RFCW (RFC West) covers ZIP codes in OH (28%), IN (18%), WV (17%), IL (10%), PA (9%), VA (7%), WI (5%), KY (3%), MD (2%), MI (1%), by share of its ZIP codes. Its largest generation sources in 2023 were gas 38%, nuclear 28%, coal 25%. This page gives the official EPA eGRID2023 emission factors for RFCW, used for GHG Protocol Scope 2 location-based reporting.
The RFCW subregion is 19% dirtier than the US average (770.9 lb CO2e/MWh).
| Pollutant | lb / MWh | kg / kWh | Scope |
|---|---|---|---|
| CO2e (total GHG) | 916.054 | 0.4155 | Scope 2 |
| CO2 | 911.424 | 0.4134 | Scope 2 |
| CH4 (methane) | 0.071 | 0.00003221 | Scope 2 |
| N2O (nitrous oxide) | 0.01 | 0.00000454 | Scope 2 |
| NOx | 0.422 | 0.00019142 | Air quality |
| SO2 | 0.412 | 0.00018688 | Air quality |
| CO2 non-baseload | 1757.358 | 0.7971 | Avoided-emissions estimates (not Scope 2) |
Using RFCW emission factor: 916.054 lb CO2e/MWh = 0.4155 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: 916.054 lb/MWh or 0.4155 kg/kWh.

The RFCW eGRID2023 Scope 2 location-based emission factor is 916.054 lb CO2e per MWh (0.4155 kg CO2e per kWh). This is the value to use in GHG Protocol location-based Scope 2 calculations for facilities in the RFC West subregion.
RFCW (RFC West) covers ZIP codes in OH (28%), IN (18%), WV (17%), IL (10%), PA (9%), VA (7%), WI (5%), KY (3%), MD (2%), MI (1%), by share of its ZIP codes. Its largest generation sources in 2023 were gas 38%, nuclear 28%, coal 25%.
Multiply kWh by 0.4155. Example: 50,000 kWh × 0.4155 = 20775 kg CO2e (20.77 tonnes).
