  4. 23. Green Logistics through Modal Shift - exploring the role of the transport capacity contract

    Författare :Fredrik Eng Larsson; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green logistics; modal shift; mode choice; capacity management; supply chain contracting; intermodal transport;

    Sammanfattning : Among policy-makers in Europe the modal shift - a shift från polluting modes of freight transport to less polluting modes - has been a popular suggestion for reducing CO2-emissions of transportation. In particular, intermodal road-rail solutions, where a combination of road and rail transport is utilized to move trailers and containers, have been stressed as an important measure to reach de desired reduction in emissions.
