Alaska Electricity Emission Factor 2023

EPA eGRID2023 Rev2 · 2 eGRID subregions

Power plants in Alaska emitted 814.5 lb CO2e per MWh generated in 2023 (0.3694 kg/kWh), 6% dirtier than the US average, according to EPA's eGRID2023 state rate. Their generation was 29% carbon-free and 29% 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.

Using the AKMS subregion factor (522.4 lb CO2e/MWh = 0.2370 kg/kWh), which covers 74% of Alaska's ZIP codes; for other parts of the state look up the ZIP. Source: EPA eGRID2023.

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

Frequently Asked Questions

What is Alaska's electricity emission factor?

For Scope 2 reporting, it depends on the ZIP: Alaska's ZIP codes are in AKMS (522.4 lb CO2e/MWh, 74% of ZIPs), AKGD (905.109 lb CO2e/MWh, 26% of ZIPs). EPA's state rate for plants in Alaska is 814.5 lb CO2e/MWh, 6% dirtier than the US average.

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

Power plants in Alaska generated 29% carbon-free and 29% renewable electricity in 2023. At 814 lb CO2e/MWh, the state rate is 6% dirtier than the US average of 770.9 lb/MWh.
