Background: The selection of transport operators has become a complex decision making process with multi-criteria aspects. Deciding on which transport operator to use depends on various service offerings that can be different for each company. Retailers such as those from France, the Netherlands, Sweden and UK look to improve logistical performance in areas such as lead time, flexibility and reliability, and improve customer relations.

Sub question1: Are the retailers willing to use green service offerings and why? Sub question2: Which of the green service offerings are important for French, Dutch, Swedish and UK retailers in their selection of transport operators? Purpose: The purpose of this paper is to find out what the most important service offerings are for French, Dutch, Swedish and UK retailers in their selection of transport operators. It also aims to determine if French, Dutch, Swedish and UK retailers are willing to use green service offerings and explain why. Finally, it will attempt to identify which of the green service offerings are important for French, Dutch, Swedish and UK retailers in their selection of transport operators.
