Methane emissions from 15 of world's biggest meat and dairy firms exceed individual countries

Beef and dairy cattle are among the biggest contributors to greenhouse gas emissions, with cows mainly generating methane through digestion and waste.

The combined methane emissions from the 15 of the world's biggest meat and dairy firms such as Nestlé and Danone exceed those of countries like Russia, Canada, Australia, or Germany.

That is according to a study from sustainable production organisations, the Institute for Agriculture and Trade Policy and the Changing Markets Foundation, which unveiled the findings as negotiations intensified at the Cop27 climate change summit in Egypt.
