To ensure environmentally sustainable logistics, organizations need to have anenvironmentally sustainable logistics performance management (ESLPM) process. In line withsupply chain management (SCM) literature, there is a desire towards integrating processes withsupply chain partners to increase performance. The purpose of this paper is to propose a frameworkfor ESLPM process integration and to illustrate this framework in practice between buyers andthird-party logistics (3PLs) providers. The method used is multiple case studies of three dyads of3PLs and buyers from the public and private sector. Data were collected through 10 semi-structuredinterviews. Our major result is a proposed framework with criteria for the degree of ESLPM processintegration between buyers and 3PLs. It includes six activities: Selecting environmentally sustainablelogistics performance (ESLP) variables, defining ESLP metrics, setting ESLP targets, measuring ESLPmetrics, ESLPM feedback, and analyzing ESLP outcomes and processes. It considers suggestedoperationalization of each activity and the corresponding degree of integration. The framework canprovide guidelines for practitioners in identifying current degree of process integration. It may alsosupport decisions regarding actions needed to advance to a higher degree. This framework is the first toaddress logistics performance management process integration including environmental sustainability
