How to use it
- Enter electricity use for one period.
- Supply an emission factor in kg CO2e per kWh from an appropriate source.
- Choose the period label and calculate.
Electricity Emissions Calculator
Multiply electricity use by a grid emission factor that you provide.
This calculator provides rough estimates for educational purposes only. Actual emissions and savings vary by location, energy source, equipment, behavior, and calculation method. It is not regulatory, environmental audit, or professional advice.
About the Electricity Emissions Calculator
Estimate location-based electricity emissions without assuming a real-time grid value.
Formula
Estimated emissions equal electricity use in kWh multiplied by the supplied kg CO2e per kWh factor.
Example
500 kWh at 0.475 kg CO2e per kWh estimates 237.5 kg CO2e.
Notes
The tool does not retrieve live grid data. Factors vary by region, year, generation mix and accounting method.
