How do I complain about air pollution or noise from a neighbour or factory in India?

Where you file a pollution complaint depends on what you are dealing with. For most air, water, noise and industrial pollution, the State Pollution Control Board (SPCB) is the starting point — every state accepts complaints through its online portal, by email to the regional office, or as a walk-in. Attach photos, videos with timestamps, and any witness statements you can gather. For air quality specifically, CPCB's SAMEER portal takes nationwide complaints and lets you attach PM2.5 / PM10 readings.

Localised nuisances — construction debris, waste burning, restaurant chimneys, small factories inside municipal limits — usually move faster through the Municipal Corporation. If the pollution amounts to a criminal nuisance, an FIR under Section 270 BNS (public nuisance — 6 months imprisonment or fine) or Section 296 BNS (annoyance in public way) is available, and police can act on serious cases without waiting for regulators.

When regulators fail to act, or the violation is systemic, escalate to the National Green Tribunal by original application (₹1,000 filing fee) or to the High Court under Article 21, which the Supreme Court has repeatedly read to include a right to a clean environment. Document everything — AQI app readings, timestamped photos, medical records showing health impact, property damage — because pollution cases rise or fall on evidence.

Common sources have specific channels: construction dust to the Municipal Corporation under CAQM guidelines; restaurant emissions jointly to SPCB, fire and municipal; factory emissions to SPCB and the Pollution Control Committee; vehicle emissions via the Transport Department and RTO through PUC enforcement; waste burning to municipal and police (banned under the Solid Waste Management Rules); diesel generators to SPCB against CPCB norms. Keep the reference number and escalate to the next authority if there is no action in a reasonable time.

India's noise pollution regime works on zone-based day and night limits — residential, commercial, industrial, and silence zones each have their own decibel caps, with lower limits between 10 PM and 6 AM. Beyond the numbers, the enforcement fight is usually about exceptions.

Religious and cultural events can use loudspeakers with prior permission, but the 10 PM cut-off — sometimes extended by state notification during festivals — still applies. Weddings and celebrations need police permission, are usually time-bound to 11 PM, and often require a society NOC. Construction noise is confined to daytime in most cities, with heavy work banned at night. Vehicle horns are banned outright in silence zones and pressure horns are illegal under CMVR Rule 119, and external audio from car music systems is capped as well.

Neighbourhood irritants — barking dogs, air conditioners, compressor units, DJ systems — usually fall into civil nuisance territory. Society or RWA mediation resolves most cases; police involvement is a last resort. Reasonable everyday sound (children playing, brief cultural events) is generally tolerated by courts.

For evidence, a basic sound level meter costs ₹2,000-₹15,000; mobile apps like Sound Meter or Decibel X give approximate but useful readings; and SPCB will send a professional measurement team when you complain. For contested legal proceedings, get an acoustic consultant's report.

The framework rests on the Supreme Court's directions in Noise Pollution (V), In re, (2005) 5 SCC 733 and Forum, Prevention of Envn. & Sound Pollution v. Union of India, both of which banned loudspeakers after 10 PM and treated religious extensions as narrow, state-notified exceptions. Local police stations, the 100 helpline, and dedicated noise pollution cells in some cities are the operational entry points.

The National Green Tribunal, set up under the NGT Act, 2010, is a specialised environmental court with a Principal Bench in New Delhi and zonal benches in Bhopal, Pune, Kolkata and Chennai. Judicial and expert members sit together, which is what makes the tribunal effective — a judge alone rarely has the technical background to evaluate emissions data or hydrological reports.

NGT's original jurisdiction covers civil cases involving a substantial question relating to environment, and its appellate jurisdiction extends to orders of MoEFCC, SPCB, CPCB and the National Biodiversity Authority. The listed statutes are the Water Act, Air Act, Environment Protection Act, Forest Conservation Act, Biodiversity Act and Public Liability Insurance Act. Affected persons, environmental NGOs, and the tribunal acting suo motu can all initiate proceedings. Applications must be filed within six months of the cause of action (extendable by 60 days) using the prescribed form and a ₹1,000 court fee, backed by pollution evidence, records of regulatory action or inaction, and expert reports.

Once filed, the tribunal issues notice, frequently orders site inspections and expert committee reports, and can grant interim relief. Remedies are broad — restitution of the damaged environment, compensation to victims, restoration costs, closure of the polluting unit, and punitive damages under the polluter-pays principle. Landmark orders include the Sterlite Copper closure in Tamil Nadu, vehicular pollution controls in NCR, Diwali crackers restrictions, Ganga rejuvenation directions, and solid waste management enforcement. Appeals lie to the Supreme Court by SLP.

