With toxic air and rising health crises, Tehran’s suffocating smog exposes the regime’s systemic failures — from burning mazut to censoring pollution data.

Tehran has been ranked as one of the most polluted city in the world, with an air quality index (AQI) of 157 — a level considered hazardous to human health. While independent monitoring platforms publish alarming data, the regime of Ali Khamenei continues to censor air pollution reports, silence journalists, and block access to real-time tracking apps. For millions of residents, every breath has become a silent battle for survival.

A City Choked Under a Toxic Sky

In recent weeks, Tehran’s skyline has turned into a gray haze. The city now follows Delhi, Kuwait City, Lahore, Baghdad, and Tashkent on the global pollution chart.
While government-controlled media remain silent on the causes, independent analysts and environmental experts point to the same conclusion: the pollution crisis is not a natural phenomenon — it is a political one, born of decades of mismanagement and neglect.

Root Causes of Tehran’s Air Pollution

1. Burning Mazut: Poison in the Power Plants

Iran’s power stations continue to burn mazut — a highly sulfurous, low-quality fuel — to compensate for natural gas shortages caused by chronic mismanagement.
Reports by the Department of Environment show that this practice releases vast amounts of fine particulate matter (PM2.5) into the air, making Tehran’s winter skies a toxic blanket of industrial smoke.

2. Aging Vehicle Fleet and Poor-Quality Fuel

Tehran’s streets are clogged with more than four million outdated vehicles and carburetor-based motorcycles. Instead of renewing the transport fleet or enforcing emissions standards, the regime distributes cheap, low-grade gasoline. The result: a 30% rise in airborne particulates during the month of Aban (October–November).

3. Traffic Mismanagement and Institutional Privilege

Tehran’s traffic-control schemes have repeatedly failed. Exemptions granted to government institutions and security bodies undermine existing regulations. Meanwhile, limited metro capacity forces millions to rely on cars. Each day, millions of liters of fuel are burned inefficiently, turning congestion into an environmental catastrophe.

The Human Toll

The public health consequences are devastating. Hospitals report surging cases of asthma and chronic respiratory disease among children.
According to Tehran University of Medical Sciences, lung cancer rates in the capital are now twice the global average. Thousands die each year from pollution-related causes, yet officials describe these deaths as “natural.”

For families, the crisis is not abstract: children wheeze through the night, schools close intermittently, and outdoor activity becomes dangerous for the elderly and pregnant women.

Censorship Instead of Solutions

Instead of confronting the crisis, the regime tightens information control. Authorities have reportedly blocked access to air-quality apps and filtered VPNs that allow users to view real-time pollution data. Independent journalists who report on environmental issues face harassment or arrest.

This censorship mirrors the regime’s broader strategy: conceal systemic failure behind propaganda and repression, even when the cost is public health.

The Right to Breathe

The suffocating air over Tehran is not an act of nature — it is the direct consequence of a government that sacrifices public welfare to maintain control and cover up incompetence.
Tehran’s residents have a simple, universal demand: the right to breathe clean air and to know the truth about what poisons their children’s lungs.

Until that demand is met, the smog over Tehran will remain both a literal and symbolic expression of life under a regime that has polluted every aspect of society — from the air people breathe to the information they receive.
