Greenhouse Gasses

Gasses which absorb and re-emit infrared radiation, thereby trapping it in Earth’s atmosphere and causing the GHG effect. They include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3).
