What is the difference between climate footprint and CO2?

  • What you measure is climate footprint and the unit with which you measure it is kg CO2e, or only kg CO2 if all the emissions are carbon dioxide (CO2). Think about it as you would with length, where what you measure is the length and the unit you measure it with is meter. If it makes grammatical sense to write length you write climate footprint and if it makes grammatical sense to write meter then you write kg CO2e.
