The administration of U.S. President Joe Biden on Saturday unveiled final rules aimed at cracking down on U.S. oil and gas industry releases of methane, part of a global plan to rein in emissions that contribute to climate change.

The rules, two years in the making, were announced by U.S. officials at the United Nations COP28 climate change conference in Dubai. The United States and other nations attending the summit are expected to detail how they will achieve a 150-country pledge made two years ago to slash methane emissions by 30% from 2020 levels by 2030.

Methane tends to leak into the atmosphere undetected from drill sites, gas pipelines and other oil and gas equipment. It has more warming potential than carbon dioxide and breaks down in the atmosphere faster, so reining in methane emissions can have a more immediate impact on limiting climate change.
