The United States (U.S.) and China are key to meeting the goals of the Paris Agreement and reaching carbon neutrality by around mid-century. Despite differences, carbon neutrality will be met more rapidly if the two countries coordinate and facilitate synergies in carbon-neutral technologies and policy development and implementation. Building on long-term pathway models in the U.S. and China, current emissions trends and sources, and a policy analysis, this paper puts forward a novel framework for U.S.-China coordination on carbon neutrality. The analysis reveals similar technology and policy pathways, policy gaps, and shared milestones for decarbonization in 2030, 2040, and 2050-2060. The main technological pathways focus on reductions in energy demand and non-energy-related CO2 emissions, decarbonization of electricity and fuels, and increases in electrification rates and CO2 sequestration. Given existing domestic policies and opportunities for further action, areas for coordination on carbon neutrality include common policy milestones; dialogue and technical exchange; research, development, and demonstration (RD & D); and international climate leadership. Despite escalated tensions between the U.S. and China, and challenges for climate cooperation, coordination between both countries on carbon neutrality is both possible and necessary.Key policy insightsCarbon neutrality will be met more swiftly if the U.S. and China coordinate and facilitate synergies in carbon-neutral technologies and policy.Despite the rise in geo-political tensions between the U.S. and China, coordination on carbon neutrality is both possible and necessary.An analytical framework for U.S.-China coordination on carbon neutrality, includes technology and policy pathways, and common milestones of key sectors' decarbonization for 2030, 2040, and 2050-2050.The two countries could coordinate on common policy milestones, dialogue and technical exchange, research and development, and international climate leadership.
