An environment law firm deals with one basic conflict. Someone wants to build, make or dispose of something, and someone else, or the land, water and air around it, pays the price. In India that conflict is decided under a handful of central Acts, a long list of rules, and three main forums, namely the pollution control boards, the National Green Tribunal and the constitutional courts. We're a Delhi NCR practice that handles both sides of it. Factory owners come to us with closure notices. Residents come to us with a stone crusher next door.
This guide explains what environmental lawyers in India actually do, which laws matter, where the cases go and how long you've got. It also covers what changed between 2023 and 2026, because a lot did. If you already know your problem, our page on environmental law services lists the work area by area, and NGT case filing covers the tribunal itself.
The essentials
Two sides, same law
Industries, builders, residents and villages all argue under the same Acts and before the same tribunal.
Deadlines are short
An appeal to the NGT is due within 30 days of the order, with at most 60 more days for good reason.
Five NGT benches
New Delhi, Bhopal, Pune, Kolkata and Chennai, each covering set states.
Penalties, not jail, for many breaches
Since 2023 to 2024, many offences under the green laws carry money penalties set by an adjudicating officer.
Paper wins cases
Consent orders, inspection reports, sample results and RTI replies decide more matters than speeches do.
No promised results
Any lawyer who guarantees an outcome in an environmental case is guessing. We tell you the risks plainly.
What does an environment law firm in India actually do?
Most of our work falls into four buckets. Getting permissions right before a project starts. Defending a unit when a pollution board or the NGT comes after it. Bringing a case for people who are suffering from pollution. And advising companies, buyers and lenders on environmental risk before money changes hands.
The day-to-day reality is less dramatic than the headlines. It's replying to a show-cause notice from the UPPCB in time. It's filing an appeal against a closure direction before the 30 days run out. It's sitting with a housing society's committee and working out whether their builder ever had the environmental clearance the brochure promised. Sometimes it's telling a client not to file at all, because the facts won't carry the case.
And it isn't only a Delhi thing. The law is central, the NGT sits in five cities, and hearings run on video. We take matters from across India, though a fair share of our files come from Delhi, Noida, Ghaziabad, Gurugram and Faridabad.
Where environmental law in India comes from
It starts with the Constitution. The Supreme Court has read the right to a clean and healthy environment into Article 21, the right to life. Article 48A asks the State to protect and improve the environment, and Article 51A(g) puts a duty on every citizen to protect forests, lakes, rivers and wildlife. In 2024, in M.K. Ranjitsinh v Union of India, the Court went a step further and recognised a right against the adverse effects of climate change.
On top of that sit the statutes. The Water Act of 1974 and the Air Act of 1981 created the pollution control boards and the consent system. The Environment (Protection) Act, 1986 is the umbrella law, and most of the detailed rules (waste, noise, plastic, e-waste, batteries, the EIA Notification) are made under it. Forests, wildlife and biodiversity each have their own Act.
Then there are the principles the courts built over forty years. Absolute liability for hazardous industries came out of M.C. Mehta v Union of India, the Oleum gas case, in 1987. The polluter pays principle and the precautionary principle were set down in Vellore Citizens' Welfare Forum v Union of India in 1996. These aren't just textbook ideas. Section 20 of the National Green Tribunal Act tells the tribunal to apply them, and it does, often.
The laws you'll hear about, and who enforces them
You don't need to memorise these. But it helps to know which law your problem sits under, because that decides the forum and the time limit.
