
• Inadequate skills to implement such measures;
• Capital constraints and corporate culture leading to more investment in new
production capacities rather than energy efficiency; and
3
• Greater weight given to addressing upfront (first) costs compared to recurring energy
costs, especially if these costs are a small proportion of production costs (Monari,
2008).
The purpose of an energy management standard is to provide an organizational
framework for industrial facilities to integrate energy efficiency into their management
practices, including fine-tuning production processes and improving the energy efficiency
of industrial systems. Energy management seeks to apply to energy use the same culture
of continual improvement that has been successfully used by industrial firms to improve
quality and safety practices. An energy management standard is needed to influence how
energy is managed in an industrial facility, thus realizing immediate energy use reduction
through changes in operational practices, as well creating a favorable environment for
adoption of more capital-intensive energy-efficiency measures and technologies.
An energy management standard requires a facility to develop an energy management
plan. In organizations without a plan in place, opportunities for improvement may be
known but may not be promoted or implemented because energy management is not part
of the organizational culture and the normal planning process. This failure to plan
reinforces traditional barriers, which include lack of communication among sites, poor
understanding of how to create support for an energy efficiency project, limited finances
and financial data, poor accountability for measures and perceived risk from changing the
status quo. In addition, business metrics such as energy performance indicators that relate
energy use to production output are typically not utilized, thus making it difficult to
document improvements in energy performance.
Companies who have voluntarily adopted an energy management plan have achieved
major energy intensity improvements. Some examples include:
• Dow Chemical achieved 22% improvement ($4B savings) between 1994 and
2005, and is now seeking another 25% from 2005 to 2015
• United Technologies Corporation reduced global GHG emissions by 46% per
revenue dollar from 2001 to 2006,: an additional 12% reduction is sought from
2006 to 2010
• Toyota’s North American (NA) Energy Management Organization has reduced
energy use per unit by 23% since 2002; company-wide energy efficiency
improvements have saved $9.2 million in NA since 1999.
• InterfaceFLOR, a carpet manufacturer, is a world leader in sustainable
manufacturing and has reduced its energy intensity for manufactured carpet by
35% from 1994 to 2004 through a systematic continual improvement program in
energy efficiency.
Denmark, Sweden, Ireland, Korea, Spain, Thailand, and the U.S. have a national
energy management standard. Japan has a legal requirement for its more energy intensive
industrial facilities to have an energy manager and an energy management plan. These
requirements also extend to large commercial facilities and parts of the transportation
sector. The Netherlands has an energy management specification closely linked to long-
term agreements. The European Committee for Standardization (CEN) and the European
Committee for Electrotechnical Standardization (CENELEC) have developed a common
standard for the European Union, to be published in mid-2009. China also has a draft
national energy management standard expected to be published in 2009.
4
Table 1 compares the elements of the energy management standards in seven
countries or regions with existing energy management standards (or specifications) plus
two under development and Japan (energy management required by legislation). In all
instances, the standard has been developed to be entirely compatible with the ISO quality
(ISO 9001:2008) and environmental (ISO 14001:2004) management standards. A number
of countries have enabling programs, such as target-setting agreements and/or tax policies,
which drive the use of their national energy management standard. The importance of
enabling programs to accelerate uptake of the standard cannot be overstated. As indicated
in Table 1, market penetration of the US energy management standard is less than 5%,
although it has been in place since 2000. This can be largely attributed to the lack of
enabling programs and policies. The first such program, Superior Energy Performance,
is now in its pilot phase.
While the existing energy management standards and specifications have many
features in common, they have subtle variations in language, content, and approach. The
continued proliferation of national and regional energy management activities in a market
that is increasingly global in scope creates the need for an international approach. ISO
now identifies energy management as one of its the top five priorities based on its
enormous potential to save energy, increase profitability, and reduce greenhouse gas
(GHG) emissions worldwide.1
A successful program in energy management begins with a strong commitment to
continual improvement of energy efficiency. A first step once the organizational structure
(management representative and cross-divisional/functional team) has been established
involves assessing the major energy uses in the facility to develop a baseline of energy
use and set targets for improvement. The selection of energy performance indicators and
objectives help to shape the development and implementation of an action plan. The
effectiveness of an action plan depends on the involvement of personnel throughout the
organization, who need to be aware of energy use and performance objectives. Staff and
those who work on behalf of the organization need training in both skills and day-to-day
practices to improve energy performance. The results should be regularly evaluated and
communicated to all personnel, recognizing high achievement. The emergence over the
past decade of better integrated and more robust control systems can play an important
role in energy management and in reducing energy use. 2
Experience in countries with energy management standards has shown that the
appropriate application of these standards requires significant training and skill.
