UK Government Conversion Factors
Official factors for converting energy consumption into CO2e emissions
What is UK Government Conversion Factors?
The UK Government's greenhouse gas conversion factors are official values published annually by BEIS/DESNZ. They provide the emissions factors needed to convert fuel consumption, electricity use, and other activities into tonnes of CO2e.
Why It Matters for SECR
SECR requires the use of these official conversion factors for consistency and comparability. Using out-of-date or incorrect factors is a common compliance failure.
Examples
- 1
Grid electricity: ~0.2 kg CO2e/kWh (varies yearly)
- 2
Natural gas: ~0.18 kg CO2e/kWh
- 3
Diesel: ~2.6 kg CO2e/litre
SECR Reporting Requirements
You must use the conversion factors for the reporting year. Factors are typically updated in June for the previous calendar year.
