Fossil fuel subsidy reform can contribute to both climate change and sustainable development goals. However, subsidies to fossil fuel consumption and production continue to persist in developed and developing countries. International cooperation can play an important role in promoting or hindering reform. This chapter examines the coherence of international governance of fossil fuel subsidy reform. The chapter discusses the emergence of a core norm of fossil fuel subsidy reform, the distribution of membership across international institutions, and the various governance functions fulfilled by the international institutions active in this area. To further assess coherence, the chapter focuses on a subset of three international coalitions active in the area of fossil fuel subsidy reform: the Group of 20 (G20), the Asia-Pacific Economic Cooperation (APEC), and the Friends of Fossil Fuel Subsidy Reform. The chapter identifies an emerging division of labour, with different institutions taking charge of various governance functions. Where activities do overlap, they generally appear to reinforce one another. With respect to the G20, APEC, and the Friends of Fossil Fuel Subsidy Reform, the high level of consistency appears to be the result of planned coordination, overlapping memberships, as well as a brokering role taken on by some countries. test
