Environmental Impact of Transport

Measuring the environmental impact of transport in Flanders

The MITRANS is a single aggregate indicator which aims to measure the overall effect on the environment of transport (all modes) and its infrastructure. The indicator was constructed for the Flemish government – LNE within the framework of “Vlaanderen in actie: Pact 2020: een nieuw toekomstpact voor Vlaanderen 2020”.

The indicator takes into account five main effects and 11 sub indicators and is calculated for the period 2000-2009. The five main effects are: nuisance, biodiversity & habitat, impact of air pollution, climate change and use of materials. The calculation showed that the overall effect on the environment decreased over the time. This general trend follows the overall decline of the sub indicators for nuisance, impact of air pollution, climate change and the use of material between 2000 and 2009.

The figure below shows the general trend of the MITRANS.
