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-618cee7db5f619eb quantitative
Oslo has tolled entry since 1990, but only from 1 October 2017 did pricing become time- and emission-differentiated: rush-hour and diesel cost more, electric cars far less
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Store norske leksikon dates Oslo's toll ring to 1990. Dagbladet states that on 1 October the previous year time- and environment-differentiated rates were introduced, so that a rush-hour crossing then cost 54 kroner for petrol cars and 59 for diesel against 44 and 49 outside the rush, where previously it cost 34 kroner for all cars around the clock. NRK covered the same reform.

Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The Climate Agency's appendix: in June 2019 new toll stations and a new tariff system with more toll cordons were introduced in Oslo and the former Akershus. Fjellinjen's tariff page lists the three rings as Bygrensen, Osloringen and Indre ring.

Fjellinjen — 60% owned by Oslo, 40% by Akershus county — now runs 83 stations across three rings

Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Fjellinjen's investor relations page: 'Fjellinjen is owned by the Oslo municipality (60%) and Akershus county (40%).' Its tariff page: 83 toll stations in Greater Oslo on three different toll rings. Store norske leksikon gives the same 83 across three rings.

Claim 4 clm-dd575139847bf9d9 quantitative
Fjellinjen's economy director told Dagbladet that in the days before Easter 2018, half a year after the reform, crossings were down 4.5% on the same period in 2017 — and said himself that the raw March-on-March figure of 13.8% is mostly an Easter-calendar artefact
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Dagbladet quotes Fjellinjen's economy director Magne Liestøl Larsen: total March traffic was down 13.8 per cent against March 2017, but much of the decline is because Easter fell in March this year and April last year; looking at the days before Easter, traffic was down 4.5 per cent.
Caveat
A self-reported figure relayed by the press, not an independent evaluation; and the October 2017 reform combined time and emission differentiation with an overall rate increase, so no part of the change can be attributed to differentiation alone.

  1. Dagbladet — traffic fell 4.5% in March (press)
Claim 5 clm-ebd563f848f7e96b quantitative
in the first three months after the new rates, crossings in the half hour from 06.00, just before the rush window opens, were up 8.2% year on year; by March 2018 that increase was 1.9%
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Dagbladet: compared with March the previous year the traffic increase in the half hour between 6 and 6.30, before the rush period, was only 1.9 per cent, whereas in the first three months after the new tariffs were introduced that increase had been 8.2 per cent over the same period of the morning.

  1. Dagbladet — traffic fell 4.5% in March (press)
Claim 6 clm-c88598ad1a5f5479 descriptive
the Climate Agency writes that almost the entire effect of today's toll rates already sits in the reference trajectory, so its table of emission reductions counts only the later rate changes
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Klimaetaten in the 2023 climate budget: only the additional effect beyond the expected emission level in the reference trajectory is shown, and almost the whole effect of today's toll rates lies in that trajectory; the table therefore presents only the effect of the rate changes in the new supplementary agreement to Oslopakke 3 approved by the city council on 22 June 2022.

The climate budget appendix, citing Urbanet Analyse (2017) on the distributional effects of the new toll cordons: men pay tolls more than women because they drive more; households of several people are affected more than single people; and those with middle or high incomes are affected more than those with low incomes.

  • 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.
