The Winter Fog That Isn’t Just Fog
Picture this: It’s a chilly November morning in Delhi. The sun is trying to peek through a dense grey
haze that looks like someone accidentally left the smoke machine on at a neighborhood wedding.
You take a deep breath—mistake. Your lungs immediately regret the decision. Welcome to Delhi’s
annual AQI apocalypse.
On one particularly “normal” Monday, the Air Quality Index (AQI) decided to make a headline-worthy
jump to a hazardous 488 on average. For context, 488 is like putting your face directly into a bonfire
and breathing deeply. Some private monitors even reported numbers over 1,000—Delhi was essentially
competing with volcanic eruptions.
But here’s the kicker: We know this is coming every year. It’s not a surprise, like the sudden downpour
that ruins your freshly laundered clothes on the line. Yet, despite all the crores spent on monitoring,
analysis, and “tech-driven solutions,” the needle barely moves on tackling these severe pollution
episodes.
Blame the Smoke Signals
Sure, stubble burning often gets the limelight—and let’s be fair, it’s an easy villain. Farmers in Punjab
and Haryana torch their post-harvest fields to clear them for the next sowing. The smoke hitches a ride
on Delhi-bound winds, joining forces with local pollutants. But guess what? This year, satellite data
claimed that stubble fires were down by 30%. And yet, Delhi’s air still hit “apocalypse now” levels.
The System of Air Quality and Weather Forecasting And Research (SAFAR) data shows that stubble
burning contributed around 17% to Delhi’s PM2.5 levels this year, down from nearly 30% in previous
years. Yet, household emissions and road dust stepped in to fill the gap. These chronic contributors are
often overlooked because their impact is spread over time, like a slow poison rather than a sudden
disaster.
The Curious Case of the Toothless Commission
Enter the Commission for Air Quality Management (CAQM), a body set up to coordinate pollution-
control efforts across Delhi and its neighbors. Sounds good on paper, right? Except it often feels like
a referee who shows up only after the match has descended into chaos. It mostly sits silently unless
dragged to court by an exasperated Supreme Court, leaving everyone wondering if it’s truly empowered
or just an awkward spectator.
Meanwhile, Delhi’s ministers are busy finding creative excuses. Faulty satellite data? Check. Proposals
like “cloud seeding” to manufacture rain and wash away pollutants? Double-check. The central
environment ministers are off attending international conferences or managing election campaigns.
The metaphorical house is on fire, and everyone is either pointing fingers or hosting webinars on how
to use the extinguisher.
Dust: The Uninvited Guest That Never Leaves
Let’s talk about road dust for a moment—Delhi’s eternal roommate. If stubble burning is the rude
neighbor throwing occasional loud parties, road dust is the hoarder who’s been piling up junk in the
living room for years. According to the Delhi Pollution Control Committee (DPCC), road dust accounts
for nearly 42% of Delhi’s PM10 levels, making it a major culprit.
The city’s ever-expanding construction sites, poor road conditions, and lack of effective sweeping
mechanisms ensure that road dust remains a perennial problem. The National Green Tribunal has
repeatedly pulled up authorities for failing to implement dust-control measures like mechanized
sweeping and covering construction debris.
What’s the fix? Regular mechanized sweeping, stricter penalties for uncovered construction sites, and
green barriers can cut down dust. But here’s the thing: fighting dust doesn’t make for dramatic headlines
or photo ops, so it’s often ignored in favor of more visible interventions.
Vehicles: The Gas-Guzzling Giants
Vehicles contribute around 25-30% of Delhi’s PM2.5 levels. Despite the implementation of BS-VI fuel
norms and a push for electric vehicles (EVs), the sheer number of vehicles on Delhi’s roads—over 12
million—makes this a Herculean task.
While carpooling campaigns like “Odd-Even” have shown temporary results, sustainable solutions need broader adoption of public transport.
Imagine a Delhi with fewer cars and more buses, metro lines, and cycling tracks. Beijing tackled
vehicular emissions by replacing all diesel buses with electric ones, slashing pollution by 40%.
If they can do it, why can’t we?
The Meteorological Wildcard
Even with the best policies, Delhi’s geography and weather conspire to keep pollution levels high.
During winters, cooler temperatures and low wind speeds create an inversion layer, trapping pollutants
close to the surface. The Indian Institute of Tropical Meteorology (IITM) estimates that during these
episodes, local sources account for up to 60% of pollution.
It’s like nature hitting the pause button on pollution dispersal. This makes local interventions—road
dust management, better waste disposal, and public transport—all the more critical.
Rising Above the Haze
If this annual pollution saga teaches us one thing, it’s that Delhi’s air doesn’t improve unless the state
and center get serious about working together—and communicating their efforts effectively. A crisis this
persistent needs more than a reactive “pollution season” playbook. It needs bold actions, year-round
commitment, and leaders willing to say, “No, cloud seeding isn’t going to save us.”
Imagine if instead of bickering, leaders united like an Avengers team for the environment. What if the
CAQM had more independence to enforce long-term measures, like stricter construction dust control or
urban greening initiatives? What if governments actively engaged citizens, showing them how their
actions—like carpooling or reducing waste burning—could make a difference?
A Breath of Fresh Air...Someday?
Until then, Delhiites continue their annual winter ritual: checking AQI apps, debating over masks versus
air purifiers, and watching as hazy skies become the city’s new normal. But maybe, just maybe, the first
step out of this smog isn’t technology or politics—it’s everyone realizing that we’re all breathing the same
air.
So, the next time someone talks about AQI, remind them: fixing Delhi’s air isn’t rocket science—it’s
street-level, grassroots, year-round hard work. Let’s aim for a winter where the only thing choking us
is the fog of nostalgia—and not a literal fog that makes you wish you had gills.
Case Studies & Practical Solutions: Breathing Room for the Capital

Although Bengaluru is primarily battling its own pollution issues, its urban forest programs offer
valuable insights. Through public-private partnerships, the city created several mini-forests in unused
spaces.
Actions Taken:
Conducted large-scale tree-planting drives using native species.
Converted barren lands and landfills into community parks.
Engaged local communities in tree adoption programs.
Outcome:
Improved local air quality and reduced urban heat islands.
Enhanced biodiversity in urban areas.
Takeaway for Delhi: Encouraging rooftop gardens, tree plantations, and urban forests could serve as low-cost, high-impact
solutions.
A Vision for the Future
Imagine a Delhi where the AQI stays below 100 year-round, where the Metro is the preferred mode of
commute, and where roads are lined with trees rather than dust. This vision isn’t pie-in-the-sky; it’s
achievable with consistent effort, political will, and public cooperation.
As we breathe through our masks and wait for clearer skies, let’s remember: every small action—whether
it’s using public transport or planting a tree—adds up. The fight for clean air isn’t just the government’s
responsibility; it’s everyone’s battle. And together, we can give Delhi a winter where we savor the nip in
the air without the bite of pollution.
