What is causing poor air quality in Sarajevo?
The primary causes of poor air quality in Sarajevo include:
- Home heating: An estimated between 30,000 and 40,000 households rely on damp wood, biomass, and inefficiently-burning stoves. Home heating sources emit excessive amounts of PM2.5 (1).
- Geography: Sarajevo lies in a valley surrounded by mountains. This helps trap pollutants and reduce airflow in fall and winter months.
- Industry and vehicle emissions: Outdated vehicles, factories, and coal-burning power plants are the primary sources of regional nitrogen oxides (NOx) and sulfur dioxide (SO₂) emissions (2).
- Weather: Temperature inversions and cold temperatures in autumn and winter worsen pollutant accumulation.
