“The more aggressive the temperature goal, the more important potent, short-lived greenhouse gases such as methane become,” says Rob Jackson, professor of energy and environment at Stanford University. In a new analysis with Abernethy, Jackson calculates that measured on a timeframe to the mid-2040s — the likely deadline for capping warming under the Paris Agreement — methane is three times more important than assumed under existing regulations.

“We are severely undervaluing methane,” says Abernethy. “We need drastic climate action in the short term to achieve our Paris Agreement goals. Methane is the best lever to make that happen.”

This will require action against not just leaks from oil and gas infrastructure, but also the many biogenic sources, such as landfills and livestock. But achieving that is being undermined by what Abernethy calls the “arbitrary and unjustified” timeframe under which regulators currently assess the gas.
