Some forty of the 119 countries that pledged last year to slash emissions of the powerful greenhouse gas methane will unveil their plans to do so at the UN climate summit next week, according to a senior U.S. official.
The outlook reflects modest progress on the U.S. and EU-led Global Methane Pledge, an international side deal to the UN climate talks in which countries promised to reduce methane emissions 30% by 2030 from 2020 levels in a bid to tackle on of the top contributors to near-term planetary warming.
