Grid average emission factor

Optional: factor reflecting instruments/programs

Optional

e.g., subset of sites

How to use this tool

  1. 1Enter electricity consumption for the period (kWh).
  2. 2Enter the location-based emission factor (kgCO2e per kWh).
  3. 3Optionally enter a market-based emission factor.
  4. 4Calculate and export/copy results.

What the results mean

Location-based reflects average grid emissions where electricity is consumed.

Market-based reflects the instruments/programs you claim under your method.

The tool is only as credible as your kWh dataset quality, emission factors, and documentation.

Common pitfalls

  • Using emission factors from the wrong year or geography
  • Mixing kWh periods (billing overlap)
  • Comparing market-based results without documenting instruments and boundaries
  • Treating the tool output as "final reporting" without governance and QA
