This series explores ways in which the United States and China can coordinate their near-term and mid-term efforts to achieve carbon neutrality by around the middle of this century, based on a review of deep decarbonization pathways studies in both countries. The series includes three reports: a synthesis report that develops a framework and proposes milestones for U.S.-China coordination on carbon neutrality, and two supporting reports that review and analyze recent deep decarbonization studies in the United States and China, respectively. This report contains the U.S.-China framework and milestones for carbon neutrality.
