Nearly 90 countries join pact to slash planet-warming methane emissions

(Reuters, 2 Nov 2021) The Global Methane Pledge now includes half of the top 30 methane emitters accounting for two-thirds of the global economy - including new signatory Brazil.

Nearly 90 countries have joined a U.S.- and EU-led effort to slash emissions of the potent greenhouse gas methane 30% by 2030 from 2020 levels, a pact aimed at tackling one of the main causes of climate change, a senior Biden administration official said.

The partnership will be formally launched later on Tuesday.

Methane is the main greenhouse gas after carbon dioxide. It has a higher heat-trapping potential than CO2 but breaks down in the atmosphere faster - meaning that cutting methane emissions can have a rapid impact on reining in global warming.

The Global Methane Pledge, which was first announced in September, now includes half of the top 30 methane emitters accounting for two-thirds of the global economy, according to the Biden administration official.

Among the new signatories that will be announced on Tuesday is Brazil - one of the world's five biggest emitters of methane.
