The Global Stocktake (GST) takes a central role within the architecture of the Paris Agreement, with many hoping that it will become a catalyst for increased mitigation ambition. This paper outlines four governance functions for an ideal GST: pacemaker, ensurer of accountability, driver of ambition and provider of guidance and signal. The GST can set the pace of progress by stimulating and synchronizing policy processes across governance levels. It can ensure accountability of Parties through transparency and public information sharing. Ambition can be enhanced through benchmarks for action and transformative learning. By reiterating and refining the long term visions, it can echo and amplify the guidance and signal provided by the Paris Agreement. The paper further outlines preconditions for the effective performance of these functions. Process-related conditions include: a public appraisal of inputs; a facilitative format that can develop specific recommendations; high-level endorsement to amplify the message and effectively inform national climate policy agendas; and an appropriate schedule, especially with respect to the transparency framework. Underlying information provided by Parties complemented with other (scientific) sources needs to enable benchmark setting for collective climate action, to allow for transparent assessments of the state of emissions and progress of a low-carbon transformation. The information also needs to be politically relevant and concrete enough to trigger enhancement of ambition. We conclude that meeting these conditions would enable an ideal GST and maximize its catalytic effect.
"400,000 new homes per year are needed in German cities." This figure has been cited repeatedly in political discussions, media, and statements of different groups for a couple of years now. Living space is needed to mitigate the (further) inordinate increase of rents in some cities and regions and to ease finding appropriate flats at affordable prices for low- and medium-income households. But how to activate investors and the real estate market?
Having the triangle of sustainability in mind with its ecologic, social and economic cornerstones the discussion - metaphorically spoken - currently pulls the three corners: Which should have the highest priority?
The economically driven most favourable solution is lowering the requirements for new buildings such as the energy performance to make building cheaper. The social perspective prefers an increase of public social housing investments regardless of efficiency standards. And the ecological side argues that a high performance is needed to reach energy and climate targets in the buildings sector.
Starting at this point of discussion, firstly, the paper reflects the assumptions behind the numbers of new homes needed against a sufficiency background.
Secondly, it presents current changes in German building policies: a new legislation for energy supply and efficiency is currently in preparation.
It discusses the potential to integrate sufficiency aspects in building policies, focussing specifically on the new regulation, financial incentives, and energy advice.
The paper analyses if and to what extent it is likely to balance the three cornerstones of sustainability by integrating sufficiency aspects into efficiency policies. Household experiences with prepayment meters are used as an example to illustrate the potential for tapping efficiency and sufficiency potentials in low-income households considering social, economic, and ecological aspects. Based on the identified (in)consistencies, thirdly, it suggests further development in German policies to make better use of synergies between the ecologic, social and economic demands on buildings.
Der NaWis-Verbund verstärkt seine Bestrebungen, die gesellschaftlichen Wirkungen von transformativer Forschung abzubilden. Damit soll auch die Qualität der Forschungsarbeiten gesichert werden. Die bei der Impact-Messung zur Anwendung kommenden Ansätze unterscheiden sich bislang grundsätzlich. Der vorliegende Beitrag skizziert den Zugang des Wuppertal Instituts für Klima, Umwelt, Energie.
Footprint calculators are efficient tools to monitor the environmental impact of private consumption. We present the results of an analysis of data entered into an online Material Footprint calculator undertaken to identify the socioeconomic drivers of the Material Footprint in different areas of consumption, from housing to holidaymaking. We developed regression models to reveal (1) the impact of socioeconomic characteristics on Material Footprints of private households and (2) correlations between the components of Material Footprints for different arrays of consumption. Our results show that an increasing Material Footprint in one array of consumption comes with an increasing Material Footprint in all other arrays, with the exception of housing and holidaymaking. The socioeconomic characteristics of users have a significant impact on their Material Footprints. However, this impact varies by the array of consumption. Households only exhibit generally bigger Material Footprints as a result of higher incomes and larger dwellings. We conclude that indicators which strive to monitor resource efficiency should survey disaggregated data in order to classify the resource use to different population groups and arrays of consumption.
How can existing national climate policy instruments contribute to ETS development? : Final report
(2019)
Before introducing an emissions trading system, jurisdictions have to consider the ex-isting energy and climate policy framework. This report seeks to analyse and evaluate non-ETS climate policy instruments, such as carbon taxes or green certificate trading schemes, regarding their suitability to serve as a basis for establishing emission trading systems. There is a general assessment of prototypical policy instruments. Besides, the report contains insights from case studies in India and Mexico. The report is meant to inform ETS development by showing how existing policy instruments could contribute to this process and by illustrating how non-ETS policy instruments could coexist with an emissions trading system, allowing for an effective policy mix.
