More than 100 nations pledge to cut emissions of methane by 30 percent this decade, in the most significant climate commitment so far at COP26 climate summit
Dozens of countries have joined a United States and European Union pledge to cut emissions of methane, the most potent greenhouse gas, by 30 percent this decade, in the most significant climate commitment so far at COP26.
He called the pledge, which has so far been signed by more than 100 nations, a "game-changing commitment" that covered countries responsible for around half of global methane emissions. Decades of climate pledges have been rooted in reducing carbon dioxide emissions. Yet methane is more than 80 times more potent than CO2, and its sources, such as open pit coal mines and livestock, have received relatively little attention until now.
This would shave 0.3C off projected warming, save a quarter of a million air pollution deaths and increase global crop yields by 26 million tonnes, the UN's Environment Programme said.
