Double chat showing the EU LNG imports from non-EEA countries from 2019 to 2025, in bcm and as share
Based on a novel analysis covering the entire European Economic Area (EEA, notably including Norway), this policy brief shows that US gas imports into the EEA sharply surged in 2025. They now account for almost 40% of total EEA gas imports and nearly 60% of LNG imports. This trend exposes Europe to heightened geopolitical pressure, price volatility and the risk of stranded assets.

This report contributes to a better understanding of the economic implications of climate change adaptation across the European Union. Its central objective is to analyse three key dimensions: the costs of adapting to climate change, the costs of inaction, and current levels of adaptation funding. The analysis focuses on three climate-sensitive sectors of strategic importance for the EU economy and society: transport, energy, and agriculture.

The triple planetary crisis is a systemic challenge, not three separate issues: climate change, biodiversity loss, and pollution reinforce one another through shared drivers and feedback, threatening planetary and human well-being. It is driven by fossil fuel dependence, unsustainable production and consumption, overexploitation of land and resources, and structural inequalities. The analysis concludes that the triple crisis can only be effectively addressed through systemic, cross-sectoral, and justice-oriented approaches. By linking resource governance, NbS, and transformative change, this report highlights how today’s triple crisis can be turned into an opportunity to regenerate ecosystems, reduce inequalities, and build resilient societies within planetary boundaries.

Nature-based solutions are central to climate change adaptation. Urban green spaces and waterbodies can reduce heat in cities, for example. How can local authorities implement such measures despite limited resources? This paper presents financing options based on practical examples – from crowdfunding to green bonds – and assesses which ones are suitable and when. It also provides recommendations on how the federal and state governments can provide support.

The present report discusses criteria that could reasonably be applied to prioritise downstream products for inclusion in CBAM. It examines the significance and suitability of different criteria, as well as the availability and reliability of data to operationalise these criteria.

This study investigates instruments that could generate revenue for international climate finance. Through a mixed-methods approach, including desk research and interviews with 23 experts from diverse professional backgrounds, the study evaluates four proposed levies: a Fossil Fuel Extraction Levy, a Levy on Windfall Fossil Fuel Profits, a Levy on Plastic Polymers, and a Levy on Jet Fuel.

carbon removals in the EU
While cutting emissions remains the primary objective of EU climate policy, achieving climate neutrality and eventually net-negative emissions will also require large-scale deployment of carbon dioxide removal (CDR) solutions. This report provides an overview of the current state and future potential of permanent CDR in Europe.

This report explores options for an EU purchasing programme for permanent carbon removals to address a critical gap in climate change mitigation. While emissions reductions remain the primary objective of EU climate policy, achieving climate neutrality and eventually net-negative emissions necessitates the large-scale deployment of carbon removals. This requires the swift development and deployment of cost-effective and socially beneficial carbon removal technologies.

Cover page of the report “International Oil Extraction Levy – Design recommendations and impact analysis,” published by Ecologic Institute and the Federal University of Rio de Janeiro (UFRJ). Authors: Prof. Dr. Luan Santos, Dr. Michael Jakob, Jonathan Gardiner, Flora Dicke, and Benjamin Görlach. Publication date: 27 June 2025.
This report explores the design and implications of an international oil extraction levy as a mechanism to mobilize new sources of climate finance. The assessed levy places a price on the embedded CO₂ in extracted crude oil, increasing production costs and likely raising oil prices for final consumers. By internalising part of the climate costs of fossil fuels, the mechanism aligns with the polluter pays principle.

This report published under the EU-funded GoNaturePositive! project offers a comprehensive baseline assessment to support the transition toward a nature-positive economy. The report provides an in-depth analysis of EU policy instruments and co-operative initiatives, identifying their alignment with nature positive principles and opportunities to reduce environmental harm, restore ecosystems, and foster systemic change.

This report presents the conclusions of the study titled "Macro-economic / Top-down Assessment of Climate Impacts on the EU Economy." Commissioned to assist the European Commission’s Directorate-General for Climate Action (DG CLIMA), the study explores how climate change-induced hazards may influence the EU's socio-economic landscape. Its central aim is to deliver both qualitative and quantitative perspectives on the broader macro-economic effects of significant climate hazards. It also investigates how these climate-related shocks ripple through different sectors of the economy. By compiling and analysing relevant data, the study provides a knowledge base to help the European Commission assess how such impacts could potentially challenge the EU’s ability to meet its climate mitigation objectives.

The analysis by Ariadne project partners examines Germany's climate foreign policy during the current legislative period. Beyond the international context, they also consider the organizational structure within the German government and the responsible ministries. The researchers conclude that Germany has been able to set the pace for international climate policy by transferring the responsibility for international climate policy to the Foreign Office and creating the role of Special Envoy for International Climate Policy. In contrast, the record of Germany's engagement in bilateral and plurilateral formats has yielded mixed results.
