What is causing poor air quality in Riyadh?
Riyadh’s polluted air results from a mix of natural and human‑driven sources. Frequent desert dust and sandstorms lift large amounts of particulate matter into the atmosphere, contributing to elevated PM10 levels (1).
Rapid urbanization and heavy reliance on private vehicles generate significant emissions of nitrogen oxides and fine particles. Industrial activities and energy sector emissions add to the pollution burden, while construction and cement production contribute additional particulates (2).
The city’s arid climate and stagnant conditions further hinder dispersion, trapping pollutants at ground level.
