Indian government has announced a law to eliminate HFC-23, a super greenhouse gas at a global meet in Rwandan capital Kigali. HFC-23 elimination will phase out the use of coolants that are causing climate change.
HFC-23 is a by-product of HCFC-22, which is used in refrigeration and air conditioning. This variant of hydrofluorocarbon (HFC) has a global warming potential 14,800 times more than that of carbon dioxide.
The announcement was made by India's environment minister Anil Madhav Dave, who was recently in Kigali, Rwanda, to attend a high-level meeting on the Montreal Protocol, an international treaty designed to protect the earth's ozone layer.
In a display of climate-friendly intent, India said at an international meeting this month that it has enacted a law to stop emissions of HFC-23, a gas that is thousands of times more harmful than carbon dioxide in heating up the planet.
The new Indian law requires the five Indian firms that produce HCFC-22 to capture and burn HFC-23 and eliminate its release into the atmosphere. It will potentially avoid emissions of HFC-23 equivalent to 100 million tonnes of carbon dioxide over the next 15 years.
In the recent negotiations at Kigali on phasing out HFCs, some developing countries, including China, demanded financial support from developed countries for incineration of HFC-23. However, India has now clearly said it will eliminate HFC-23 regardless of help from developed economies.
