Since around 2015, interest for plant-based foods, in combination with concerns for animal welfare and low environmental impact, propelled consumption of oat milk.[1][2][3][4] 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.[9] Oat milk production requires 15 times less water than dairy milk and 8 times less than almond milk.[9]
