What changed in CEA CO2 Baseline Database version 22.0?
Version 22.0, published August 2026, adds FY 2025-26: a weighted average of 0.675 t CO2 per MWh, down from 0.710 for FY 2024-25. It also revises FY 2024-25 using actual captive power data in place of provisional figures, and counts renewable generation in the build and combined margins.
New in version 22.0
- Data for FY 2025-26, including stations commissioned that year; decommissioned units removed.
- FY 2024-25 recalculated with actual captive power data instead of provisional data.
- Renewable generation counted in the FY 2025-26 build and combined margins.
- Database built to version 7.0 of the CDM Tool to calculate the emission factor for an electricity system.
Headline numbers, FY 2025-26
- Weighted average 0.675
- Operating margin 0.963
- Build margin 0.446
- Combined margin 0.705
- All in t CO2 per MWh, adjusted for cross-border transfers.
What to do with it
Use 0.675 for FY 2025-26 electricity in a location-based footprint. Leave earlier years on the factor for their own year unless CEA revised that year and the change is material to you.
What Senseible does here
Senseible reads electricity bills into dated kWh records per meter and site, so whichever CEA factor and version you apply, each Scope 2 figure traces back to the bill and the factor behind it.
