| Summary: In this study coalbed methane use technologies that are currently available to reduce methane emissions released from coal mines are examined and methane emissions from energy production activities are analyzed. Various statistical analyses are carried out by using fugitive methane emissions of countries and composed groups. Fugitive methane emissions released from energy sector and activities constituting energy sector (natural gas and oil systems, coal mining activities, fossil fuel combustion, biomass combustion) are determined and methane emission changes between 1990 and 2020 are evaluated. This study presents global methane emissions for 1990 to 2020 for natural gas and oil systems, coal mining activities, fossil fuel combustion, biomass combustion. The energy sector is the second largest contributor (22 percent) to global emissions of methane emissions. In 1990, the energy sector accounts for 1737 MtCO2eq of methane emissions. Fugitive emissions from natural gas and oil systems are the largest source of methane emissions from this sector, accounting for 57 and 71 percent of energy related emissions in 1990 and 2020, respectively. The next largest source in this sector is fugitive emissions from coal mining, but this source has a declining share over time.Key words: Global Warming, Methane, Coalbed Methane, Coal Mining, Energy
