The US and the EU made a joint pledge on Friday to cut global methane emissions by almost a third in the next decade, in what climate experts hailed as one of the most significant steps yet towards fulfilling the Paris climate agreement.
The pledge came as the UN secretary-general, António Guterres, warned of a “high risk of failure” at the vital UN climate talks, Cop26, set for Glasgow this November.
Methane is a potent greenhouse gas, about 80 times more effective at trapping heat in the atmosphere than carbon dioxide, and emissions have been rising in recent years. Natural gas production and fracking, meat production and other forms of agriculture are among the chief sources.
The pact between the US and the EU sets a target of cutting at least 30% from global methane emissions, based on 2020 levels, by 2030. If adopted around the world, this would reduce global heating by 0.2C by the 2040s, compared with likely temperature rises by then. The world is now about 1.2C hotter now than in pre-industrial times.
