Number of countries, as of Monday, that have pledged to reduce their total methane emissions 30% by 2030.
Methane is the second most prevalent greenhouse gas after carbon dioxide, but it’s massively more potent (at least in the short-term) when it comes to heating the planet.
China, India, Russia, and Brazil have not signed on to this pledge, and they’re four of the heaviest emitters of this and other such gases. But we’re just a few weeks out from the next international climate conference, so those (and other) countries might join this pledge or announce their own (potentially even better) pledge in the coming weeks.
