Frequently Asked Questions

Why beef so high?
Cattle = methane-emitting. ~27 kg CO2-eq per kg beef (vs chicken 6, pork 7, lentils 0.9). Per typical 200g serving: beef ~5kg, chicken ~1.2kg, lentils ~0.18kg. 25× difference per meal.
Is local beef better?
Marginal. Production emissions dwarf transport — cow methane, feed, land-use change. Local beef ~10% better than imported. Chicken or plants ~80-90% better.
Dairy + cheese?
Dairy emissions roughly match chicken per kg protein. Cheese is calorie-dense so per-meal can be ~2-3 kg CO2 (substantial). Plant-based alternatives dramatically lower.
