M&S invests £1m in tackling methane from burping and farting cows

Retailer works on changing diet with aim of cutting 11,000 tons of greenhouse gas emissions a year

Marks & Spencer is investing £1m in tackling the methane produced by cows by changing the diet of the herds that provide its milk.

The retailer is working with all 40 of the pasture-grazed dairy farmers in its supply base with the aim of cutting 11,000 tons of greenhouse gas emissions annually produced by cattle burps and manure. It said adding a new type of feed to the cows’ diet would reduce the carbon footprint of its main fresh milk by 8.4%.
