Polluted Delhi Tries ‘Green’ Fireworks to Clear the Air at Diwali

India’s capital is expected to light up with a new generation of fireworks this Diwali, a move prompted by a fresh ruling from the Supreme Court that bans conventional pyrotechnic displays in the city for the festival period. The court, citing soaring levels of fine particulate matter and nitrogen oxides that routinely plunge Delhi’s air quality index into dangerous territory, has restricted the use of traditional crackers to those that emit less than 50 ppm of particulate matter. The decision follows months of public outcry over the severe smog that has repeatedly forced schools to close and hospitals to increase oxygen supply..

The new “green” fireworks, according to officials, are made with biodegradable casings and low‑smoke powders, promising to reduce the atmospheric burden by up to 70 percent.The announcement has been met with a mixture of relief and scepticism. While environmentalists welcome the move as a step toward sustainable celebration, many activists argue that the regulations are more symbolic than substantive, labeling the initiative a “green wash.” The term has been adopted by a coalition of NGOs that point out that even low‑smoke fireworks still release trace amounts of heavy metals such as lead and cadmium. They claim that the broader environmental impact—ranging from the sourcing of raw materials to the waste generated after the festival—remains largely unaddressed..

“If you are going to clean the air, you must also consider what is in the fireworks and where it ends up,” says Suman Reddy, a senior researcher at the Centre for Environmental Studies in New Delhi. “A small reduction in particulate matter is a drop in a very large problem.”The Supreme Court’s directive, issued in a 7‑to‑3 majority, was backed by data from the Indian Meteorological Department and the National Atmospheric Deposition Monitoring Programme. It stipulated that vendors must obtain certification from the Ministry of Environment, Forest and Climate Change to produce fireworks that meet the new standards..

The government has pledged to launch a nationwide training programme for artisans, who form the backbone of India’s fireworks industry, to ensure that the transition does not jeopardise livelihoods. The Ministry’s spokesperson said that the initiative is part of a larger plan to curb Delhi’s pollution levels by 30 percent over the next five years.Despite the court’s mandate, many residents remain doubtful about the practicality of the new fireworks. The market for traditional crackers has long been dominated by small‑scale manufacturers who rely on inexpensive, high‑impact products..

The shift to cleaner alternatives involves higher production costs, which could translate into higher retail prices. “We’re not just buying a product; we’re buying a feeling of celebration,” says Arjun Patel, a shopkeeper on the bustling lanes of Karol Bagh. “If the fireworks are too expensive or don’t produce the same visual spectacle, people will be hesitant to switch.” Patel’s shop, which sells over 20,000 packets of crackers annually, is reportedly preparing to stock a limited batch of the new eco‑friendly range, though he admits the demand is uncertain.The Indian government has attempted to smooth the transition by offering subsidies to manufacturers who meet the certification criteria..

The subsidies, amounting to up to 15 percent of the production cost, are intended to offset the initial investment in new machinery and raw materials. Industry bodies, however, have expressed concern that the subsidies may not be sufficient to cover the entire cost differential. “We have a complex supply chain,” explains Rajesh Kumar, president of the All India Pyrotechnics Manufacturers Association..

“From the sourcing of sulfur to the final packaging, every stage incurs an extra expense. The subsidy is a start, but we need a more comprehensive approach to make clean fireworks competitive.”Environmental NGOs have taken a different tack, focusing on the broader cultural context of fireworks in India. “Diwali is not just about the lights; it’s about community, family, and tradition,” says Aditi Sharma, director of the Green Delhi Initiative..

“If we are to preserve the festival’s essence, we must ensure that the celebration does not become a health hazard.” Sharma’s organisation has launched a public awareness campaign that encourages families to use alternative forms of celebration, such as sparklers made from natural materials and LED displays. The campaign, which has already garnered support from over 50,000 users on social media, argues that a gradual shift away from fireworks would be more sustainable in the long run.The new regulations also carry a significant enforcement challenge. Delhi’s enforcement agencies have traditionally struggled to monitor the vast number of vendors operating in informal settings across the city..

The Supreme Court has, however, mandated that the Delhi Police and the Fire and Emergency Services Department conduct random inspections on the eve of Diwali. The police have already deployed 1,500 officers to monitor major market hubs and have set up temporary checkpoints to check compliance. In addition, a digital registry system has been introduced to track the certification status of every fireworks vendor..

Vendors who fail to comply risk fines of up to ₹200,000 and the revocation of their operating licenses.The economic impact of the ban on conventional fireworks is still unfolding. Early estimates suggest that the fireworks sector could lose up to 15 percent of its revenue this year, according to a report by the National Council of Applied Economic Research. Yet the report also notes that the transition could create new jobs in the green technology sector, from manufacturing of biodegradable casings to the development of new low‑smoke powder formulations..

The Ministry of Commerce is reportedly working on a framework to facilitate foreign investment in this niche market, hoping to attract expertise from countries with a long history of green fireworks, such as Germany and the United Kingdom.Public opinion appears divided, as seen in a recent poll conducted by the Centre for Social Studies. The poll found that 58 percent of respondents support the use of cleaner fireworks, citing health concerns, while 35 percent expressed doubt about the effectiveness of the new products. The remaining 7 percent were either undecided or had no opinion..

The poll’s methodology, which surveyed over 2,000 Delhi residents across all age groups and socioeconomic strata, is praised for its robustness. However, critics argue that the sample may overrepresent urban middle classes, potentially skewing the results.The Supreme Court’s decision also raises legal questions about the balance between public health and cultural practice. The court acknowledged that fireworks are deeply embedded in Indian cultural celebrations, but it reiterated that the right to life and health supersedes the right to tradition when the latter poses an existential threat..

The ruling may serve as a precedent for future regulatory attempts to curb pollution in other urban centres, such as Mumbai and Kolkata, where air quality is similarly compromised during festival periods.As the city prepares for a quieter yet colourful Diwali, the real test will.
