Power plants in Mississippi emitted 828.3 lb CO₂e per MWh generated in 2023 (0.3757 kg/kWh), 7% dirtier than the US average, according to EPA's eGRID2023 state rate. Their generation was 19% 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.

How to Use Mississippi'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 Mississippi are in different subregions - use the API to get the exact factor by ZIP code.

Frequently Asked Questions

What is Mississippi's electricity emission factor?

For Scope 2 reporting, it depends on the ZIP: Mississippi's ZIP codes are in SRMV (741.741 lb CO₂e/MWh, 42% of ZIPs), SRTV (903.306 lb CO₂e/MWh, 35% of ZIPs), SRSO (846.007 lb CO₂e/MWh, 23% of ZIPs). EPA's state rate for plants in Mississippi is 828.3 lb CO₂e/MWh, 7% dirtier than the US average.

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

Power plants in Mississippi generated 19% carbon-free and 3% renewable electricity in 2023. At 828 lb CO₂e/MWh, the state rate is 7% dirtier than the US average of 770.9 lb/MWh.
