An unparalleled opportunity for Copenhagen eliminate HFCs

Halogenated gases currently contribute 12% to overall radiative forcing. While actions under the Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol) are already addressing CFCs and HCFCs, atmospheric concentrations of some HFCs (hydrofluorocarbons) are rising rapidly, by more than 23% each year. A global agreement to phase …
