Frequently asked questions
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 a 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.
There are many different greenhouse gases of which carbon dioxide is the most widely known. Different greenhouse gases affect the climate in different ways. Some stay in the atmosphere for a long time but do not cause so much warming per kg emissions, like carbon dioxide. Others, like methane, heat the earth a lot, but do not stay very long in the atmosphere. There is an exchange rate of sorts, that makes the comparison of the different gases possible. The exchange rate expresses how many kg of carbon dioxide emissions that warm the climate equally as 1 kg of another greenhouse gas. The exchange rate is called Global Warming Potential and is typically abbreviated GWP. By knowing the GWP of different gases the total climate impact of a product can be condensed into one single unit: kilograms of carbon dioxide equivalents (kg CO₂e).
