applying an ointment to a fracture
Each winter, Delhi's skies darken under a weight of particulate matter that no emergency protocol has yet managed to lift. The city's Graded Response Action Plan — a staged system of restrictions triggered by worsening air quality — offers the appearance of decisive action while leaving the deeper architecture of the crisis untouched. Environmental researchers argue that without confronting the sources of pollution directly, from fossil-fuel dependence to agricultural burning to industrial impunity, Delhi is destined to rehearse the same emergency, season after season, in a cycle that costs its residents their health and their breath.
- Delhi's PM10 levels reached 197 micrograms per cubic meter in 2025 — nearly three times the national standard — with dozens of monitoring stations recording very poor or severe air quality on ordinary winter mornings.
- GRAP's emergency restrictions, from shutting diesel generators to deploying traffic officers, create visible urgency but rest on an outdated emissions inventory with no reliable mechanism to confirm whether pollution loads are actually falling.
- The two analytical tools that could measure GRAP's effectiveness — a meteorological decision support system and a real-time source identification network — remain disconnected, leaving policymakers essentially flying blind.
- In November 2025, regulators tightened GRAP's trigger thresholds, activating curbs at earlier alert stages, but experts warn this is still crisis management dressed as prevention.
- Researchers are calling for a fundamentally different approach: airshed-level governance that transcends state politics, massive public transport investment, an end to biomass burning, and year-round accountability for industrial polluters.
Every winter, Delhi's air thickens and the government activates GRAP — a graded emergency protocol that tightens restrictions as the Air Quality Index deteriorates. Diesel generators go silent, traffic officers appear at choked intersections, government workers are sent home. The measures feel urgent. But environmental researchers say the city is treating a broken bone with ointment.
Sunil Dahiya, an environmental strategist with fourteen years studying pollution data, argues that GRAP has not produced meaningful reductions across Delhi and the surrounding National Capital Region. The plan relies on an outdated emissions inventory, and no system exists to verify whether its restrictions actually lower total pollution output. Two analytical tools are available but remain unconnected — leaving officials unable to know whether the protocol is working at all.
Bharati Chaturvedi of the Chintan Environmental Research and Action Group frames the failure in historical terms: GRAP was always meant to be temporary, a bridge while authorities built lasting solutions. Instead, the city has leaned on it year after year without constructing that bridge. She calls for genuine decongestion, expanded public transport, an end to agricultural and municipal waste burning, and monitoring systems with real enforcement power. Without looking beyond GRAP, she warns, Delhi will face the same crisis on the same calendar every year.
In November 2025, the Commission for Air Quality Management revised GRAP's thresholds, pushing restrictions into earlier alert stages so curbs activate sooner. The framework is more aggressive — but experts say it remains a response to catastrophe rather than a prevention of it. Harjeet Singh, a fossil-fuel transition advisor, compares the approach to fighting a forest fire with a garden hose. What Delhi needs, he argues, is governance at the scale of the entire airshed — overriding state-level politics, breaking the city's dependence on private fossil-fuel vehicles, and holding industrial polluters accountable not just in winter emergencies but throughout the year.
The numbers make the stakes plain. Delhi recorded the country's highest annual PM10 average in 2025, at nearly three times the national standard. Officials point to their ongoing reviews and stricter rules as evidence of progress. The researchers remain unconvinced — because tightening an emergency protocol cannot fix what the protocol was never designed to address: the sources of the pollution itself.
Every winter, Delhi's air turns thick and gray, and the government activates an emergency protocol called GRAP—the Graded Response Action Plan. Restrictions tighten in stages as the Air Quality Index worsens. Diesel generators get shut down. Traffic officers appear at congested intersections. Government workers are sent home. The measures feel urgent, necessary, and temporary. But environmental researchers who have spent years studying Delhi's pollution crisis say the city is treating a broken bone with ointment.
Sunil Dahiya, an environmental strategist with fourteen years of experience analyzing pollution data, puts it plainly: GRAP works as an emergency response, but it has not produced meaningful reductions in pollution levels across Delhi and the surrounding National Capital Region. The problem runs deeper than the policy's design. GRAP, he argues, relies on an emission inventory that is outdated, and there is no system in place to measure whether the restrictions actually lower the total amount of pollution being released into the air. Two tools exist—the Decision Support System developed by the Indian Institute of Tropical Meteorology, and a real-time source identification network called R-AASMAN—but they are not connected in a way that would let officials know if GRAP is working.
