What Happened
- Delhi continues to suffer from chronic, severe air pollution intensified by widespread open burning of municipal solid waste (MSW), despite legal prohibitions under multiple environmental regulations.
- A 2023 source apportionment study by the Delhi Pollution Control Committee (DPCC) found that burning of local organic waste — including wood, cow dung cakes, agricultural waste, and refuse — contributes up to 24% of PM2.5 concentrations in winter.
- As of early 2026, Delhi's AQI hovers in the "Unhealthy" to "Very Poor" category (AQI 192–211 range), with PM2.5 levels around 100 µg/m³ — well above the WHO safe limit of 15 µg/m³ (annual mean) and India's own standard of 40 µg/m³.
- The health impact is equivalent to smoking roughly 9 cigarettes daily for every Delhi resident.
- The Commission for Air Quality Management in National Capital Region and Adjoining Areas (CAQM) has issued statutory directions mandating zero tolerance for open MSW burning, with enforcement teams deployed across NCR.
- Delhi has set deadlines for clearing legacy waste from its three landfills (Okhla: July 2026, Bhalswa: October 2026) to reduce methane-led fires at these sites.

Solid Waste Management Rules, 2016
The Solid Waste Management (SWM) Rules, 2016 replaced the Municipal Solid Wastes (Management and Handling) Rules, 2000. They mandate source segregation (wet/dry/hazardous), door-to-door collection, and scientific processing and disposal of MSW. Crucially, Rule 19(1)(b) explicitly prohibits open burning of solid waste. The rules apply to all local bodies, gram panchayats, and urban local bodies across India. Non-compliance is punishable under the Environment (Protection) Act, 1986.
- SWM Rules 2016 key mandates: Segregation at source (3-bin system: wet/dry/hazardous); door-to-door collection; ban on open burning; processing of biodegradable waste; sanitary landfill only for non-recyclable, non-combustible rejects
- Implementing bodies: Urban Local Bodies (ULBs) for collection/disposal; MoEF&CC for oversight; State Pollution Control Boards for enforcement
- SWM Gap in India: Only ~60% of MSW collected; less than 20% scientifically processed; remainder disposed in open dumps or burned
- Delhi generates ~10,500–11,000 tonnes of MSW daily; landfills at Bhalswa, Ghazipur, Okhla have all exceeded capacity
- Swachh Bharat Mission (Urban): Launched 2014; SBM 2.0 (2021): Focuses on legacy waste clearance and 100% source segregation
Connection to this news: Delhi's open waste burning persists despite SWM Rules 2016 because enforcement capacity — both manpower and technology — is inadequate relative to the scale of the problem, and the transition to scientific waste processing has been slow.
Commission for Air Quality Management (CAQM)
CAQM was established by the Commission for Air Quality Management in National Capital Region and Adjoining Areas Act, 2021, replacing earlier ad-hoc mechanisms. It is a statutory body with powers to issue binding directions to state governments and ULBs on air quality management in the NCR and adjoining areas. Its directions supersede those of state governments (except the Central Government), giving it strong enforcement teeth.
- Established: 2021; powers under CAQM Act 2021
- Jurisdiction: Delhi-NCR and the states of Haryana, Punjab, Rajasthan, and Uttar Pradesh for actions affecting NCR air quality
- Powers: Can issue directions to states/ULBs, prosecute violators, take suo motu cognizance, impose penalties
- CAQM replaced the Supreme Court-appointed EPCA (Environment Pollution (Prevention and Control) Authority)
- GRAP (Graded Response Action Plan): Implemented by CAQM; a tiered system of restrictions based on AQI levels (Stage I–IV), including bans on firecrackers, truck entry, construction
Connection to this news: CAQM's statutory directions mandating zero tolerance for open waste burning are legally binding on Delhi's civic bodies — making their non-compliance a matter of statutory default, not just policy failure.
Air Quality Standards and Health Impacts
India follows National Ambient Air Quality Standards (NAAQS) notified by CPCB under the Air (Prevention and Control of Pollution) Act, 1981. PM2.5 (particulate matter ≤2.5 micrometres) is the most health-damaging pollutant — it penetrates deep into lung tissue and enters the bloodstream. The WHO revised its Air Quality Guidelines in 2021, setting PM2.5 annual mean at 5 µg/m³ (stricter than the previous 10 µg/m³).
- India's NAAQS PM2.5 standard: 40 µg/m³ (annual mean); 60 µg/m³ (24-hour mean)
- WHO 2021 guideline: 5 µg/m³ (annual mean) — India's standard is 8× more permissive
- Delhi winter PM2.5: Regularly exceeds 200–300 µg/m³ during severe pollution events
- Sources of Delhi's PM2.5 (per DPCC source apportionment 2023): Vehicles (~28%), waste burning (~24%), dust (~20%), biomass burning (~10%), industrial (~10%), other (~8%)
- Health effects: Cardiovascular disease, lung cancer, stroke, respiratory infections; DALY (Disability-Adjusted Life Years) lost to air pollution in India among the highest globally
- Lancet Countdown India (2024): Air pollution is India's second-largest risk factor for disease burden
Connection to this news: Waste burning's ~24% contribution to winter PM2.5 makes it the second-largest identified source — larger than dust or biomass — yet it receives less regulatory attention than vehicular pollution or stubble burning, making it a critical policy gap.
Graded Response Action Plan (GRAP) and CPCB
The GRAP was developed by CPCB and implemented by CAQM for the Delhi-NCR region. It is a pre-emptive, graduated set of emergency measures triggered at specific AQI thresholds, designed to prevent pollution episodes from worsening.
- GRAP Stage I: AQI 201–300 (Poor) — ban on coal/wood in tandoors, strict vehicle pollution norms
- GRAP Stage II: AQI 301–400 (Very Poor) — ban on diesel generators (except essential services), stricter construction dust norms
- GRAP Stage III: AQI 401–450 (Severe) — BS III petrol and BS IV diesel vehicles banned in NCR
- GRAP Stage IV: AQI >450 (Severe+) — possible school closures, truck ban extended, WFH advisory
- Open waste burning: Banned under all GRAP stages
- Air Quality Early Warning System: Operated by IITM Pune, gives 3-day forecasts to trigger GRAP activations
Connection to this news: Open waste burning — which is banned under all four GRAP stages — continuing openly in Delhi represents a systemic enforcement failure that undermines the entire GRAP framework for pollution management.
