Data Source & Methodology

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: 905.109 lb/MWh or 0.4106 kg/kWh.
