Harsh winters, aging infrastructure, and the demand for modern amenities are major factors contributing to deteriorating air quality in Bishkek. The city meets its winter heating energy needs through coal combustion at central plant, heat-only boilers, situ equipment, while diesel petrol fuel transportation. Additional pollution sources include 30 km2 of industrial area, 16 large open brick kilns, a vehicle fleet with an average age more than 10 years, 7.5 quarries, landfill. annual PM2.5 emission load airshed is approximately 5500 tons, resulting concentration 48 μg/m3. Wintertime daily averages range from 200 300 meteorological modeling was conducted using WRF–CAMx system evaluate source contributions support scenario analysis. Proposed emissions management policies shifting clean fuels like gas electricity heating, restricting secondhand imports promoting newer standard vehicles, enhancing public transport buses, doubling waste collection efficiency, improving landfill management, encouraging greening, maintaining road infrastructure control dust emissions. Implementing these measures expected reduce levels by 50–70% mid- long-term. A comprehensive plan Bishkek should expand ambient monitoring network reference-grade low-cost sensors track progress enhance awareness.
