Overview of Greenhouse Gases | Greenhouse Gas (GHG) Emissions

Concentration, or abundance, is the amount of a particular gas in the air. Larger emissions of greenhouse gases lead to higher concentrations in the atmosphere. Greenhouse gas concentrations are measured in parts per million, parts per billion, and even parts per trillion.

These are the most potent and long lasting of all greenhouse gases. They are grouped as Hydrofluorocarbons (HFCs), perfluorocarbons(PFCs), Sulphur hexafluorides(insulating gas), and nitrogen trifluoride(NF3). GWP: ranges from 7390 (PFCs) – 22800(Sulfr hexafluoride). Small quantities of these gases are sufficient to increase the greenhouse effect multi-fold.

What gases are greenhouse gases? – Jean-Marc Jancovici

Aug 01, 2007 · The definition of a greenhouse gas is at the same time very simple and very complicated for the ordinary man (or woman !) : such a gaz is “just” a gas mixed in the atmosphere that absorbs the infrared radiation emitted by the earth’s surface. We are not accustomed to these gases because neither nitrogen nor oxygen, the two most abundant
