Supported and advised by Energy Foundation China, this analytical report on U.S.-China methane collaboration roadmap released in November 2022 was led and coordinated by the Center for Global Sustainability at the University of Maryland, with contributions from 25 authors from eight research organizations around the world.

This report provides new, in-depth analysis of opportunities and challenges for methane mitigation in the U.S. and China, as well as opportunities for improving methane mitigation outcomes through collaborative activities and research. It provides a comprehensive overview of the current methane emissions, policy frameworks, and mitigation opportunities in both countries. It also identifies options for methane mitigation and sheds light on opportunities for collaboration between the U.S. and China in terms of inventory development, policies and standards, and technology deployment. Moreover, building on new, multi-model analysis and the survey of recent literature, it provides a quantitative basis for methane mitigation potential in China and the U.S. under carbon neutrality or net-zero pathways.
