This paper reviews a secretive Joint Statement (JS) on Gas Supply Security to Central and Eastern Europe that was signed in Washington, D.C., on 24 February 2026 on the sidelines of meetings organised by the White House, its ‘National Energy Dominance Council’, and the ‘Donald J. Trump Institute of Peace’. Signatories comprise the US, eight EU Member States and four candidate countries.

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.

This paper examines the penalty provisions in the draft Czech implementing law submitted on 11 November 2025 by the Minister for the Environment to the Prime Minister. It briefly considers the draft's legislative status in light of the political situation following the 3–4 October general election, assesses its compliance with the EU-MER, and compares it with good practice in Denmark and with Italy's draft law.

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.

The EU must rethink its energy security in light of increasingly renewable, decentralized, and electrified energy systems. Energy security already benefiting from the early start of the energy transition. In the transition phase now beginning, a forward-looking and adaptable approach is needed to maximize synergies and manage potential conflicts between decarbonization and energy security.

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.

Cover of Ecologic Institute's report entitled "Integrating Hydrogen Emissions Into the EU Policy Framework. Why hydrogen emissions matter, when they will become significant, and how the EU can tackle them"
While hydrogen (H2) emissions make up a negligible fraction of today's GHG emissions, they are set to become more significant in the 2030s and, should the EU and the global community progress towards climate neutrality, will likely be substantial in the 2040s, as achieving climate neutrality requires the expansion of hydrogen use alongside the rapid reduction of other GHGs. As decisions made today will shape hydrogen value chains for decades, this paper develops a series of policy proposals to implement a four-pronged strategy.

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.

Cover page of the final report titled 'Rechtsgutachten zur Krisenfestigkeit des EU-ETS' (Legal Opinion on the Resilience of the EU-ETS). The report is part of the 'Climate Change 43/2024' series. Authors include Lina-Marie Dück and Madeleine Pumberger from the Ecologic Institute in Berlin, and Michael Jakob from Climate Transition Economics, Berlin. The report is published by the Umweltbundesamt (German Environment Agency), and the blue cover features the Umweltbundesamt logo at the bottom.
This report analyses the resilience of the European Emissions Trading System (EU ETS) and shows how global crises such as the COVID-19 pandemic or the war in Ukraine can affect its operation. In view of rising energy prices and economic uncertainties, it becomes clear that the EU ETS needs to improve its legal resilience to crisis situations. The report highlights necessary reforms to make emissions trading more resilient and effective in the future.

The EU Methane Regulation (EU-MER) is crucial for reducing methane (CH4) emissions from the energy sector, thereby enhancing our chances at achieving the climate targets. This paper discusses the respective roles of the responsible ministries (RM) and the competent authorities (CA) and examines how the CA's tasks can be allocated to various pre-existing agencies at the national or regional level. Additionally, the working paper discusses the importance of political autonomy for CA and how MS can prevent undue influence.

This publication discusses the penalty regime to be established by the EU Member States to sanction infringements against the recently adopted EU Methane Regulation (EU-MER). In these regimes, (administrative) fines will play a major role. The EU-MER stipulates that the level of fines must be proportionate to the environmental damage and impact on human health associated with the infringement as the core criterion. The working paper proposes applying a core reference value of 6.000 EUR/tCH4 to be adjusted according to the aggravating or mitigating factors foreseen by the regulation.

To achieve the ambitious climate targets of the Federal Climate Change Act a rapid expansion of renewable energies, particularly wind and photovoltaics (PV), is crucial. In this context, achieving 215 GW of installed PV capacity by 2030 has become a specific target of the Renewable Energy Sources Act (EEG). This report deals with the central role that buildings play in meeting PV expansion targets, with the potential to cover up to 25% of EU electricity consumption through rooftop PV.
