OECD Secretary-General Report to G20 Finance Ministers and Central Bank Governors on the work of the Inclusive Forum on Carbon Mitigation Approaches (United States, April 2025)

This report presents the latest developments with the Inclusive Forum on Carbon Mitigation Approaches (IFCMA).

With 60 members and numerous countries engaging as invitees, the IFCMA is bringing together diverse national perspectives and building a common understanding of the broad range of mitigation policies and their effects. The intent is to facilitate more coherent and better co ordinated mitigation policies across countries, to help avoid negative cross-border impacts such as carbon leakage or trade distortions, while maximising opportunities for innovation, cost savings and shared benefits from the climate transition.
