Cleaner fuels will be promoted so as to bring down the pollution levels particularly in the cities… Ecological Audit of projects and pollution indexing of cities and townships will be done on scientific basis… Pollution control mechanisms will be set up on priority basis.

This entry was imported as a 2014 promise to "bring all 131 polluted cities to standard". That is not a manifesto commitment. The National Clean Air Programme was launched in January 2019, four months before the term ended, and its target list of non-attainment cities — 102 at launch, later 131, now reported as 130 — is the programme's own scope, not something the 2014 manifesto set out.

What the manifesto said about air is thinner and worth quoting exactly: "Cleaner fuels will be promoted so as to bring down the pollution levels particularly in the cities"; "Ecological Audit of projects and pollution indexing of cities and townships will be done on scientific basis"; and "Pollution control mechanisms will be set up on priority basis."

Judged on those words, one thing clearly happened. The pollution indexing of cities on a scientific basis exists — that is precisely what NCAP's non-attainment city framework and the PRANA reporting portal are. It arrived at the end of the term rather than during it, which is why delivery here is partly rather than fully recorded.

On results, the Ministry of Environment, Forest and Climate Change gave Parliament a detailed account on 23 March 2026. Money: "An amount of Rs. 14,029.23 crore has been provided since FY 2019-20 till data, as a performance based incentive and critical gap funding to 130 cities across 24 States/UTs", of which "Cities have reported the utilization of Rs. 10,611.52 crore (75.6%) on PRANA portal." City-specific clean air action plans exist for all 130 cities, targeting road dust, vehicles, waste and biomass burning, construction and industry.

On outcomes, the coarse-particle numbers are genuinely positive: "103 cities showing reduction in PM10 concentration in 2024-25 with respect to 2017-18, 64 cities have shown reduction in PM10 levels by more than 20%… and 25 of these cities have achieved a reduction of more than 40%. A total of 22 Cities have met National Ambient Air Quality Standards (NAAQS) and have PM10 Concentrations less than 60 μg/m3."

The finer particles are where the health damage is, and there the answer is weaker in a way easy to miss. "Out of the 130 cities covered under NCAP, 40 cities have shown a reduction in PM 2.5 levels in 2024 as compared to 2019; 56 cities have met the National Ambient Air Quality Standards (NAAQS) for PM2.5". Forty of 130 improving on PM2.5 is under a third, and the ministry's explanation — that "PM2.5, being a subset of PM10, is inherently addressed under NCAP through the broader regulatory framework" — is a statement of approach, not of measured effect. Note also that the two sets of figures use different baselines, 2017-18 for PM10 and 2019 for PM2.5, so they cannot be read side by side.

On cleaner fuels, the promise's other limb, this answer says nothing, and we hold no primary document measuring the air-quality effect of the fuel transitions of this period. We record that limb as untested rather than restate unsourced figures.

No CAG performance audit of NCAP has been tabled, and the utilisation figures are self-reported by cities.

A promise about indexing and priority that produced, four years late, a real programme with real money and mixed results — better on coarse dust, largely flat on the particles that matter most. Our verdict is lacks context, with the imported "131 cities" framing corrected.
