In 2024, India successfully eliminated hydrochlorofluorocarbons (HCFCs) from its manufacturing processes, fulfilling its obligations under the Montreal Protocol. This landmark achievement strengthens global efforts to protect the ozone layer and mitigate climate change, while underscoring India’s commitment to sustainable environmental practices.

Montreal Protocol: A Global Success Story

• Established: 1987, came into effect in 1989.
• Objective: To phase out substances that deplete the ozone layer.
• Achievements: Since 1990, 98% of ozone-depleting substances have been eliminated globally.
• Future Goal: The ozone layer is projected to recover by the mid-21st century, thanks to the protocol’s enforcement.

HCFCs and Their Phase-Out

• What are HCFCs?
  • Chemical compounds primarily used in refrigeration and air conditioning.
  • Introduced as temporary substitutes for chlorofluorocarbons (CFCs) but still harmful to the ozone layer.
• Accelerated Phase-Out:
  • The 1992 Copenhagen Amendment expedited HCFC phase-out globally.
  • India’s 2024 ban marks a significant milestone in this effort.

India’s Environmental Commitments

• Global Alignment:
  • India joined the Vienna Convention in 1991 and the Montreal Protocol in 1992.
  • It implemented a phased strategy to eliminate ozone-depleting substances, achieving reductions as early as 2010.
• Recent Milestone:
  • The 2024 HCFC phase-out is part of a broader strategy to address both ozone protection and climate change.

Transitioning to HFCs and the Kigali Amendment

• What are HFCs?
  • Alternatives to CFCs and HCFCs, these greenhouse gases do not harm the ozone layer but significantly contribute to global warming.
• Kigali Amendment (2016):
  • Aims to reduce HFC use by 85% by 2036 for developed countries and by 2047 for developing nations.
  • India is committed to limiting HFC use, reflecting its dedication to combating climate change.

Innovations in Cooling Technologies

• Discussions at COP 2024:
  • Focused on sustainable cooling solutions, including solar cooling and evaporative cooling.
• Global Negotiations:
  • Emphasis on natural refrigerants and effective refrigerant management to reduce environmental impacts.

India’s Future Plans for Cooling and Sustainability

• Complete HCFC Phase-Out by 2030:
  • India aims to eliminate HCFCs entirely within the next decade.
• Reducing HFC Use:
  • India has set specific reduction targets for HFCs, aligning with global environmental goals.
• Focus on Innovation:
  • Developing energy-efficient cooling technologies and minimizing refrigerant leakage to support a greener future.

India’s successful HCFC phase-out not only reaffirms its commitment to the Montreal Protocol but also highlights its proactive role in addressing climate change. The country’s focus on sustainable technologies and international cooperation paves the way for a more environmentally secure future.
