Environment Minister Anil Dave has said India will no longer permit the release of HFC-23, a family of potent greenhouse gases, released when local companies produce the refrigerant HCFC-22.
Mr. Dave is at Kigali, Rwanda, in the midst of thrashing out a deal with the developed countries to amend the Montreal Protocol, a 1987 agreement whereby countries have agreed to limit the emission of gases that destroy the ozone layer.
The latest amendment is to discuss the phasing out of hydrofluorocarbons (HFCs, of which HFC-23 is one), only beginning to be used in India and still used in the developed countries and once a replacement for the ozone-destroying gases. Over the years, HFCs were found to be exacerbating global warming.
The Kigali talks will also discuss the years by which the developing and the developed countries will cap HFC emissions and switch to a new suite of gases that cause less global warming and become the mainstay of home and car air-conditioners and industrial cooling solutions.
