Recycling methane to reduce carbon use
Methane, a greenhouse gas, is a natural by-product of a cow's digestive process. Ongoing research and innovation have helped reduce the amount of methane cows produce, while helping increase their milk production. The overall goal is to have less methane produced per litre of milk. The carbon footprint of Canada's milk production is currently 0.92 kg of CO2 per litre, which is among the lowest in the world.
