A 2020 study found that, even if emissions from burning fossil fuels ended immediately, current trends in food systems could derail efforts to limit global warming to 2℃ above per-industrial levels. Some foods —such as red meat —— produce far more greenhouse gases than others. Last year, a UK government survey found that more than half the people in the country want to make more sustainable choices around food. But because many food items contain multiple ingredients, it can be difficult to unravel the environmental impact of one product over another. To create a rating system that people would find easy to understand, Clark and his colleagues used an algorithm to estimate how much of each ingredient was in thousands of products sold in major UK supermarket chains. The researchers then gave food items an environmental-impact score out of 100—with 100 being the worst—by combining the impacts of the ingredients in 100 grams of each product. They considered several factors, including greenhouse-gas emissions and land use. The team found that products containing lamb and beef—such as ready-made meat pies—had the most serious environmental impact,scoring up to three times higher than products made with poultry. The lowest-impact foods tended to be made with plants and included bread products, fruits, vegetables,grains and beverages rich in sugar. Comparing the environmental-impact score with nutritional information, the researchers found that healthier foods tended to have low environmental impacts. There were some notable exceptions:both nuts and seafood had a good nutrition score but relatively high environmental impacts. There are large differences between foods.If made more user-friendly and widely accessible, food-rating systems could help people to make informed choices about what they eat. When we start making choices, it really improves our healt