Implementation of an energy management standard within an organization requires a
change in existing institutional practices toward energy, a process that may benefit from
technical assistance from experts outside the organization. There is a need to build not
only internal capacity within the organizations seeking to apply the standard, but also
external capacity from knowledgeable experts to help establish an effective
implementation structure.

Supporting the Transition to Energy Management in Industry
The core of any energy management standard involves the development of an
energy management system. For organizations already familiar other management
systems, such as ISO 90001 (quality) and ISO 14001 (environmental), implementation of
a management system for energy includes many similar elements. For these organizations,
the need for outside assistance may be limited to an orientation period and initial
coaching, especially in some of the more technical aspects of managing energy data and
measuring performance. For organizations without such experience, varying degrees of
technical support will likely be required for several years until the energy management
plan is well-established.
The suite of skills required to provide the technical assistance needed for energy
management is unique, since it combines both management systems and energy
efficiency. Individuals and firms familiar with management systems, for example -
quality, safety, and environment, understand the dynamics of establishing a management
system and its successful integration into the organization’s corporate culture. These
experts, however, typically have little or no expertise in energy efficiency. In contrast,
industrial energy-efficiency experts are highly specialized in energy efficiency, but are
trained and oriented toward the identification and execution of energy-efficiency projects
without a management system context. Globally, the need for energy management
experts is expected to increase exponentially once ISO 50001 is published in early 2011.
Capacity-building is urgently needed now to meet this growing need.
Several countries have initiated training and support activities in an effort to
create both internal capacity within implementing organizations as well as external
capacity by creating a cadre of experts in energy management. For building internal
capacity, SenterNovem in the Netherlands and the Carbon Trust in the UK offer a series
of web-based tools to assist industrial facilities seeking to initiate an energy management
plan. Ireland and Sweden both offer industrial facilities training in energy management;
the Irish also have tools such as the Energy MAP3. In the U.S., the Georgia Institute of
Technology has an extensive training program for industrial facilities implementing the
U.S. national energy management standard; this program is currently being modified to
allow industrial facilities to access tools and training remotely, as well as in a classroom.
A well-developed program for both internal and external capacity-building for
energy management already exists in Japan. An extensive series of training courses are
offered to prepare for a qualifying exam to become licensed as a Qualified Person in
Energy Management. Demand for the course is driven by a legislative requirement for
five energy-intensive industries to appoint a Registered Energy Manager or a qualified
person for energy management. For many other industries, there is a requirement to
appoint a qualified person for energy management. 4
A program to certify individuals for energy management via a professional
certification program is also part of the U.S. energy efficient manufacturing initiative,
Superior Energy Performance. This initiative is developing an American National
Standards Institute (ANSI) -accredited certification of industrial plants based on

conformance with ISO 50001 and improved energy performance.5 It is anticipated that
the Certified Practitioners will draw potential candidates from both energy efficiency and
management system backgrounds. Candidates must demonstrate experience in
management systems and will be subject to a rigorous qualification exam, certified by an
independent third party organization and, once certified, be subject to periodic
professional enrichment requirements.
The United Nations Industrial Development Organization (UNIDO) is continuing
its interest and support for energy management through the inclusion of capacity-building
as part of its regional and national programs in a number of countries in Southeast Asia,
plus South Africa, Russia, and Turkey. Since system optimization is not taught in
universities or technical colleges, these programs also include capacity-building for
system optimization, based on a successful model developed for a pilot program in
China.
