The formula, explained
energy*factor/1000energy : Consumption (kWh)factor : Emission factor (gCO₂e/kWh)Your assumptions determine the result. Check your data and compare scenarios; this calculation is not a quote or a live tariff.
An example to check
Using the starting values below, the calculation gives:
An estimate tied to the emission factor — The entered energy multiplied by 50 g CO₂e/kWh gives 50 kg CO₂e.
Check the factor’s country, year and scope. Comparing a generation-only factor with a life-cycle factor can distort the comparison; this estimate covers only the entered electricity.
How to use this tool
Check the required inputs: consumption (kwh), emission factor (gco₂e/kwh).
Choose the units and options that match your task. Calculate, check the result and use Copy or Print to keep a record. Rounding applies to the display; keep more precision in intermediate steps.
Can I use a decimal comma?
Yes. Numeric fields accept 12.5 or 12,5 and spaces for thousands, such as 1 234.50. Do not mix a point and comma in one number.
