In 2025, the West Asia region was represented by 103 cities across 14 countries and territories, reflecting a diverse and shifting air quality landscape. At the city level, trends were notably mixed: 54 cities saw an increase in annual average PM2.5 concentrations, while a similar pattern of fluctuation, with seven countries experiencing rising PM2.5 levels and four seeing a decline. Additionally, the regional dataset expanded to year shifts, most notably Kuwait. Its national annual average PM2.5 concentration rose by 51%, rising from 30.2 to 45.7 μg/m3, resulting in the highest annual PM2.5 average in the region. In contrast, Jordan Range of 2025 average PM2.5 (μg/m3) across regional cities entered the Report with the region's lowest national average at 14.8 μg/m3. Despite some improvements elsewhere, air pollution remains a concern for the area, as Kuwait, lraq, the United Arab Emirates, and uu jaun uun jaun euasouud jenu ka uan transportation emissions, construction, and industrial sources.Significant spikes in regional PM2.5 were attributed to intense dust storms, with cities across West Asia reporting peak concentrations during major events in April, May, and November. West Asia's monitoring network continues to expand, recently adding eight new cities across Armenia, Israel, Palestine, and Syria. While none of these newly included μg/m3, four of the eight recorded relatively moderate Despite this growth, the region's monitoring sensors, with nearly 70% of all air quality data provided by non-governmental sources. Currently, West Asia. accounts for only 1% of the total stations included in this year's Report-the smallest representation of any region globally. Expanding the availability of high- quality, publicly accessible data is essential for a more