| Law | What it controls | Who enforces it |
|---|---|---|
| Water (Prevention and Control of Pollution) Act, 1974 | Discharge of effluent and sewage, plus consent to establish and operate | State Pollution Control Board, or the Pollution Control Committee in a UT (DPCC in Delhi) |
| Air (Prevention and Control of Pollution) Act, 1981 | Emissions from chimneys, DG sets, boilers and crushers, plus consents | Same boards, and CAQM in Delhi NCR |
| Environment (Protection) Act, 1986 | Umbrella law covering standards, the EIA Notification 2006, and waste and noise rules | MoEFCC, CPCB, state boards, adjudicating officers |
| Van (Sanrakshan Evam Samvardhan) Adhiniyam, 1980 | Use of forest land for non-forest purposes | MoEFCC and state forest departments |
| Wild Life (Protection) Act, 1972 | Protected species, sanctuaries, national parks | Forest and wildlife officers, then the criminal courts |
| Biological Diversity Act, 2002 | Access to biological resources and benefit sharing | National and state biodiversity boards |
| Public Liability Insurance Act, 1991 | Insurance and relief for accidents with hazardous substances | Collector and the central government |
The waste rules deserve a mention of their own. Plastic, e-waste, battery, hazardous, bio-medical and construction waste each have separate rules under the EP Act. Many producers and importers now have Extended Producer Responsibility targets on a CPCB portal, which is a compliance headache we see a lot of. Our page on plastic EPR registration goes into that.
Where environmental cases are actually fought
The National Green Tribunal is the centre of gravity. It was set up under the NGT Act, 2010, and it has a Principal Bench in New Delhi and zonal benches in Bhopal, Pune, Kolkata and Chennai. Each bench covers a group of states, which our page on NGT zonal benches lays out. Under Section 14 it hears cases raising a substantial question about the environment under the seven Acts in its first schedule. Section 15 lets it award compensation and order the environment restored. Section 16 makes it the appeal forum against closure directions, environmental clearances and forest approvals.
Before most disputes reach the NGT, they go through a pollution board. A refusal of consent, for instance, first goes in appeal to the state appellate authority under Section 28 of the Water Act or Section 31 of the Air Act, and only then to the tribunal. Since the 2023 and 2024 amendments, many contraventions are now dealt with by an adjudicating officer who imposes a money penalty, and that order can also be taken to the NGT.
The High Courts haven't gone anywhere. Their writ powers under Article 226 still apply, especially where the problem is a government body simply not doing its job, or where the dispute falls outside the NGT's Acts (a pure wildlife or Indian Forest Act matter, for example). In practice, though, High Courts often send cases that fit the NGT Act to the NGT. The Supreme Court hears appeals from the NGT under Section 22, on questions of law, within 90 days.
One more Delhi NCR quirk. The Commission for Air Quality Management (CAQM) sets the rules for the region's air, including the GRAP stages that shut construction sites and DG sets in winter. A lot of our November and December calls are about CAQM directions.
The time limits that catch people out
This is where cases are lost before they start. Count from the date the order was communicated to you, not the date printed on it, and keep proof of that date.
| What you want to do | Where | Time limit |
|---|---|---|
| Raise a fresh environmental dispute (Section 14) | NGT | 6 months from when the cause of action first arose, plus up to 60 days for sufficient cause |
| Claim compensation or restoration (Section 15) | NGT | 5 years, plus up to 60 days |
| Appeal a closure direction, an EC, or a forest approval (Section 16) | NGT | 30 days from communication, plus up to 60 days |
| Appeal refusal or conditions of consent | State appellate authority | 30 days |
| Appeal an NGT order on a question of law (Section 22) | Supreme Court | 90 days, plus up to 90 more for sufficient cause |
| File a citizen complaint in a criminal court | Magistrate | Only after 60 days' notice to the board or government |
The extra 60 days is a discretion, not a right. The tribunal can't stretch it further, however good the reason. If you're near the edge, read our guide on whether it's too late to go to the NGT and talk to a lawyer the same week.
What's changed in environmental law since 2023
If your understanding of green law is a few years old, some of it's out of date. The biggest shift is decriminalisation. The Jan Vishwas (Amendment of Provisions) Act, 2023 replaced jail terms under the EP Act and the Air Act with money penalties for many contraventions. Under the EP Act, the penalty is now at least ₹10,000 and can go up to ₹15 lakh, with more for continuing breaches. The rules for how an adjudicating officer holds the inquiry and sets the penalty were notified in late 2024.
The Water (Prevention and Control of Pollution) Amendment Act, 2024 did much the same for the Water Act. It brought in penalties of ₹10,000 to ₹15 lakh instead of prison for most violations, with imprisonment kept for running a unit without consent. It applied at first to Himachal Pradesh, Rajasthan and the Union Territories, and other states adopt it by resolution. So whether it applies to your unit depends on your state. Check before you assume.
