Green crackers will go on sale from Saturday, two days before Diwali, as the Supreme Court has allowed only eco-friendly fireworks in Delhi-NCR. These can be sold and used between Dhanteras and Diwali (October 20–21).
The court has restricted bursting to specific hours, between 6 am and 7 am, and again between 8 pm and 10 pm on Chhoti Diwali and Diwali. Police and Delhi Pollution Control Committee (DPCC) teams will monitor markets to ensure only certified green crackers are sold.
Conventional firecrackers are banned due to their high emissions. Authorities warn that only lower-emission green versions like anaars (flower pots), phuljhadis (sparklers), bombs, and chakkars are permitted this festive season.
What Are Green Crackers?
Green crackers are fireworks designed to reduce air pollution. They are made by lowering the size of shells, using fewer raw materials, and adding dust-suppressing chemicals. These changes help cut down harmful emissions.
Developed by the Council of Scientific and Industrial Research–National Environmental Engineering Research Institute (CSIR–NEERI), green crackers emit 30% less particulate matter and up to 20% fewer gases than traditional ones.
They are also free from barium salts and have lower levels of aluminium and sulphur. CSIR–NEERI has developed three main types, SWAS, STAR, and SAFAL, all aimed at reducing air and noise pollution.
How to Identify Green Crackers
You can identify a genuine green cracker by checking two key features on the packaging. First, look for the official Green Fireworks logo issued by CSIR–NEERI. Second, make sure there is a unique QR code printed on the box.
Scanning the QR code will show details about the manufacturer, the chemical formulation, and the CSIR–NEERI certification status. This helps confirm the authenticity of the product.
The “CSIR NEERI Green QR Code” app is available on the Google Play Store. It can scan and verify crackers instantly, helping buyers avoid counterfeit or banned products.
Difference Between Conventional and Green Crackers
| Feature | Green Crackers | Conventional Firecrackers |
|---|---|---|
| Definition | Eco-friendly fireworks that reduce harmful emissions | Fireworks with gunpowder and chemicals that cause high pollution |
| Composition | Use fewer raw materials, no barium, less aluminium and sulphur | Contain nitrates, chlorates, perchlorates, and heavy metals |
| Emission Reduction | 30% less particulate matter, 20% fewer gases | High emissions of PM, SO₂, and NO₂ |
| Oxidising Agents | Potassium nitrate and clean oxidisers | Barium, strontium, copper, and other toxic compounds |
| Examples | SWAS, STAR, SAFAL; anaars, phuljhadis, chakkars | All types of high-emission fireworks |
| Environmental Impact | Lower air and noise pollution | Severe air and noise pollution |
Who Certifies Green Crackers?
All green crackers are certified by CSIR–National Environmental Engineering Research Institute (CSIR–NEERI). The institute tests and approves formulations to ensure they meet emission and safety standards.
The certification also helps authorities track genuine manufacturers and keep illegal or counterfeit products out of the market. Only NEERI-approved products with valid QR codes can be sold or used.
Is There Any Logo or QR Code to Identify Green Crackers?
Yes. Every authorised green cracker must have the Green Fireworks logo and a unique QR code on its packaging. Only crackers with both features are certified for sale. Buyers are advised to scan the QR code before purchase to confirm authenticity.
If you plan to celebrate Diwali with fireworks, make sure they are certified green crackers. Check for the Green Fireworks logo and QR code before buying. Conventional firecrackers are illegal, and only verified green ones are allowed during limited hours. Choosing the right cracker means protecting your health, your city’s air, and the spirit of the festival.
