Tesco Trials Climate-Change Labels on Groceries
Tesco is trialling telling customers about the greenhouse gases emitted from "seed to store" of some products, as it hunts the green pound of customers worried about climate change. From Tuesday, the world's third-biggest food retailer is piloting carbon labelling across 20 products, putting a number on the packet showing greenhouse gas emissions per helping of certain items including potatoes, orange juice, washing-up liquid and light bulbs.
