Global methane emissions are major part of the global greenhouse gas emissions. Methane in the atmosphere has a 100-year global warming potential of 34.[1]

Sources of atmospheric methane[edit]
This article is in a list format that may be better presented using prose. (April 2017) |
Biogenic (b) methane is produced by microorganisms in a process called methanogenesis. Abiogenic (a) methane stored in rocks and soil stems from ancient biomass and the generation mechanisms are not the same as for other fossil fuels.
Anthropogenic[edit]
Anthropogenic sources:[2][3][4]
- industrial agriculture (b), s.a. climate change and agriculture[5]
- coal mining (a)
- municipal solid waste (b)
- municipal wastewater (b)
- fossil fuel production (a), up to 30-45% of atmospheric methane [6]
Natural sources[edit]
Natural sources that have always been a part of the methane cycle include:[7]
- Wetland methane emissions (b)
- Aerobic methane production (b)
- Arctic methane emissions (a), (b)?
With the ongoing draining for agricultural and building areas, wetlands and the associated methane production are on the decline.
