The Third Paris Report calls for a bold new global strategy to align climate, nature, trade, and finance. With emerging economies central to future climate outcomes, the report outlines a four-pillar plan: carbon pricing coalitions, clean energy investment, green industrial partnerships, and innovative carbon removal markets. In a fragmented world, it urges coalitions of the willing to drive a just, nature-positive transition.

This report forms the second output from a joint initiative between CEPR and Bruegel: Important Topics of Common European Interest (ITCEI).  The editors, Jean Pisani-Ferry (Sciences Po, Bruegel and CEPR), Beatrice Weder di Mauro (Geneva Graduate Institute, Hoffmann Center, and President, CEPR) and Jeromin Zettelmeyer (Director, Bruegel, and CEPR), lay out a coherent, actionable plan for advancing the global commons in an era of political fragmentation. It draws on the strengths of advanced economies, the renewable potential of developing nations, and the growing role of subnational actors to propose variable-geometry coalitions capable of moving the needle where universal frameworks have stalled.

The result is not only a set of proposals, but a blueprint for climate and biodiversity action that is as realistic as it is ambitious. Join Jean Pisani-Ferry, Beatrice Weder di Mauro, Jeromin Zettelmeyer, and chapter authors Patrick Bolton and Kim Clausing, for an online presentation and discussion of the Report, which was launched on Tuesday 1 July 2025. The webinar will be moderated by Tim Phillips (CEPR).