Compared with civil courts, NGT is faster (typical timeline 6 months to 2 years), better resourced technically, and has stronger enforcement teeth. Lawyer fees run from around ₹25,000 to ₹5,00,000 depending on complexity. Practical advice: document the pollution comprehensively, engage an environmental lawyer with NGT experience, coordinate with an established NGO, and build a solid expert evidence base before filing.

Your foundational protection is Article 21 of the Constitution — the Supreme Court has repeatedly held that the right to life includes the right to a clean environment. On top of that sit statutory rights to clean air and water under the various pollution Acts, a right to know through the Environmental Impact Assessment process, a right to public consultation before major projects clear EIA, and an RTI right to compliance information.

The civil route offers damages, injunctions, tort claims, and representative suits under Section 91 CPC for public nuisance. The criminal route runs through Section 270 BNS (public nuisance — 6 months or fine), Section 271 BNS (nuisance after notice), Section 296 BNS (annoyance in public way), Section 290 BNS (adulteration), and penal provisions embedded in each pollution Act. Administrative remedies — complaints to SPCB, CPCB, municipal authorities, or police, plus RTI for compliance status — usually produce fastest results if the violation is documented cleanly.

For systemic or large-scale violations, the NGT is the specialised forum, and a PIL in the High Court or Supreme Court is appropriate when multiple residents are affected. Health damage claims require medical evidence, and causation is the hardest link to prove; NGT has awarded compensation, and class actions are possible. Devaluation of property from pollution can support a civil suit.

Common nuisances have well-worn playbooks: construction dust — municipal stop-work under CAQM guidelines and CPCB norms; restaurant smoke — industrial-grade chimney and SPCB consent; diesel generators — CPCB-approved models with correct stack height; factory emissions — SPCB consent to operate with periodic monitoring; vehicle emissions — PUC enforcement and phase-out of ageing vehicles in NCR; garbage burning — ₹5,000 fine under Solid Waste Management Rules; stubble burning — ₹15,000-₹15 lakh under NCR-specific bans; crackers — time-bound, green-only in NCR. Local RWA organising, municipal petitions, awareness campaigns and media pressure often move the needle faster than filing alone. NGOs like Centre for Science and Environment (CSE), Greenpeace India, Care for Environment Trust and Climate Action Network South Asia can amplify your case.

Construction pollution is governed by the CPCB Construction & Demolition (C&D) Waste Management Rules, 2016. On any active site the operator must suppress dust with regular water sprinkling, store material under cover, barricade the plot, wash truck wheels before exit, and cover material in transit. NCR sites additionally fall under the Commission for Air Quality Management (CAQM), which enforces stricter norms and the Graded Response Action Plan (GRAP) — construction is halted during severe pollution episodes. To complain, go to the Municipal Corporation, SPCB or CPCB (and CAQM in NCR), and quote the project's SPCB consent number so inspection is easier to route.

Factories run on the SPCB consent to establish and operate regime. Units are colour-categorised — Red (highest pollution, strictest monitoring), Orange, Green and White (non-polluting). Red-category industries must run an Online Continuous Emission Monitoring System (OCEMS) feeding data to the regulator in real time, alongside stack monitoring and effluent treatment obligations. SPCB and CPCB have inspection powers under the Air Act and Water Act, and NGT / SPCB closure orders have become common enforcement tools.

Vehicles run on Bharat Stage VI emission norms since April 2020; older vehicles face phase-outs, particularly in NCR under the Voluntary Vehicle Modernisation Programme (2021), which mandates scrapping of 15+ year commercial vehicles and 20+ year private vehicles against a scrap certificate.

Sector-specific concerns include sponge iron clusters in Chhattisgarh and Jharkhand, tanneries in Vellore and Kanpur, NCR brick kilns and stone crushers, illegal mining (regulated by the EIA Notification 2006), and thermal power plants now required to install Flue Gas Desulphurization units under revised CPCB norms. E-waste is covered by the E-Waste (Management) Rules 2016 with Extended Producer Responsibility, biomedical waste by the Bio-Medical Waste Management Rules 2016, and plastic by the Plastic Waste Management Rules 2016, with single-use plastic banned from 1 July 2022.

For citizen action, check air quality on SAMEER or IQAir, report violations promptly, join community groups, and engage civil society organisations. Where residents suffer measurable harm, the polluter-pays principle supports NGT-ordered compensation and class actions for medical and property damage.
