Ahead of the 76th UN General Assembly, the US and the EU both agreed to cut methane emissions by at least 30 percent from 2020 levels by the end of the decade to reduce global warming. Will they convince other top emitters like China, Russia and India to do the same before the COP26 climate summit in November? This would be a big deal, because methane emissions, one-quarter of which come from agriculture, are the biggest contributors to climate change after carbon dioxide — and 80 times more potent in warming the planet. We take a look at the world’s top methane emitters, compared with their respective carbon dioxide emissions.
