Scores of countries have joined a pledge to cut their methane emissions by 30% by the end of the decade as part of efforts to tackle climate change.

The global methane pledge, led by the US and EU, has been formally launched at the Cop26 climate summit in Glasgow, where countries are under pressure to increase their emissions cuts to avoid dangerous warming beyond 1.5C.
