Study Notes
Montreal Protocol and Ozone Layer Depletion
- The 1991 eruption of Mt. Pinatubo in the Philippines led to significant ozone loss in the stratosphere.
India's Achievement under Montreal Protocol
- India surpassed the Montreal Protocol targets, reducing HCFC (Hydrochlorofluorocarbons) by 44% from the 2020 baseline, exceeding the 35% phase-out goal.
- Eliminated HCFC 141b, used as a blowing agent in rigid polyurethane foam production.
- Will completely phase out HCFC use in new equipment manufacturing by December 2024, ahead of the Montreal Protocol schedule (2030).
Other Achievements of India
- Phased out CFC, Carbon tetrachloride, Halons, and other controlled uses.
- Implementing HFCs Phase-out Management Plan (HPMP) Stage- II from 2017 to 2024.
- India Cooling Action Plan (ICAP) aims to reduce cooling demand, refrigerant transition, enhance energy efficiency, and adopt better technology options by 2037-38.
Montreal Protocol (1987)
- Implemented under the Vienna Convention (adopted in 1985).
- A global environmental treaty to eliminate Ozone Depleting Substances (ODS) production and use.
- World Ozone Day is celebrated on September 16th each year to commemorate its signing.
Kigali Amendment to Montreal Protocol
- Adopted in 2016 and entered into force in 2019.
- Aims to phase down production and consumption of Hydrofluorocarbons (HFCs), non-ODS alternatives to CFCs and HCFCs.
- Divides nations into three groups with a four-step path to achieve 80% reduction in HFCs consumption by 2047.
India and Montreal Protocol
- Became a Party to the Vienna Convention in 1991 and the Montreal Protocol in 1992.
- Implementing agency: Ministry of Environment, Forest and Climate Change (MoEF&CC).
- Ratified the Kigali Amendment in 2021, committing to complete its phase down of HFCs in four steps from 2032 onwards.
