From December 1, 2023, Sofia will implement a new policy restricting access to its city center for highly polluting vehicles. This initiative, part of the city’s environmental strategy, targets vehicles in the lowest ecological category, aiming to improve air quality during winter. This approach, already adopted in over 300 cities globally, is designed to reduce emissions in key areas while offering alternate routes to maintain traffic flow. The plan includes central city zones, effectively discouraging the use of personal cars between the city’s western and eastern districts. Vehicle eligibility for entering these low-emission zones can be checked via eco-stickers on car windshields, which indicate the vehicle’s environmental classification.
More information about EURO-1 vehicles and low-emission zones can be obtained from the Sofia Municipality web page.
