Deepavali firecracker rules across India: Green crackers, pollution concerns and the enforcement gap

Several Indian states have restricted Diwali (Deepavali) fireworks through green-cracker rules, time limits and local bans. But do these measures reduce pollution, are they followed, and what happens when people violate them? A look at the rules, enforcement and penalties.

Firecracker restrictions during Diwali vary across India, with several states limiting their use to specific hours and allowing only certified green crackers. While some regions have introduced temporary relaxations, others have imposed complete bans in pollution-sensitive areas. These measures aim to reduce air and noise pollution, prevent accidents and protect public health. However, differences in state rules and challenges in enforcement raise an important question: are these restrictions actually making a difference?

Which states have similar Diwali firecracker restrictions?

Firecracker restrictions vary across India. While some states permit only certified green crackers during fixed hours, others have imposed complete bans in pollution-sensitive areas.

Karnataka: Only certified green crackers are allowed between 8 pm and 10 pm from November 8 to 10. District-level task forces have been directed to monitor compliance.

Delhi-NCR: The Supreme Court has permitted green crackers on November 7 and 8, between 6 am and 7 am and 8 pm and 10 pm. A complete ban returns on November 9. Fireworks are also prohibited within 300 metres of specified healthcare facilities, old-age homes and silence zones.

• Haryana: A complete ban on fireworks applies in its NCR districts, including Gurugram and Faridabad. Other districts allow green crackers between 8 pm and 10 pm.
• West Bengal: Only certified green crackers are permitted between 8 pm and 10 pm on Diwali.
• Tamil Nadu: In 2025, the permitted timings were 6 am to 7 am and 7 pm to 8 pm. A separate statewide timing notification for 2026 has not been verified.

Why are firecrackers restricted?

The main objective is to reduce air pollution, noise pollution, fire accidents and public-health risks.

Firecrackers release particulate matter such as PM2.5 and PM10, along with gases that can worsen air quality. The impact can be particularly serious in cities where winter weather conditions prevent pollutants from dispersing quickly.

Loud fireworks can disturb infants, senior citizens and patients. Improper handling can also cause burns, eye injuries and fires, particularly in crowded areas and near buildings or electrical installations.

Do green crackers actually reduce pollution?

Green crackers, developed through research involving CSIR-NEERI, are designed to produce fewer emissions than conventional fireworks. However, they are not pollution-free.

They can still release smoke, particulate matter and gases. Their actual environmental impact depends on their composition and manufacturing quality. Consumers should check whether products are certified rather than relying only on packaging claims.

Green crackers may reduce some emissions, but they cannot eliminate the environmental and health impact of fireworks.

Do two-hour restrictions actually work?

Fixed time windows can limit the period during which firecracker emissions are released. However, their effectiveness depends on whether people follow the rules and authorities prevent illegal sales.

The benefits are reduced when conventional crackers are sold illegally or fireworks are burst outside permitted hours. Emissions can also remain concentrated during the allowed period.

The Supreme Court has repeatedly raised concerns about the enforcement of firecracker restrictions in Delhi-NCR. Its latest order allows a limited two-day window for green crackers, followed by a complete ban from November 9.

It is also important to remember that firecrackers are only one contributor to India's air-pollution problem. Vehicle emissions, industrial activity, construction dust and agricultural burning also affect air quality.

Are the restrictions properly enforced?

Enforcement remains a major challenge. Announcing restrictions does not automatically ensure that they are followed.

Haryana authorities have been directed to monitor firecracker sales and use, while concerns have been raised about illegal fireworks and inconsistent enforcement.

West Bengal has announced inspections of markets, manufacturing units and storage facilities to prevent the sale of unauthorised products.

In Delhi-NCR, the Supreme Court has questioned the implementation of earlier restrictions and stressed the need to prevent illegal sales and the use of conventional crackers.

What penalties can violators face?

Depending on the applicable rules and the nature of the violation, authorities can seize prohibited fireworks, take action against illegal manufacturers and sellers, and prosecute offenders under relevant environmental and explosives laws.

In its May 2025 directions concerning Delhi-NCR, the Supreme Court said violations of directions issued under Section 5 of the Environment (Protection) Act should attract action under Section 15. Officials who fail to implement binding court directions may also face contempt proceedings.

What needs to improve?

For the restrictions to have a meaningful impact, authorities need to inspect markets and warehouses, verify green-cracker certification and prevent illegal manufacturing and sales.

Police and local enforcement teams must monitor compliance with permitted timings and take action against repeat offenders. Publishing details of seizures, prosecutions and air-quality readings would also help assess whether the restrictions are working.

India's firecracker policy faces an enforcement test

India has increasingly relied on restricted timings, certified green crackers and location-specific bans to regulate fireworks during Diwali. However, the rules differ across states and even between districts.

The effectiveness of these measures depends on consistent enforcement, public compliance and action against illegal products. Green crackers and shorter time windows may reduce some emissions, but they cannot solve India's wider air-pollution problem.

The key question is not simply how many restrictions governments announce, but whether those rules are followed and whether they lead to measurable improvements in air quality.
