Emission Factors

Coefficients converting activity data to emissions

What is Emission Factors?

Emission factors are coefficients that quantify the emissions per unit of activity. For example, kg CO2e per kWh of electricity consumed, or per litre of diesel burned.

Why It Matters for SECR

SECR calculations rely on accurate emission factors. UK Government conversion factors are the standard for UK reporting.

Examples

  • 1

    Grid electricity: ~0.2 kg CO2e/kWh

  • 2

    Natural gas: ~0.18 kg CO2e/kWh

  • 3

    Diesel: ~2.6 kg CO2e/litre
