Power plants in Arkansas emitted 998.4 lb CO₂e per MWh generated in 2023 (0.4529 kg/kWh), 30% dirtier than the US average, according to EPA's eGRID2023 state rate. Their generation was 31% carbon-free and 8% 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 Arkansas's electricity emission factor?

For Scope 2 reporting, it depends on the ZIP: Arkansas's ZIP codes are in SRMV (741.741 lb CO₂e/MWh, 88% of ZIPs), SPSO (875.567 lb CO₂e/MWh, 11% of ZIPs), SRMW (1248.582 lb CO₂e/MWh, 1% of ZIPs). EPA's state rate for plants in Arkansas is 998.4 lb CO₂e/MWh, 30% dirtier than the US average.

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

Power plants in Arkansas generated 31% carbon-free and 8% renewable electricity in 2023. At 998 lb CO₂e/MWh, the state rate is 30% dirtier than the US average of 770.9 lb/MWh.
