This environmental product declaration (EPD) describes, from a lifecycle perspective, the total environmental impact of track foundations on the Bothnia Line. Railway track foundations form what may be called the "ordinary" railway (i.e. stretches of rail that do not run across bridges or through tunnels). The EPD covers track foundations substructure only. Track, power, signalling and telecom systems on the track foundations are not included.
The aim of this EPD is that it should provide experts and scientists (in the construction and infrastructure sectors) with objective and reliable information on the environmental impact of constructing, operating and maintaining railway track foundations.
