Gen-2 joined green crackers | Explained

The Indian Supreme Court has permitted the use of 'Gen-2' green crackers, which are designed to reduce particulate matter emissions by 45-60%. While these fireworks are less polluting than conventional ones, experts note that the term 'green' is misleading as they still contribute to environmental pollution.
Why it matters
This decision balances traditional cultural practices with public health concerns regarding air quality during festive seasons.
Story so far: On September 30, the Supreme Court ruled out a nationwide firecracker ban and accepted CSIR-NEERI’s recommendation for a “limited and conditional relaxation”. This allows the manufacture of next-generation joined green crackers that meet noise, emission and safety norms ahead of Diwali. The Bench said it would not permit 24-hour bursting and would consider fixed time windows.
They are crackers whose chemistry has been reworked to release less particulate matter than conventional ones, without losing brightness, sound or shelf life. NEERI’s (CSIR-National Environmental Engineering Research Institute) changes include additives such as zeolite, water-releasing compounds that act as dust suppressants, and metallic composites that improve combustion. Conventional crackers rely on barium nitrate, antimony and other metals linked to respiratory disease.