Forest law changed its name and its scope. The Forest (Conservation) Amendment Act, 2023 renamed the 1980 law the Van (Sanrakshan Evam Samvardhan) Adhiniyam and narrowed which land it covers. Challenges reached the Supreme Court, and in 2024 the Court directed, as an interim measure, that the wide dictionary meaning of 'forest' from the T.N. Godavarman case should still be followed. That challenge is still the thing to watch before any project on wooded land.
Then there's the back-and-forth on after-the-event clearances. In May 2025, in Vanashakti v Union of India, a two-judge bench struck down the 2017 notification and the 2021 office memorandum that allowed ex post facto environmental clearance. In November 2025, a three-judge bench recalled that judgment by a 2:1 majority on a review petition, and the matter went back for fresh consideration. If your project started without EC, the law here is genuinely unsettled. Don't let anyone tell you otherwise.
A smaller change, but a practical one. The Solid Waste Management Rules, 2026 replaced the 2016 rules from 1 April 2026, with four-way segregation at source and heavier duties on bulk waste generators like large societies, malls and institutions. RWAs that ignored the old rules are now getting notices under the new ones.
Who needs an environmental lawyer?
Pretty much anyone whose work or home touches land, water or air in a way the law cares about. These are the people who actually call us.
- Factory and unit owners. A show-cause notice has arrived, the CTO renewal is stuck, or the board has already ordered closure and cut the power. See pollution control board notices.
- Builders and developers. They need prior environmental clearance for projects of 20,000 sq m built-up area and above, or they've been taken to the NGT by buyers or neighbours.
- Housing societies and RWAs. The STP never worked, sewage goes into the storm drain, and the builder says it's the society's problem now.
- Villagers and farmers. A crusher, brick kiln or dyeing unit has come up next to fields, the borewell water has turned, and the local office isn't answering.
- NGOs and concerned citizens. They want a lake, a ridge or a green belt protected and need the case built properly. Our community and NGO cases page covers this.
- Companies, buyers and lenders. They want to know, before signing, whether a plant has valid consents, an EC that matches what's actually built, and no pending compensation demand.
- Project proponents on forest or eco-sensitive land. Mines, roads, resorts and solar parks often need forest clearance or wildlife approvals, and a mistake here can stop a project for years.
What we do when a business is in trouble
Most business clients reach us after a notice, not before. That's normal, and it's usually still fixable. The first job is to read the notice for what it actually alleges. A board that writes 'operating without valid CTO' is making a different case from one that writes 'discharge exceeding standards', and the reply has to meet the allegation it's facing, with documents.
If closure has already been ordered under Section 33A of the Water Act, Section 31A of the Air Act or Section 5 of the EP Act, there are two tracks. One is compliance. Fix what's wrong, get it inspected, and apply for revocation, often with a bank guarantee. The other is an appeal to the NGT within 30 days, if the order is wrong in law or was passed without a fair hearing. Often we run both at once. Frankly, the compliance track reopens more units than litigation does. But a good appeal keeps the pressure on, and sometimes it gets an interim order that lets the unit run while the dispute is decided.
Then there's the steady work. Getting consent to operate renewed before it lapses. Fighting an environmental compensation demand that was worked out on the wrong number of days. Keeping EPR filings straight. None of it's glamorous. All of it matters when an inspection team turns up unannounced.
What we do for residents, villages and RWAs
People suffering from pollution usually try the local route first, and they should. A written complaint to the pollution board, a copy to the DM or SDM, an RTI asking for the unit's consent order and last inspection report. Those papers become the spine of any later case. Our guide on how to file a case in the NGT explains when to stop writing letters and go to the tribunal.
When we take a residents' matter to the NGT, the tribunal usually doesn't decide it on affidavits alone. It often forms a joint committee, typically the CPCB, the state board and the District Magistrate, to inspect the site and report back. That report is where most cases are won or lost. We help clients prepare for the inspection and file objections if the report glosses over what's really happening.
