14 October 2016 Current Affairs: India has decided to eliminate use of HFC-23, a greenhouse gas (GHG) that harms the ozone layer by 2030. With this, India, is taking the lead on tackling climate change. It was announced during the meeting of parties to the Montreal Protocol at Kigali in Rwanda. In this meeting, final negotiations are taking place to substantially reduce the use of HFCs (hydrofluorocarbons) by 2030.
The elimination will potentially check emissions of HFC-23 equivalent to 100 million tonnes of CO2 over the next 15 years. Indian companies will not be compensated for the costs involved in ensuring that these gases are not released. This move is considered as a major break away from the concept of financial assistance for every action on environment in which India earlier had shown the lead.
HFC-23 : HFC-23 is a by-product of HCFC-22 (Hydrochloroflurocarbon-22), which is used in industrial refrigeration. It is a potent greenhouse gas (GHG) with global warming potential of 14,800 times more than that of CO2.
Montreal Protocol : The Montreal Protocol, is an international treaty designed to protect the ozone layer. It came into force in 1989. It aims at reducing the production and consumption of ozone depleting substances (ODS) in order to protect the earth’s fragile ozone layer.
