Unlocking the climate benefits of dietary substitutions: The impact of land use policy

Substituting a 100g portion of beef meatballs with pea protein "meatballs" delivers the same climate benefit as avoiding a 16 km (10 mile) drive. Conversely substituting one liter of cows' milk with soy milk will not necessarily benefit the climate directly. Nonetheless, effective land use policy could turbocharge climate benefits of simple diet substitutions, increasing climate benefits to 48 km (29 mile) and 6 km (4 mile) driving-equivalents for meatball and cow milk substitution, respectively.
