The Office of Global Change in the Bureau of Oceans and International Environmental and Scientific Affairs (OES/EGC), in coordination with the Special Presidential Envoy for Climate (SPEC), is responsible for the implementation and management of U.S. international climate change policy, climate foreign assistance programs, and strategic climate bilateral and multilateral partnerships.

OES/EGC represents the United States in negotiations under the Paris Agreement and the United Nations Framework Convention on Climate Change (UNFCCC), and in climate-related negotiations in other international fora, such as the International Civil Aviation Organization, the International Maritime Organization, the G7, and the G20. The office also leads U.S. government participation in the Intergovernmental Panel on Climate Change (IPCC), which assesses scientific and technical information related to climate change. In addition to informing policy, OES/EGC oversees U.S. foreign assistance programs globally supporting clean energy development and deployment, enhancing adaptation and resilience to climate change, and reducing emissions from deforestation and other land uses, while conserving and restoring ecosystems. The office undertakes strategic planning, budgeting, project development, and monitoring and evaluation of OES-funded climate programs.
