Selvom tallene er usikre som følge af problemer med metodik ogdata, anslås den nuværende inddækning af infrastruktur- ogmiljøomkostninger kun til ca. 30 % for vejtransport og 39 % forjernbanetransport.
Although the figures are uncertain because ofmethodological and data problems, the level ofinternalisation of infrastructure and environmental costs isestimated to be only about 30 % for road and 39 % for rail.This means that transport revenues (via relevant taxes andcharges) still do not cover all external costs.
