Natural gas is odorless. The "smell" of natural gas is actually an added chemical that allows people to detect a gas leak. This chemical, called mercaptans, has a very strong smell and contributes slightly to pollution. FERC
What is natural gas?
Natural Gas is a naturally occurring mix of hydrocarbon and associated gases, mainly methane, found in geologic formations beneath the earth’s surface.
Of all the fossil fuels, natural gas produces the smallest amount of pollution when burned. Only carbon dioxide and water are released. Yet, pollutants such as carbon monoxide, nitrous oxide, sulfur, and trace chemicals may be released due to inefficiencies in the burning process.
