GWP – Global Warming Potential
The Global Warming Potential (GWP) is a measure to compare the global warming impacts of different gases (GHG). Specifically, it is a measure of
– how much energy the emissions of 1 ton of a gas will absorb over a given period of time
– relative to the emissions of 1 ton of carbon dioxide (CO2).
The larger the GWP, the more that a given gas warms the Earth compared to CO2 over that time period. The time period usually used for GWPs is 100 years.
