“Supermarket chain Tesco pledged last night to revolutionise its business to become “a leader in helping to create a low-carbon economy” with a raft of new measures to help combat climate change.
In the most significant step announced yesterday, the UK’s biggest retailer, which produces 2m tonnes of carbon a year in the UK, said it would put new labels on every one of the 70,000 products it sells so that shoppers can compare carbon costs in the same way they can compare salt content and calorie counts.” Guardian
