Bread: carbon footprint per kg

Live factor value

0.776 kgCO2e per kg

Bread is one of the lower-footprint staples: the live per-kg figure below, from France's official Agribalyse database, covers wheat growing, milling, baking and distribution. Grain crops are efficient — no animal in the chain means no methane multiplier.

Wheat farming (especially fertiliser) and the energy of baking dominate the footprint; packaging and transport are minor. Even a daily-bread habit contributes only a small share of a typical food footprint.

Worked example

One 250 g baguette: 0.25 × 0.776 = 0.2 kgCO2e.

Frequently asked questions

What drives bread's carbon footprint?
Mostly fertiliser used in wheat growing and the oven energy in baking. Both are small per loaf — bread sits near the bottom of the food-footprint table.
