National Clean Air Programme has been launched by the Central Government in the year
- (a)2018
- (b)2017
- (c)2020
- (d)2019
Correct — D, 2019. The National Clean Air Programme (NCAP) was launched on 10 January 2019 by the Ministry of Environment, Forest & Climate Change (MoEFCC). It was India's first national, time-bound framework to tackle air pollution across the country, initially covering 131 'non-attainment'/Million-Plus cities that failed to meet ambient air-quality standards, with an original target of a 20-30% reduction in PM10/PM2.5 by 2024 (base year 2017).
- (a)2018 — NCAP was announced/consulted around 2018 but was formally launched in January 2019; 2018 is a near-miss trap, not the launch year.
- (b)2017 — 2017 is the base year used for measuring the targeted PM reduction, not the launch year of the programme.
- (c)2020 — By 2020 NCAP was already a year old and being implemented; it was not launched in 2020.
NCAP is a pan-India, city-level clean-air strategy run by the MoEFCC/CPCB. Instead of a single national law, it works through city-specific action plans for 'non-attainment' cities — those whose air quality repeatedly breaches the National Ambient Air Quality Standards (NAAQS) — funding source-apportionment studies, monitoring and mitigation.
The year is easy to confuse because several dates cluster around it: 2017 (the PM base year), 2018 (draft/consultation) and 2019 (actual launch). Anchor to '10 January 2019' and the trap options fall away.
- Launched 10 January 2019 by the MoEFCC
- India's first national time-bound air-quality programme
- Initially covered 102 non-attainment cities (later expanded to 131)
- Original goal: 20-30% cut in PM10/PM2.5 by 2024 (base year 2017); later revised to ~40% by 2025-26

- Confusing the launch year (2019) with the PM base year (2017)
- Assuming NCAP is a legally binding act rather than a programme/scheme
UPPSC/UPSC ask NCAP as a straight 'launch year / launching ministry' current-affairs recall, or pair it with NAAQS/AQI concepts.

The National Clean Air Programme (NCAP) is implemented by which of the following?
- (a)Ministry of Environment, Forest & Climate Change
- (b)Ministry of Health & Family Welfare
- (c)Ministry of Road Transport & Highways
- (d)NITI Aayog
Answer(a) Ministry of Environment, Forest & Climate Change — through the CPCB.
- practice — not a real PYQ
Under NCAP, 'non-attainment cities' are those which:
- (a)fail to meet the National Ambient Air Quality Standards
- (b)have no air-quality monitoring stations
- (c)have banned all private vehicles
- (d)are located above 2,000 m altitude
Answer(a) fail to consistently meet the NAAQS.
