I was able to find sources for your methane production figures, but can you provide them for the CO2?
To your point about increasing CO2 from farming plants: 40-66% of corn and 58%-77% of soy grown in the US is currently fed to animals, and we dedicate 5,000% more acres to growing feed crops than to vegetables[1]. Since between 3 and 10 calories of plants fed to an animal yields 1 calorie of animal product (depending on animal)[2], there would be room to either plant less, plant different, and/or use less emissive practices.
and we dedicate 5,000% more acres to growing feed crops than to vegetables
And it's worth considering what would replace all that land (maybe some would end up being biofuel production, but a lot might be allowed to return to nature if it's not profitable anymore), along with things like less demand for slash and burn.
