The regulation would prevent 58 million tons of methane emissions by 2038, officials said. That's about the equivalent of all the carbon dioxide emitted by American coal-fired power plants in a single year. Mr. Regan called it one of the most important policies the United States will have enacted to slow the rate of climate change over the next decade and a half.
Methane is the second most abundant greenhouse gas after carbon dioxide. It only lingers in the atmosphere about a decade after it is released, but it is about 80 times more powerful in the short term at trapping heat than carbon dioxide, which remains in the air for centuries.
