eGRID electricity emission factors updated to 2023, 2020 to 2023 US coverage refreshed
The Emissions & Generation Resource Integrated Database (eGRID), published by the US EPA, provides GHG data about electricity consumption emissions in the US. eGRID emission factors are essential for American companies Scope 2 accuracy, and also feed into key Scope 3 categories such as Category 11 (Use of sold products) for industries like electronics.
eGRID provides emission factors at the eGRID subregion level: 27 geographic divisions designed so that resulting emission rates most accurately reflect generation and emissions from plants within each area. Which enables highly granular US electricity accounting.
The EPA recently published the second version of the 2023 eGRID edition which we used it to update our existing 2023 eGRID electricity consumption emission factors for the US. We also took this opportunity to improve our calculation methodology and recomputed the 2020, 2021, and 2022 emission factors accordingly, ensuring all years now reflect both the latest data and a consistent, more accurate methodology. For companies reporting on 2024 or later, we recommend using the 2023 factors as the closest available proxy until the next eGRID edition is published.
