This briefing illustrates how HFC-23 projects under the CDM are working directly against the objectives of the UNFCCC and the Montreal Protocol, which is working to phase out HCFCs. HFC-23 emissions are clearly best addressed through direct measures outside the CDM.

The Montreal Protocol is at a crossroads in its efforts to restore Earth

The attractions of a piecemeal approach to global warming

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.

Focuses on the issue of phasing down hydrofluorocarbon (HFC) use. It also provides a summary of the UN DPI non-governmental organization briefing on the ozone layer and climate change held on 18 June 2009, including presentations as well as the question and answer session held with ozone experts.