Green Information Systems in general, and footprint calculators in particular, are promising feedback tools to assist people in adopting sustainable behaviour. Therefore, a Material Footprint model for use in an online footprint calculator was developed by identifying the most important predictors of the Material Footprint of the calculator's users. By means of statistical learning, the analysis revealed that 22 of the 95 predictors identified accounted for 74% of the variance in Material Footprints. Ten predictors out of the 95, mainly from the mobility domain, were capable of showing a prediction accuracy of 61%. The authors conclude that 22 predictors from the areas of mobility, housing and nutrition, as well as sociodemographic information, accurately predict a person's Material Footprint. The short and concise Material Footprint model may help developers and researchers to enhance their information systems with additional items while ensuring the data quality of such applications.

(2019)
The twenty-third Conference of the Parties (COP-23) of the United Nations Framework Convention on Climate Change (UNFCCC) was held in Bonn on 6-17 November 2017, under the presidency of Fiji. COP-23 focused, in particular, on developing rules to implement the 2015 Paris Agreement and on raising ambition for climate protection. Since this was the first "Oceanic" COP, special attention was given to supporting the countries of the Global South in their efforts to reduce emissions, adapt to climate change, and deal with the unavoidable impacts of climate change. This article summarizes the main developments and results of COP-23.
Nach jahrzehntelangen, erfolgreichen Reduktionen der CO2-Emissionen in der Industrie, ist der Trend in den letzten Jahren wieder rückläufig geworden: seit 2014 sind die Emissionen wieder angestiegen (UBA 2019). Um die deutschen Klimaziele zu erreichen ist es daher notwendig, die Anstrengungen zu verstärken und intensiver als in der Vergangenheit Innovationen für den Klimaschutz voranzutreiben: Neue Produkte und Geschäftsmodelle sowie neue Herstellungsverfahren zu entwickeln, mit denen sich Treibhausgasemissionen reduzieren lassen.
Um die deutschen Klimaziele für 2030 einzuhalten, werden hierfür gerade auch (inkrementelle) Effizienzsteigerungen nötig sein - diese werden jedoch nicht ausreichend sein. Innovationen müssen auch einen disruptiven Wandel von Strukturen und Geschäftsmodellen erwirken. Disruptive Innovationen und industrielle Konversionsprozesse bergen jedoch hohe Risiken für die etablierte Industrie. Hier stellt sich also die Frage, wie eine auf Klimaschutz ausgerichtete Innovationspolitik gestaltet werden muss, um einerseits die notwendigen CO2-Einsparungen zu ermöglichen und andererseits die Leistungfähigkeit der deutschen Industrie zu befördern?
Vor diesem Hintergrund widmet sich diese Studie zwei zentralen Fragestellungen: Wie laufen Klimaschutz-Innovationsprozesse ab? Wie können Klimaschutz-Innovationen befördert werden?
Basierend auf einer konzeptionellen Klassifizierung von Klimaschutz-Innovationen, wurden eine Reihe von existierenden Klimaschutz-Innovationen, gerade aus der energieintensiven Industrie analysiert. Vier Fallbeispiele aus verschiedenen Sektoren (Aluminiumherstellung und -verarbeitung, Herstellung neuer Kraftstoffe sowie der Verzinkung) und verschiedenen Innovationstypen werden in der Studie ausführlich beschrieben. Dabei zeigt sich, dass sich Unternehmen nicht nur an aktuellen Rahmenbedingungen orientieren, sondern Innovationen - sowohl inkrementeller wie auch radikaler Natur- im Bereich Klimaschutz auch unter der Annahme dynamischer Entwicklungen von sich verstärkenden Klimaschutzrahmenbedingungen vorantreiben. Darüber hinaus waren an allen untersuchten Fällen auch externe Promotoren unterstützend tätig. Daher wurden die möglichen Rollen von Klimaschutz-Promotoren mit unterschiedlichen regionalen und inhaltlichen Schwerpunkten gezielt analysiert.
Eine sich vorrangig auf technologische Innovationen und Entlastungsgewinne stützende Wirtschafts- und Umweltpolitik wird für die dauerhafte Senkung der Ressourcennutzung nicht ausreichen. Es bedarf auch kultureller Veränderungen im Umgang mit Ressourcen und ambitionierter und wegweisender politischer Maßnahmen.
Last year's conference of the global climate change regime took place from 2 until 15 December 2018 in Katowice, Poland. The conference had two main objectives: operationalising the Paris Agreement by adopting detailed rules for its implementation, and starting the process of strengthening Parties' climate protection contributions. This article covers the negotiations on these two sets of issues and also includes a discussion of other recent climate activities by Parties and non-Party actors. Success of the negotiations in Katowice was far from assured, but in the end COP24 concluded with the adoption of the "Katowice Climate Package" setting out detailed guidelines on how to implement its various elements. However, the conference fell short on the first objective, none of the major emitting countries was ready to step up its climate ambition. The most important aspect of the Katowice outcome is therefore that it has brought the wrangling about implementation procedures to a close, making way for the true task at hand: the strengthening of national and international activities to protect the climate and the implementation of the existing pledges. Arguably, a key factor that has been slowing down climate policy is the power of entrenched interests. The article therefore concludes with a reflection on how such barriers to climate action may be overcome and what role future COPs may play in this regard.
