With the Fit for 55 package, the European Commission made far-reaching proposals in July 2021 to align the architecture of European climate policy with the goal of climate neutrality. These proposals include the strengthening of the existing emissions trading scheme, the introduction of new emissions trading for transport and buildings, a border adjustment mechanism (CBAM) to protect against carbon leakage and the tightening of regulatory instruments for transport and buildings. However, the proposals raise a number of questions – from distributional effects and acceptance to the consistency of the instruments. In the course of this two-day hybrid event, researchers from the Ariadne consortium discussed these issues with stakeholders and decision-makers at the European level.

This project looks at the distributional effects of energy tax reform across Europe and develops recommendations for making the reforms socially and environmentally sound. Ecologic Institute contributes to this project with its expertise of German energy taxation and will translate the findings of the modelling exercise to the German context.

Climate protection for 1.5 degrees calls for fundamental changes in many areas, but not in Germany's democracy. Nils Meyer-Ohlendorf discusses the relationship between climate protection and democracy in an article for the Tagesspiegel.

Regions play a central role in achieving the substantial acceleration of renewable energy deployment required to reach the 2030 greenhouse gas reduction targets. The report "The socio-economic impacts of renewable energy in EU regions: Strengthening local benefits" examines the socio-economic effects of renewable energy deployment at the regional level in the EU and subsequently identifies factors that are conducive to an equitable energy transition. As part of the report, this case study by Ecologic Institute analyzes the role of renewable energy and its socio-economic imparts in the North German region Mecklenburg-Western Pomerania. The analysis was done for the the Greens/European Free Alliance.

The results of the research focus "Plastics in the Environment" will be presented in a webinar series. The participation in the webinars is free of charge; registration in advance is required.

With the Green Deal, the European Union aims to reduce its greenhouse gas (GHG) emissions by at least 55 percent by 2030 compared to levels in 1990. Among other things, this goal is to be achieved through a stronger role for carbon-pricing. For industry, however, this plan carries the risk of "carbon leakage": energy-intensive industries such as steel or chemical production could move away – increasing emissions elsewhere. Other industries could also be indirectly affected. This policy brief analyzes the types of measures available to reduce risks for industry and embeds them in two basic strategies that can be pursued with regard to carbon leakage.

From sector coupling to hydrogen, from the implementation of the Climate Protection Legislation to the European Green Deal: Achieving climate neutrality requires coordinated and effective policy management across individual departments. Climate policy is a cross-cutting task, because all sectors, from power generation to industry, buildings, transport and agriculture, must become greenhouse gas neutral without delay. Experts from the Ariadne Copernicus project, which is funded by the German Federal Ministry of Education and Research (BMBF), have examined central problems of government control of German climate policy and presented options for solutions. The paper was also sent to negotiators of the coalition talks in the run-up to publication.

All over the world, the number of think tanks is growing. They differ greatly regarding their focus areas, their structures and their business models. But what do they have in common and why are they needed? In an interview with André Martinuzzi of the European Sustainable Development Network (ESDN), Dr. Camilla Bausch (Director of Ecologic Institute) reflects on the role and the objectives of environmental think tanks with respect to some of the most relevant policy fields of our times, including the European Green Deal.

The year 2021 saw a positive dynamic on climate action internationally, despite the pandemic and its negative impacts on people’s well-being and on the global economy. Especially, the reverse in the US approach to the climate crisis has provided a new boost. Moreover, COP26 in Glasgow created political momentum, as it has shown a global spotlight on the need for international action and on various forms of cooperation to achieve the 1.5 °C target. In 2022, there are several windows of opportunity for further advances in multilateral cooperation on the climate crisis, including in the G7 and G20 discussions, led by Germany and Indonesia, respectively. And the new German government has reiterated its desire to create a new "climate club" in this context. This report contains several proposals for specific new initiatives that could be started.

The briefing provides a didactic overview on carbon farming. Specifically, it summarizes the current scientific understanding of the mitigation potentials, co-benefits and trade-offs of carbon farming, as well as the key agronomic practices and key knowledge gaps that need to be addressed to scale up carbon farming and to deliver robust climate mitigation and EU Green Deal objectives.

In Tanzania, the majority of the rural population still relies on fuelwood as their major source of cooking energy. The adaptation measures of small-scale farmers in response to increasing fuelwood scarcity play a key role in altering the course of nutrition insecurity, environmental degradation, and economic instability. This study delivers a classification of coping strategies that does not exist in the literature. Furthermore, it analyses the adaptation measures applied by small-scale farmers in the semi-arid region of Dodoma district in response to fuelwood scarcity. A comparison between two case study sites provides information on the choice of adaptation measures by households. Overall, 28 coping strategies from 24 studies are identified, then differentiated into preventive and acute measures that are arranged into eight clusters.

The European Consumer Food Waste Forum is a multi-disciplinary forum set up in October 2021 by the Joint Research Centre, which seeks to enable the EU's transition to a sustainable food system by finding solutions and developing tools that help to reduce food waste at the consumer level, including household and food services. Stephanie Wunder and 15 other practitioners and researchers will identify and develop multi-dimensional tools to curb consumer food waste, considering both the motivation of consumers as well as their ability and opportunity to change related behaviour. The tools will be multi-level addressing both the role of consumers and that of other key players engaged in food waste reduction. These will contribute to the work of the EU Platform on Food Losses and Food Waste and that of other players to help reduce consumer food waste.

Climate lawsuits have become a frequently chosen tool in the fight for more ambitious climate policies in recent years. In the extensive reporting on this topic, one aspect has so far been neglected: the differences between the jurisprudence in the Global South and the Global North. To address the related issues, Verfassungsblog, Völkerrechtsblog and the journal World Comparative Law (WCL) in cooperation with the Ecologic Institute are organizing an online symposium on the subject of "Comparative Climate Litigation in North-South Perspective".

In this review, Ecologic Institute's Doris Knoblauch and Linda Mederake analyse the subject focus of 45 articles (published 2019–2021), dealing with government action to regulate plastic pollution. Policies described in the articles and introduced between 2016 and 2021 are clustered in four categories: production – consumption – disposal – circular approaches. The article is open access and available for download.
