How this atlas is made · What “last verified” means · What “source-checked” means · The full record behind this page

Italy's largest low-emission zone covers about 72% of Milan and charges nothing; entry is by emissions class, read by some 180+ camera gates. The tightening keeps slipping, with Euro 5 diesel pushed to October 2026.

Launched on 25 February 2019, Area B is Italy's largest low-emission zone, covering about 72% of Milan's territory (128 km²) and roughly 98% of its residents. A network of some 180+ ANPR camera gates, switched on in phases, automatically enforces a progressively tightening ban on the most-polluting vehicles — oldest petrol and diesel classes first, then Euro 4 diesel from October 2019, with Euro 5 diesel cars added since — the city's own calendar lists them among the bans already in force without naming the date, and gives dates only for the tiers still to come. A MoVe-In mileage-monitoring scheme lets drivers of otherwise-banned vehicles keep limited access. Unlike the small central Area C, Area B is a free zone — no charge, only eligibility by emissions class.

Launched on 25 February 2019

snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Urban Access Regulations is a reference database built under the EU Horizon 2020 ReVeAL project (run by Sadler Consultants and partners); its Milan Area B entry note explicitly claims a '25 Feb 2019 start'. But the page's article body is not static HTML — it is a placeholder div (`data-cityname="Milano Area B"`) filled in by client-side JavaScript that this fetch cannot execute, so the actual figure could not be read directly. The operator's own page (comune.milano.it) does not state an exact launch date in its current, redesigned form; its earliest listed 2019 legal acts (Managerial Resolution 54 of 18.02.2019, Resolution 524 of 29.03.2019, DGC 818 of 17.05.2019) are consistent with an early-2019 rollout but none is dated exactly 25 February.
Caveat
This page could not be rendered by an automated fetch (its content loads via JavaScript); the exact date has not been independently confirmed against the source text itself.

Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
POLIS Network's own headline states this verbatim: "Milan launches Area B, Italy's largest Low-Emission Zone". POLIS is the EU cities-and-regions transport network, not the operator, but this is a direct, quotable superlative claim from an independent professional network, not something the entry invented.

Claim 4 clm-5259bf54e18a8f04 quantitative
128 km²
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The entry's own source note for Urban Access Regulations claims '128.29 km²/~72%' — matching this figure closely. As with the launch date, the page's descriptive content loads via client-side JavaScript and could not be read by this fetch, so the figure is not independently confirmed against the rendered text. The operator's current page and POLIS Network's article do not give a km² figure at all.
Caveat
This page could not be rendered by an automated fetch; the square-kilometre figure has not been independently confirmed against the source text itself.

Claim 5 clm-33203b81e25b41d0 quantitative
roughly 98% of its residents
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
POLIS Network states: "Area B covers an area of almost 1.4 million inhabitants, or 97.6% of the city's resident population." The entry rounds 97.6% up to 'roughly 98%'.
Caveat
The source's precise figure is 97.6%, not 98% — "roughly" covers the rounding, but the underlying number is a fraction of a point lower.

Claim 6 clm-ec3209e74fcd330b quantitative
A network of some 180+ ANPR camera gates
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The entry's own source note claims Urban Access Regulations documents 'camera-gate enforcement'. As with the other Urban Access Regulations figures, the page's descriptive content is loaded by client-side JavaScript this fetch could not execute, so the gate count could not be read directly. Neither the operator's current page nor POLIS Network's 2019 article states a specific camera-gate count.
Caveat
This page could not be rendered by an automated fetch; the gate count has not been independently confirmed against the source text itself, and the operator's own current page does not publish a gate total.

Claim 7 clm-e30a3cde78b6e3c2 descriptive
automatically enforces a progressively tightening ban on the most-polluting vehicles
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
POLIS Network: "Progressive bans will follow for other classes of passenger and freight vehicles until 2030, when all diesel vehicles will be banned in Milan." This supports the progressive, tightening structure of the ban. The operator's own calendar page (linked from the Area B page) likewise lists successive ban tiers scheduled out to 2030.
Caveat
Neither source uses the word "automatically" — that the cameras enforce the ban without manual intervention is implied by the camera-gate mechanism described elsewhere in the sources, not asserted in these exact words.

Claim 10 clm-552a8f83563282d3 descriptive
A MoVe-In mileage-monitoring scheme lets drivers of otherwise-banned vehicles keep limited access
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The operator's own Area B page links to the scheme under the label "MoVe-In, alternative to exemptions for Area B", confirming the programme exists and is framed by the operator as a route to continued access. The page does not itself explain the mileage-cap/black-box mechanics (that detail sits on the separate Lombardy region MoVe-In portal, which is not one of this entry's sources).
Caveat
"Alternative to exemptions" is not the same as "for exempted drivers" — MoVe-In is a route to limited access for vehicles that are NOT exempt (i.e. would otherwise be banned), based on an annual mileage cap tracked by an in-car device, not an extra allowance layered on top of an existing exemption.

Claim 11 clm-65f9c85323492ad0 descriptive
Unlike the small central Area C
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
POLIS Network describes Area C as "the more central 'Area C'", confirming its central location relative to Area B.
Caveat
The source confirms Area C is more central, but no listed source quantifies it as "small" — that characterisation rests on the size contrast with Area B's 72%/128 km² coverage rather than a stated figure for Area C itself.

Published field

What the mapping says
The operator's own Area B page states plainly: "No payment is required for admitted vehicles." Access is instead governed by which emissions class of vehicle is allowed at a given time.
