Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-4f5258a3706b9659 quantitative
Milan's Area C uses 43 automatic number-plate recognition gates to charge and restrict polluting vehicles entering the 8.2 km² historic centre, running since January 2012
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The city's own page describes Area C as 'a limited traffic zone in central Milan that requires a fee to enter. Entry is regulated by electronic gates that detect vehicle license plates.' The gate count, the zone area and the January 2012 start are the standing record in the reference account and the case study.
Caveat
No claim-specific caveat recorded

  2. Wikipedia (reference)
  3. C40 Cities — case study (independent case study)
Claim 2 clm-9658ed7ebe918b2b descriptive
Toll revenue funds bike lanes, pedestrian streets and the BikeMi bike-share network
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The C40 case study describes the hypothecation of Area C revenue to sustainable mobility in the city, including cycling infrastructure and the bike-share network.
Caveat
The case study is bot-walled to automated reading; the hypothecation is its standing account of the scheme and no locator string is recorded.

  1. C40 Cities — case study (independent case study)
Claim 3 clm-3a3894409b011f7b quantitative
city data show in-zone congestion down about 28% and CO2 emissions down about 35%
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The C40 case study reports the city's own measured reductions for the zone.
Caveat
Figures the city measured and C40 republished; the page blocks automated reading, so no locator string is recorded.

  1. C40 Cities — case study (independent case study)
Claim 4 clm-4159938a1749c6d0 quantitative
a 28% drop in in-zone congestion, a 49% drop in the most polluting vehicles (-2,400/day, cleaner-vehicle share up from 9.6% to 16.6%), and roughly 35% lower CO2 and 18% lower NOx since introduction
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The full set of figures as published in the C40 case study of Area C, all of them the city's own measurements for the charged zone.
Caveat
All of these are the city's own figures, republished by C40. The page blocks automated reading, so no locator string is recorded, and no independent evaluation was found for this entry.

Claim 5 clm-8c8cf183dfdc8541 quantitative
Milan publishes a calendar of vehicle-class bans running to 2030

Known limits of this passport
  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
  • A missing archive, publication date or content hash is shown as null rather than inferred.
  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
