Low GWP alternative

The climate impacts of a substance is commonly expressed as the global warming potential (GWP); the lower the GWP, the more climate-friendly. The GWP values of the various HFCs or HCFCs are generally in the thousands. Conversely, GWPs of climate-friendly alternatives are much lower. The most commonly used alternatives to HFCs and HCFCs and their characteristics are listed in the table below.
