Based on the available literature, this report explores the impacts of production and trade-distorting domestic support in agriculture on climate (i.e., greenhouse gas emissions) and the environment (i.e., water, biodiversity, and land degradation).

It is unlikely that the deployment of CO2 removal (CDR) at the required scales will happen as a side effect of other policies. Large-scale CDR deployment will not happen by accident, but needs time, incentives, and clear rules. Without strategic orientation, it is also hard to balance the multiple implications of each CDR option for societies, economies and ecosystems. Member States' CDR strategies could be a first step to trigger the necessary public debate and to help create an adequate framework for CO2 removal.

The regulatory framework for the transformation to a climate-neutral industry has evolved. To take account of the changes, we have revised our analysis on the role of climate protection contracts in the steel industry, which was mainly based on data from 2020. This updated study analyzes how climate protection agreements in the steel industry can be designed in such a way that – in conjunction with the reform of European climate policy – they have an impact on climate protection, energy security and a meaningful transformation of the economy as a whole.

Energy prosumption through the deployment of residential renewable energy technologies reduces greenhouse gas emissions, speeds up the energy transition and provides important community benefits. In a new report, the European Environment Agency assesses energy prosumption models used throughout the EU and recommends policy tools that can allow even more EU citizens to benefit from energy prosumption. The publication builds on a study produced by CE Delft, Fraunhofer ISI and Ecologic Institute.

This report provides the context and justification for the development of BE-Rural's Sustainability Screening, a description of its methodological procedure, and the syntheses of results from the two experimental implementations of the approach in the Stara Zagora and Vidzeme regions, which are included in full as annexes to this report. The last chapters present the main lessons learned from these two pilots and the overall conclusions of the task.

How does subsoil management affect the provision of ecosystem services – and what is its economic value to society? These questions are at the heart of a study by Sophie Ittner, Holger Gerdes and Zoritza Kiresiewa from Ecologic Institute. Using a Benefit Transfer approach, the authors assess the societal costs and benefits of two subsoil management practices in German agriculture. The results demonstrate that sustainable subsoil management can generate not only ecological, but also substantial economic value – offering important insights for targeted support through agri-environmental policy.

In March 2022, at the resumed fifth meeting of the United Nations Environment Assembly, UN Member States adopted the historic decision to start negotiating a global treaty to combat plastic pollution. As national delegations and relevant stakeholders in Asia start preparing for the upcoming negotiations, this report by Linda Mederake and Doris Knoblauch (both Ecologic Institute), aims to provide an analysis of the region’s opportunities to end single-use plastics (SUPs) pollution through the development of this new global treaty.

In this Ariadne publication, experts from Ecologic Institute, Potsdam Institute for Climate Impact Research, RWI – Leibniz Institute for Economic Research, Mercator Research Institute on Global Commons and Climate Change, Stiftung Umweltenergierecht, ZEW – Leibniz Centre for European Economic Research and IER Stuttgart analyzed various options for the relief and level of the CO2 price – and identified advantages and disadvantages as well as implementation requirements of different design options. The focus is on two key political points of contention, where scientific findings can prevent an impending hardening of the position and thus promote a consensus that is conducive to climate protection.

This German-language abridged version summarizes the findings.

The aim of this strategy paper is to summarise the results of the National Dialogue on Food Systems on the two thematic areas "Food Economy of the Future" and "Food of the Future – More Plant-Based", particularly with regard to the policy options and instruments discussed there.

This report analysed if and how EU Member States used their auctioning revenues from the EU Emissions Trading System (ETS) for climate action. For this purpose, we selected eight case study countries, namely Czech, Germany, Greece, France, Italy, the Netherlands, Poland, and Portugal. As part of these case studies, we examined the reporting, the legal provisions and the political narrative around auctioning revenues through desk research and expert interviews.

As part of the project Dialogue Forum "Private Households", a mapping of existing actors and initiatives in Germany was carried out and evaluated. The aim of this structured categorisation is to gain an overview of the current landscape of measures in order to identify which effective starting points are already covered by current measures and which are not, and how existing measures can be improved and their effectiveness increased.

The publication summarizes the key messages from all 20 joint research projects and the seven cross-cutting topics of the German research focus "Plastics in the Environment". Structured by main topics, the central results are presented in order to derive recommendations for various addressees. More than 70 researchers and practitioners from across the research focus have jointly co-authored the key messages.

This report takes stock of emission trajectories, climate policies and complementary policies in G7 countries. It helps to identify gaps in the existing policy landscape of global decarbonisation efforts and proposes potential improvements. Based on these insights, we consider that G7 countries have many viable options for accelerating the global energy transition.

This paper describes important findings from the project "Data Governance and Regulation for a Sustainable Berlin" and formulates – in addition to the application field-specific papers – overarching recommendations.
