What Are Green Crackers? How to Identify Them and Safer Alternatives
Quick answer: Green crackers are firecrackers made with formulations developed by CSIR-NEERI, designed to cut particulate emissions by at least 30 percent compared with conventional crackers. Genuine packs carry the NEERI green logo and a QR code you can scan. They are cleaner, not clean.

Key takeaways
“Green” is a specific, tested formulation, not a sticker anyone can add.
Check three things: the logo, a QR code that opens real details, and a licensed seller.
Fake “green” boxes have turned up in markets, so a logo alone proves nothing.
Whether you can burst them depends on your city and the year. Delhi-NCR’s rules have changed again and again.
Green still means smoke. Cracker-free celebrations are the lowest-impact choice.
Introduction
You’re at a fireworks stall a few days before Diwali. One box has a green leaf on it and the word “eco-friendly”. The seller says it’s green, so it’s fine. Is it?
Honestly, you can’t tell from the label alone. “Green” has a specific meaning in India, but it has also become a sticker that gets slapped on all kinds of boxes. And the rules on what you can burst, and when, keep changing from year to year and city to city.
So let’s sort it out together. We’ll look at what green crackers really are, how to check whether a box is the real thing, where Delhi’s rules stand ahead of Diwali on 8 November, what green crackers still can’t do, and a few ways to keep the festival bright without the smoke.
What are green crackers?
Green crackers are firecrackers made with formulations developed by CSIR-NEERI, the Nagpur-based environmental research lab under the Council of Scientific and Industrial Research. The idea is simple: keep the sparkle and the bang, but cut the pollution that comes with them.
The story starts in court. In 2015, three children asked the Supreme Court to restrict firecrackers because of what they do to our air. That case became Arjun Gopal vs Union of India. In October 2018, the court prohibited conventional crackers in Delhi-NCR and allowed only reduced-emission alternatives. CSIR-NEERI was then brought in to define and develop them.
So green crackers aren’t a new kind of firework. They’re the familiar sparklers, flowerpots and maroons, reworked with smaller shells, different ingredients and additives that help keep dust down. The target is to cut particulate emissions by at least 30 percent, though the real reduction varies from product to product. CSIR-NEERI is also the agency that certifies them.
The three types: SWAS, STAR and SAFAL
If you went looking for a “green crackers name list”, these three names are the official categories:
SWAS (Safe Water Releaser): designed to release water vapour that helps keep dust from rising.
STAR (Safe Thermite Cracker): aims to cut dust and sound.
SAFAL (Safe Minimal Aluminium): uses minimal aluminium, as the name says.
There’s no brand list you can trust by name alone. What counts is whether the maker is on NEERI’s list of registered manufacturers.
A quick word on barium. Barium nitrate has long been used to give crackers their green colour, and NEERI’s formulations aim to cut or replace it. But the Supreme Court has been asking for open-ground testing of green crackers that still contain barium, so don’t assume “green” means barium-free.
How to identify green crackers: 4 quick checks
Look for the logo. Genuine packs carry the green CSIR-NEERI logo, along with PESO (Petroleum and Explosives Safety Organisation) details.
Scan the QR code. Use the CSIR-NEERI Green QR Code app. A real code opens details about the manufacturer, the formulation and the NEERI certification status.
Check the maker. The company name on the box should be on NEERI’s registered list. When reporters checked Nagpur markets in 2021, they found boxes with a NEERI logo but no PESO certification, no registration number, no QR code, and makers who weren’t on the list.
Buy from a licensed seller. Not a roadside stall. In Delhi-NCR in 2025, the court allowed sales only from designated points.
Red flags: a barcode where a QR code should be, a code that opens nothing, or missing PESO details. Testing by an NGO in Mumbai in 2021 found “green” boxes with barcodes instead of QR codes, and QR codes that weren’t registered with NEERI.
A logo can be printed on any box. The scan and the maker check are what actually tell you something.
Are green crackers allowed in India?
The answer depends on where you live and the restrictions in force. Green crackers are not automatically permitted across India. Their use depends on Supreme Court directions, state government rules and local restrictions, particularly during Diwali.
December 2024 to April 2025: the Supreme Court ordered a complete ban on firecrackers in Delhi-NCR, and a year-long blanket ban followed that covered green crackers too.
October 2025: for Diwali, the court relaxed the ban with conditions. Only NEERI-approved green crackers from registered, PESO-licensed makers, sold at designated points. No online sales, no crackers brought in from outside the NCR, and no joined crackers (laris). Bursting only between 6 and 7 am and between 8 and 10 pm, on the day before Diwali and on Diwali itself. Sellers dealing in fakes were to lose their licences.
