Replacing HFCs

The focus in the climate change debate has now been shifted to the hydrofluorocarbons (HFCs) which were considered as alternatives to HCFCs (hydro chlorofluoro carbons) and other ozone depleting substances. The premise was that though HFCs have high global warming properties, they are not ozone depleting.

Now its time for the HFCs to go.

A new task force in India will now look at approaches to reduce the use of HFCs. The task force consists of Indian and American experts and recognises the challenges faced by the current phaseout of HCFCs (hydro chlorofluoro carbons) under the Montreal Protocol.

The task force, with representatives from governments and industry as well as experts in the science and technology of HFCs. It will consider options to discourage the use of HFCs and encourage the development and commercialization of alternatives with low global warming potential.

According to the members of the task force, which is scheduled to come out with a report later this year, the options will be designed to provide certainty to the business community about the future of applicable chemicals and technologies. The report will describe the status of HFC alternatives and examine policy aspects that support a global reduction in HFC use.

The report expects to inform a broader, regional meeting on HFCs and the 31st Meeting of the Open-ended Working Group of the Parties to the Montreal Protocol, scheduled in Bangkok this August.

Here’s hoping India finds better options to replace these harmful chemicals.

    We can design refrigeration and air conditioning system by using eco-friendly refrigerants such as ammonia, LiBr-water and carbon dioxide in place of HCFC and HFCs. These refrigerants have almost zero ozone depleting or global warming potential. This can save our precious planet.
