Milk’s Carbon Footprint

Milk cartons in Tesco stores have some extra product information these days—the British supermarket chain has added a carbon dioxide emissions label to each pint. The emissions label displays the amount of emissions caused by its production, processing, and distribution. Tesco says that its pint of skimmed milk has a carbon footprint of 716 grams, and its whole milk has a carbon footprint of 916 grams. Now, what about the carbon footprint of its soymilk? Seeing that Tesco claims most emissions associated with milk originate from cows’ methane gas, it has to be significantly lower. Tesco, slap a carbon label on that soymilk so shoppers can compare and contrast.
