As the Department’s lead on international energy issues, the Office of International Affairs is responsible for directing diplomatic outreach, leading multilateral energy negotiations -- including in ministerial-level energy tracks in the G7, G20, APEC where the Secretary of Energy represents the U.S  --  and developing energy policies to advance the administration’s global climate, economic, and security goals through cooperative platforms like the International Energy Agency, the Clean Energy Ministerial, and Mission Innovation.

The Office has primary responsibility for analysis, risk assessment, and formation of response measures with other parts of the U.S. government to address international energy conflicts and opportunities that have a direct impact on research, development, utilization, supply, and conservation of energy affecting the United States.
