Many greenhouse gases occur naturally in the atmosphere, such as carbon dioxide, methane, water vapor, and nitrous oxide, while others are synthetic. Those that are man-made include the chlorofluorocarbons (CFCs) , hydrofluorocarbons (HFCs) and Perfluorocarbons (PFCs), as well as sulfur hexafluoride (SF 6).
The following are the lists of the most abundant gases: 1. Nitrogen or N2 is 78.08% 2. Oxygen or O2 is 20.95% 3. Water or H2O is 0 to 4% 4. Argon or Ar is 0.93% 5. Carbon Dioxide or CO2 is 0.0360% 6. Neon or Ne is 0.0018% 7. Helium or He is 0.0005% 8.
