The government has issued directions prohibiting certain manufacturers from emitting a potent greenhouse gas with high global warming potential into the atmosphere, the Rajya Sabha was informed .

• “The government has issued orders on October 13, 2016 directing manufacturers of hydrochlorofluorocarbon (HCFC-22) not to emit or vent hydrofluorocarbons (HFC-23) in the atmosphere,” Environment Minister Anil Madhav Dave said . He said HFC-23 gas is a by-product of the process of manufacture of HCFC-22 gases.

• “Under the orders, the producers of HCFC-22 are mandated to file their report on production of ozone depleting substances under Ozone Depleting Substances Rules, 2000 as amended from time to time and to certify the status of HFC-23 production in each category being incinerated or used as feedstock or used for any other purpose on annual basis.

• Hydrochlorofluorocarbons (HCFCs) are compounds consisting of hydrogen, chlorine, fluorine, and carbon atoms. HCFCs and hydrofluorocarbons (HFCs) were created as substitutes for chlorofluorocarbons (CFCs) for use in refrigeration.

• All three of these classes of compounds either destroy the stratospheric ozone layer essential to life on Earth or contribute to global warming.  At a crucial climate conference on HFCs in Kigali in Rwanada recently, India had announced that it will eliminate the HFC-23 gas as part of its commitment to combat the threat emanating from climate-damaging HFCs.
