COVID-19 has had a serious impact on the development of the global shipping industry, especially since the impact on the cruise tourism industry was unprecedented. This study took cruise ships sailing in China ECA, China Exclusive Economic Zone (EEZ), Yangtze River main line, and Xijiang River main line Chinese waters as an example to analyze the key changes in cruise ship emissions during the pandemic. Automatic identification system (AIS) data, vessel static data, and emission control regional data are used to conduct a comprehensive analysis of cruise ship emissions from multiple perspectives such as a port-to-regional comparison. As such, a vessel emission model (i.e., a bottom-up method) is constructed in this research for predicting China ECA and EEZ cruise ship emissions. Compared with 2019, the cruise activities sailing in China's Emission Control Area (ECA) are mainly at berth, and the emissions of cruise ships have dropped significantly, with SOx emissions reduced by 59.11%. In addition, this study also calculates the carbon emissions of China's regional cruises, supplementing China's cruise carbon pool. The research results suggest that cruise operators may improve fuel efficiency, decrease vessel speed, improve routing and scheduling, and enhance fleet management in order to further mitigate the negative effects of the cruise tourism industry on the marine environment.

The maritime transport sector poses significant air quality concerns, particularly in nearby cities. Ultrafine particles (UFP, diameter < 100 nm) are of particular concern due to their potential health impacts. This study measured particle number concentrations (PNC), size distributions (PNSD), and other pollutants including particulate matter (PM), nitrogen oxides (NO), black carbon (BC), sulfur dioxide (SO) and ozone (O), organic markers and trace elements at a major European harbor and an urban background (UB) location.

This study examines pharmaceutical residues in the seawater of west Spitsbergen fjords, using indicator compounds that represent different types of medications with various therapeutic uses (sulfamethoxazole, trimethoprim, carbamazepine, diclofenac, and caffeine). Over three years (summer 2018-2021), trimethoprim, carbamazepine, diclofenac, and caffeine were detected in the investigated fjords (Hornsund, Adventfjorden, Grønnfjorden, Isfjorden, and Kongsfjorden), with diclofenac and caffeine being the most common. Sulfamethoxazole was below the limit of detection in all samples.

Large passenger ships are characterised as enclosed and crowded indoor spaces with frequent interactions between travellers, providing conditions that facilitate disease transmission. This study aims to provide an indoor ship CO dataset for inferring thermal comfort, ventilation and infectious disease transmission risk evaluation. Indoor air quality (IAQ) monitoring was conducted in nine environments (three cabins, buffet, gym, bar, restaurant, pub and theatre), on board a cruise ship voyaging across the UK and EU, with the study conducted in the framework of the EU HEALTHY SAILING project.

Background: With various infectious disease risks to passenger ship travellers, guidance for infectious disease prevention, mitigation and management (PMM) exists. Emerging infections and emergencies necessitate updated, context-specific guidelines and practices. New evidence for infection PMM must be translated into guidance for governmental authorities and the passenger ship industry.

With the increasing demand for reducing CO2 emissions by the International Maritime Organization (IMO), controlling a ship's energy consumption at the design stage is crucial for proposing a 'greener' design. Some efforts have been made to consider the Energy Efficiency Design Index (EEDI) and the Energy Efficiency Operational Index (EEOI); however, the latter remains highly complex and contentious. In this study, a multistep optimization analysis method was developed to integrate EEDI and EEOI evaluations during the design stage to meet low emission requirements.
