The efficiency strategy to exploit the potential for energy savings in buildings still is applied rather slowly in most countries. In addition, there are indications that energy savings are partly compensated particularly by wealth but also rebound effects, the "empty nest" (persistence of elderly people and couples in family homes), and cohort effects (e.g. vintages of people or buildings). In Germany, as in other European countries, the existing trend in housing is a continuously growing floor space per capita. Over the last decades it expanded from about 20 m2 in 1960 to currently 45 m2 per person. Forecasts expect a further increase to more than 50 m2 per person. Obviously, more floor space needs more energy for space heating and cooling, ventilation, and lighting, but it also allows the household to operate more and or bigger appliances, all of which increase energy consumption.
On the other hand, housing projects emerge offering relatively small private living spaces in combination with various shared spaces to use. Many of them are based on private initiatives. But what is the motivation behind it? And is there a higher need for new living concepts in the future?
The proposed paper presents main drivers of increasing floor space per capita in Germany and discusses the question if more space is necessary for higher comfort. It presents different examples of housing concepts that strive to achieve good living with less space and suggests a "building typology of sufficiency".
Finally, the paper discusses qualitatively to which extent these housing concepts can lead to less energy use and emissions. In this way sufficiency could be best friend with efficiency and tackle wealth, rebound, and other effects that counter-act efficiency progress. But therefore, as the paper concludes, politics and policies should recognise sufficiency as a field of action instead of referring to individual decisions and lifestyles.
Das Deutsche Zentrum für Luft- und Raumfahrt (DLR) hat gemeinsam mit dem Wuppertal Institut für Klima, Umwelt, Energie in der Studie "STROMbegleitung" Technologien, Perspektiven und Ökobilanzen elektrifizierter PKW untersucht. Die Studie gibt einen umfassenden Einblick in den aktuellen Stand der Technik, identifiziert Trends und analysiert die Ökobilanz unterschiedlicher Fahrzeugkonzepte. Gleichzeitig ordnet sie die deutschen Aktivitäten im Bereich Elektromobilität in einen globalen Kontext ein.
German electricity giants have recently taken high-level decisions to remove selected fossil fuel operations from their company portfolio. This new corporate strategy could be seen as a direct response to the growing global influence of the fossil fuel divestment campaign. In this paper we ask whether the divestment movement currently exerts significant influence on decision-making at the top four German energy giants - E.On, RWE, Vattenfall and EnBW. We find that this is not yet the case. After describing the trajectory of the global fossil fuel divestment campaign, we outline four alternative influences on corporate strategy that, currently, are having a greater impact than the divestment movement on Germany's power sector. In time, however, clear political decisions and strong civil support may increase the significance of climate change concerns in the strategic management of the German electricity giants.
Decision-making in sustainable urban mobility planning : common practice and future directions
(2015)
The European Commission aims to foster sustainable local transport systems through the concept of "Sustainable Urban Mobility Plans" (SUMPs). This paper is intended as a think piece highlighting the challenges for cities in selecting sustainable and cost-effective transport and mobility measures. Not only does the paper convey an understanding of the challenges of determining a transport project's viability, but it also presents five case studies of sustainable urban mobility planning and the role of project appraisal in those policy-making processes.
Decoupling resource consumption and economic growth : insights into an unsolved global challenge
(2015)
Parties to the United Nations Framework Convention on Climate Change (UNFCCC) have decided to establish a "new market-based mechanism" (NMM) to promote mitigation across "broad segments" of developing countries' economies but have so far defined only some broad outlines of how it is to function. This article identifies key design options of the NMM based on a survey of the literature and reviews them against a range of assessment criteria. Furthermore, potential application of the NMM is analysed for five country-sector combinations. The analysis finds that lack of data and of institutions that could manage the NMM are key bottlenecks. In addition, the analysis reveals the existence of substantial no-regret reduction potential, suggesting that sectors may not be sensitive to the market incentives from an NMM. Governmental capacity building and Nationally Appropriate Mitigation Actions (NAMAs) might be more appropriate in the short term, preparing the ground for the adoption of market-based approaches at a later stage. NMM pilots could be based on supported NAMAs but should ideally generate tradable and compliance-grade emission credits in order to fully simulate the real-life conditions of an NMM.
Policy relevance: The Doha conference identified "possible elements" of the NMM to be addressed in the development of the NMM's modalities and procedures. This article identifies available options for these possible elements and reviews these options against a number of criteria, including environmental effectiveness, economic efficiency, political and administrative efficiency, and others. On this basis the article identifies options that are best suited to fulfil the main aims of the NMM as decided at the Durban conference, "to enhance the cost-effectiveness of, and to promote, mitigation actions". In addition, the article analysis potential application of the NMM for five country-sector combinations. The analysis assesses the emission reduction potential that could be mobilized through the NMM as well as the institutional market readiness of the sectors. Finally, the article synthesizes the challenges ahead for the NMM that have emerged from the analysis and suggests possible ways forward.
