The Latest: COP26: Countries pledge 30% methane reduction

Countries responsible for almost half the world’s methane emissions are signing a pledge to cut by at least 30% the amount of the potent greenhouse gas they release into the atmosphere over the next decade

The latest on U.N. climate summit COP26:

GLASGOW, Scotland — Countries responsible for almost half the world’s methane emissions are signing a pledge Tuesday to cut by at least 30% the amount of the potent greenhouse gas they release into the atmosphere over the next decade.

Clamping down on methane flaring and leaks from oil wells and gas pipelines is considered one of the easiest ways to cut emissions.

Cutting methane produced from agriculture — in particular by belching cows — is a trickier matter.
