What is happening on 29 October
The Supreme Court is scheduled to hear on Thursday, 29 October 2026, matters concerning rising pollution in Delhi and the National Capital Region (NCR), stubble burning and the sale of so-called green firecrackers ahead of Diwali. The hearing was reported by the news agency IANS on the morning of 29 October, and the listing was also flagged in national headline round-ups for the day.
That timing is the point. The court is not being asked to settle Delhi's air quality problem in one sitting. It is being asked, just before the festival season, to decide how much room — if any — there should be for firecrackers in a region whose air is already deteriorating, and what the governments involved must do about the other sources of pollution that arrive at the same time every year.
Readers should be careful about one thing from the start: at the time of writing, the hearing is listed for today, and no final order from today's proceedings has been reported in the sources used for this article. What follows explains what is already on record, what the court has signalled in earlier hearings, and what to watch for — not a decision that has not yet been made.
Why Delhi's air is in the news again
Delhi's air quality deteriorated to the poor category on Wednesday, 28 October, ending a four-day run of moderate air quality, according to reporting of Central Pollution Control Board (CPCB) data. The city's average Air Quality Index (AQI) rose to 229 on Wednesday from 197 on Tuesday.
The CPCB scale used in that reporting puts 0 to 50 in the good category, 51 to 100 as satisfactory, 101 to 200 as moderate, 201 to 300 as poor, 301 to 400 as very poor and 401 to 500 as severe. On Wednesday, out of 58 monitoring stations in Delhi, 16 recorded moderate air quality, 41 recorded poor air quality and one — Vivek Vihar, at 316 — recorded very poor air quality.
In other words, Delhi is entering the festival period already in the poor band, before the usual post-Diwali spike. That is why a courtroom remark on Wednesday drew attention. During a hearing, Justice Vikram Nath observed that while lawyers can work from home to avoid polluted air, judges must attend court in person. The remark came as senior advocate Indira Jaising sought a listing on 17 November, after Diwali, in an unrelated matter, and the opposing counsel pressed for an earlier date, citing worsening air around the festival. Justice Nath responded that the air in Delhi would be very bad after Diwali. The exchange, reported by multiple outlets on 28 and 29 October, captured in a single sentence the seasonal pattern the pollution case is about: air that is already poor gets worse after the festival, and the people who must keep working through it cannot simply opt out.
What the court has already decided — and what it has not
Under an earlier Supreme Court order made to address air pollution in Delhi-NCR, the manufacturing, storage and use of all types of firecrackers remain completely prohibited, according to the IANS report of 29 October. That blanket position is the starting point for today's hearing.
At the previous hearing, however, the court indicated that a limited relaxation was possible. It allowed firecracker manufacturers to produce green firecrackers for the Delhi-NCR region, while making it clear that permission to manufacture would not automatically allow their sale. The question of permitting sale was left open, and it is expected to remain an important part of the proceedings ahead of Diwali.
That distinction — manufacture versus sale — matters, and it is easy to misunderstand. A factory being allowed to make a product does not mean shops can sell it, or that residents can burst it. Until the court says otherwise, the sale question is undecided. Anyone reading a claim that green crackers have been fully cleared for Diwali in Delhi-NCR should treat it with caution unless it cites a specific, current court order.
The court has also directed the Central Government to consult all relevant stakeholders and work towards a balanced policy on the manufacturing and use of firecrackers in Delhi-NCR. In earlier observations reported alongside the listing, the court said public awareness and voluntary participation would be more effective in addressing firecracker-related pollution than restrictive orders that could be difficult to enforce on the ground. That is a significant signal: the court appears to be weighing not only what the law should say, but what can actually be enforced in a city of millions during a festival.
What are green crackers?
Green crackers are firecrackers developed to emit less smoke and fewer harmful chemicals than conventional crackers. They are generally certified through a system involving the Council of Scientific and Industrial Research — National Environmental Engineering Research Institute (CSIR-NEERI), which tests formulations for reduced emissions. Reports on the current proceedings note that the Centre has presented proposals for less-polluting crackers, including studies on reducing the use of barium and on cutting emissions.
That does not make them pollution-free. Even a lower-emission cracker still releases particulate matter and gases, and in a city already in the poor AQI band, the cumulative effect of large numbers of crackers burst over a short period can still push readings sharply higher. The debate before the court is therefore not simply green versus conventional. It is whether any crackers, even cleaner ones, should be allowed in a region where the baseline air is already unhealthy, and if so, under what controls — for example, limits on timing, on the types permitted, or on where they can be sold and used.
The court has not, in the material available before today's hearing, announced such a detailed regime for this Diwali. That is precisely what today's hearing may clarify, defer, or leave to the governments to propose.
Stubble burning: the other half of the case
Firecrackers dominate the headlines, but the hearing also covers stubble burning — the practice of burning crop residue in fields, mainly in Punjab and Haryana, after the paddy harvest. Smoke from these fires is carried by north-westerly winds towards Delhi, and it typically coincides with the onset of winter, when cooler air and calm winds trap pollutants close to the ground.
Stubble burning is therefore not a side issue in this case. It is one of the reasons Delhi's air worsens at exactly this time of year, alongside local emissions from vehicles, dust, construction and industry. Any order that deals only with crackers, without addressing farm fires and enforcement in neighbouring states, would leave a large part of the seasonal problem untouched. That is why the case brings together the Centre, the Delhi government and neighbouring state governments, and why the court has in the past sought affidavits and action plans from several of them.
For farmers, the issue is practical as much as environmental: clearing fields quickly between the paddy harvest and the wheat sowing window, with limited machinery and tight margins. For Delhi residents, it is a health issue that arrives regardless of what any individual household does. The court proceedings sit at the intersection of those two realities, which is one reason a lasting solution has proved so difficult.
