The growth of regional ports (in sub-national context) and their host regions is conditional upon one another. A regional port requires a vision for growing its business as well as its region. To achieve this goal, it is essential for regional ports to initiate effective strategies. This paper explores the pertinent factors and strategic initiatives for effective involvement of Australian regional ports in regional development through a questionnaire survey to Australian regional port stakeholders. Using exploratory and confirmatory factor analyses, this study suggests that Australian regional ports undertake multiple strategies when involved in regional development, including collaboration to create supply chain efficiency, collaboration with regional organisations for regional growth, playing a proactive role in the regional innovation system, and being pro-active for port's environmental and social responsibility.

Reducing CO₂ emissions from global shipping remains a critical challenge in the pursuit of sustainable international trade. Though the technical and operational (T/O) measures and alternative fuel (AF) solutions have shown promise, the global maritime sector continues to face strategic and structural hurdles. This thematic narrative review revisits the fundamentals and explores the roles of T/O measures and Alternative fuel options in reducing CO₂ emissions in international shipping, with a focus on the maritime energy transition. The study reveals that maximizing the benefits of T/O measures, alongside establishing a balanced energy transition matrix encompassing clean energy sources, can foster an environment conducive to future sustainability performance and substantial CO₂ emission reductions. More specifically, combining operational efficiency improvements with scalable, future-focused, infrastructure-ready alternative fuels can yield significant emission reductions. The paper also introduces a conceptual model to guide the maritime energy transition, outlining a phased pathway that leverages innovation, policy, and system-level design. These insights contribute to shaping a resilient roadmap for decarbonizing international shipping by enhancing the sector’s sustainability performance.
