Purpose: The interface between Logistics Service Providers (LSPs) and shippers is an area that hasreceived little attention in previous research and even less has been done when environmentalissues are added to this interface. Nonetheless, the perception among researchers and the industryis that in many instances, supply and demand in this green interface does not coincide. The purpose of this paper is therefore to identify the matches and gaps between LSPs’ green supplyand the shippers’ green demand. Design/methodology/approach: This paper is based on a web-based survey sent out to Swedish LSPs and shippers. A gapanalysis based on mean values and confidence intervals was conducted. Findings: Findings indicate that the LSPs overachieve when it comes to green categories and also that theyare aware of this situation. Shippers, on the other hand, are interestingly not aware of this andthey seem satisfied with what they perceive is offered by LSPs. Research limitations/implications: Contrary to previous research, this study specifies matches and gaps in the green LSP-shipperinterface. As the survey covers actors on the Swedish market, future research would benefit fromsimilar analyses from other countries. Practical implications: The findings are of use for LSPs’ understanding of shippers’ environmental demand, and therebyenable them to adapt better to market demand. Similarly, shippers can use the findings tounderstand green supply and possibly change their demands accordingly. Originality/value: This paper adds to the knowledge of the green LSP-shipper interface. Furthermore, it uses gapanalysis, which appears to be something not previously done within environmental logisticsresearch.
