Swachh Vayu Sarvekshan: Rankings and Policy Gaps

The Indian Express · 28 October 2026 · GS 3: Environment · 8 min read

Why in the News?

The Union government released Swachh Vayu Sarvekshan rankings in September. Despite Lucknow's PM10 reduction, its air quality remains far above national standards.

Key Highlights

• Lucknow's PM10 levels dropped from 253 to 135 micrograms per cubic metre since 2017-18.

• PM10 levels in Lucknow still exceed the national standard of 60 micrograms per cubic metre.

• Swachh Vayu Sarvekshan scores prioritize administrative activity over particulate-matter reduction, which counts for only 2.5%.

• Delhi's winter air quality showed no improvement in four years, despite GRAP measures.

• South Asia loses 10% of GDP annually due to air pollution impacts, per UNEP and CCAC.

Know the Basics

• Swachh Vayu Sarvekshan: A ranking system by the Union government evaluating cities on clean-air compliance and pollution-control measures.

• PM10: Particulate matter with a diameter of 10 micrometres or less, harmful to respiratory health.

• National Clean Air Programme (NCAP): India's policy framework for reducing air pollution through municipal action, budget allocation and programme design.

• Graded Response Action Plan (GRAP): A set of measures to control air pollution in Delhi-NCR based on pollution levels.

Detailed Analysis

Swachh Vayu Sarvekshan scoring system

• Administrative actions like road sweeping and waste management dominate the scoring criteria.

• Reduction in particulate matter contributes only 2.5% to a city's score, limiting focus on actual air quality improvement.

Economic costs of air pollution

• South Asia loses 10% of its GDP annually due to air pollution impacts, according to UNEP and CCAC.

• Investing in clean-air measures can yield ₹21 in economic and health benefits per rupee spent.

Challenges in clean-air governance

• Institutional fragmentation affects coordination among transport, industry, agriculture and other sectors.

• Assigning clean-air responsibility solely to environment departments weakens inter-agency accountability.

Impact of delayed implementation

• An eight-year delay in achieving air-quality standards halves PM2.5 exposure reduction benefits by 2040.

• Delayed measures like electric buses or pollution-control equipment cannot recover lost health and productivity.

Significance for India & UPSC Exam

• Swachh Vayu Sarvekshan shows the gap between compliance and actual air quality improvement.

• Air pollution costs South Asia 10% of GDP annually, affecting productivity and healthcare.

• UPSC could ask about NCAP, GRAP or UNEP's Hidden Assets report in GS 3 or Prelims.

• Time-bound, outcome-based governance is critical for effective pollution control.

Challenges and Way Forward

Challenges

• PM10 levels in cities like Lucknow remain far above national standards despite ranking improvements.

• Institutional fragmentation limits coordinated action across sectors like transport and industry.

• Delayed implementation permanently reduces clean-air benefits and worsens health outcomes.

Way Forward

• The Union government must prioritize outcome-based metrics in NCAP 2.0 design.

• Finance Commission should link grants to sustained pollution exposure reductions.

• Environment Ministry must strengthen inter-agency coordination for clean-air measures.

• Municipalities should focus on measurable air quality improvement, not just compliance.

UPSC Prelims Practice Question

Consider the following statements about Swachh Vayu Sarvekshan: 1. It evaluates cities based on PM10 reduction alone. 2. Lucknow's PM10 levels are below the national standard. 3. Administrative actions dominate the scoring criteria. Which of the statements given above is/are correct?

1. 1 only

2. 3 only

3. 1 and 2 only

4. 2 and 3 only

Answer: (b) 3 only

Explanation: Statement 1 is incorrect: PM10 reduction contributes only 2.5% to scores. Statement 2 is incorrect: Lucknow's PM10 is 135, above the standard of 60. Statement 3 is correct: administrative actions dominate scoring.
