Peanuts vs Tofu: carbon footprint

Peanuts or Tofu? Here's what each one costs the climate, measured per kilo over its whole life.

Peanuts runs about 3.23 kg CO₂e a kilo. Tofu runs 3.16.

It's close. Peanuts and Tofu land in roughly the same place.

Peanuts: Beans and peas fix their own nitrogen, so they dodge most fertiliser emissions. Very low.

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.
