CAC - carbon monoxide, nitrogen oxides, particulate matter, sulfur oxides and volatile organic compounds-are a group of chemicals associated with environmental effects such as smog, acid rain and regional haze, and health effects such as respiratory illnesses. Major sources of CACs are the burning of fossil fuels, as well as natural resource extraction and a variety of manufacturing activities.
GHG - contribute to climate change by trapping heat within the earth's atmosphere. GHGs are the subject of the international Kyoto Protocol, which came into force in 2005. The major gases include carbon dioxide, methane, nitrous oxide and three groups of fluorinated gases.
