To live a life of sufficiency in a consumerist culture may be one of the most ambitious experiments an individual could undertake. To investigate this challenge, we employed a social-practice approach. This article is based on 42 qualitative interviews asking respondents why and how they acted in a sufficient way within a Western infrastructure and culture. The results indicate that sufficiency-oriented people draw on particular meanings in everyday-life practices when adopting relevant resource-extensive actions. These understandings encompass an amalgam of environmentally friendly attitudes, positive social intentions, and/or personal commitments to thriftiness. We further identified a set of specific practices - including sharing, recycling, and reusing - as useful for the adoption of a sufficient lifestyle. For our respondents, many of these sufficiency practices occurred regularly in daily life and were rarely questioned. Using an additional survey, we show that these routines lead to less resource-intensive lifestyles and demonstrate how a small group of people has been able to habitually adopt sufficiency practices. However, the majority does not see a need for more frequent implementation of such routines because daily decision-making processes are widely focused on the consumption of products.
On 12 December 2015, the Parties to the UNFCCC adopted the "Paris Agreement". With this step, the world community has agreed on a collective and cooperative path to fight human-induced climate change: After 25 years of UN climate diplomacy, the world's governments have for the first time in history negotiated a treaty which envisages climate action by all nations. The Agreement sets the world on a path that might lead to a decarbonised economy in the second half of the century. Researchers from the Wuppertal Institute have observed COP 21 and elaborated a detailed analysis of the results. The assessment provides an overview of the most important negotiation outcomes, assesses their results as well as shortfalls and provides an outlook of the next steps needed to implement the Paris Agreement's goals and to set the world firmly on a non-fossil based development path.
The German government has set itself the target of reducing the country's GHG emissions by between 80 and 95% by 2050 compared to 1990 levels. Alongside energy efficiency, renewable energy sources are set to play the main role in this transition. However, the large-scale deployment of renewable energies is expected to cause increased demand for critical mineral resources. The aim of this article is therefore to determine whether the transformation of the German energy system by 2050 ("Energiewende") may possibly be restricted by a lack of critical minerals, focusing primarily on the power sector (generating, transporting and storing electricity from renewable sources). For the relevant technologies, we create roadmaps describing a number of conceivable quantitative market developments in Germany. Estimating the current and future specific material demand of the options selected and projecting them along a range of long-term energy scenarios allows us to assess potential medium- or long-term mineral resource restrictions. The main conclusion we draw is that the shift towards an energy system based on renewable sources that is currently being pursued is principally compatible with the geological availability and supply of mineral resources. In fact, we identified certain sub-technologies as being critical with regard to potential supply risks, owing to dependencies on a small number of supplier countries and competing uses. These sub-technologies are certain wind power plants requiring neodymium and dysprosium, thin-film CIGS photovoltaic cells using indium and selenium, and large-scale redox flow batteries using vanadium. However, non-critical alternatives to these technologies do indeed exist. The likelihood of supplies being restricted can be decreased further by cooperating even more closely with companies in the supplier countries and their governments, and by establishing greater resource efficiency and recyclability as key elements of technology development.
Limiting global warming to below 2 °C or even 1.5 °C requires a fundamental transformation of global socio-economic systems. This need for transformation has been taken up by international climate policy. This article synthesizes criteria of transformational change from transition research and climate finance agencies. On this basis, the article conducts a multi-criteria evaluation of the transformative potential of the European Union Emissions Trading Scheme (EU ETS), currently the world's largest market-based climate policy. From this case it can be inferred that emissions trading can "destabilize" incumbent high-emission practices, but its effectiveness in fostering innovation is limited. Furthermore, the analysis shows that details in the arrangements of the scheme such as allocation rules can have a strong detrimental impact on its outcome. If a global carbon market with a uniform price were introduced, this could lead to developing countries "buying in" with large amounts of freely allocated allowances. This, however, has been shown to thwart transformational effects and instead contribute to further carbon lock-in.
