CO<sub>2</sub> is not the only greenhouse gas (GHG). Among others are methane (CH<sub>4</sub>) and nitrous oxide (N<sub>2</sub>O), both of which mainly come from agricultural activities. | |||

There are also fluorinated gases which are used as refrigerants (air conditioning and cold chains), fire extinguishers and in certain industrial processes and consumer goods (such as certain solvents). They are not naturally present in the atmosphere. | There are also fluorinated gases which are used as refrigerants (air conditioning and cold chains), fire extinguishers and in certain industrial processes and consumer goods (such as certain solvents).

When we talk about emissions of other GHGs, we measure them in CO2eq (CO<sub>2</sub> equivalent). This allows us to equate the emissions of other GHGs to CO<sub>2</sub> emissions on a comparable basis. We then define the Global Warming Potential (GWP) of a gas over a certain period of time. | When we talk about emissions of other GHGs, we measure them in CO2eq (CO<sub>2</sub> equivalent).
