Air pollutants is the newest environmental disaster inflicting havoc throughout Iran. Huge portions of the rustic are already affected by a drought, one of the vital worst in a long time. Its wetlands are dry, and its land is subsiding at alarming charges.
Now the fallout may be affecting the air that the rustic’s extra than 85 million other people breathe. As lakes, wetlands, and riverbeds dry out, their uncovered surfaces grow to be primary resources of mud. Robust winds can carry this mud and shipping it throughout towns or even far-off areas.
The extraordinarily dry stipulations have worsened Iran’s already excessive ranges of air pollutants. In contemporary weeks, the capital Tehran was once ranked as essentially the most polluted town on the earth, consistent with world air high quality displays. In November, its air high quality index hit 200 – a degree categorized as “very unhealthy”.
The horrible air high quality has compelled government to near faculties, universities and places of work to scale back publicity. Hospitals are reporting emerging numbers of instances of respiration and cardiac headaches around the nation.
Native media have reported greater than 350 deaths inside of ten days related to worsening air high quality in contemporary weeks. Call for for emergency services and products within the capital has additionally greater by means of greater than 30% all the way through November 2025, consistent with native statistics.
Different primary Iranian towns, together with Tabriz, Mashhad and Isfahan, have recorded readings above 150 in the previous couple of weeks. Those ranges are thought to be bad for all age teams. In Ahvaz and Zabol, air pollutants from sand and dirt storms has blanketed the southern towns, placing lives and livelihoods in danger.
Research point out greater than 59,000 Iranians die upfront once a year from air pollution-related sicknesses.
In addition to mud emerging from dried out lakes and wetlands, getting old automobiles and low-quality gasoline in Iran’s primary towns are contributing to the air pollutants.
However that specialize in those reasons misses the larger image.
Iran’s air-pollution emergency is led to by means of the similar governance screw ups that experience destabilised the country’s water programs, emptied its aquifers, dried out its wetlands, and sped up land subsidence.
Simply as Iran’s water disaster isn’t merely the results of drought, Iran’s polluted air isn’t merely the manufactured from site visitors.
In maximum primary towns, a key burden comes from pollution (akin to nitrogen oxides, sulfur dioxide, and wonderful particulates produced by means of burning low-quality gasoline) in addition to out of date engines, and heavy commercial fuels akin to mazut.
Those poisonous emissions gather in towns and without delay give a contribution to respiration illness, and cardiovascular sickness. Fresh world satellite tv for pc analyses, which can be these days being reviewed by means of the magazine Nature Towns, counsel that almost all mega towns (inhabitants greater than 10 million) with vital ranges of nitrogen dioxide pollutants within the decrease environment (the layer of air we breath) have lower pollutants ranges in recent times.
How Tehran’s citizens are coming with the drought.
On the other hand, Tehran is one of the few massive towns international the place those concentrations have greater between 2019 and 2024.
However combustion engines in previous automobiles are handiest part the tale. In lots of areas, a considerable percentage of PM₁₀ and PM₂.₅ (debris smaller than 10 micrometers and a couple of.5 micrometers which penetrate the lungs and bloodstream) now originates from mud and salt storms generated by means of shrinking lakes, rivers and wetlands. Those debris can commute masses and even hundreds of kilometres inside of hours, affecting towns a long way past their issues of starting place.
Our analysis, on Lake Urmia – as soon as the Center East’s greatest saltwater lake – presentations this obviously: because the lake mattress dried, salt-laden mud plumes have been in a position to travelling masses of kilometres or even crossing nationwide borders in not up to 12 hours. This can be a bright representation of the way tightly Iran’s water disaster is intertwined with its air-pollution disaster.
Key reasons of Iran’s air pollutants
Iran’s air-pollution downside isn’t just a shipping downside, a technological shortfall or a meteorological misfortune. It’s basically the predictable end result of a long time of presidency priorities, distorted incentives, and institutional inertia.
First, Iran’s executive priorities have formed a international coverage that in the long run resulted in global sanctions and deepened the rustic’s financial and global isolation.
This isolation has had direct environmental penalties. It restricts get admission to to trendy air‑high quality tracking programs, commercial filtration applied sciences, and coffee‑emission engines, whilst deterring the international funding had to improve shipping and business.
Because of this, whilst different international locations have decreased NO₂ and particulate pollutants thru cleaner applied sciences and tighter requirements, Iran’s choices stay significantly restricted by means of the political alternatives that produced its isolation.
2d, Iran’s extraordinarily low gasoline costs, sustained by means of immense subsidies, have made the nationwide economic system depending on affordable power, a key driving force of the rustic’s inefficient electrical energy technology and over the top intake. Automobiles with gasoline inefficiencies unattainable in different places stay commercially viable.
This isn’t an unintentional coverage end result. It is a part of a broader financial cycle through which subsidised gasoline sustains out of date home automobile manufacturing and high-emitting industries, a few of which can be tied to tough establishments whose monetary pursuits rely on keeping up the established order.

Resetting nationwide priorities
Many nations have lower city pollutants thru stricter emissions requirements, cleaner shipping, and built-in town making plans, however Iran can not do that with out addressing the structural forces riding its emissions.
Reversing Iran’s air-quality disaster calls for a basic shift in executive priorities, hanging environmental safety and public well being on the centre of policymaking. Iran’s problem isn’t technical capability however distorted incentives and nationwide priorities. Simplest by means of lowering global isolation, strengthening transparency, and dismantling subsidy-driven distortions can Iran release the applied sciences and funding had to blank its air.
As soon as those structural boundaries are addressed, actual growth turns into conceivable. This would come with step by step converting gasoline costs to curb high-emission automobiles, restoring get admission to to world generation and finance to modernise the automobile fleet and public shipping, and reviving wetlands, lakes, and soils thru water-governance reform to chop mud pollutants.
Complementing those measures with complex satellite tv for pc tracking, AI-based research, air tracking stations, and higher city planing.
The air isn’t polluted as a result of Iranians pressure an excessive amount of – it’s polluted since the device that shapes the rustic’s priorities and alternatives is damaged.
