Beef vs Eggs: carbon footprint

Beef99.48kg CO₂e / kg
vs
Eggs4.67kg CO₂e / kg

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

Beef runs about 99.48 kg CO₂e a kilo. Eggs runs 4.67.

Beef is the heavier choice, about 21× Eggs.

Swap Beef for Eggs and you cut about 94.81 kg a kilo, near 95% off.

Per kilo, that gap is a 555 km drive in a diesel car.

Beef: Cows and sheep burp methane and need a lot of land and feed, which is why red meat towers over everything else here.

Eggs: Middling. Hens eat feed, but there's no methane belch, so eggs sit well below beef.

Per-kilo numbers skip portion size and how the food was farmed, so take them as the shape of things, not the last word.
