Soy milk vs Almond milk: Carbon Footprint Compared
Analyzing emissions, water usage, and land efficiency of the two most popular plant milks.
In the battle of soy milk vs almond milk, both are winners for the climate compared to dairy. However, while almond milk has a slightly lower carbon footprint (0.70kg CO2e/L), soy milk (0.98kg CO2e/L) is far more water-efficient and offers better land-use stats for the protein provided.
