Carbon Dioxide (CO2)
CO2 is a colorless, odorless, non-poisonous gas that is a normal part of the ambient air. Of the six greenhouse gases normally targeted, CO2 contributes the most to human-induced global warming. Human activities such as fossil fuel combustion and deforestation have increased atmospheric concentrations of CO2 by approximately 30 percent since the industrial revolution. CO2 is the standard used to determine the “global warming potentials” (GWPs) of other gases. CO2 has been assigned a 100- year GWP of 1 (i.e., the warming effects over a 100-year time frame relative to other gases).
Carbon Dioxide (CO2) equivalent
The amount of carbon dioxide, by weight, emitted into the atmosphere that would produce the same estimated radiative forcing as a given weight of another radiatively active gas. Carbon dioxide equivalents are computed by multiplying the weight of the gas being measured (for example, methane) by its estimated global warming potential. “Carbon equivalent units” are defined as carbon dioxide equivalents multiplied by the carbon content of carbon dioxide (i.e., 12/44).

Chlorofluorocarbons (CFCs): CFCs are synthetic industrial gases composed of chlorine, fluorine, and carbon. They have been used as refrigerants, aerosol propellants, cleaning solvents and in the manufacture of plastic foam. There are no natural sources of CFCs. CFCs have an atmospheric lifetime of decades to centuries, and they have 100-year “global warming potentials” thousands of times that of CO2, depending on the gas. In addition to being greenhouse gases, CFCs also contribute to ozone depletion in the stratosphere and are controlled under the Montreal Protocol.
Clean Development Mechanism (CDM)

HGWP (High Global Warming Potential)
Some industrially produced gases such as sulfur hexafluoride (SF6), perfluorocarbons (PFCs), and hydrofluorocarbons (HFCs) have extremely high GWPs. Emissions of these gases have a much greater effect on global warming than an equal emission (by weight) of the naturally occurring gases. Most of these gases have GWPs of 1,300 – 23,900 times that of CO2. These GWPs can be compared to the GWPs of CO2, CH4, and N2O which are presently estimated to be 1, 23 and 296, respectively.

It is the term widely used to describe a family of light hydrocarbons called “gas liquids”. The most prominent members of this family are propane (C3H8) and butane (C4H10). The term “liquefied gas” may seem a contradiction in terms since all things in nature are either a liquid, a solid or a gas. Yet, it is the unique character of LPG that makes it such a popular and widely used fuel. LPG at normal temperature and pressure is a gas.

The climate system inherently attempts to balance incoming (e.g., light) and outgoing (e.g. heat) radiation. Positive radiative forcings increase the temperature of the lower atmosphere, which in turn increases temperatures at the Earth’s surface. Negative radiative forcings cool the lower atmosphere.
