What this means
Waste factors convert the mass of waste, by treatment route (landfill, recycling, composting), into emissions. The treatment method usually matters far more than the material alone.
Worked example
100 kg × 0.021 kg CO₂e = 2.1 kg CO₂e ≈ 0.002 t CO₂e.
Quick conversions
1 t = 21 kg CO₂e (0.021 t CO₂e)
