b'Air Quality Despite increased demand of our gas generation fleet due to load growth, EPE consistently maintains carbon emissions that fall below the average of the largest U.S power producers 1 . EPE ranked in the 70th percentile when comparing total CO2 emissions and CO2 rate from all generating resources. We will continue to strive towards reducing our emissions to preserve the quality of our air.1The Sustainability Institute by ERM (2024).