Bharati Chaturvedi, director of the Chintan Environmental Research and Action Group, frames the issue differently. GRAP, she says, was always meant to be temporary—a way to give residents breathing room while authorities tackled the underlying causes. That was the theory. In practice, the city has relied on GRAP year after year without building the infrastructure that would actually solve the problem. She calls for decongestion of the city, a genuine expansion of public transport, an end to the burning of agricultural waste and municipal garbage, and monitoring systems with real teeth. "If we do not look beyond GRAP," she told reporters, "the city will continue to face the same situation year after year." She also emphasized that pollution control agencies need stronger funding and that scientists working on these issues need clearer career paths.
In November 2025, the Commission for Air Quality Management tightened GRAP's rules, moving several restrictions to earlier alert stages so that curbs kick in sooner as air quality deteriorates. Measures that once triggered at Stage II now activate at Stage I. Staggered work hours for government offices, which previously began at Stage III, now start at Stage II. The revised framework is more aggressive, but experts say it is still a response to a crisis rather than a prevention of one.
Harjeet Singh, a strategic advisor focused on moving away from fossil fuels, uses a stark comparison: relying on GRAP is like trying to extinguish a forest fire with a garden hose. He calls for what he terms "uncompromising airshed-level governance"—a model that overrides state politics and demands massive investment in public transport. The real solution, he argues, is to stop managing pollution and start managing its sources. That means breaking the city's dependence on private cars powered by fossil fuels and holding industrial polluters accountable throughout the year, not just during crisis periods.
The numbers underscore the scale of the problem. In 2025, Delhi recorded the highest annual average concentration of PM10 particles in the country: 197 micrograms per cubic meter, nearly three times the national standard of 60. On a recent Wednesday morning, five of the city's 39 monitoring stations showed severe air quality, while thirty-two remained in the very poor category. When officials from the Commission for Air Quality Management respond to these criticisms, they point to their periodic reviews of GRAP and their efforts to make the measures more stringent. They say they are examining implementation on the ground and working to introduce stricter rules backed by stronger enforcement. But the experts remain unconvinced that tightening an emergency protocol addresses what the protocol was never designed to fix: the sources of the pollution itself.

GRAP is a well-designed policy and functions as an emergency response to some extent, but it has failed to bring about a significant reduction in pollution levels in Delhi— Sunil Dahiya, environmental strategist
GRAP should be phased out gradually, as it is akin to applying an ointment to a fracture. If we do not look beyond GRAP, the city will continue to face the same situation year after year— Bharati Chaturvedi, director of Chintan Environmental Research and Action Group

Why does GRAP keep coming back every year if it's been in place since 2017?
Because GRAP was always meant to be a temporary shield, not a cure. It buys time for residents to breathe easier while authorities supposedly work on long-term fixes. The problem is those long-term fixes never materialized. So now we have a band-aid that gets reapplied every winter.
What would actually fix it?
The sources themselves. You'd need to reduce the number of cars on the road through better public transport, stop agricultural burning in surrounding states, shut down unpermitted industrial operations, and decongest the city. These are expensive, politically difficult changes that take years. GRAP is fast and visible.
But hasn't the government made GRAP stricter? Doesn't that count for something?
It counts for something in the moment. Moving restrictions to earlier stages means people get relief sooner. But if you're not reducing the actual pollution being generated, you're just managing the symptoms more aggressively. It's still a garden hose on a forest fire.
Who bears the cost of waiting for these long-term solutions?
The people breathing the air. Especially children, elderly people, and those with respiratory conditions. Delhi's PM10 levels are three times the national standard. That's not a policy failure—that's a public health crisis happening in real time.
What would it take to actually move the needle?
Money, political will across state lines, and a willingness to disrupt how the city functions. You can't improve public transport without massive investment. You can't stop agricultural burning without working with neighboring states. You can't hold industrial polluters accountable without stronger agencies and enforcement. GRAP requires none of that. It just restricts what people can do when the air gets bad enough.
