- Nitrous oxide, Hydrofluorocarbons (2): Nitrous oxide is a potent greenhouse gas, and hydrofluorocarbons (HFCs) are synthetic gases used in refrigeration and air conditioning that also contribute to global warming. Included under greenhouse gases.
- Carbon monoxide, Sulphur dioxide (3): Carbon monoxide is not a greenhouse gas; it is a pollutant that can affect air quality and human health. Sulphur dioxide, while a significant pollutant, is also not classified as a greenhouse gas; it contributes to acid rain and has a cooling effect on the atmosphere by forming sulfate aerosols. Not included under greenhouse gases.
- Carbon dioxide, water vapour (4): Carbon dioxide is a greenhouse gas, and water vapor is also considered a greenhouse gas as it contributes to the greenhouse effect. Included under greenhouse gases.
