Climate change and meat: what's the beef?

Available for over a year

Would cutting back on meat consumption help tackle climate change? What impact would this have on individuals, governments and businesses? Livestock farming accounts for at least 14.5% of all human emissions - with beef making up the highest proportion of this. Meat free burgers are now available at fast food restaurants across the western world; veganism is on the rise, as is flexitarianism - a largely vegetable-based diet supplemented occasionally with meat. But how far can these eating trends help to reduce carbon emissions?
