Who We Are
The Office of International Economic Opportunity develops and provides rigorous quantitative analysis of global energy markets and energy policy and quantifies the domestic economic benefits of bilateral and multilateral investments in a global clean energy transition. Through extensive analysis, the Office advances efforts to improve global energy security by reducing reliance on energy supplies from malign exporters.
Initiatives
- Monitor international energy markets to inform Department leadership of critical developments in trade and geo-economics
- Provide technical oil markets research and analysis in the design and implementation of a price cap on Russian oil exports
- Analyze current trade flows to assist in compliance and enforcement of sanctions and other export restrictions
- Lead natural gas and LNG analysis to support the U.S.', EU allies’, and the IEA's efforts to reduce natural gas demand and ensure supply security in response to Russia’s weaponization of energy supplies
