In a previous article I looked at where greenhouse gas (GHG) emissions in the food system came from – ranging from deforestation and land use, through to transport and packaging. The study my article was based on was published by Joseph Poore and Thomas Nemecek, estimated that the food system was responsible for one-quarter (26%) of global emissions.1 A new study, published by Monica Crippa and colleagues in Nature Food estimates a higher share: one-third (34%) of emissions.
Edit: and another source, since that quote is about food writ large:
Given that the climate impact of plant-based foods is typically 10 to 50 times smaller than that of animal products, it follows that switching from a largely meat-based diet to a vegetarian or vegan diet could help to reduce emissions.
first, I wouldn’t trust poore/nemecek 2018 to tell me how much a cc of water weighs. but even if we take your quote as gospel,.there is no reason to believe that lab grown meat would eliminate all GHG emissions.
you said lab grown meat would reduce our ghg emissions by 30% then quoted a pair of studies, one of which is dubious imho, that placed the entire ghg emissions of all of agriculture around 30%.
I don’t know why you’re so obsessively in the weeds on this. Numbers do vary depending on the source, but meat farming is unequivocally an ecological disaster.

So assuming the low 10% figure we can remove 3.4% from the previous number, giving 30.6%

Sure is a good thing I never said that, then, because that would indeed be a ridiculous claim.

Of farming specifically, the overwhelming majority of which is used to feed livestock.
you’re clarifying that now, but it’s neither what you said nor supported by the data you provided. further, this claim
just isn’t true. about 1/3 of global crop calories go to livestock, but even those calories are often parts of plants that people can’t or won’t eat.

Anyway I’m done, anything beyond this is simply in bad faith.
