Web1 de jan. de 2015 · The Kyoto Protocol, which is the most important and most prominent climate milestone to date, covers fluorinated greenhouse gases (F-gases) owing to their high global warming potential (GWP). The Global Warming Potential (GWP) is a measure of the climate effectiveness of greenhouse gases compared to CO 2 as a reference … WebIndustrial Gases. Some industrial gases have very high Global Warming Potentials (GWP). A high GWP means that an equal mass of gas causes much more global warming than CO 2 over a period of time, typically 100 years. The destruction of these gases before they are emitted is therefore a very effective way to reduce GHG emissions. WebProcess.
