| Methodology description | The Emissions & Generation Resource Integrated Database (eGRID) is the US EPA's comprehensive source of data on the environmental characteristics of the US electric power sector, most commonly used for estimating indirect emissions from electricity purchases, GHG inventories, and carbon footprinting of grid-supplied electricity. eGRID aggregates mass emissions and emission rates for CO₂, CH₄, N₂O, NOₓ, SO₂, and other pollutants for each electricity generating unit. Aggregated emission rates are calculated by summing emissions from all sources in a given area and dividing by total electricity generated — making them production-based rates that reflect the emissions intensity of electricity generated in that area. For carbon footprinting and GHG accounting, EPA recommends using output emission rates at the eGRID subregion level, as subregions replicate the physical constraints of the electricity grid and minimise the effect of electricity transfers between areas. eGRID also provides emission rates at state, balancing authority, NERC region, and national levels. Transmission and distribution (T&D) losses are calculated by Climatiq using the grid gross loss percentage provided by the source.
