David W Yellen is the director of climate policy innovation at Clean Air Task Force (CATF). He leads CATF’s work analysing the global impacts of new and emerging climate policies, its work in the Middle East and on cross-regional policy, and on how energy transition strategies intersect with geopolitical and economic imperatives across regions. He works closely with CATF’s regional teams to identify cross-cutting issues, provide industrial and geopolitical analysis for guiding strategy, and develop opportunities for international co-ordination that would advance decarbonisation and development.

Previously, Mr Yellen was an associate director at the Atlantic Council Global Energy Centre, where he was responsible for Asia-Pacific research and programming, as well as the centre’s hydrogen work, and he contributed to energy security and markets research. He also previously worked at the Council on Foreign Relations on clean energy economics and in US Senator Elizabeth Warren’s office, and he has contributed pieces to Scientific American and The Economist, among other publications.

Mr Yellen has a master of science degree in environment and sustainability management from Georgetown University, from which he also graduated summa cum laude with a bachelor’s degree in government, with a focus on energy markets and policy and a minor in economics. He is also a nonresident fellow at the Atlantic Council Global Energy Centre and represents CATF on the US Department of Commerce’s Environmental Technologies Trade Advisory Committee.
