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-19ed63e21228b5b1 quantitative

Airparif recorded a large regional NO2 fall over 2012–2022 but attributes it mainly to fleet renewal and lower traffic

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Airparif's 2024 evaluation reports NO2 exposure down about 40% over 2012–2022, driven mainly by fleet renewal, with the ZFE one contributing factor.
Caveat: The attribution comes from Airparif's modelling, not a controlled experiment.

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.
