Compare the carbon footprint of different foods, diets, and milk alternatives. From beef vs chicken to vegan vs omnivore.
Beef produces approximately 27 kg CO2e per kg — roughly 4x more than chicken (6.9 kg), 9x more than tofu (3 kg), and 30x more than lentils (0.9 kg). Per gram of protein, beef emits 5–10x more CO2 than plant-based alternatives.
For many foods, production method matters more than distance. Local is not always lower carbon than imported.
All plant milks have a significantly lower carbon footprint than dairy. Oat milk produces 0.9 kg CO2e per litre, soy 1.0 kg, almond 0.7 kg — compared to dairy at 3.2 kg CO2e per litre. However, almond milk uses significantly more water than other alternatives.
A vegan diet produces approximately 1,050 kg CO2e per year, compared to 1,400 kg for vegetarian, 1,700 kg for low-meat, 2,050 kg for average, and 2,600 kg for meat-heavy diets. Going vegan saves roughly 1,000 kg CO2e per year compared to an average diet — equivalent to not driving for 6,000 km.
