In an effort to tackle the low-hanging fruit of fighting climate change, President Biden and the president of the European Commission, Ursula von der Leyen, announced a joint pledge to cut methane emissions by at least 30 percent by 2030 and urged other nations to join them.
“This will not only reduce the rate of global warming, but it will also produce a very valuable side benefit, like improving public health and agricultural output,” Biden said Friday from the White House.
Methane is the second-most prevalent greenhouse gas and is 25 times more potent than carbon dioxide at trapping heat in the atmosphere. However, it also cycles out of the atmosphere much more quickly than CO2, meaning that cutting methane emissions delivers a lot more bang for the buck in the immediate future. (Methane is a major component of natural gas, but it has a much stronger warming effect when it escapes into the atmosphere than when it is burned.)

Most methane emissions come from leakage in oil and gas wells, pipelines and processing plants and they are growing rapidly because of the boom in gas and oil drilling from a process called hydraulic fracturing, or fracking.
Recent studies have found that the rate of methane leakage is much higher than originally assumed: As much as 3.7 percent of the gas being drilled is escaping. Fixing those leaks doesn’t require new technology, and it can actually save fossil fuel companies money, since they can sell the gas they don’t lose.
Earlier this month, the Environmental Protection Agency Administrator Michael Regan said his agency will propose a strict rule on methane leakage for new oil and gas wells. To meet the U.S.’s own pledge, the EPA would then have to make a rule for existing infrastructure as well.