Compensation is possible too, under Section 15, for damage to health, property or crops. But be realistic. The NGT more often orders the polluter to stop, fix and pay environmental compensation to a fund than to pay large sums to individuals. Our page on compensation for pollution damage explains what's actually recoverable.
How an NGT case moves, start to finish
Every case is different, but most follow roughly this path. Knowing it helps you plan, and it stops the surprises.
Check the forum and the clock
We confirm the dispute falls under the NGT's Acts and work out the time limit from the date of the cause of action or the order. If it doesn't fit, we say so and suggest the right forum.
Collect the record
Consent orders, the EC, inspection reports, photos with dates, sample results, complaints already made and RTI replies. Gaps get filled by fresh RTIs where there's time.
Draft and file
The application or appeal sets out the facts, the law, the relief and the documents. Filing is done through the NGT's e-filing system with the court fee.
First hearing
The bench decides whether to issue notice. It may ask the board or the district administration for a factual report, or form a joint committee to inspect.
Reports and replies
The other side files its reply, the committee files its report, and we file objections and a rejoinder. This stage takes the longest.
Arguments and order
The tribunal hears both sides and passes an order. It may give directions, award compensation, order closure, impose conditions or dismiss the case. Section 18(3) aims for disposal within six months, though many cases take longer.
After the order
If the order is ignored, an execution application follows, and Section 26 makes non-compliance an offence. If the order is wrong in law, an appeal lies to the Supreme Court within 90 days.
Our page on environmental and NGT lawyers for cases across India covers how we handle matters outside Delhi, mostly by video hearing.
Papers to collect before the first meeting
If you run a unit or project
- The notice, order or direction, with the envelope or email showing the date you got it
- Current CTE, CTO and any earlier consent orders
- Environmental clearance, if any, and its conditions
- Recent sample and test reports, and the logbooks for ETP, STP or APCD
- Electricity and water bills, if supply has been cut
- Any earlier replies sent to the board
If you're affected by pollution
- Photos and videos, with dates, and a short diary of incidents
- Copies of every complaint you've sent and any reply
- RTI applications and replies
- Medical records, crop loss records or repair bills, if you're claiming damage
- Names of neighbours willing to sign or give statements
- Any newspaper report about the site
A made-up example of an RMC plant behind a society
This one is invented, but it's built from the kind of call we get every month. A ready-mix concrete plant sets up on agricultural land behind a 600-flat society in Greater Noida. Within weeks there's dust on every balcony, trucks run through the night, and children in the society start coughing more than usual.
The RWA writes to the UPPCB twice and gets no reply. It files an RTI and learns the plant has applied for consent but hasn't got it. That's the moment to stop writing letters. The society files an application before the NGT Principal Bench under Section 14, attaching the RTI reply, dated photos, the complaints and a list of residents' medical visits. It asks for a joint inspection, for the plant to be stopped until it holds valid consent, and for environmental compensation to be assessed.
What happens next isn't in the society's hands. The tribunal could call for a report, form a committee, or issue directions to the board. The point of the example is the order of steps. First the complaint, then the RTI, then a properly documented filing, all inside the time limit.
How much does it cost, and how long does it take?
Tribunal fees are modest. Under the NGT's procedure rules, an application or appeal that doesn't claim compensation carries a fee of ₹1,000. Where compensation is claimed, it's 1% of the amount claimed, with a ₹1,000 minimum. Printing and copying charges come on top. Fees can change, so check the current schedule when you file.
Our professional fees aren't published here, as Bar Council rules don't allow it. What we can tell you is how we work. We discuss the scope first, put the fee in writing, and break it into stages (drafting, filing, hearings, any appeal) so you know what each part costs before it starts.
Time is harder to predict. A reply to a show-cause notice takes days. A consent appeal before the state appellate authority may take a few months. An NGT matter with a joint committee inspection often runs well past the six-month target in Section 18(3), and a Supreme Court appeal adds more. We'll give you a realistic estimate for your matter, not a hopeful one.
Mistakes we see again and again
- Letting the 30 days slip. People wait for the board to reconsider, or for a meeting that never happens, and lose the appeal before they've started.