Why enforcement has been so hard
One recurring theme in this litigation is the gap between an order and its implementation. The court has previously expressed concern that bans were not implemented on the ground, with widespread reports of firecrackers being burst despite prohibitions. A ban that is widely ignored does not clean the air, but it does undermine confidence in the court's directions and in the agencies meant to enforce them.
That enforcement problem shapes the choices before the court. A complete ban is clear on paper but hard to police across a vast urban region during a festival. A regulated allowance — for example, permitting only certified green crackers, for limited hours, through licensed sellers — might be easier to monitor, but it still requires checking that what is sold is genuinely green, that unlicensed sellers are stopped, and that the overall load does not overwhelm an already poor air day. A third option, deferring the sale decision while seeking a fuller policy from the Centre, avoids a rushed ruling but leaves traders, manufacturers and residents uncertain days before Diwali.
None of these options is cost-free. Manufacturers who were allowed to produce green crackers need to know whether they can sell them. Traders need to know whether to stock them. Residents who want to celebrate need clear, timely information, not rumours. And people with asthma, heart conditions, young children or elderly family members need to know whether to expect a sharp deterioration and plan accordingly. Today's hearing matters because it should, at minimum, reduce that uncertainty, even if it does not settle every question.
What this means for residents
For most people in Delhi-NCR, the practical implications are straightforward, and they do not depend on guessing today's outcome.
First, do not assume that green crackers are already legal to buy or burst in Delhi-NCR. Until a current court order or government notification says so clearly, the earlier prohibition on manufacture, storage and use remains the baseline, with only the limited manufacturing relaxation described above.
Second, check the AQI for your area, not just the city average. On 28 October, the city average was 229, but Vivek Vihar was already at 316, in the very poor band. Local readings can differ sharply, and people with respiratory conditions should plan around the worst nearby reading, not the average.
Third, the usual health precautions for poor-air days still apply: limit prolonged outdoor exertion when the AQI is poor or worse, keep windows closed during peak pollution hours where possible, use masks outdoors if advised by health authorities, and keep prescribed inhalers and medicines accessible. These are general precautions, not a substitute for medical advice, and anyone with breathing difficulty should seek medical help promptly.
Fourth, be sceptical of social media claims about the hearing. A headline saying crackers are "allowed" or "banned" may be describing only one part of the order — manufacture, sale, or use — or may be repeating an older order. Look for the specific permission, the dates and hours it covers, and the authority that issued it before acting on it.
What to watch after today's hearing
Three questions will tell readers what actually changed after 29 October.
One, did the court permit the sale of green crackers in Delhi-NCR, and if so, with what conditions on type, timing, sellers and enforcement? A permission to manufacture alone would be no change from the previous position.
Two, what did the court say about stubble burning and the responsibilities of the Centre and the neighbouring states? Directions on monitoring, penalties or support for alternatives would signal whether the court is treating this as a festival-only issue or a seasonal air-quality issue.
Three, did the court set a timeline for a balanced, longer-term policy on firecrackers, as it had earlier asked the Centre to develop with stakeholders? A clear timeline would matter more for next year than for this Diwali, but it would show whether the court intends to keep returning to the same question every October.
If today's hearing is adjourned without a clear order on sale, that too is information: it would mean the existing prohibition remains the operative position, and traders and residents should not act as if a relaxation has been granted.
Conclusion
The Supreme Court's hearing on 29 October 2026 is, at its core, a test of how to balance three things that do not easily fit together: a festival tradition, a public health emergency that returns every winter, and the practical limits of enforcement. Delhi's air is already poor, with a city average AQI of 229 on 28 October and at least one station in the very poor band. The court has allowed the manufacture of green crackers but has not yet allowed their sale. It has asked the Centre to build a balanced policy with stakeholders, and it has warned, in its own words, that the air after Diwali will be very bad.
Whatever the court decides today, the larger problem will not end with Diwali. Stubble burning, vehicle and dust emissions, and winter weather will still shape Delhi's air in November and December. A clear, enforceable order — whether it permits regulated green crackers or keeps the ban — would at least give residents, traders and governments something firm to work with. Until that order is actually issued and reported in full, the safest reading of the position is the one already on record: manufacture of green crackers has been permitted, sale has not, and the hearing on 29 October is where that question comes back before the court.
Frequently Asked Questions
### What is the Supreme Court hearing on 29 October 2026 about?
It concerns rising pollution in Delhi-NCR, stubble burning and the sale of green firecrackers ahead of Diwali. The court is scheduled to consider firecracker manufacturing and use, along with other steps to curb pollution during the festive season.
### Are green crackers allowed in Delhi-NCR for Diwali 2026?
Not on the basis of the record available before today's hearing. The court had allowed manufacturers to produce green firecrackers for Delhi-NCR, but it made clear that this did not automatically allow their sale. Whether sale is permitted is a key question for the 29 October hearing, and readers should wait for the actual order before assuming it is allowed.
### How bad is Delhi's air right now?
Delhi's average AQI was 229 on 28 October 2026, in the poor category, up from 197 the previous day, according to CPCB data reported by Times Now. Of 58 stations, 41 were poor, 16 moderate and one, Vivek Vihar at 316, was very poor. The CPCB bands are: 0-50 good, 51-100 satisfactory, 101-200 moderate, 201-300 poor, 301-400 very poor and 401-500 severe.
### What is stubble burning, and why does it matter for Delhi?
Stubble burning is the burning of crop residue left in fields after harvest, mainly in Punjab and Haryana. Smoke is carried towards Delhi by seasonal winds at a time when cool, calm winter air traps pollutants near the ground, so it contributes to the sharp deterioration in Delhi's air quality around Diwali and into November.
