As Diwali approaches, the annual debate over firecrackers returns. Beyond individual celebrations, how do evolving rules on timings, noise, and pollution impact public events? Here’s a breakdown of the regulations shaping community festivities.
The National View: A Push for Balance
For several
years, the Supreme Court of India has aimed to strike a balance between festive traditions and public health. Instead of a complete nationwide ban, the court has consistently championed a regulated approach. The framework, established in a landmark 2018 order and reiterated since, generally permits bursting firecrackers for a two-hour window on Diwali night, typically from 8 pm to 10 pm. The emphasis is on the use of 'green crackers', which are scientifically designed to be less polluting. The court has also rejected unrestricted, 24-hour use of fireworks, citing the severe impact on children, the elderly, and those with respiratory illnesses. In late 2026, the court even relaxed rules to conditionally allow certain types of joined green crackers, or 'laris', which were previously banned, provided they meet strict safety and emission norms.
What Are 'Green Crackers'?
The term 'green crackers' refers to fireworks developed by the Council of Scientific and Industrial Research-National Environmental Engineering Research Institute (CSIR-NEERI). They are not pollution-free but are designed to have a smaller environmental footprint. Compared to traditional fireworks, they reduce particulate matter emissions by at least 30% and produce less noise, staying within a 125-decibel limit. These crackers do not contain highly toxic chemicals like barium nitrate, arsenic, lithium, and mercury. To help the public identify them, genuine green crackers feature a CSIR-NEERI logo and a scannable QR code on the box, which verifies their authenticity and manufacturing details. Always buy from licensed sellers, as roadside stalls might sell illegal and unsafe products.
Rules in Major Cities Get Specific
While national guidelines exist, local authorities often issue their own, stricter rules based on regional air quality. Delhi, known for its severe winter pollution, has historically enforced stringent measures. As of mid-October 2026, a ban on most firecrackers remains the default position, pending final orders from the Supreme Court and the Commission for Air Quality Management (CAQM). In Mumbai, the Bombay High Court has issued a complete ban on bursting firecrackers on public roads and streets, a rule that now applies year-round for all festivals. However, this order does not cover private housing society compounds, where society rules and the 8 pm to 10 pm time limit still apply. In Kolkata, previous orders have allowed green crackers only between 8 pm and 10 pm. Meanwhile, Tamil Nadu, including Chennai, has a unique schedule due to local traditions. The state government typically allows two one-hour slots: 6 am to 7 am and 7 pm to 8 pm on Diwali day.
Guidelines for Public Events and Gatherings
Organising a public Diwali event with firecrackers requires navigating an extra layer of rules. The emphasis is on community safety and accountability. Many municipal bodies and police departments encourage community displays in designated open spaces rather than individual bursting in crowded lanes. For instance, recent orders in Mumbai require event organisers to install visible decibel meters to monitor noise levels and submit affidavits confirming compliance. In Kolkata, guidelines for Kali Puja pandals, which coincide with Diwali, mandate that no firecrackers be burst near the pandal or electrical connections. Organisers of large gatherings are often required to obtain specific permissions from local authorities, who may stipulate designated bursting zones, timings, and safety measures like keeping buckets of sand and water ready. In some areas like Pune, rules explicitly prohibit bursting crackers within 50 metres of any temporary firecracker stall. The goal is to ensure that large_scale celebrations do not endanger public safety or violate noise and pollution norms.
