Potent GHG sf6 gas rapidly accumulating in atmosphere, driven by

Jul 06, 2020 · Of all the greenhouse gases regulated under the Kyoto Protocol, insulating gas is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon. In practical terms, this high GWP means that 1t of insulating gas released to the atmosphere is equivalent to the release of 23,500t of carbon dioxide (CO2).
