Emission factors

Emission factors describe the amount of CO2e that is emitted in the work done per activity -  per kWh, tonne km, tonne or m2 housing.

Here are some examples of emission factors:

• Petrol (242 g CO2e/kWh)
• Heat pumps for warming houses (25 g CO2e/kWh)
• Waste recycling (21 g CO2e/tonne)

The emissions can be calculated by using the Emission factor (example diesel) * Operations (number of diesel cars) * Energy intensity (of a diesel motor).
