Starting October 1, 2025, and lasting until April 30, 2026, older vehicles will be prohibited from circulating in central Plovdiv. The municipal council adopted this measure as part of an Ordinance establishing low-emission zones across the city to reduce harmful air pollutants. The new regulations define two specific areas: a small ring, called the Center, and a larger surrounding area, the Wide Center. Within these zones, vehicles classified under environmental groups 1, 2, and 3 will not be allowed to operate during the seven-month period. In addition, the council voted to allocate 300,000 leva (150,000 euros) in the 2026 municipal budget to prepare a phytosanitary assessment of the city’s tree vegetation across all districts.
