O.6. Global Warning Potential

- The Global Warming Potential (GwP) for a gas is a measure of the total energy that a gas absorbs over a particular period of time (usually 100 years), compared to carbon dioxide, lower GWP, and thus contribute more to warming Earth. Scale
- Gases with a higher GWP absorb more energy, per pound, than gases with a Methane (CH4) hasa GWP more than 20 times higher than CO2 for a 100-year time Nitrous Oxide ( N2O) has a GWP 300 times that of CO2 for a 100-year timescale
- Chloro fluoro carbons (CFCs), hydro fluoro carbons (HFCs), hydro chloro fluoro carbons (HCFCs), perfluoro carbons (PFCs), and sulfur hexafluoride (SF6) are called high-GWP
