Smog Theatre’: The Alarming Truth Behind Lahore’s Anti-Smog Guns and Towers

As Lahore battles another smog season, expensive anti-smog guns and towers branded as “Climate Resilient Punjab” promise clean air. But are these machines real solutions or just smog theatre? Discover the science and policy behind Pakistan’s air crisis.

Smog Theatre has become an alarming reality in Pakistan’s second-largest city. As Lahore gears up for another suffocating smog season, an imposing fleet of green trucks roams the streets — each equipped with a giant rotating cannon spraying a fine mist into the air.

Promoted under the “Climate Resilient Punjab” banner, these anti-smog guns promise cleaner skies and visible action. Yet, behind the misty spectacle lies a troubling truth — these machines may look powerful but deliver little in the fight against air pollution.


What Are Anti-Smog Guns?

The government’s anti-smog initiative features high-pressure fog cannons imported from China. Each truck-mounted cannon releases a mist of water droplets intended to “settle” airborne dust and particulate matter (PM2.5).

According to officials, the Punjab Environmental Protection Agency (EPA) has deployed at least 15 units across Lahore’s high-traffic zones. The goal is to visibly reduce haze levels and improve public perception of government action on pollution.

However, environmental scientists warn that these devices are symbolic rather than scientific.


The Science Behind the Spray

While the mist looks impressive, the science says otherwise.

A 2023 peer-reviewed study in China found that areas treated with water cannons experienced a 13% increase in PM2.5 levels about 30 minutes after spraying. The reason? Added moisture accelerated chemical reactions that formed more fine particles instead of removing them.

In other words, the fog cannons didn’t clean the air — they made it worse.

This effect, known as “secondary aerosol formation,” highlights how quick fixes can backfire when they ignore atmospheric chemistry.

The High Cost of Fog Cannons

Each fog cannon costs over Rs45 million, according to multiple news reports. Operating one machine for 24 hours consumes nearly 360,000 litres of water per day — an astonishing figure for a city already facing chronic water stress.

Multiplied across multiple units, this creates an enormous financial and environmental burden.

Instead of targeting the root causes of pollution — vehicle emissions, industrial smoke, and waste burning — these resources are being spent on performative displays that look like progress but change nothing.


Why Smog Theatre Persists

Why does Smog Theatre continue despite scientific evidence against it? The answer lies in politics and perception.

During public health crises, governments face immense pressure to appear proactive. The towering cannons spraying mist across Lahore serve as a visual reassurance, a message that “something is being done.”

This phenomenon, dubbed “Smog Theatre,” prioritizes optics over outcomes. It’s a performance of action — a political spectacle designed to capture attention, not clear the air.

Last year’s smog towers, installed amid media fanfare, failed to make any measurable dent in pollution levels. Yet, similar technologies keep returning under new names and slogans.


What Lahore Really Needs

Lahore’s smog crisis stems from a complex web of sources:

  • Vehicle exhaust (diesel trucks, motorbikes)
  • Industrial combustion (factories, brick kilns)
  • Construction dust and open waste burning
  • Seasonal crop residue fires

To combat these, experts recommend evidence-based interventions rather than atmospheric theatrics:

  • Stronger vehicle emission standards and fuel quality enforcement
  • Modernization of brick kilns to zigzag technology
  • Public transport investments to reduce private car use
  • Real-time air quality monitoring and public data access

The World Health Organisation (WHO) recorded zero clean air days for Lahore in 2024. Average PM2.5 levels reached 104.6 µg/m³, 21 times higher than the WHO safety limit.

This isn’t a seasonal issue — it’s a year-round public health emergency.


Learning from China’s Success

China once faced a similar crisis. Cities like Beijing and Shanghai recorded some of the world’s worst air pollution levels. But over a decade, China reversed the trend through a data-driven approach:

  • Building comprehensive emissions inventories
  • Enforcing industrial emission standards
  • Closing high-emission factories
  • Promoting clean energy and electric vehicles
  • Implementing real-time air monitoring

As environmental economist Ma Jun notes in The Economics of Air Pollution in China, success came from evidence, not theatrics.

Pakistan can follow this model — but only if it stops misting symptoms and starts addressing causes.


Conclusion: From Optics to Outcomes

The Smog Theatre unfolding in Lahore reflects a broader governance challenge. The focus remains on short-term optics rather than long-term outcomes.

Instead of investing millions into fog cannons and smog towers, these funds should power enforcement, research, and education — the pillars of sustainable air management.

Cleaner air won’t come from mist or machines that make headlines. It will come from consistent regulation, public awareness, and cross-sector cooperation.

Lahore doesn’t need to look clean; it needs to be clean.
