Different time scale, and different form of emissions. Most of animal agriculture consider methane that are produced by cows eating grass that has grown by taking out co2 from the air. They are just as green as biofuel is green. Climate change is primary caused by humans burning fossil fuels, and humans extracting fossil fuels to be used in chemical processes like artificial fertilizers. In the short term it might be beneficial to reduce the number of animals that eat plants that has sequestrate carbon from the air, but in every case it would be worse if we humans use fossil fuel to burn the same plants. Some people has argued that in the very short term, reducing methane while increasing emissions of fossil fuel emissions could beneficial be a better strategy if we can know for sure that carbon capture will save us in the future. I am doubtful to that strategy. It should be noted that methane leaks from fossil fuel industry is larger than that from cows. A primary source of those methane leaks are the production of artificial fertilizers, but of course all steps between extracting natural gas to producing the fertilizers has large amount of emissions and leaks.
