Building on The U.S.-China High-Level Event on Subnational Climate Action held in Berkeley in May, and the U.S.-China Subnational Climate Action Roundtable held in Beijing during Senior Advisor to President Biden for International Climate Policy John Podesta’s trip to China in September, this dialogue, held on the margins of COP29 in Baku, featured top subnational climate leaders from the U.S. and China, sharing the latest action, progress and challenges at the state and city level. Its aim was to draw out the key ways that subnationals are helping to implement the Sunnylands Statement, and driving ambitious climate action.
