A methane leak comes from an industrial facility or pipeline and means a significant natural gas leak: the term is used for a class of methane emissions. Satellite data enables the identification of super-emitter events that produce methane plumes. Over 1,000 methane leaks of this type were found worldwide in 2022.[1] As with other gas leaks, a leak of methane is a safety hazard: coalbed methane in the form of fugitive gas emission has always been a danger to miners. Methane leaks also have a serious environmental impact. Natural gas can contain some ethane and other gases, but from both the safety and environmental point of view the methane content is the major factor.
As a greenhouse gas and climate change contributor, methane ranks second, following carbon dioxide. Fossil fuel exploration, transportation and production is responsible for about 40% of human-caused methane emissions.[1] Smaller leaks than can be spotted from space comprise a long tail of emissions. They can be identified from planes flying at 900 meters (3,000 ft).[2] According to Fatih Birol of the International Energy Agency, "Methane emissions are still far too high, especially as methane cuts are among the cheapest options to limit near-term global warming".[1]
