Kraków's new SCT regulations, which took effect on January 1, prohibit vehicles that do not meet specific emission standards from entering almost all residential areas. For petrol cars, at least a Euro 4 standard (2005 or newer) is required, while diesel vehicles must adhere to Euro 6 (2014 or newer). Residents who owned a vehicle before June 26, 2025, are exempt from this restriction if they register their vehicle with the verification system. Non-residents will have a transitional period of three years, until the end of 2028, during which they can enter the zone after paying a fee, currently set at 2.50 zł per hour or a daily charge of 5 zł, which will rise to 15 zł by 2027.

The adjustments to the SCT regulations stem from growing pressure from residents who are increasingly concerned about air quality in Kraków, a city known for high pollution levels. The modifications reflect a community-driven effort to prioritize environmental health while balancing the needs of car owners. This includes a transition period for non-residents, which provides them with a window to adapt to the new rules while ensuring that residents feel their concerns are being acknowledged.

Furthermore, the pricing of vehicle access will evolve over the years, suggesting a strategic approach to reducing traffic and pollution. Monthly subscriptions will also increase significantly, escalating from 100 zł in 2026 to 500 zł by 2028. Through these instituted changes, Kraków aims to cultivate a sustainable urban environment, improve air quality, and potentially set an example for other cities dealing with similar pollution problems.
