M is for Methane Methane, the main component of fossil (so-called “natural”) gas, is about 80 times more potent in warming the atmosphere over a 20-year period than carbon dioxide. However, a 2022 investigation by Global Witness found that the plant actually emits more carbon dioxide than it captures.
