Sound and fiery

1. At a Glance

• "Sound and fiery" is a The Hindu editorial (Chennai edition, page 12, 14 October 2026). It argues that green crackers do little to curb air and noise pollution in Delhi-NCR [1].
• The topic is the decade-long series of Supreme Court orders on firecrackers: a licence suspension in 2016, then the Arjun Gopal vs Union of India judgment in 2018, then permission for "next-generation" joined green crackers [1].
• The editorial calls green crackers "a pyrrhic green". They are a technology fix for a problem whose main causes lie elsewhere [1].
• UPSC relevance: environmental governance, judicial activism, the clash between Article 21 and religious/cultural sentiment and livelihoods, and the sources of urban air pollution.

2. Why in the News

• The latest Supreme Court order permits specified next-generation joined green crackers. It declines a total ban on fireworks, citing public sentiment [1].
• Delhi-NCR is heading into winter, its seasonal air-quality crisis, and Deepavali is near [1].
• Deepavali 2025 was the first after the Court allowed limited use of green crackers. Delhi's post-Deepavali PM2.5 average reached 488 µg/m³, the highest since 2021. Hourly peaks hit 675 µg/m³ [1].

3. Background & Evolution

• November 2016: The SC suspended licences for the sale of fireworks in NCR. Deepavali had pushed PM2.5 above 700 µg/m³ [1].
• September 2017: The SC relaxed the suspension, partly to protect existing licence holders and livelihoods [1].
• October 2017: The SC restored the suspension for Deepavali [1].
• 2018: In the Arjun Gopal & Ors vs Union of India & Ors judgment, the SC [1]:
• allowed only reduced-emission and "green" crackers
• banned joined firecrackers (laris)

• imposed a two-hour window for bursting.

• 2025: The SC permitted limited use of green crackers in Delhi-NCR [1].

• Latest order: Specified next-generation joined green crackers are allowed. This partly reverses the 2018 ban on laris. A total ban is declined [1].
• Who developed them: Green crackers were promoted by CSIR-NEERI (Council of Scientific and Industrial Research–National Environmental Engineering Research Institute) [1].

5. Multi-Dimensional Analysis

Environmental

• Crackers are not the main cause of Delhi's winter smog. They do cause an acute spike once other sources have already pushed air quality towards "severe" [1].
• Green crackers still emit. 2025 recorded the highest post-Deepavali PM2.5 since 2021 even with green crackers allowed [1].
• The editorial's title stresses noise pollution alongside air pollution [1].

Legal / Constitutional

• The SC has repeatedly loosened and tightened the regime: suspend, relax, restore, restrict, relax [1]. The editorial's image is a foe "kept on a leash".
• The latest order rests partly on public sentiment. This raises the question of how to weigh the right to a healthy environment (Art. 21) against cultural and religious practice.

Economic / Social

• The 2017 relaxation was meant partly to protect licence holders and livelihoods [1].
• Health costs fall hardest on children, the elderly and outdoor workers. (Analytical point, no source.)

Scientific / Technological

• CSIR-NEERI says each newer generation of green crackers performs better [1], but measured outcomes in 2025 do not show the gains [1].
• An independent check is needed on whether emission-reduction claims hold up in real use.

Governance / Administrative

• Without strong enforcement, a two-hour window and a green-only rule are hard to police. Telling green crackers apart from conventional ones in the market is especially hard.
• An airshed-wide problem calls for regional coordination across NCR states, not a festival-specific court order.

6. Recent Developments (last 12–18 months)

• Deepavali 2025: first festival with limited green-cracker use. PM2.5 averaged 488 µg/m³ with an hourly peak of 675 µg/m³ [1].
• 2026 SC order: next-generation joined green crackers permitted and a total ban declined [1].
• 14 Oct 2026: The Hindu editorial "Sound and fiery" criticises the green-cracker approach [1].

7. Prelims Hooks

• The SC suspended firecracker sale licences in NCR in November 2016 [1].
• That suspension followed PM2.5 levels above 700 µg/m³ after Deepavali [1].
• The SC relaxed the suspension in September 2017 and restored it for Deepavali in October 2017 [1].
• Arjun Gopal vs Union of India (2018) is the landmark firecracker judgment [1].
• The 2018 judgment banned laris (joined crackers) [1].
• The 2018 judgment imposed a two-hour window for bursting crackers [1].
• Green crackers were developed and promoted by CSIR-NEERI [1].
• The latest SC order permits next-generation joined green crackers [1].
• The SC declined a total ban, citing public sentiment [1].
• Delhi's post-Deepavali PM2.5 average in 2025 was 488 µg/m³, the highest since 2021 [1].
• PM2.5 means particulate matter ≤ 2.5 micrometres in diameter [unverified; standard definition].

8. Why Cleaner Crackers Do Not Mean Cleaner Air

• A smaller cut per cracker is lost when more crackers are burst
• Green crackers are said to give out about 30–40% less particulate matter (tiny dust particles) and sulphur dioxide than normal crackers [2].
• Experts warn that wide use can cancel out this gain [2]. Many crackers, each a little cleaner, can still pollute more than fewer old ones.

• Legal permission makes bursting look acceptable again, so more people may burst.

• Joined crackers make the problem bigger

• A lari sets off a long chain of crackers in one go. The 2018 judgment banned laris for this reason [1].

