GS Paper - 3 (Environment)

The government imposed curbs on exports of hydrofluorocarbons, used in refrigeration and air-conditioning, to boost domestic availability of the chemical. Exporters will now have to seek permission from the government to export hydrofluorocarbons (HFCs).

What

  1. Export policy of hydrofluorocarbons has been revised from free to restricted category with immediate effect, and export authorisations would be issued on NOC (No Objection Certificate) from MoEF and CC (Ministry of Environment, Forest and Climate Change).
  2. The move assumes significance as the government has extended a Rs 6,238-crore PLI (Production-Linked Incentive) scheme for white goods to boost the manufacturing of components and sub-assemblies of ACs and LED lights.
  3. Earlier this month, the government had imposed similar curbs on imports of HFCs.
  4. Hydrofluorocarbons (HFCs) are a group of industrial chemicals primarily used for cooling and refrigeration.
  5. HFCs were developed to replace stratospheric ozone-depleting substances that are currently being phased out under the Montreal Protocol on Substances that Deplete the Ozone Layer.
  6. Many HFCs are very powerful greenhouse gases and a substantial number are short-lived climate pollutants with a lifetime of between 15 and 29 years in the atmosphere.
