During the Glasgow climate conference,the United States(U.S.)and China jointly committed to reduce methane emissions as a prioritized area of their bilateral cooperation in addressing climate change in the 2020s.Recognizing methane's strongwarming effect,which is over 80 times more potent than carbon dioxide in the first 20 years after release,reducing methane emissions is crucial to slowing down climate change in the near future[1].1 The significance of this joint commitment was reiterated in the recent U.S.-China Sunnylands Statement on Climate Cooperation,emphasizing the urgency and importance of reducing methane emissions both within each country's borders and through collaborative efforts.
