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.
Global climate
(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.
The transformation of cities towards sustainable and inclusive development is a key objective of the New Urban Agenda (United Nations 2017). Transport infrastructure is a critical factor in shaping cities, determining the energy intensity of mobility and providing access to essential social and economic opportunities. The sector also plays an important role in global climate change mitigation strategies, as it currently accounts for about 23% of global energy-related greenhouse gas emissions (IPCC 2014).
There is substantial potential to improve urban access, air quality, safety and the quality of life in cities along with reducing Greenhouse Gas Emissions if an integrated policy approach is applied that combines all intervention areas for transport policy and involves all levels of government. A package that achieves low-carbon transport and fosters sustainable developed includes avoided journeys through compact urban design and shifts to more efficient modes of transport, uptake of improved vehicle and engine performance technologies, low-carbon fuels, investments in related infrastructure, and changes in the built environment. From a governance perspective, all relevant political institutions at the local and national level need to be involved in the coalition building along with key societal actors, such as unions, industry and civil society organisations. Bringing the policy objectives of these actors together with an integrated policy package is a vital step towards a low-carbon, sustainable mobility system.
Policy design and governance are critically interlinked as the ability of institutions to find a political consensus and to maintain policy stability heavily influences the success of measures to shape the transformation pathway towards sustainable mobility. This thesis aims to analyse these linkages and highlight the role of different policy and governance approaches. This analysis builds on transport and urban development research, but takes a transdisciplinary research perspective, building on the Multi-Level-Perspective on sustainability transitions (Geels 2002) and aims to highlight the potential for a consensus oriented policy approach (Lijphard 1999) that builds on co-benefits among key policy objectives and coalitions among key political actors, which leads to the main question for this thesis and the focus areas for the analysis.
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.
Nun, es könnte wahrscheinlich auch anders sein : Eingriffspunkte einer Möglichkeitswissenschaft
(2019)
Mit "InnovationCity Ruhr - Modellstadt Bottrop" soll ein typisches Stück Ruhrgebiet mit rund 70 000 Einwohnern bis zum Jahr 2020 klimagerecht umgebaut werden. Benjamin Best rekonstruiert den Partizipationsprozess des Projektes, er analysiert seine Begrenzungen und zeigt Weiterentwicklungsmöglichkeiten auf. Die empirische Studie basiert auf qualitativen Methoden der empirischen Sozialforschung, auf teilnehmenden Beobachtungen in der Modellstadt und der Teilnahme an ausgewählten Beteiligungsveranstaltungen. Mittels Interviews mit Expertinnen und Experten identifiziert der Autor kulturelle Faktoren, die die Form der Partizipation im Kontext von InnovationCity sowie den Verlauf des Gesamtprojektes bestimmt haben.
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.
Each year, approximately one-third of the food produced for human consumption is lost or wasted worldwide. The waste of resources used for this food has significant environmental impacts in terms of land and water use as well as greenhouse gas emissions. Consequently, one of the targets of the UN sustainable development goals is to halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains by 2030. However, sufficient knowledge about the suitability of instruments for food waste prevention is still lacking. The purpose of this paper is therefore threefold: first, it outlines the generation and causes of food losses and waste. Second, it discusses good practices from different countries, such as laws to reduce food waste, voluntary agreements, awareness campaigns and results from behavioural economics. Finally, based on these findings, this paper identifies barriers to as well as requirements for the implementation of effective and efficient instruments.
Europa braucht eine neue Fortschrittsvision. Eine Energiewende hat dieses Potenzial. Sie kann der "Europäischen Idee" einen zukunftsorientierten Inhalt geben. Das Ziel für 2050 ist klar: ein Europa ohne fossile und nukleare Energie! Das ist keine Utopie. Studien, Beschlüsse der EU und einiger Mitgliedsländer belegen, dass diese Vision machbar und mit vielen Vorteilen verbunden ist: mehr Jobs, mehr Versorgungssicherheit, weniger vorzeitige Todesfälle durch Luftverschmutzung, Abbau von Ressourcenkonflikten, sinkende Energiekosten. Neue grüne Leitmärkte für erneuerbare Energien und Ressourceneffizienz entstehen. Eine europäische Energiewende erfordert eine Allianz, idealerweise angefeuert durch die Nachbarn Frankreich und Deutschland. Viele hoffen auf Deutschland als Treiber von Atom- und Kohleausstieg. Aber "revolutionäre Ziele" zu beschließen ist nicht genug: Sie endlich umzusetzen - darauf warten Deutschland und Europa. Dieses Buch zeigt, welche konkreten Schritte diese Fortschrittsvision voranbringen werden.
