The Copernicus Sentinel-5P satellite showed that the greatest methane emissions are from the tundra in Canada and Russia, and the tropics – especially the Amazonian, Central African and Indonesian wetlands. Smaller emissions were from tropical South America, north-western America, China, west Africa, Antarctica, and Cape York. 

No significant emissions were detected from the large coalfields of Europe, Canada, America, Botswana, South Africa, and Australia.
