This crucially important caveat they snuck in there:
“Prof Scarborough said: “Cherry-picking data on high-impact, plant-based food or low-impact meat can obscure the clear relationship between animal-based foods and the environment.”
…which is an interesting way of saying that lines get blurry depending on the type of meat diet people had and/or the quantity vs the type of plant-based diet people had.
Takeaway from the article shouldn’t be meat=bad and vegan=good - the takeaway should be that meat can be an environmentally responsible part of a reasonable diet if done right and that it’s also possible for vegan diets to be more environmentally irresponsible.
If I source my beef or lamb from low-impact producers, could they have a lower footprint than plant-based alternatives?
The evidence suggests, no: plant-based foods emit fewer greenhouse gases than meat and dairy, regardless of how they are produced.
[…]
Plant-based protein sources – tofu, beans, peas and nuts – have the lowest carbon footprint. This is certainly true when you compare average emissions. But it’s still true when you compare the extremes: there’s not much overlap in emissions between the worst producers of plant proteins, and the best producers of meat and dairy.
Plant-based foods have a significantly smaller footprint on the environment than animal-based foods. Even the least sustainable vegetables and cereals cause less environmental harm than the lowest impact meat and dairy products [9].
