Greenhouse gases (GHGs)

Greenhouse gases are the chemical compounds within the earth's atmosphere which contribute to the greenhouse effect and global warming.

The most significant greenhouse gases are:

  • Water vapour (H2O)
  • Carbon dioxide (CO2)
  • Methane (CH4)
  • Ozone (O3)

Other greenhouse gases include flourinated carbon compounds such as CFCs, carbon monoxide (CO), nitrous oxide (N2O) - and many others.