Role of Emerging Economies and Developing Countries
While the industrial sector represents more than one third of both global primary
energy use and energy-related carbon dioxide emissions (Price et al., 2006), it is
frequently in excess of 50% in emerging economies and developing countries and can
lead to conflicts with constraints on energy supply. Further, countries with an emerging
and rapidly expanding industrial infrastructure have a particular opportunity to increase
their competitiveness by applying energy-efficient best practices from the outset in new
industrial facilities. For example, 80% of global industrial growth in over the past ten
years has been in China (IEA 2007). Integrating energy efficiency into the initial design
or substantial redesign is typically less expensive and allows for better overall results
than retrofitting existing industrial facilities. Conversely, failure to integrate energy
efficiency in new industrial facility design in emerging economies and developing
countries represents a large and permanent loss in climate change mitigation potential
that will persist for decades until these facilities are scheduled for major renovation. The
current economic downturn provides a unique opportunity for industry, particularly
rapidly growing industries in developing countries, to regroup and embed energy
management practices in anticipation of the next cycle of economic growth.
UNIDO recognized the industry’s need to enhance competitiveness while
responding effectively to climate change and to the proliferation of national energy
management standards. In March 2007, UNIDO hosted a meeting of experts from
developing countries and emerging economies, nations that had adopted or were
developing national energy management standards and representatives from the ISO
Central Secretariat. That meeting led to submission of a formal recommendation to the
ISO Central Secretariat to consider undertaking work on an international energy
management standard.
UNIDO has been supporting the development process of ISO 50001 by
facilitating the participation of developing countries and emerging economies in the
process through international and regional workshops, and a survey on energy
management in industry.

A key objective of the UNIDO survey is to better understand the potential
opportunities, barriers and challenges for industry in adopting and implementing energy
management standards. In partnership with the Standards, Productivity and Innovation
Board (SPRING) and the National Environment Agency (NEA) of Singapore, UNIDO
piloted the survey in July 2008.
The Survey was sent to 47
enterprises of six different sectors,
with 27 enterprises completing and
returning the survey. Table 2
shows the sectors and distribution
of respondents by company size.
Below is a summary of the results.
The catalytic role of ISO9000/ISO14000
The majority of enterprises using management system standards such as ISO 9001
and ISO 14001 have some elements of an energy management system in place. Most of
these ISO certified organizations have an energy policy (Fig 1) and most organizations
with such a policy have energy efficiency and performance goals (Fig 2) and
management- appointed responsible persons. However, at the level of implementation
and performance/management review, signs of inconsistency and weak methodologies
appear together with limited use of systemic approaches (Figs 3 and 4).
The information and technical capacity gap challenge
As previously mentioned, experience with national energy management standards
has demonstrated that the adoption of voluntary standards is heavily dependent on the
existence of supporting programs and incentives. Responses to the pilot survey appear to
reinforce the need for articulated programs targeted to intervene at all levels of the energy

management decision-making, development, financing, and implementation process. The
lack of information at the plant level remains a key barrier to improved energy
management and energy efficiency in industry. This sample indicates a high level of
interest in access to expert networks, sector-specific energy efficiency expertise, and
technical tools (Figs 5 and 6). Energy benchmarks are seen as highly useful, yet remain
largely unavailable (Fig 7).
Scoring legend: 1 = Not useful 2 = Quite useful 3 = Useful 4 = Very useful
While the small sample of respondent enterprises (27 out of 47) does not allow
extrapolation of results to Singapore industry as a whole, the data has provided useful
insight and hints for further analysis. The survey is currently being replicated in
Brazilian enterprises in collaboration with the Brazilian National Confederation of
Industry and will be implemented in a modified form in Southeast Asia. It is important to
note that Singaporean industries are better aligned with developed, rather than developing
economies relative to the integration of energy management into business practices. It is
reasonable to assume that the need for access to energy efficiency information and skills
will be even greater in developing countries
Framework for success
A successful program in energy management provides an organizational
framework for a company to respond effectively through a program of continuous
improvement to a national program that establishes energy intensity improvement and/or
GHG reduction targets. UNIDO has identified a package of policies described as the
“Industrial Standards Framework” that outlines the policy relationships among target-
setting agreements, energy management standards, and system optimization and their
intended impact on industrial markets.

