What is Global Warming Potential?
Global Warming Potential is a relative measure of how much heat a greenhouse gas traps in the atmosphere, and in turn how much the product is estimated to contribute towards global warming.
How is Global Warming Potential measured?
It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide.
A GWP is calculated over a specific time interval, commonly 20, 100 or 500 years.
