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.

India on Tuesday unveiled its roadmap for phasing out hydrochlorofluorocarbons (HCFC) by 2030 under the Montreal Protocol even as it sought the requisite technology and funds for it from the global community.

India will phase out hydrochlorofluorocarbons (HCFCs), used for refrigeration and air-conditioning, by 2030 in line with the Montreal Protocol, a treaty to protect the ozone layer.

The consumption of HCFCs has grown at an average annual rate of over 11.3 per cent in the past 15 years
ndia will phase out hydrochlorofluorocarbons (HCFCs) by the year 2030.
These chemicals are widely used in refrigeration and airconditioning systems and are major cause of global warming.
