Remote Alaskan communities and microgrids not connected to the main grid. This page provides the official EPA eGRID2023 electricity emission factors for the AKMS subregion, used for GHG Protocol Scope 2 location-based emissions reporting.
The AKMS subregion is 32% cleaner than the US average (770.9 lb CO2e/MWh).
| Pollutant | lb / MWh | kg / kWh | Scope |
|---|---|---|---|
| CO2e (total GHG) | 522.4 | 0.2370 | Scope 2 |
| CO2 | 520.483 | 0.2361 | Scope 2 |
| CH4 (methane) | 0.026 | 0.00001179 | Scope 2 |
| N2O (nitrous oxide) | 0.004 | 0.00000181 | Scope 2 |
| NOx | 8.139 | 0.00369179 | Air quality |
| SO2 | 0.708 | 0.00032114 | Air quality |
| CO2 non-baseload | 1548.614 | 0.7024 | Scope 2 (marginal) |
Using AKMS emission factor: 522.4 lb CO2e/MWh = 0.2370 kg/kWh. Source: EPA eGRID2023.
These emission factors are from EPA eGRID2023 Rev2 (released June 2025), the official US government source for grid electricity emission rates. eGRID uses annual net generation and emissions data from all US power plants to calculate subregion-level output emission rates.
For GHG Protocol Scope 2 reporting, use the CO2e total output emission rate: 522.4 lb/MWh or 0.2370 kg/kWh.

The AKMS eGRID2023 Scope 2 location-based emission factor is 522.4 lb CO2e per MWh (0.2370 kg CO2e per kWh). This is the value to use in GHG Protocol location-based Scope 2 calculations for facilities in the ASCC Miscellaneous subregion.
The AKMS (ASCC Miscellaneous) eGRID subregion covers: AK. Remote Alaskan communities and microgrids not connected to the main grid.
Multiply kWh by 0.2370. Example: 50,000 kWh × 0.2370 = 11850 kg CO2e (11.85 tonnes).
