India Launched Phase-out Plan of the Harmful Refrigerant HCFC

  • India launched the country’s latest plan to phase-out one of the key refrigerants l Hydrochlorofluorocarbon (HCFC)] under its ultimate goal to end use of harmful Ozone-Depleting Substances (ODS) by switching over to non-ozone depleting and low global warming potential technologies on March 7, 2017.
  • Though the fresh plan is meant for the 2017-23 period, the final goal is to phase out consumption and manufacturing of this ozone-depleting refrigerant under an accelerated plan by 2030. The HCFC is currently used in various sectors including refrigeration, air-conditioning and foam manufacturing.
