Emission factor from SLU v1.4.3
Algae Fat (Schizochytrium)
Switzerland · Cradle to farm gate · Any year
Each kilogram of this food counts as 2.52 kg CO₂e before it leaves the farm: 0.498 for raw materials and inputs, 0.622 for soil emissions, 0.997 for production energy and 0.399 for capital goods amortization.
