How Carbon Emissions are Calculated for Electricity Usage
Electricity carbon emissions depend on how much power you use and how that power is generated.
To estimate your footprint, multiply your monthly kilowatt-hours by an emission factor, which represents the average kilograms of CO2 released per kWh on your local grid.
In the United States, that factor typically sits around 0.4 kg CO2 per kWh, though it varies by region depending on the mix of coal, natural gas, nuclear, and renewables.
This calculator uses your usage and cost inputs to approximate total emissions, then compares that figure against the sequestration potential of the trees you plan to plant for a clearer offset picture.
