Colorado's electricity grid has a CO2e emission factor of 1042.5 lb/MWh (0.4729 kg/kWh) - 35% dirtier than the US average. The grid is 42% carbon-free and 42% renewable. These are the official EPA eGRID2023 values used for GHG Protocol Scope 2 location-based emissions reporting.
Colorado is entirely within the RMPA (WECC Rockies) eGRID subregion.

Colorado's EPA eGRID2023 electricity emission factor is 1042.5 lb CO2e per MWh (0.4729 kg per kWh). This is 35% dirtier than the US national average.
Multiply the facility's annual kWh consumption by 0.4729 to get kg CO2e. Divide by 1,000 for metric tonnes. For facilities spanning multiple Colorado subregions, use the emission factors API to get the exact factor by ZIP code.
Colorado's grid is 42% carbon-free and 42% renewable. At 1043 lb CO2e/MWh, it is 35% dirtier than the US average of 770.9 lb/MWh.
