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-2cf660d6b3a32f7c quantitative
From May 2021 to August 2022 Google's first electric Street View car, fitted with Aclima's mobile sensing platform, drove Dublin City's streets for Dublin City Council's Smart Dublin programme

Claim 7 clm-540623f6c661cdde quantitative

Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Quoted from the officer: large development sites show spots of elevated PM2.5 along their roads, and the council with its planning colleagues is putting very strict restrictions on construction-site housekeeping.
Caveat
The officer's statement does not say how many sites were affected or whether the restrictions were new.

  1. The Irish Times, 14 February 2023 (media)
Claim 9 clm-5f08bf1686694d8a quantitative
A peer-reviewed UCD and DCU analysis of one year of the drives found NO2 above the WHO 24-hour guideline on 49.4% of the sampling time
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The study covers 6 May 2021 to 6 May 2022 and reports NO2 exceeding the WHO 24-hour guideline in 49.4% of the one-year sampling time.
Caveat
The drives ran on weekdays in daytime, so the share describes daytime weekday conditions, not the full day.

What the mapping says
The study maps NO2 and PM2.5 hotspots and states that highly polluted days account for 56.3% of total NO2, highlighting local traffic as the dominant contributor to short-term NO2; the named streets come from the university's hotspot analysis.

No traffic measure has been documented as following from the maps
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
None of the listed sources names a traffic or road measure taken on the basis of the Air View maps; the plan assigns the project to citizen engagement and the launch statements speak of informing future policy.
Caveat
This is an absence in the sources consulted, not proof that the data was never used.

Published field

Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The plan lists Airview under Measure 12, Citizen Engagement; the construction-site restrictions are the only action tied to the findings in the launch coverage.
Caveat
The campaign began before the plan was finalised; the plan adopted it rather than commissioning it from scratch.

Report on the launch. The council's principal environmental health officer Martin Fitzpatrick says the car went down every street at least six times, a median of 14 times; that the existing network with the EPA monitors at 26 locations and the project complements rather than replaces it; that the maps first show NO2 and PM2.5; and that elevated PM2.5 along roads by large development sites has led the council, with the planning department, to put 'very strict restrictions' on construction-site housekeeping. Notes elevated NO2 on the Liffey quays, Doyle's Corner in Phibsborough and busy approach roads.
