(The GWPs for these gases can be in the thousands or tens of thousands.)
WebThe Global Warming Potential (GWP) metric examines each greenhouse gas’s ability to trap heat in the atmosphere compared to carbon dioxide (CO 2 ). We measure this over a specified time horizon. Often, we calculate GHG emissions in terms of how much CO 2 is essential to produce a similar warming effect over the chosen time horizon. WebGlobal warming potential (GWP) is a measurement developed to allow comparison of the global warming impacts of different gases. It is the amount of heat that a particular GHG can trap over its lifetime in the atmosphere. Carbon dioxide is assigned a GWP of 1 and is used a reference for the GWP of other GHGs. Regulatory Action
