 Since around 2015, interest for plant-based foods, in combination with concerns for animal welfare and low environmental impact, propelled consumption of oat milk.Compared to dairy milk and other plant-based milks, the oat milk manufacturing process produces small amounts of carbon dioxide and no methane (low greenhouse gas emissions), and requires relatively low use of water and land.Oat milk production requires 15 times less water than dairy milk and 8 times less than almond milk.