- Replying without documents. A two-line letter saying 'we're fully compliant' rarely persuades anyone. Attach the test reports and the consent.
- Going to the wrong forum. A pure Wild Life Act offence doesn't belong in the NGT, and a consent refusal usually has to go to the appellate authority first.
- Treating closure as the end. Many closed units reopen through compliance and a revocation order. Panic leads to bad decisions, like restarting in secret.
- Overclaiming. Residents sometimes plead every harm they can think of. A tighter case built on what you can prove usually lands better.
- Ignoring the inspection. When the joint committee visits, someone who knows the facts needs to be there, with papers ready. Absence gets read as having nothing to say.
- Assuming the law is the same as last year. Penalties, consent exemptions and clearance rules changed between 2023 and 2026. Old advice can now be wrong advice.
How to choose an environmental lawyer in India
You'll see plenty of firms calling themselves the best. Bar Council rules don't let lawyers say that, and it tells you nothing anyway. Ask practical questions instead.
- Do they appear regularly before the NGT and the pollution boards, or is environmental work occasional for them?
- Can they explain, in plain words, which law your problem sits under and what the time limit is?
- Will they tell you when not to file, or when compliance is a better route than a fight?
- Do they handle both sides (industry and affected parties), so they know how the other side will argue?
- Will the fee be agreed in writing, stage by stage, before work starts?
- Can they appear at the bench that covers your state, or by video if that bench is far away?
- Do they keep you updated after each hearing, with a copy of the order?
If the answers are vague, keep looking. A good environmental lawyer is usually happy to explain the risks before talking about the fee.

Frequently Asked Questions
What does an environment lawyer in India actually do?
Two kinds of work, mostly. The advisory side means getting consents, environmental clearance and EPR registrations right before anything goes wrong. The contentious side means replying to pollution board notices, fighting closure orders and running cases before the NGT, High Courts and Supreme Court, for businesses as well as for people hit by pollution.
When should a business bring in an environmental lawyer?
Ideally before you buy land or order machinery, because that's when a wrong consent category or a missing clearance is cheap to fix. The other moments are an expansion, a change of product, a renewal that's stuck, and the day a notice arrives. Waiting until power has been cut is the expensive route.
Which environmental laws apply to my business?
It depends on what you make, how big you're and where you sit. Almost every unit deals with the Water Act and the Air Act through its consents, and with the EP Act through waste, noise and emission rules. Projects on forest land, near a sanctuary or along the coast pick up extra laws on top.
What is environmental clearance, in plain words?
It's prior permission, under the EIA Notification 2006, to start certain projects that could seriously affect the environment. Without it, the project can't lawfully begin construction or expansion. It comes with conditions, and breaking those conditions is a violation in its own right.
Which projects need environmental clearance before work starts?
The schedule to the EIA Notification lists them by sector and size, covering mining, thermal power, cement, chemicals, large building projects and many more. For buildings, the line is 20,000 sq m of built-up area. Category A projects go to the central ministry, Category B to the state authority (SEIAA).
What is an EIA, and does every project hold a public hearing?
An Environmental Impact Assessment is the study of what a project will do to air, water, land and people, and how that harm will be reduced. Category A and B1 projects generally go through public consultation, which includes a public hearing near the site, though the notification exempts some categories. Smaller B2 projects skip the full study.
Does every factory need consent from the pollution board?
No. The CPCB sorts industries into red, orange, green and white categories by how much they pollute. White category units, the cleanest, don't need consent at all, and recent notifications have exempted some others. Everyone else needs it, so check your category before you assume you're out.
What's the difference between CTE and CTO?
Consent to Establish is the board's permission to set up the unit, and you need it before construction. Consent to Operate is permission to actually run it, granted after the board is satisfied the pollution controls are in place. A unit can hold a valid CTE and still be operating illegally if it never got its CTO.
What approvals does a new industrial project usually need?
Typically CTE and then CTO from the state board, environmental clearance if the project falls in the EIA schedule, a groundwater NOC if you'll draw water, and authorisations under the waste rules if you'll handle hazardous waste. Forest, wildlife or coastal approvals are added where the site calls for them.
