This report presents a vision and a concrete roadmap for U.S.-China  collaboration focused on reducing greenhouse gas emissions to mitigate the effects of climate change. The report was produced in partnership between the Pew Center on Global Climate Change and the Asia Society’s Center on U.S.-China Relations, in collaboration with The Brookings Institution, Council on Foreign Relations, National Committee on U.S.-China Relations, and Environmental Defense Fund. Experts and key stakeholders from the worlds of science, business, civil society, policy, and politics in both China and the United States contributed to the report, or “Roadmap,” that explores the climate and energy challenges facing both nations and recommends a concrete program for sustained, high-level, bilateral engagement and on-the-ground action.
