This is true in some sense but in US flying is probably most peoples' greatest carbon contribution. A single round-trip flight across the US emits about the same carbon as you save going vegan for an entire year. This is also the amount emitted by commuting a half hour to work by car 3x/week for a year.

It is definitely the case that almost everybody would have to be entirely vegan in a world that takes climate change seriously. Half-Earth Socialism did the math on this; it's a simple constraint problem.

I did some googling, not crosschecking sources, just some napkin math

Taking a passenger flight from NY to LA and back - 0.62 tons

Average american eats a 124kg of meat a year and 1 kg of beef (not counting other meats cause lazy) needs 100kg of CO2.

So a year of beef is equal to 20 roundtrips (exactly). Though the real number is probably a lot less since beef is the worst meat if you don't want CO2, then you'd need to remove the emissions from the vegan diet

Its that 100kg factoring in the CO2 that is absorbed in growing the feed? Seems way too high per kg. (Yes widespread veganism is a requirement for managing climate change though. )

Looks like it's CO2 equivalent, so it includes methane which will inflate the numbers a lot. This is a neat chart

Another thing to consider is that people get pretty upset that the Amazon is burning. No one mentions what it's being burned for though.

No omni apologists or carnists. Babystepping is for libs, and we're not here to pat you on the back. Good faith questions and debate about how to fight for animal liberation are allowed.
No advocating violence to any species for any reason. If you think this is negotiable GTFO. This includes but is not limited to animal testing, slaughter, and mass euthanasia. Anything that promotes speciesism or the commodification of animals will be removed.