What do I have to keep doing after the unit starts running?
Follow the consent conditions, monitor and record emissions and effluent, keep waste records and manifests, renew consents before they expire and file the annual environmental statement in Form V by 30 September. EC projects also file six-monthly compliance reports. Most trouble starts with records nobody kept.
We've received a notice from the pollution control board. What now?
Note the date you got it and the deadline to reply, then read exactly what it alleges. Collect the consent, test reports and logbooks that answer it, and fix anything genuinely wrong straight away. Reply in writing, on time, with documents. A vague or late reply is how closure orders happen.
What happens if a business breaks environmental law?
It can face directions to stop or correct, environmental compensation, money penalties (₹10,000 to ₹15 lakh under the amended EP Act and Water Act), and in some cases prosecution, mainly for running without consent. The board can also order closure and cut electricity and water. Lenders and buyers notice all of this.
Can the authorities shut a factory down?
Yes. Section 33A of the Water Act, Section 31A of the Air Act and Section 5 of the EP Act let the board or the government order closure and stop electricity, water or other services. A show-cause notice and a hearing usually come first. The direction can be appealed to the NGT within 30 days.
What goes wrong legally with careless waste disposal?
Hazardous waste must go only to authorised handlers, with a manifest tracking every load. Dumping it, mixing it with ordinary waste or handing it to an unauthorised transporter can bring closure, compensation for clean-up and penalties, plus civil claims from people whose land or water is damaged.
Do construction and infrastructure projects need environmental approvals?
Many do. Buildings of 20,000 sq m and above need prior EC, and most projects also need CTE and CTO, a groundwater NOC, construction and demolition waste arrangements and, in Delhi NCR, compliance with CAQM dust rules. Roads, ports and townships can pick up forest or coastal approvals too.
Can a lawyer run a compliance audit of our plant?
Yes, and it's often worth doing before a sale, a funding round or a board inspection. We check each consent and clearance against what's actually built and running, go through monitoring records and waste paperwork, and give you a list of gaps with a fix for each. It's cheaper than finding them during a raid.
Can we challenge an order from the pollution board?
Usually, yes. A refusal of consent or harsh conditions go first to the state appellate authority within 30 days. Closure directions, environmental clearances and forest approvals can be appealed straight to the NGT within 30 days. Penalty orders of an adjudicating officer can be taken to the NGT too, after depositing part of the penalty.
Can an environmental dispute go to the National Green Tribunal?
If it raises a substantial question about the environment under one of the seven Acts in the NGT Act's first schedule, yes. That covers most pollution, clearance and forest-diversion disputes. Pure Wild Life Act or Indian Forest Act offences don't fit, and go to the regular courts.
How can a company keep its environmental risk low?
Keep a calendar of every consent and renewal date, make one person responsible for compliance, keep monitoring records honest and complete, and fix small breaches before an inspector finds them. When you expand or change products, get fresh consent first. Most of our closure cases began with a missed renewal.
How much does an environmental lawyer cost in India?
It depends on the work. A notice reply costs far less than a contested NGT appeal with inspections. We don't publish fees because Bar Council rules don't allow it. We agree the fee in writing, stage by stage, before starting, so there are no surprises.
When should an existing project review its compliance?
Whenever something changes, such as more capacity, a new product, a new process, a change of ownership, a consent coming up for renewal, an accident or a new rule (like the Solid Waste Management Rules, 2026). Once a year is a sensible minimum even if nothing seems to have changed.
Can people living near a polluting unit take action themselves?
Yes. Complain in writing to the pollution board and the DM, file an RTI for the unit's consent and inspection reports, and if nothing happens, approach the NGT within the time limit. Compensation for damage can be claimed under Section 15 of the NGT Act within five years.
Got a notice, an order or a pollution problem?
Send us the notice, the order or a short description of what's happening on WhatsApp, or call. We'll tell you which forum it belongs in, how much time you've and what the realistic options are.
This page gives general information about environmental law as it stood when it was last reviewed. It is not legal advice on your case and does not promise any result. Laws, rules, fees and time limits change, so check the current position for your matter before acting.
