2022年全球甲烷控排对中国的启示

Abstract:Methane is the second most abundant greenhouse gas，accounting for 16% of global greenhouse gas emissions. In the context of global warming，methane emission control is of great significance for countries to achieve climate goals. By analyzing National Communications（NC） submitted by Annex I parties of the United Nations Framework Convention on Climate Change （UNFCCC） and the most recent Nc and Biennial Upolate Report（BUR） submitted by China，the emission status，source characteristics，policy measures，and their emission reduction effects and targets of China and abroad are systematically summarized. The main emission reduction policies and measures of main Annex I and non-Annex I parties in the energy，agriculture，and waste sector are outlined. In addition，this paper encapsulates the current situation of methane emissions and emission control policies and measures in China，reveals the potential problems of methane emission reduction practices，and proposes inspirations for methane emission control in China by comparing and analyzing international experiences. The results show that the status of methane emissions in China is consistent with global trends. In the current stage，the key technologies and management policy of methane emission control need to be improved，and the accounting and monitoring methods need to be further enhanced. While strengthening emission control，market-oriented means should be promoted to assist in methane emission mitigation.
