Which assessment tools can provide information on technology choices

The protection of the stratospheric ozone layer and climate requires the selection of technologies which differ with respect to their impacts on climate, on health, safety and other environmental endpoints and on their private and social costs. Analyses of these various impacts can assist decision-makers to choose among competing replacement technologies. However, the results of such analyses can vary, depending upon which of the many factors that are not intrinsic to the technologies are taken...

PFCs HFCs

Schematic diagram of major issues addressed by this report. Chlorofluorocarbons CFCs , halons and hydrochlorofluorocarbons HCFCs contribute to ozone depletion and climate change, while hydrofluorocarbons HFCs and perfluorocarbons PFCs contribute only to climate change and are among possible non-ozone depleting alternatives for ODSs. Red denotes gases included under the Montreal Protocol and its amendments and adjustments5 while green denotes those included under the UNFCCC and its...
