New Jersey Electricity Emission Factor 2023

EPA eGRID2023 Rev2 · 2 eGRID subregions

Power plants in New Jersey emitted 470.2 lb CO2e per MWh generated in 2023 (0.2133 kg/kWh), 39% cleaner than the US average, according to EPA's eGRID2023 state rate. Their generation was 47% carbon-free and 3% 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 New Jersey's electricity emission factor?

For Scope 2 reporting, it depends on the ZIP: New Jersey's ZIP codes are in RFCE (599.17 lb CO2e/MWh, 99% of ZIPs), NYUP (242.776 lb CO2e/MWh, 1% of ZIPs). EPA's state rate for plants in New Jersey is 470.2 lb CO2e/MWh, 39% cleaner than the US average.

How do I calculate Scope 2 emissions for a New Jersey 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 New Jersey's electricity grid?

Power plants in New Jersey generated 47% carbon-free and 3% renewable electricity in 2023. At 470 lb CO2e/MWh, the state rate is 39% cleaner than the US average of 770.9 lb/MWh.
