Are #vegan diets really the 'single biggest way' to reduce our carbon footprints & environmental impact on the planet? We argue that this is a highly misleading claim & that the evaluation of dietary change comes with a lot of context & complexity

🧐📑➡️: https://t.co/kYGeTpy8UP

1) Global data shouldn't be used to evaluate local contexts

Regional differences are important & due to very large variations in feed digestibility, slaughter age & weight, climate conditions, management, sociocultural factors, & nutrient security.

2) Further mitigation is possible

A lot of margin is left for higher productivity, feed strategies, veterinary care, smart use of manure, & herd management. A reduction of waste, the re-use of meat-processing by-products, & the valorization of biogas also hold potential.

3) Restricting animal foods only entails a small effect

For Westerners, the effect isn't only small on a yearly basis (1-6%) but especially so on a lifetime of emissions. Some vegetarians may even have higher impacts than some omnivores. Mock products do not solve the issue.

3bis) Aren't we scapegoating animal foods to downplay our non-dietary lifestyle effects?

Taking a flight, for instance, easily offsets one or more years of veganism. Yet, cars, tourism, pets, & smart phones receive little attention in comparison to the dietary quick-fix claims.
