Low Carbon Shipping is a multi-chapter book that maps the transition of maritime transport toward decarbonisation. It begins with port-side infrastructure and bunkering systems (LNG, hydrogen, ammonia, methanol), shore power, ports as energy hubs, CO₂ transport infrastructure, and smart-port sustainability. It then covers life-cycle assessment (LCA) methods for maritime fuels (well-to-wake analysis, uncertainty, digital-twin-enabled real-time LCA, and comparative environmental performance). A dedicated chapter addresses digital technologies and smart shipping, including digital twins, IoT monitoring, predictive analytics/AI, real-time emission monitoring, MASS/autonomy, blockchain, and the evolution toward sixth-generation ports. The book also provides regional perspectives and case studies (US, EU, China, Mediterranean/Middle East, developing regions, governance and standards coordination), and closes with future pathways, including technology and cost benchmarks, investment needs, barriers, timelines, policy actions, and decarbonisation roadmaps.
