src-07c7e289c6c35e74The city road authority's page for the zone: 37 km², about 7% of Warsaw, most of Śródmieście and parts of the neighbouring districts, in force since 1 July 2024; the 2026 stage rules; residents registered in Warsaw and paying tax there exempt until the end of 2027; the online register check and sticker application.
src-2d64ee60f569b3f1Report of the council vote of 7 December 2023 (37 for, 16 against, 2 abstentions), the reduced boundary, the residents' exemption to January 2028, the indefinite exemption for people aged 70 by the end of 2023, and the fine under Article 96c of the Code of Petty Offences.
src-2adec8a1c26b9f04Launch-day check by the municipal police and ZDM near ul. Tatarska: a camera showed permitted cars in green and banned ones in red; ten drivers were cautioned. Describes the zone as Poland's first.
src-23c1f3909a21a34eMunicipal police figures relayed from TVN24: 64,430 vehicles registered entering the zone in its first half-year, 740 not entitled, no offence under Article 96c; a second camera added at the start of 2025.
src-e0cf441cfe53ea39One-year review: the deputy commander of the municipal police says non-compliant cars were under 0.6% of entries recorded and no vehicle had passed the four-day limit; enforcement by a few patrols with four cameras; Clean Cities Polska argues for a move from penal to administrative enforcement.
src-38e507fa5d90c507Reports the first fine ever issued in the zone, more than a year after launch, and that the zone has no barriers and no permanent checkpoints.
src-5a3f17df9cb91b7eHow a check works: a patrol places a plate-reading camera in front of its car, the system flags non-compliant vehicles from the Central Vehicle Register, officers stop and verify; four entries a year allowed, the fifth punishable, fine up to 500 zł; a planned ANPR network due from April 2026.
src-903d3ee5808e7db1City spokesperson on the design: no charges, age limits tightened every two years on a schedule written out to 2032; indefinite exemption for people aged 70 by 31 December 2023; municipal police figures to 13 February 2026.
src-e5e282ea4cd5fe0bMunicipal police figures for 1 January to 20 February 2026 (87 violations, 58 proceedings, 16 fines, 13 educational measures); four mobile cameras matching plates against the list of entitled vehicles; ZDM's plan for 15 traffic-management camera devices, run by Yunex, to gather statistics on the zone, not to check drivers.
src-8db4f7c6f4a231acThe 2026 entry rules; first fine in mid-November 2025; four mobile cameras checking the Central Vehicle Register; explains that entering is a petty offence, so the offender must be identified and a plate reading alone cannot produce a fine; ZDM's camera analysis is not for penalties.
src-3063ff423e1360cbPreliminary data from the city's Office of Air Protection and Climate Policy, published by Clean Cities Polska: average annual NO2 down 18% inside the zone since its introduction against 5% outside; the group says this does not prove the zone alone caused the larger decline.
src-836967746da40ed6Two-year review: the same 18% inside versus about 5% outside NO2 comparison for 2023–2025, here attributed to Warszawski Alarm Smogowy; argues the zone so far bites only on visitors, which is why it has caused less anger than Kraków's.
src-9881e5132d08c1c0Peer-reviewed first-year evaluation comparing the zone with the rest of Warsaw in March 2024, October 2024 and March 2025: small retiming of car traffic, no large-scale displacement, no consistent air-quality difference in 2024 and higher particulate and NO2 concentrations inside the zone by March 2025 in the observation-level analysis, with limits from meteorology and monitor coverage.
