Eastern Wisconsin and Upper Michigan, served by the MISO grid. This page provides the official EPA eGRID2023 electricity emission factors for the MROE subregion, used for GHG Protocol Scope 2 location-based emissions reporting.
The MROE subregion is 82% dirtier than the US average (770.9 lb CO2e/MWh).
| Pollutant | lb / MWh | kg / kWh | Scope |
|---|---|---|---|
| CO2e (total GHG) | 1404.963 | 0.6373 | Scope 2 |
| CO2 | 1397.313 | 0.6338 | Scope 2 |
| CH4 (methane) | 0.116 | 0.00005262 | Scope 2 |
| N2O (nitrous oxide) | 0.017 | 0.00000771 | Scope 2 |
| NOx | 0.982 | 0.00044543 | Air quality |
| SO2 | 0.277 | 0.00012565 | Air quality |
| CO2 non-baseload | 1701.17 | 0.7716 | Scope 2 (marginal) |
Using MROE emission factor: 1404.963 lb CO2e/MWh = 0.6373 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: 1404.963 lb/MWh or 0.6373 kg/kWh.

The MROE eGRID2023 Scope 2 location-based emission factor is 1404.963 lb CO2e per MWh (0.6373 kg CO2e per kWh). This is the value to use in GHG Protocol location-based Scope 2 calculations for facilities in the MRO East subregion.
The MROE (MRO East) eGRID subregion covers: WI, MI. Eastern Wisconsin and Upper Michigan, served by the MISO grid.
Multiply kWh by 0.6373. Example: 50,000 kWh × 0.6373 = 31865 kg CO2e (31.86 tonnes).
