Rapid global phaseout of animal agriculture has the potential to stabilize greenhouse gas levels for 30 years and offset 68 percent of CO2 emissions this century

Impact of dietary transitions in curtailing global warming.

Using projected CH4 and N2O levels in 2100 under business as usual diet as a baseline for RF calculation, we computed the CO2 reductions necessary to reduce RF from the business as usual diet level of RF = 1.31 to the bovid-free diet level of RF = 4.09 (1300 Gt CO2), the plant-only diet level of RF = 3.83 (1680 Gt CO2), the 2.0° C global warming target of RF = 2.6 (3230 Gt CO2) and the 1.5° C global warming target of RF = 1.9 (3980 Gt CO2). For this analysis we used a corrected RF that accounts for the absence of other gases in our calculation by training a linear regression model on published MAGICC6 output to estimate from CO2, CH4 and N2O levels the residual RF impact of other gases.
