TheInclusive Forum on Carbon Mitigation Approaches (IFCMA) is the OECD’s flagship initiativedesigned to help optimise the global impact of emissions reduction efforts around the worldthrough better data and information sharing, evidence-based mutual learning and better mutualunderstanding, and inclusive multilateral dialogue. The IFCMA is enhancing understanding of the full spectrum of carbon mitigation approaches deployedaround the world and their combined global impactby taking stock of different carbon mitigationapproaches, mapping policies to the emissions they cover, andassessingtheir impacts on emissionsthrough modelling and by reviewing empirical evidence. The IFCMA is also identifying and addressingchallenges relatedto the calculation of sector-and product-level carbon intensity metrics, tosupportthedesign and evaluation of mitigation policies, andenable the development of markets for low-carbongoods.This work supports better international co-ordination to avoid the proliferation of differentstandards, help minimise compliance costs for businessesand avoid disruptions to trade. There are currently60IFCMA members, including14 G20 membersand 6 G20 invitees: Table ofcontents 1.Overview52.Inclusive multilateral dialogue63.Advancing international cooperation on carbon intensity metrics74.Delivering the IFCMA Climate Policy Database by end of 202595.Assessing mitigation policies’ impact106.Next steps11Further resources12IFCMA Plenary Meetings12IFCMA Paper series12 1.Overview I am pleased to report onthelatestdevelopmentswiththe Inclusive Forum on Carbon MitigationApproaches (IFCMA).With60membersand numerous countriesengaging as invitees, the IFCMA isbringing togetherdiversenational perspectives and buildingacommon understanding ofthe broad rangeofmitigationpolicies and their effects.The intentistofacilitatemorecoherent and betterco-ordinatedmitigation policiesacross countries, tohelpavoidnegative cross-border impacts such as carbon leakageor trade distortions,whilemaximisingopportunities for innovation, cost savings and shared benefits fromthe climate transition.
