I'm pretty sure that's wrong or the wrong data point. Livestock is the largest source of methane emissions and methane plays a larger role in climate change.
Not to mention that eating less meat is just karmically/ethically way more optimal, regardless of what the data says.
Note that there is a difference between methane and carbon. My quote only mentioned carbon.
> The most important greenhouse gases from animal agriculture are methane and nitrous oxide. Methane, mainly produced by enteric fermentation and manure storage, is a gas which has an effect on global warming 28 times higher than carbon dioxide. Nitrous oxide, arising from manure storage and the use of organic/inorganic fertilizers, is a molecule with a global warming potential 265 times higher than carbon dioxide.
Additionally, he missed the fact that deforestation has other negative impacts besides contributing to climate change.
All things considered, meat consumption is pretty much the main reason for the destruction of Amazonian rainforest, using up incredible amounts of land, food, and water, as well as producing a statistically significant amount of pollution. Then there is desertification, MDR pathogens, and so forth.
