Madrid Central / Madrid 360 Low-Emission Zone

Revision 2026-08-26-claim-mapping · effective 2026-07-25

Current revision. This is the snapshot used by the live entity page.

unreviewed

Added a seven-claim evidence mapping and a sourced lesson; replaced a wholly qualitative impact with the measured NO2 record (22 of 24 stations down in 2019 against the 2010-2018 mean, Plaza del Carmen down 10 micrograms or 22 per cent and under the legal limit for the first time, 10 per cent citywide) and corrected the peer-reviewed source's journal, which is Transportation Research Part D, not Part A.

Claim 6 clm-b7a2e76db10b84ee quantitative
A peer-reviewed study of the same station attributes a significant NO2 reduction to the zone and finds smaller but still significant reductions at stations just outside it, which it reads as evidence that the pollution was not displaced outwards
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The paper identifies the effect of the low-emission zone on NO2 at Plaza del Carmen and reports significant though smaller reductions at nearby stations, which it interprets as a positive spillover rather than a transfer of pollution.
Caveat
Elsevier blocks automated retrieval of the full text; the findings are taken from the published abstract.

each annulment was about how the rules were adopted, not about whether they worked

  • 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.
