Consumers could soon be checking the environmental impact of food items at supermarkets through an eco-labeling system based on work by researchers at the U.K.'s Oxford University.

The researchers estimated the composition of 57,000 food products in U.K. and Irish supermarkets from public databases, and designed an algorithm to calculate an eco-score for individual products; the higher the score, the greater the environmental impact.

U.K. caterer Compass Group has worked with the researchers, and the company's Ryan Holmes said the algorithm "made us think about how we approach sustainability within the workplace" as the business seeks to realize net-zero carbon emissions by 2030.
