Enter "carbon (CO2e) footprint"
We hear about CO2 a lot — but it's not the only gas causing global warming. That's why we're changing up how we talk about greenhouse gases moving forward.
What’s the difference between CO2 and CO2e?
CO2e is a measure that was created by the United Nations' Intergovernmental Panel on Climate Change (IPCC) in order to make the effects of different greenhouse gases comparable (because every gas has a different global warming potential, remember?).
CO2e essentially describes the global warming potential of all greenhouse gases. In other words, the impact of different greenhouse gases is expressed in terms of the amount of CO2 that would result in the same amount of warming. Put simply, CO2e gathers all greenhouse gases into one place.

What is a carbon footprint?
A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions.
The average carbon footprint for a person in the United States is 16 tons, one of the highest rates in the world. Globally, the average carbon footprint is closer to 4 tons. To have the best chance of avoiding a 2℃ rise in global temperatures, the average global carbon footprint per year needs to drop to under 2 tons by 2050.
Lowering individual carbon footprints from 16 tons to 2 tons doesn’t happen overnight! By making small changes to our actions, like eating less meat, taking fewer connecting flights and line drying our clothes, we can start making a big difference.
