The report states that projections for the future show that “vegan and vegetarian diets were associated with the greatest reductions in greenhouse-gas emissions.” A global shift to a plant-based diet could reduce mortality and greenhouse gases caused by food production by 10% and 70%, respectively, by 2050.
