The European Union and the United States have led a coalition of 103 countries at COP 26 in Glasgow to sign a pledge to reduce methane emissions to 70% of 2020 levels by 2030. The impact is expected to shave 0.2 degrees off the predicted temperature rise in the next decade. Methane is an extremely powerful greenhouse gas and only stays in the atmosphere for years, unlike carbon dioxide which persists for centuries. This makes it a desirable target, though it is notoriously hard to control. Over 40% of methane is emitted by natural processes such as rotting vegetation in swamps. 15% is emitted in agricultural activities, closely followed by fossil fuel production. Australia has not signed up, citing the economic impact on agriculture.
