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 document serves as an informational pre-read for the workshop Perspectives on a Purchasing Programme for CRCF Permanent Carbon Removal Credits, that took place on 21 May 2025 in Brussels, hosted by DG CLIMA.

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.

This document assesses the just transition aspects of Germany's draft updated National Energy and Climate Plan (NECP). Specifically, it focuses on how well the plan addresses the territorial and distributional challenges of transitioning to climate neutrality.

In this article, the authors, including Anthony Cox of Ecologic Institute, highlight there is little appetite among WTO members for modernizing multilateral subsidy rules at a time when many countries are introducing new forms of support that could potentially exacerbate existing policy disincentives for globally sustainable economic and environmental outcomes.

This UNITED project business brief discusses the legal framework and environmental implications of a project in the Greek Aegean combining aquaculture and tourism, including laws and regulations, particularly in relation to marine conservation, permitting and marine spatial planning.

This UNITED project business brief discusses the legal framework and environmental impacts of a project in the German North Sea that combines offshore wind energy and aquaculture, including the laws and regulations that apply to offshore installations in the German Exclusive Economic Zone (EEZ).

This Business Brief of the UNITED project examines the legal and environmental aspects of a project that successfully combines offshore wind energy production with innovative tourism activities.

This UNITED project business brief examines the legal and environmental aspects of a Belgian project using offshore wind farms in the North Sea for the cultivation of flat oysters and seaweed. Particular attention is paid to environmental benefits, such as improved water quality and biodiversity, as well as potential challenges, including permitting procedures.

How can companies and societies effectively design the shift towards greater sustainability? This policy brief highlights the importance of sustainable production methods, investments, and nature-positive supply chains for the restoration of ecosystems and outlines action approaches for a sustainable future.

In an increasingly interlinked and globalized world, indigenous peoples and local communities are essential for the preservation of their rights, cultures and access to land and resources. What role do they play in the dialog around environmental protection and social justice? This policy paper sheds light on the challenges and opportunities for indigenous peoples and local communities and explores how their voices can be heard and respected in international forums.

As competition for, and interest in, use of ocean space increases, a need for management arises to optimize activity in marine areas. This policy brief provides a comprehensive consideration of the economic efficiency of marine multi-use (MU) by weighing the pros and cons of individual use options against potential MU combinations.

Households across Germany felt the weight of 2022's energy crisis, grappling with a dramatic increase in energy prices. Overall energy costs in Germany surged by 31% in 2022 compared to the previous year. To combat the adverse impacts of the 2022 energy crisis, Germany passed three major relief packages in 2022. This country briefing paper describes Germany’s policy response to the energy crisis of 2022 and provides a microsimulation-based summary of the distributional effects of energy price shocks on German households.
