Rapeseed oil3.77kg CO₂e / kg
vs
Tofu3.16kg CO₂e / kg
Rapeseed oil or Tofu? Here's what each one costs the climate, measured per kilo over its whole life.
Rapeseed oil runs about 3.77 kg CO₂e a kilo. Tofu runs 3.16.
It's close. Rapeseed oil and Tofu land in roughly the same place.
Rapeseed oil: Pressing a whole crop into one bottle concentrates the footprint, so oils punch above their volume.
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.
