6. Recently India achieved the complete phase out of one the most potent ozone depleting chemical – Hydrochlorofluorocarbon (HCFC)-141 b , discuss the impact of such a move.(250 words)
Reference: Vikas Pedia
Why this question:
India has successfully achieved the complete phase out of Hydrochlorofluorocarbon (HCFC)-141 b. Thus the question.
Key demand of the question:
Discuss in detail the positive impact of Phasing out of Ozone Depleting substances and also the challenges involved in doing so.
Discuss – This is an all-encompassing directive – you have to debate on paper by going through the details of the issues concerned by examining each one of them. You have to give reasons for both for and against arguments.
Structure of the answer:
India has successfully achieved the complete phase out of Hydrochlorofluorocarbon (HCFC)-141 b, which is a chemical used by foam manufacturing enterprises and one of the most potent ozone depleting chemical after Chlorofluorocarbons (CFCs) .(HCFC)-141 b is used mainly as a blowing agent in the production of rigid polyurethane (PU) foams.
Government of India through Ministry of Environment, Forest and Climate Change
Brought out a notification through which the issuance of import license for HCFC-141b is prohibited from 1st January 2020 under Ozone Depleting Substances (Regulation and Control) Amendment Rules, 2019 issued under Environment (Protection) Act, 1986.
Nearly 50% of the consumption of ozone depleting chemical in the country was
Attributable to HCFC-141b in the foam sector.
Discuss in detail the environmental benefits of the phase out; healing of the stratospheric ozone layer, aids climate change mitigation etc.
Explain the challenges involved in phasing out.
Conclude with way forward.
