What this means
Water factors cover the energy used to supply and treat water and wastewater, converting cubic metres into emissions.
Worked example
100 m³ × 0.177 kg CO₂e = 17.7 kg CO₂e ≈ 0.018 t CO₂e.
Quick conversions
1 1,000 m³ = 177 kg CO₂e (0.177 t CO₂e)
Frequently asked questions
What is the emission factor for Water supply?
The emission factor for Water supply is 0.177 kg CO₂e per m³, according to UK DEFRA (2024).
How do I use an emission factor?
Multiply your activity data (in m³) by 0.177 to get emissions in kg CO₂e, then divide by 1,000 for tonnes.
