Why in News

The National Green Tribunal’s (NGT) South Zone Bench, Chennai, directed six southern states and UTs — Karnataka, Tamil Nadu, Kerala, Andhra Pradesh, Telangana, and Puducherry — to prepare sector-wise plans within 6 months to cut PM2.5 and PM10 levels under the National Clean Air Programme (NCAP). The order followed evidence of a severely skewed spending pattern: 86% of NCAP funds in southern states had been spent on road dust control while vehicular emissions received only 6.6% and biomass burning just 4.1% of funds — even though vehicles and biomass are the dominant pollution sources in urban India.


The NGT Order — What Was Directed

Feature Detail
Tribunal National Green Tribunal (NGT) — South Zone Bench, Chennai
Petitioner Dharmesh Shah (Chennai-based researcher; Senior Technical Advisor, Lawyers Initiative for Forest and Environment — LIFE, New Delhi)
Original petition Filed 2021; alleged failure by MoEFCC, CPCB, and southern states to implement NCAP State Action Plans
States directed Karnataka, Tamil Nadu, Kerala, Andhra Pradesh, Telangana, Puducherry
Direction Submit sector-wise plans within 6 months to cut PM2.5 and PM10 levels
Warning Fines/penalties if NCAP funds not “fully and effectively utilised”

The Problem — Skewed NCAP Spending

By September 2025, 76% of total NCAP funds released to southern states had been utilised — but the breakdown revealed a critical misallocation:

Source of Pollution Share of NCAP Funds Spent
Road dust control 86%
Vehicular emissions 6.6%
Biomass burning 4.1%
Other sources ~3.3%

The problem: Road dust is the easiest and most visible intervention — it requires sweeping machines and water tankers. But in major Indian cities, vehicular emissions and biomass burning (crop stubble, wood fuel, garbage burning) contribute far more to PM2.5 — the fine particles that penetrate the lungs and bloodstream.

Karnataka Specific Data (Confirmed)

  • Karnataka received ₹597.54 crore under NCAP between 2019–20 and 2023–24.
  • Of this, Bengaluru alone received ₹541.1 crore.
  • Yet Bengaluru had used only 13% of its allocation by October 2024 — massive non-utilisation alongside a severe air quality crisis.

About NCAP — National Clean Air Programme

Feature Detail
Full name National Clean Air Programme
Launched January 2019
Ministry Ministry of Environment, Forest and Climate Change (MoEFCC)
Cities covered 131 non-attainment cities (cities exceeding National Ambient Air Quality Standards — NAAQS — for 5+ consecutive years) across 24 states
Target (original) 20–30% reduction in PM2.5/PM10 by 2024 vs 2017 baseline
Target (revised) 40% reduction in PM10 or achieve national standard (60 µg/m³) by 2025–26
Total funds released ~₹9,650 crore (FY 2019–20 to 2023–24)
Funding mechanism Performance-based grants to cities; also via 15th Finance Commission grants
Monitoring portal PRANA (Portal for Regulation of Air-pollution in Non-Attainment cities)

State Action Plans (SAPs)

Under NCAP, each state must prepare State Action Plans identifying state-specific pollution sources and time-bound interventions across: road dust, vehicular emissions, domestic fuel combustion, industrial emissions, MSW burning, and construction dust. The NGT found southern states had not adequately prepared or implemented their SAPs.


About the NGT

Feature Detail
Full name National Green Tribunal
Established 2010 under the National Green Tribunal Act, 2010
Type Specialised quasi-judicial body for environmental disputes
Benches Principal Bench: New Delhi; Zonal Benches: Bhopal (Central), Pune (Western), Kolkata (Eastern), Chennai (Southern)
Jurisdiction Covers disputes arising from environmental laws (Environment Protection Act, Water Act, Air Act, Forest Act, Biodiversity Act)
Composition Chairperson (retd. judge, Supreme Court or HC) + Judicial Members + Expert Members
Powers Can award compensation, impose penalties, direct restoration of environment

NGT is NOT a civil court — it is a statutory tribunal with expert members (scientists, engineers) alongside judicial members.


National Ambient Air Quality Standards (NAAQS)

Pollutant NAAQS Annual Standard (India) WHO Guideline
PM2.5 40 µg/m³ 5 µg/m³
PM10 60 µg/m³ 15 µg/m³
NO₂ 40 µg/m³ 10 µg/m³
SO₂ 50 µg/m³ 40 µg/m³

India’s PM2.5 standard (40 µg/m³) is 8× higher than WHO’s guideline (5 µg/m³) — many cities still exceed even India’s own lax standard.
