In order to achieve the global goal of temperature rise control in the Paris Agreement，since the 21st century，many countries and regions have begun to pay attention to the strong greenhouse gas such as methane，and have made a number of methane emission reduction commitments. In terms of emissions，methane emissions account for about 10% of greenhouse gas emissions，including natural emissions and anthropogenic emissions，accounting for about 40% and 60% respectively. Among them，agriculture，the fossil fuel sector and waste sector are the main sources of anthropogenic methane emissions，and the three together account for about 95% of the total anthropogenic methane emissions. In terms of emission reduction measures，countries and regions such as Occident mainly promote methane emission reduction by formulating emission reduction targets，improving emission reduction related systems，and applying emission reduction technologies. China has started to focus on methane emission reduction at the national level in 2021. In general，methane emission reduction has become an important measure to combat climate change. At the 26th Conference of the Parties of the United Nations Framework Convention on Climate Change in 2021，105 countries around the world signed the “Global Methane Commitment” agreement，setting a target of reducing global methane emissions in 2030 by more than 30% comparing to that in 2020. In the next step，Fujian Province needs to speed up the formulation of methane emission reduction targets and action plans，establish and improve the monitoring，reporting and verification system for methane emission，and comprehensively enhance the innovation capability of methane emission reduction technologies.
