The really relevant thing is not the farts but 1. the CO_2 emissions for feedstuff production and transport, plus 2. the deforestation for said feedstuff production, plus 3. the insane ratio of agricultural surface requirements of plants-needed-to-feed-humans vs plants-needed-to-feed-cattle-to-feed-humans (which is approx. 1:10) For these very reasons organic meat is much better for CO_2 reduction. It doesn't use fossil fuels just to feed cattle, it limits the area foodprint of cattle production and by making meat scarcer, it last not least shifts meat based nutrition towards five-a-day nutrition.
