Green Crackers: A Cleaner Diwali Option?

Green crackers represent a significant advancement in reducing firework pollution, with a goal of at least a 30% reduction in particulate matter emissions. These eco-friendlier alternatives also aim for a 10% decrease in gaseous emissions and keep noise levels below 125 decibels at four meters. Their composition notably uses less aluminum, sulfur, and potassium nitrate than traditional fireworks. Crucially, green crackers are manufactured without hazardous chemicals such as barium nitrate, lithium, mercury, arsenic, and cadmium. Consumers can easily identify authentic green crackers by a distinct green logo from CSIR-NEERI and PESO, accompanied by encrypted QR codes. Despite these improvements, studies indicate that green crackers can still release dangerous ultrafine particles. The Supreme Court has permitted their use during specific hours, aiming to balance celebration with environmental concerns. Historically, Delhi has seen fluctuating pollution levels around Diwali, with various bans and regulations implemented over the years. In 2025, specific time slots were designated for green cracker usage, though adherence varied.
