Who are the biggest methane emitters?
China, India, the United States, Brazil, Russia, Mexico, Ukraine, and Australia are estimated to be responsible for almost half of all anthropogenic methane emissions. The major methane emission sources for these countries vary greatly. For example, a key source of methane emissions in China is coal production, whereas Russia emits most of its methane from natural gas and oil systems. Landfills are the largest source of U.S. methane emissions.
