| Methodology description | The Edison Electric Institute (EEI) Carbon Emissions and Electricity Mix Reporting Database is a voluntary reporting database developed by EEI to support corporate customers in their Scope 2 GHG accounting. It provides CO₂ emission intensity rates and resource mix information, accounting for renewable energy certificates (RECs), for delivered electricity reported at the operating company level by US electric distribution utilities. The database includes two emission intensity rates per utility. The supplier mix (utility average) emission factor is the average CO₂ lbs per MWh of all electricity delivered to customers, including all renewable generation and purchases. The residual mix emission factor is the average CO₂ rate adjusted for specified green energy products — such as green tariffs and PPAs — where renewable attributes have been retired on behalf of specific customers, ensuring those attributes are not double-counted. Both rates are aligned with the GHG Protocol Scope 2 Guidance and The Climate Registry's Electric Power Sector Protocol. Climatiq extracts both the supplier mix and residual mix emission factors from this database for specific US electricity suppliers. For full details, see the EEI database page: https://www.eei.org/issues-and-policy/national-corporate-customers/co2emissions-access. |

Cornerstone Sustainability Data Initiative
Cornerstone is a sustainability data initiative that maintains and publishes key US environmental datasets, including the US Environmentally-Extended Input-Output (USEEIO) family of models, the U.S. EPA's GHG Emission Factors Hub, and eGRID electricity emission factors, originally developed by the U.S. Environmental Protection Agency (EPA). USEEIO provides open emission factors across more than 400 sectors of the US economy and is widely used for Scope 3 corporate accounting, policy analysis, and academic research. The GHG Emission Factors Hub provides emission factors for a wide range of fuels, transportation modes, refrigerants, waste, and other activities commonly used in greenhouse gas inventories. eGRID provides detailed electricity generation emissions data for estimating the emissions intensity of grid-supplied electricity in the United States.
