Methane (CH₄) is a major greenhouse gas (GHG) after carbon dioxide (CO₂), and coal mining and post-mining activities are the largest sources of CH₄ fugitive emissions in China. It is of great significance for China to prepare high-quality national GHG inventory and formulate targeted GHG emission control measures through the systematic study of coal’s fugitive emissions. Following 2006 IPCC Guidelines for National Greenhouse Gas Inventories, China’s 2010-2016 CH₄ emissions from coal mining and post-mining activities were calculated by tier 2 method, that is, the country-specific emission factors, and other sources by tier 1 method, that is, the default emission factors. The trend and composition of CH₄ emissions, and implied emission factors were analyzed. The results show that CH₄ emissions from China’s coal mining and post-mining activities rose first and then fell, reaching a peak in 2013, and the largest emission category was coal mining of underground mine, up to 83% of the total emissions when CH₄ recovery was not considered. The average annual increase of CH₄ recovery was 17%, the recovery rate was 27% in 2016, and the highest net emissions after deducting the recycling amount occurred in 2011. There was a large difference between the country-specific implied emission factors, and the country-specific implied emission factor of China was at the lower limit of the default values of the guidelines. The calculation of CH₄ fugitive emissions from coal mining and post-mining activities in China have reached advanced level in non-Annex I countries, but there were still some gaps in emission sources, calculation method, and country-specific emission factors compared with Annex I countries. It is recommended that in the future the integrity of the inventory should be improved, the collection of activity data should be strengthened, an in-depth research on characteristic emission factors should be conducted, and the management and technology level of CH₄ recycle from coal should be improved.
