“Sustainable shipping for a sustainable planet” was the World Maritime theme for 2020. However, the maritime industry is complex; in addition to the shipping, transportation and port services involved, there are myriad support services interacting directly or indirectly to create value in an integrated and coordinated manner to meet the demands of multimodal transportation processes. The regulatory framework governing emissions and reducing air pollution and production of greenhouse gas emissions has been on the agenda of the International Maritime Organization (IMO) for a long time. The IMO role is critical to the development of sustainable shipping. Digitalisation is advancing rapidly in all sectors, and Maritime Informatics will shape the future of shipping. Huge opportunities exist in the connectivity of ships and ports. With an increased role of technology and need for sustainable shipping, the maritime sector will require continuous digital data flows as real-time transport monitoring and management progresses. Maritime transport is currently transformed by “digitalisation” and “decarbonisation”. Great synergy between these two movements will generate greater benefits for many. This chapter captures the essence of sustainable maritime transport and Maritime Informatics and locate synergy with various IMO initiatives towards meeting its sustainability targets.
