This week at the COP, the Biden administration announced a broad methane initiative, which includes new draft Environmental Protection Agency regulations tightening up methane leaks in the oil and gas industry and additional actions by agencies across the federal government. These developments should make a real difference. But even with a greater focus on emissions reductions, some methane emissions, particularly in food production, will be difficult to eliminate. Natural sources of methane could even increase in the coming decades as wetlands warm and Arctic permafrost thaws. So in addition to cutting methane emissions, we need ways to remove methane from the atmosphere, too.
