Influence of freight transport purchasing processes on logistical variables related to CO2 emissions: a case study in Sweden

Emissions from freight transport stem from logistical variables such as vehicle utilisation, fuel efficiency, and distance. The purpose is to determine how shippers’ freight transport purchasing processes influence logistical variables. A multiple case study of freight transport purchasing processes was conducted, based on interviews with transport purchasers and providers. Three causes of influence of shippers’ purchasing processes on logistical variables were found: specific requirements, network structure of transport providers, and scope of contract. Specifications by purchasers, especially time requirements, influence several logistical variables (‘mode used’, ‘length of haul’, ‘load factor’, ‘empty running’, and ‘fuel efficiency’). This paper clarifies the implications of transport purchasing on CO2 emissions in terms of logistical variables, which are understood in transportation research and practice. It describes the effects of shippers’ requirements on transport providers’ execution of transport. The results provide a foundation for shippers to discuss their influence on logistical variables with transport providers.