• The latest order allows next-generation joined green crackers [1]. So the most polluting form is back, only with a cleaner label.

• The timing makes even a small amount worse

• Crackers are burst when cold, still air is already trapping dust, vehicle smoke and stubble smoke [1].
• Smoke added at this point does not spread out. That is why 2025 reached an hourly peak of 675 µg/m³ even with green crackers [1].

9. Who Checks the 'Green' Claim? Mostly the Body That Made It

• The developer is also the tester
• CSIR-NEERI designed the green crackers [1]. An interim (early, not final) CSIR-NEERI report says the second-generation crackers cut PM10 and PM2.5 by 45–60% [5].
• PM10 means particles up to 10 micrometres wide. PM2.5 particles are smaller and go deeper into the lungs.

• No independent body has confirmed this interim figure [5].

• There is no fixed starting number to compare against

• Down To Earth pointed out that there is no standard figure for how much normal crackers emit. So any 'per cent less' claim is hard to check [3].

• The official record is silent, not reassuring

• In December 2022 the government told Parliament there was no evidence linking poor air in NCR to green-cracker burning [6].

• 'No evidence' here means the link was not measured. It does not prove green crackers are safe.

• The lists are only as good as the market checks

• NEERI and PESO (Petroleum and Explosives Safety Organisation, the licensing body for explosives) keep lists of approved products and makers [4].
• A list on paper does not stop a shopkeeper from selling an old cracker in a green-looking box.

10. The Trial Failed Its Own Test, Yet the Rule Was Widened

• 2025 was meant to be a trial
• The Court allowed NEERI-approved green crackers for only five Diwali days, with time limits. It kept its final decision pending [4].

• The stated aim was to watch the impact and then decide whether to continue [4].

• The result was bad, but the rules were loosened anyway

• Post-Deepavali PM2.5 averaged 488 µg/m³, the worst since 2021 [1].

• Instead of tightening, the next order added joined crackers [1].

• Even the Court had doubts

• While allowing the trial, the Court itself noted that short-term steps like green crackers had not clearly cut pollution before [4].
• A trial only helps if its result changes the decision. Here it did not, so the trial did not really test anything.

11. The Best Case Against a Ban, and Where It Falls Short

• The strongest argument for allowing crackers
• Crackers are not the main cause of Delhi's winter smog. Dust, vehicles, stubble burning and still cold air are [1].
• A ban hits a festival and the jobs of licence holders. The Court relaxed the rules in 2017 partly for these livelihoods [1].

• So, the argument goes, banning crackers punishes culture while the real polluters carry on.

• What this argument gets right

• A ban alone will not clean Delhi's winter air. Without action on stubble, vehicles and dust, the baseline stays 'severe' [1].

• Where it falls short

• 'Not the main cause' is not the same as 'harmless'. Crackers add a sharp spike on the worst days of the year [1].
• The harm falls on people who did not choose it, such as children and the elderly, while the pleasure goes to those who burst crackers.
• The livelihood problem can be met with help for workers to move to other work. Keeping a polluting product legal is not the only answer.

12. What Should Change Before Next Deepavali

• CPCB should test crackers bought from shops, not only lab samples
• Today the main emission numbers come from CSIR-NEERI's own interim report [5].

• CPCB (Central Pollution Control Board) could buy crackers from the open market and test them. That would show whether the claimed 45–60% cut is real [5].

• The Court should fix a clear pass mark before any trial

• For example, the Court could decide in advance what PM2.5 level counts as failure.

• In 2025 no such mark was set, so a 488 µg/m³ result still led to more relaxation [1][4].

• NEERI and PESO should publish their lists and make retailers prove their stock

• The lists of approved products already exist [4]. Police in NCR states need them to seize fake 'green' stock at the shop.

• The issue belongs inside year-round airshed planning

• Since crackers only add a spike on top of baseline pollution [1], the Commission for Air Quality Management should handle cracker rules together with stubble, dust and vehicle controls, instead of leaving them to one court order each festival.

16. NCERT Concepts to Revise

• Particulate matter (Geography): The article's key numbers (488 and 675 µg/m³) are PM2.5 readings; you need to know what PM2.5 is.
• Right to a clean environment (Polity): The court's cracker orders rest on balancing the Article 21 right to clean air against cultural sentiment.
• Judicial activism (Polity): Years of Supreme Court orders suspending, relaxing and restoring cracker rules show courts stepping in to run environmental policy.
• Graded Response Action Plan (Geography): This is Delhi-NCR's main emergency system for winter pollution, which the note treats as the larger problem.
• Commission for Air Quality Management (Geography): It is the statutory body that should coordinate airshed-wide action, instead of festival-specific court orders.
• Stubble burning (Geography): It is a major cause of winter smog, showing crackers are not the main source.

17. Common Errors / Trap Areas

• The case name: it is Arjun Gopal vs Union of India (2018). Do not mix it up with the MC Mehta vehicular pollution cases [1].
• 2016 vs 2018: 2016 was a licence suspension. 2018 was the green-only, no-laris, two-hour-window regime [1].
• "Green" does not mean zero-emission. These are reduced-emission crackers, and 2025 PM2.5 was still the highest since 2021 [1].
• Agency: green crackers came from CSIR-NEERI, not CPCB or MoEFCC [1].
• Main cause of pollution: crackers produce an acute spike. Baseline winter pollution comes mainly from dust, vehicles, stubble burning and meteorology [1].
