This study investigates the inclusion of environmental performance in transport contracts, and studies if differences in inclusion can be explained by intra-organizational involvement. Findings from a survey study targeting logistics service providers and shippers suggest that those who include environmental performance in contracts, not necessarily consider how to measure the environmental performance and how to handle non-compliance. A higher degree of intra-organizational involvement is related to larger inclusion of environmental performance in contracts. Findings also indicate that transportation managers play a more important role for inclusion of environmental performance in contracts, as compared to top management and environmental managers.
