What is kilogram CO2e?

Kilogram of CO2 equivalent (kg CO2e) is the standard unit for expressing carbon footprint measurements. It quantifies greenhouse gas emissions by converting them to the equivalent warming impact of carbon dioxide over a specified timeframe.

What is watt hour CO2e equivalent?

Watt hour CO2 equivalent is a carbon emissions unit expressing the greenhouse gas equivalent of producing one watt hour of electricity. It is used in energy labelling, lifecycle assessments, and grid carbon intensity calculations.

Worked examples

1 kilogram CO2e = 2,597.4025974 watt hour CO2e equivalent

1 watt hour CO2e equivalent = 0.000385 kilogram CO2e
