What is causing poor air quality in Sarajevo?
The primary causes of poor air quality in Sarajevo include:
- Use of solid fuels for heating: Between 30,000 and 40,000 households rely on damp wood and low-quality stoves, which produce large quantities of fine particulate matter (PM2.5) (3).
- Geographical factors: Sarajevo’s valley location surrounded by mountains traps smog and limits air circulation, particularly in colder months.
- Traffic and industrial emissions: Older vehicles and local industries contribute significantly to nitrogen oxides (NOx) and sulfur dioxide (SO2) emissions.
- Climate conditions: Low temperatures and temperature inversions during autumn and winter exacerbate the buildup of pollutants.
