Asia-Pacific Economic Cooperation (APEC), established in 1989 in response to strong economic growth across the region, is an economic forum for 21 Asia-Pacific economies.

The IEA participates actively in APEC summits, organises trainings and provides information, especially on energy efficiency and energy technology, to support APEC in efforts to promote sustainable growth. In 2017, the IEA published the paper Tracking Fossil Fuel Subsidies in APEC Economies

In October 2015 the IEA signed a Statement of Intent with the APEC Energy Working Group at the APEC Energy Ministers Meeting in Cebu, Philippines. This statement builds upon many years of extensive co-operation, and seeks to expand collaboration in areas including energy security, energy data and statistics, renewable energy, fossil fuel subsidy reform, energy market analysis, and capacity building.
