Analysing sustainability change management in government owned companies: experiences from European ports

Purpose Government-owned companies (GOCs), such as ports, have engaged in efforts to become more sustainable. Most of such efforts have been technological and policy ones and mainly focusing on the environment, with limited research on organisational change management. This paper aims to provide insights into how ports have been addressing sustainability change forces and pressures. Design/methodology/approach Twelve semi-structured interviews were conducted with top-level directors and sustainability managers, representing ports across Europe’s maritime regions and a range of port types and sizes. The interviews were analysed using grounded theory’s constant comparative analysis. Findings The findings highlighted that the ports’ success in their process to become more sustainable depends on how they take advantage of the thrust forces and reduce the drag ones. The findings serve to develop the “ports’ sustainability change management framework”, with five stages: reactive, proactive, transactive, interactive, and sustainable port. Practical implications Ports, and other GOCs, should capitalise on their private–public nature in their contribution to making societies more sustainable by adopting a holistic perspective and interactive changes. Originality/value This paper provides a dynamic perspective on corporate sustainability efforts, particularly on GOCs, through organisational change management complementing technocentric and managerial approaches.
