Missouri Electricity Emission Factor 2023

EPA eGRID2023 Rev2 · 4 eGRID subregions

Power plants in Missouri emitted 1454.6 lb CO2e per MWh generated in 2023 (0.6598 kg/kWh), 89% dirtier than the US average, according to EPA's eGRID2023 state rate. Their generation was 26% carbon-free and 12% 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.

How to Use Missouri's Emission Factor for Scope 2 Reporting

For GHG Protocol Scope 2 location-based emissions reporting, multiply each facility's electricity consumption by the emission factor for its ZIP code's eGRID subregion. Facilities in different parts of Missouri are in different subregions - use the API to get the exact factor by ZIP code.

Frequently Asked Questions

What is Missouri's electricity emission factor?

For Scope 2 reporting, it depends on the ZIP: Missouri's ZIP codes are in SRMW (1248.582 lb CO2e/MWh, 65% of ZIPs), SPNO (867.74 lb CO2e/MWh, 32% of ZIPs), SPSO (875.567 lb CO2e/MWh, 3% of ZIPs), SRMV (741.741 lb CO2e/MWh, 1% of ZIPs). EPA's state rate for plants in Missouri is 1454.6 lb CO2e/MWh, 89% dirtier than the US average.

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

Power plants in Missouri generated 26% carbon-free and 12% renewable electricity in 2023. At 1455 lb CO2e/MWh, the state rate is 89% dirtier than the US average of 770.9 lb/MWh.
