Current context: The Ministry of Environment, Forest and Climate Change (MoEFCC) has declared that India has successfully achieved the complete phase out of Hydrochlorofluorocarbon (HCFC)-141b.
a. Chlorofluorocarbons (CFCs)
b. Hydrochlorofluorocarbon (HCFC)-141b
c. carbon tetrachloride
d. Methyl chloroform
- The HCFC-141b 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.
- HCFC-141b is not produced in India and all the domestic requirements are met through imports.
- The MoEFCC prohibited the issuance of import license for HCFC-141b from 1st January, 2020 under Ozone Depleting Substances (Regulation and Control) Amendment Rules, 2019.
- With this, the country has completely phased out the important ozone depleting chemical.
- The phase out of HCFC-141b from the country has twin environmental benefits:
- Assisting the healing of the stratospheric ozone layer
- Towards the climate change mitigation
Question:
Q.1 India has recently achieved the complete phase out of which ozone depleting chemical?a. Chlorofluorocarbons (CFCs)
b. Hydrochlorofluorocarbon (HCFC)-141b
c. carbon tetrachloride
d. Methyl chloroform