Table 2 Industrial Standards Framework
UNIDO is currently engaged with 10 countries in the development of industrial energy
efficiency programs based on the framework described above.
Developing ISO 50001: Energy Management
In February 2008, the Technical Management Board of ISO approved the
establishment of a new project committee (PC 242 – Energy Management) to develop the
new ISO Management System Standard for Energy.6
ANSI and the Associação Brasileira de Normas Técnicas (ABNT) jointly serve as
the Secretariat to PC 242 to lead development of ISO 50001. This standard will establish
an international framework for industrial, commercial, or institutional facilities, or entire
companies, to manage their energy, including procurement and use. The standard will
provide organizations and companies with technical and management strategies to
increase energy efficiency, reduce costs, and improve environmental performance.
Corporations, supply chain partnerships, utilities, energy service companies, and others
are expected to use ISO 50001 as a tool to reduce energy intensity and carbon emissions
in their own facilities (as well as those belonging to their customers or suppliers) and to
benchmark their achievements.
To foster development of the standard, UNIDO and the Standardization
Administration of China (SAC) jointly hosted an international meeting in Beijing in April
6 http://www.iso.org/iso/energy_management_system_standard
11
2008 to initiate a dialogue on harmonization of national and regional standards in
preparation for the first meeting of ISO PC 242.
The first meeting of ISO PC 242 was held in September 2008 in Washington, DC
with participation by delegates from 25 countries from all regions of the world, as well as
representation from UNIDO, which has liaison status. The goal of ISO PC 242 is to
develop the new management system ISO 50001 on an accelerated schedule. Between
the first meeting in September and the second meeting in March 2009 in Rio de Janeiro,
Brazil, ISO PC 242 produced two working drafts for expert review and comment by
member countries (35 as of March 2009). At the March meeting, a decision was made to
go to Committee Draft (CD) in June 2009, following additional expert review and input.
This puts development of ISO 50001 on track for publication in early 2011.
Some of the major issues being addressed by ISO PC 242 include:
• The definition of energy and energy performance, with the term “energy
performance” encompassing energy efficiency, energy conservation, and
increased use of renewable energy, as determined by the implementing
organization in their policy, targets, and objectives;
• The role of top management in setting policy and empowering staff to implement
it;
• The term “team” as applied to persons responsible for carrying out the energy
management policy. Team describes the personnel resources necessary to
implement and maintain the action plans and objectives of the organization and
could be one person;
• An approach for energy planning that focuses on the process an organization
would use both to implement and to maintain their management system;
• The appropriate role of purchasing for energy efficient supply, equipment,
products, and services in a globally relevant standard;
• The role of renewable energy in energy management and energy performance,
and
• The need for an annex that helps small and mid-size organization.
Potential Impact
Existing ISO standards for quality management practices (ISO 9001) and
environmental management systems (ISO 14001) have successfully stimulated
substantial, continual efficiency improvements around the globe. The emergence of ISO
50001, the international energy management standard is anticipated to have far-reaching
effects on the energy efficiency of industry when it is published in early 2011.
This will be especially true in developing countries and emerging economies that
still lack national energy management standards as well as policies and mechanisms to
achieve improved efficiency in the industrial sector. Past experience with environmental
management standards shows that the ISO standards have provided stimulus and a
framework for the development of national standards, policies, laws and regulation. In
addition, all indications are that ISO 50001 will become a significant factor in
international trade, as ISO 9001 has been.
12
ISO 50001 has the potential to impact 60% of the world’s energy use, including
not only industry, but also the commercial and institutional sectors. Based on
demonstrated savings that have been achieved by organizations that have implemented
energy management plans and a continual improvement framework, energy intensity
improvements of greater than 2.5% per year are achievable and can be sustained for the
next decade. The International Energy Agency has stated that
(the) manufacturing industry can improve its energy efficiency by an impressive 18 to 26%, while
reducing the sector’s CO2 emissions by 19 to 32%, based on proven technology. Identified
improvement options can contribute7 to 12% reduction in global energy and process-related CO2
emissions (IEA 2007).
.
The emergence of ISO 50001 will be an important link in realizing these impacts.
