According to the UN Food and Agriculture Organisation (FAO), the livestock industry is responsible for 15% of all human-induced greenhouse gase (GHG) emissions globally. Cows form the majority of these GHGs by emitting large amounts of methane each day from their inefficient digestive system (i.e. burps and flatulence). In fact, one cow produces on average 2.4Tons CO2e per year. This is more than the amount of CO2 emissions of an average car used for a year.