The German federal state of North Rhine-Westphalia (NRW) is home to one of the most important industrial regions in Europe, and is the first German state to have adopted its own Climate Protection Law (CPL). This paper describes the long-term (up to 2050) mitigation scenarios for NRW’s main energy-intensive industrial sub-sectors which served to support the implementation of the CPL. It also describes the process of scenario development, as these scenarios were developed through stakeholder participation. The scenarios considered three different pathways (best-available technologies, break-through technologies, and CO2 capture and storage). All pathways had optimistic assumptions on the rate of industrial growth and availability of low-carbon electricity. We find that a policy of "re-industrialisation" for NRW based on the current industrial structures (assumed here to represent an average growth of NRWs industrial gross value added (GVA) of 1.6% per year until 2030 and 0.6% per year from 2030 to 2050), would pose a significant challenge for the achievement of overall energy demand and German greenhouse gas (GHG) emission targets, in particular as remaining efficiency potentials in NRW are limited. In the best-available technology (BAT) scenario CO2 emission reductions of only 16% are achieved, whereas the low carbon (LC) and the carbon capture and storage (CCS) scenario achieve 50% and 79% reduction respectively. Our results indicate the importance of successful development and implementation of a decarbonised electricity supply and breakthrough technologies in industry - such as electrification, hydrogen-based processes for steel, alternative cements or CCS - if significant growth is to be achieved in combination with climate mitigation. They, however, also show that technological solutions alone, together with unmitigated growth in consumption of material goods, could be insufficient to meet GHG reduction targets in industry.
This article presents an integrated assessment conducted in order to explore whether carbon capture and storage (CCS) could be a viable technological option for significantly reducing future CO2 emissions in South Africa. The methodological approach covers a commercial availability analysis, an analysis of the long-term usable CO2 storage potential (based on storage capacity assessment, energy scenario analysis and source-sink matching), an economic and ecological assessment and a stakeholder analysis. The findings show, that a reliable storage capacity assessment is needed, since only rough figures concerning the effective capacity currently exist. Further constraints on the fast deployment of CCS may be the delayed commercial availability of CCS, significant barriers to increasing the economic viability of CCS, an expected net maximum reduction rate of the power plant's greenhouse gas emissions of 67%-72%, an increase in other environmental and social impacts, and low public awareness of CCS. One precondition for opting for CCS would be to find robust solutions to these constraints, taking into account that CCS could potentially conflict with other important policy objectives, such as affordable electricity rates to give the whole population access to electricity.
Dieser Beitrag beschäftigt sich mit den strukturkonservierenden Regime-Elementen der deutschen Energieversorgung. Methodisch wird dabei der Transitionsansatz von Geels genutzt. Mithilfe der Multi-Level-Perspektive wird am Beispiel der örtlichen Stromverteilnetze gezeigt: Innovationen finden in Nischen statt und müssen die Hemmnisse und das Beharrungsvermögen des nuklear-fossilen Altregimes überwinden, Anhand empirischer Analysen wird gezeigt, dass die Widerstandsfähigkeit sowie die kollektive Marktmacht des etablierten Regimes auf der Stromverteilnetzebene die zur Transformation der Energiewirtschaft erforderliche Dezentralisierung entscheidend ausbremst. Auf der anderen Seite wird dargelegt, dass Stadtwerke als örtliche Verteilnetzbetreiber wichtige Schlüsselakteure der deutschen Energiewende sind und zahlreiche Voraussetzungen erfüllen, einen grundlegenden Strukturwandel voranzutreiben. Der Trend zur Rekommunalisierung und zur Neugründung von Stadtwerken belegt dabei den Wunsch einer Verstärkung kommunalpolitischer Gestaltungsmöglichkeiten. In diesem Kontext werden Zielvorstellungen formuliert und auf erfolgversprechende Strategien zur Veränderung des Altregimes eingegangen.
Technologischer Wandel ist wichtig für die Umsetzung und den Erfolg der Energiewende, deswegen strebt die Bundesregierung mit ihrer Politik auch eine positive Innovationswirkung an. Doch welche Auswirkungen hat der politisch angestoßene Wandel des Energiesystems wirklich und welche Dynamiken werden durch ihn induziert? Eine aktuelle Studie untersucht die Sicht auf die Energiepolitik und Innovationsaktivitäten in der Energiewirtschaft und Energietechnologie-Branche. Sie zeigt die durch die Energiewende getriebenen Innovationsdynamiken, aber auch Schwierigkeiten und Herausforderungen für Politik und Unternehmen auf.
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.
Achieving a truly sustainable energy transition requires progress across multiple dimensions beyond climate change mitigation goals. This article reviews and synthesizes results from disparate strands of literature on the coeffects of mitigation to inform climate policy choices at different governance levels. The literature documents many potential cobenefits of mitigation for nonclimate objectives, such as human health and energy security, but little is known about their overall welfare implications. Integrated model studies highlight that climate policies as part of well-designed policy packages reduce the overall cost of achieving multiple sustainability objectives. The incommensurability and uncertainties around the quantification of coeffects become, however, increasingly pervasive the more the perspective shifts from sectoral and local to economy wide and global, the more objectives are analyzed, and the more the results are expressed in economic rather than nonmonetary terms. Different strings of evidence highlight the role and importance of energy efficiency for realizing synergies across multiple sustainability objectives.