30 September 2026: the court said it would not impose a total ban, but would not allow bursting all day either. In Arjun Gopal, it also accepted a proposal to permit specified next-generation joined green crackers under strict technical conditions. That order doesn’t by itself settle every Delhi-NCR restriction.
12 October 2026: the court passed no directions and asked the Commission for Air Quality Management (CAQM) for its view. The existing ban stayed in place for the time being, with the next hearing set for 15 October.
So what should you do? Check the order for your city a day or two before you shop, not on the day. Other states have their own rules. Karnataka, for instance, has told people to spot green crackers by the NEERI and PESO logo and QR code.
Are green crackers really safe?
Safer, yes. Safe, not quite. A lower-emission cracker is still a cracker, and the smoke is still fine particles (PM2.5 and PM10) along with gases like sulphur dioxide and nitrogen oxides. Those particles can travel deep into the lungs, which matters most for children, older people and anyone with breathing problems.
A cleaner cracker also isn’t a clean night. What ends up in your air depends on how many are burst, the weather, and how polluted the air already was. The Supreme Court itself has said that awareness and voluntary choices can work better than orders that are hard to enforce, and it has encouraged celebrations built around diyas.
Safer ways to celebrate that still feel like Diwali
You don’t have to give up the joy. A few swaps that families, societies and workplaces can try:
Let the lights do the talking. Diyas, string lights and rangoli fill a home with the glow people remember.
Keep one big moment, minus the smoke. A shared countdown, music or dhol on the lawn can stand in for the loudest few minutes of the night.
Celebrate together. One society get-together at an agreed time is easier on everyone’s lungs and ears than every building bursting its own.
Plan for the day after. Flowers and decorations have to go somewhere. Where temple flower waste goes shows what happens when it reaches a river, and how some cities now turn it into incense and compost instead. The same question comes up after Ganpati visarjan, and a small swap like shadu mati clay over Plaster of Paris is the same kind of choice.
Will it feel different? A little, honestly. Children may ask about crackers. Letting them pick the diyas, make the rangoli or choose the music helps.
Conventional, green or cracker-free: a quick comparison
Conventional | Certified green | Cracker-free | |
What it is | Standard formulations | CSIR-NEERI formulations, certified | Lights, music, shared activities |
Particulate matter | Baseline | Designed to cut by at least 30%, varies by product | None from bursting |
Barium | Barium nitrate has long been used | NEERI aims to cut or replace it, some products still under testing | None |
How to check | Not applicable | Logo, QR scan, registered maker, licensed seller | Not applicable |
Rules in Delhi-NCR | Prohibited since the 2018 order | Depends on the year’s order | No restrictions |
Left behind | Debris and packaging | Debris and packaging | Little |
A simple way to decide
Check your city’s current order first. If bursting isn’t allowed, or you’re unsure, go cracker-free.
If it is allowed and you want green crackers, scan every pack, buy only from licensed sellers, and burst only in the permitted hours, in open space.
If you’re organising for a society or an event, agree the plan in writing before the day, including the cracker-free moment and who clears up afterwards.
The bottom line
Green crackers are a real step up from conventional ones, and knowing how to check a box can save you from paying for a label. But green isn’t harmless, and the same smoke that fills the street fills our lungs. So check the logo, scan the code, and confirm the rule where you live. And if you’d like a Diwali with much less smoke, the loud part is the easiest bit to swap. Keep the diyas, the sweets and the people.

FAQs
1. Can I buy green crackers online?
Not in Delhi-NCR under the October 2025 order, which barred sales through e-commerce sites. Other states have their own rules, so check your local order first.
2. Are joined crackers (laris) allowed?
The 2025 Delhi-NCR order barred them. On 30 September 2026 the Supreme Court permitted specified next-generation joined green crackers under strict conditions, but that doesn’t by itself settle every Delhi-NCR restriction.
3. Are green crackers safe for children, older people or people with asthma?
Cleaner isn’t the same as safe. The smoke still contains fine particles that reach deep into the lungs. If anyone at home has breathing trouble, keep them away from the smoke.
4. Do green crackers make less noise?
They’re designed to be quieter, and approved products must meet the applicable noise and emission standards. Figures online vary, so rely on the details on the pack and the QR scan rather than a number you read somewhere.
5. What should UPSC aspirants remember about green crackers?
They were developed by CSIR-NEERI after the Supreme Court’s 2018 order in Arjun Gopal, come in three types (SWAS, STAR and SAFAL), are designed to cut particulate matter by at least 30 percent, and are identified by the green logo and a QR code. CSIR-NEERI certifies them, and PESO approves them.
