Ghg with highest gwp
Global warming potential (GWP) is the heat absorbed by any greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of carbon dioxide (CO2). GWP is 1 for CO2. For other gases it depends on the gas and the time frame. Carbon dioxide equivalent (CO2e or CO2eq or CO2-e) is calculated from GWP. For any gas, it is the mass of CO2 that would warm the earth as much as the mass of that gas. Thus it provides … Web27 rows · Greenhouse Gas Data Frequently Asked Questions Global Warming Potentials …

WebOct 6, 2016 · The GWP of SF 6 is 22,800, making it the most potent greenhouse gas that the Intergovernmental Panel on Climate Change has evaluated. To find out more about the role of fluorinated gases in warming the atmosphere, and their sources, visit the Causes of Climate Change page and the Climate Change Indicators page in the Science section. WebSep 27, 2024 · Global warming potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere up to a specific time horizon, relative to carbon dioxide. It compares the amount of heat trapped by a certain mass of the gas to the amount of heat trapped by a similar mass of carbon dioxide.
