The Austin Energy system average carbon intensity is calculated as total greenhouse gas emissions at the point of combustion in pounds of CO2-equivalents divided by net generation in kilowatt-hours from all Austin Energy resources. Austin Energy generation resources include natural gas, coal and nuclear-powered units; renewable resources; and purchased power from renewable and non-renewable resources. GreenChoice® energy sales are subtracted from the net generation total since GreenChoice customers can claim their carbon intensity to be zero.

NOTE: As of 2017 the metric reported was changed to reporting lbs CO2/kWh. Years before 2017 has different metrics reported.
