Tbilisi is ranked by the World Health Organisation (WHO), as being among the most polluted capitals in Europe. The city’s poor air quality is primarily driven by traffic-related emissions, further exacerbated by weak emission regulations and rapid urban development. Up to 90% of the city’s air pollution originates from the transport sector, resulting in high concentrations of nitrogen dioxide (NO₂) that exceed WHO-recommended limits several times over.

Rustavi, a city of around 130,000 residents, has long been associated with heavy industry, which has led to significant air pollution. Since the second half of the 20th century, dozens of large and medium-sized enterprises have been established here — steel mills, cement plants, chemical factories, and facilities producing fertilizers and manganese compounds.
