Why is cow's milk rated the same as dairy-free alternatives, even though cows have a large environmental impact?
Several cow’s milk options typically have a score of B, similar to dairy-free alternatives that are usually rated A or B. The reason cow's milk is not as bad for the environment as beef, which is rated G, is because of the quantity produced. Cows produce much more milk compared to the amount of beef they produce. Therefore, the environmental impact per kilogram of milk is lower than the impact per kilogram of beef, due to the large difference in the quantities of milk versus beef produced, which affects how the impact is calculated.
