What this means
Electricity factors convert kilowatt-hours of purchased grid power into emissions. Because every grid mixes different generation sources, the factor depends heavily on the country and the year — always use a location-based factor for your own market.
Worked example
1,000 kWh × 0.37 kg CO₂e = 370 kg CO₂e ≈ 0.37 t CO₂e.
Quick conversions
1 MWh = 370 kg CO₂e (0.37 t CO₂e)

Frequently asked questions
What is the emission factor for Grid electricity?
The emission factor for Grid electricity is 0.37 kg CO₂e per kWh, according to US EPA eGRID (2022).
How do I use an emission factor?
Multiply your activity data (in kWh) by 0.37 to get emissions in kg CO₂e, then divide by 1,000 for tonnes.
