Shina Ansari, head of the organization, said the effort was carried
out with knowledge-based companies in coordination with the Ministry of
Petroleum. She highlighted additional initiatives, including phasing out old
vehicles and replacing 20,000 worn-out motorcycles in Tehran with electric
models, as part of a broader plan to improve air quality.
Ansari also noted that while mobile sources are the main contributors
to pollution in Tehran and Mashhad, stationary sources like power plants in
cities such as Arak remain significant. The supply of low-sulfur fuel has
helped reduce the number of unhealthy air days caused by sulfur dioxide from 27
days in 2023 to just five days in 2024.
Plans are underway to expand desulfurization of mazut at domestic
refineries, and efforts are ongoing to reduce gas flaring in oil-rich
provinces, including Khuzestan and Bushehr.
