North Carolina Electricity Emission Factor 2023

EPA eGRID2023 Rev2 · 2 eGRID subregions

Power plants in North Carolina emitted 626.4 lb CO2e per MWh generated in 2023 (0.2841 kg/kWh), 19% cleaner than the US average, according to EPA's eGRID2023 state rate. Their generation was 48% carbon-free and 14% renewable. For GHG Protocol Scope 2 location-based reporting, use the eGRID subregion factor of each facility's ZIP (below), not the state rate: power flows across state lines within a subregion.

Frequently Asked Questions

What is North Carolina's electricity emission factor?

For Scope 2 reporting, it depends on the ZIP: North Carolina's ZIP codes are in SRVC (596.326 lb CO2e/MWh, 99% of ZIPs), SRTV (903.306 lb CO2e/MWh, 1% of ZIPs). EPA's state rate for plants in North Carolina is 626.4 lb CO2e/MWh, 19% cleaner than the US average.

How do I calculate Scope 2 emissions for a North Carolina facility?

Multiply the facility's annual kWh by the kg/kWh factor of its ZIP code's eGRID subregion to get kg CO2e, and divide by 1,000 for metric tonnes. The emission factors API returns the factor for any ZIP.

How clean is North Carolina's electricity grid?

Power plants in North Carolina generated 48% carbon-free and 14% renewable electricity in 2023. At 626 lb CO2e/MWh, the state rate is 19% cleaner than the US average of 770.9 lb/MWh.
