If we all went vegan, the world’s food-related emissions would drop by 70% by 2050 according to a recent report on food and climate in the journal Proceedings of National Academy of Sciences (PNAS). The study’s authors from Oxford University put the economic value of these emissions savings at around £440 billion.
