Milk3.15kg CO₂e / kg
vs
Tofu3.16kg CO₂e / kg
Milk or Tofu? Here's what each one costs the climate, measured per kilo over its whole life.
Milk runs about 3.15 kg CO₂e a kilo. Tofu runs 3.16.
It's close. Milk and Tofu land in roughly the same place.
Milk: Same cows, same methane. Milk and cheese carry it in every glass and slice.
Tofu: Tofu and soy milk hand you protein at a fraction of beef's footprint. The swap that actually moves the needle.
Per-kilo numbers skip portion size and how the food was farmed, so take them as the shape of things, not the last word.
