From Greenbiz.com: “Supermarket chain Tesco has labeled 20 products with information related to each product’s greenhouse gas emissions in a trial of carbon labeling. Each item is labeled with a number showing the greenhouse gas emissions per serving, Reuters reported.
The test items include orange juice, potatoes, laundry detergent and light bulbs. The company has chosen to label only a few of the tens of thousands of items it carries because of the complexity of measuring a product’s entire carbon footprint, Reuters reported. Tesco also hopes to receive consumer feedback while measuring the emissions of other products.
The labels show orange juice from concentrate has a lower carbon footprint than non-concentrate, and liquid detergent has less of an impact than powder detergent, the Daily Mail reported.” Tesco Adds Carbon Footprint to Product Labels
