this is warmed-over poore-nemecek 2018. that's the primary basis for the claims about the climate, but the methodology of that study is fucked, and it's a disservice to actual climate science to keep touting this meta"study" that misuses its source material and myopically focuses on distilling data instead of understanding the complexity of our agricultural systems. the textile industry's water use, land use, and emissions, i guarantee, are being counted in poore-nemecek as emissions from beef. i didn't pull out the data from the separate reference to water use, but i will eat my hat if that doesn't, as well.
eating less beef has not been effective at stopping the growth of the beef industry for all the people who have done so. we need a real solution, and trying to influence individual consumer choice isn't working.
edit: down voting doesn't change the truth
