New York Electricity Emission Factor 2023

EPA eGRID2023 Rev2 · 3 eGRID subregions

Power plants in New York emitted 466.6 lb CO2e per MWh generated in 2023 (0.2117 kg/kWh), 39% cleaner than the US average, according to EPA's eGRID2023 state rate. Their generation was 52% carbon-free and 30% 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 York's electricity emission factor?

For Scope 2 reporting, it depends on the ZIP: New York's ZIP codes are in NYUP (242.776 lb CO2e/MWh, 75% of ZIPs), NYCW (865.744 lb CO2e/MWh, 15% of ZIPs), NYLI (1189.333 lb CO2e/MWh, 9% of ZIPs). EPA's state rate for plants in New York is 466.6 lb CO2e/MWh, 39% cleaner than the US average.

How do I calculate Scope 2 emissions for a New York 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.
