Supplementary Material to "Feasibility of sufficiency-policy instruments: an assessment using impact chains for the German mobility sector", https://doi.org/10.1080/15487733.2024.2446079

The transport sector is not on track to meet the Paris Agreement climate targets. Rapid decarbonization of transport requires fuel switching and energy savings through modal shift and demand reduction-which are the aims of transport-sufficiency policy. We analyze passenger transport-policy instruments collected in the European Sufficiency Policy Da...

A reduction of energy service demand in all sectors is required to reach ambitious climate and other sustainability goals. A growing number of energy and climate scenarios does include detailed assumptions and quantified parameters for the reduction of energy service demand. However, the indicators and units used to measure the demand reduction pot...

A detailed assessment of a low energy demand, 1.5 ∘C compatible pathway is provided for Europe from a bottom-up, country scale modelling perspective. The level of detail enables a clear representation of the potential of sufficiency measures. Results show that by 2050, 50% final energy demand reduction compared to 2019 is possible in Europe, with a...

Businesses want to be sustainable but how can they promote sufficiency? Sufficiency-oriented business models focus on creating sustainable value, promoting reduced resource consumption and adjusting production volumes to planetary boundaries. The contributors to this volume present real-life examples of sufficiency-oriented companies across diverse...

The authors are all devoted energy system and sustainability transformation scholars, who collaborate regularly and actively at global and local levels to advance the knowledge space of demand-side solutions and policies. They are members of a growing bottom-up initiative, the Energy Demand Changes Induced by Technological and Social Innovations (E...

There is a growing body of scientific evidence supporting sufficiency as an inevitable strategy for mitigating climate change. Despite this, sufficiency plays a minor role in existing climate and energy policies. Following previous work on the National Energy and Climate Plans of EU countries, we conduct a similar content analysis of the recommenda...

Impact chains are used in many different fields of research to depict the various impacts of an activity and to visualize the system in which this activity is embedded. Research has not yet conceptualized impact chains specifically for energy sufficiency policies. We develop such a concept based on current evaluation approaches and extend these by...

Sufficiency measures are potentially decisive for the decarbonisation of energy systems but rarely considered in energy policy and modelling. Just as efficiency and renewable energies, the diffusion of demand-side solutions to climate change also relies on policy-making. Our extensive literature review of European and national sufficiency policies...

Sufficiency as a term and research field has gained increased attention in recent years. The evolving literature demonstrates various understandings of sufficiency: thought from the concept of consumption corridors, it is a way to mitigate climate change but it also is a more general approach to reach various dimensions of ecological and socio-econ...

Gegenstand dieser Evaluierung war die Mini-KWK-Richtlinie, die am 1.01.2015 in Kraft trat. Betrach-tet wurden die Förderaktivitäten (Auszahlung des Investitionszuschusses) in den Kalenderjahren 2018 und 2019. Die NKI unterstützt durch diese Richtlinie den Einbau von Mini-KWK-Anlagen bis zu einer Leistung von 20 kWel in Bestandsbauten mit einem Inv...

Energy sufficiency is one of the three energy sustainability strategies, next to energy efficiency and renewable energies. We analyse to what extent European governments follow this strategy, by conducting a systematic document analysis of all available European National Energy and Climate Plans (NECPs) and Long-Term Strategies (LTSs). We collect a...

On the pathway to climate neutrality, EU member states are obliged to submit national energy and climate plans (NECPs) with planned policies and measures for decarbonization until 2030 and long-term strategies (LTSs) for further decarboniza-tion until 2050. We analysed the 27 NECPs and 15 LTSs submitted by October 2020 using an inter-rater method....

Klimaschutzkonzepte und -szenarien fokussieren in der Regel auf Politikinstrumente und Maßnahmen, die entweder die Effizienz von Geräten, Anlagen, Gebäuden und Prozessen steigern sollen oder den Ausbau und die Integration erneuerbarer Energien zum Thema haben. Obwohl Suffizienzmaßnahmen wichtige Potenziale haben (vgl. Fischer et al. 2016), sind sie...

The European Union has committed to 2030 targets: cutting greenhouse gases by 40 % compared to 1990, decreasing energy consumption by 32.5 % compared to a baseline scenario, and to increase the share of renewable energy to at least 32 % of gross final energy consumption. Energy efficiency first is the key principle of this climate and energy strat...

The German National Climate Initiative (NCI) presents one cornerstone of the German Government's ambitious plans to reduce GHG emissions. It was initiated in 2008 to contribute to the German climate targets and addresses businesses, consumers and local authorities in areas with significant efficiency and mitigation potentials that cannot be tapped...

The German National Climate Initiative (NCI) is a cornerstone of the German Government's ambitious plans to reduce GHG emissions. It was initiated in 2008 to contribute to the German climate targets. The NCI aims to change behavior and stimulate investment towards lower GHG emissions by bringing together different actors, taking local initiative, r...

Es gibt mehrere Wege zum Klimaschutz. Mit einigen davon, wie etwa Effizienzprogrammen unddem Ausbau erneuerbarer Energien sind wir relativ vertraut. Diese Studie betrachtet mitSuffizienzstrategien einen dritten Weg, der ebenfalls ein hohes Potenzial besitzt, zumKlimaschutz beizutragen. Der Fokus der Studie liegt dabei auf der Modellierung von Suffi...

Dieses Papier lädt zu einem Gedankenexperiment ein: Stellen wir uns vor, wir schaffen es, bis 2050 den Ausstoß von Treibhausgasen in Deutschland um 95 % gegenüber 1990 zu verringern. Das heißt, wir stellen uns auch vor, dass Deutschland einen angemessenen Beitrag zum Zwei-Grad-Limit leistet: Dieses Limit ist die von der internationalen Gemeinschaft...

Reducing greenhouse gas emissions to limit global warming to well below 2°C or even to 1.5°C, as emphasised by world leaders in the Paris Agreement reached in December 2015, can only succeed if deforestation is cut dramatically in the next decades because the resulting emissions nearly make up one fifth of all greenhouse gas emissions worldwide. M...

The objective of this study is to provide technical assistance in the preparation of the 2016 Report on Renewable Energy, in preparation of the Renewable Energy Package for the period 2020-2030 in the European Union. Key findings are: Renewable energy sources (RES) are deployed by all EU Member States in the electricity, heating & cooling and tran...
