Prelims Trap

Swachh Vayu Survekshan is implemented by the Ministry of Housing and Urban Affairs (MoHUA).

Aspirants often confuse Swachh Vayu Survekshan (administered by MoEFCC for air quality under NCAP) with Swachh Survekshan (administered by the Ministry of Housing and Urban Affairs for solid waste and sanitation).

Static Concepts Connected

Environment and Ecology - Pollution and Control

What are the primary goals and institutional mechanisms of the National Clean Air Programme (NCAP) in India?

  • Target Reductions: Target reduction of 20-30% in PM2.5 and PM10 concentrations by 2024 (baseline 2017), later revised up to 40% reduction by 2026.
  • Nodal Agency: Implemented by the Central Pollution Control Board (CPCB) under the Ministry of Environment, Forest and Climate Change (MoEFCC).
  • Non-Attainment Cities: Covers over 130 non-attainment cities that fail to meet national ambient air quality standards across India.

Cross-Topic Patterns

  • NCAP + Municipal Finance Devolution

    NCAP targets link urban air quality management with fiscal devolution and municipal governance reforms under the 15th Finance Commission grants for million-plus cities.

  • Urban Air Pollution + NGT Mandates

    West Bengal industrial clusters and Kolkata transport corridors highlight the policy trade-off between rapid urbanization and statutory environmental compliance under the NGT.
