Which vegan milk is best for the environment?
Splashing it all over your cereal in the morning, in your tea, dare I say in your hot cocoa at bedtime, but have you thought about which one has the least environmental impact?

All of the non-dairy milks are much better for the environment than cow’s milk. They use less land, less water and generate lower amounts of greenhouse gases. The milk with the lowest greenhouse gas emissions is almond milk, because the trees lock up a lot of CO₂ as they grow. However, it does require the most water to produce of the vegan milks. Soy milk uses the least water with only slightly higher emissions.
Environmental impact of one glass (200ml) of different milks:
Emissions (kg) = 0.63
Land use (square metre) = 1.79
Water (litre) = 125.6
Emissions (kg) = 0.24
Land use (square metre) = 0.07
Water (litre) = 54
Emissions (kg) = 0.2
Land use (square metre) = 0.13
Water (litre) = 5.6
Emissions (kg) = 0.18
Land use (square metre) =0.15
Water (litre) = 9.6
Emissions (kg) = 0.14
Land use (square metre) = 0.1
Water (litre) = 74.3
- The thought experiment: What would happen if everyone on the planet suddenly went vegan?
- What would happen if a person just ate meat and nothing else?
