This research provides an overview of the process and results of the development and implementation of the Port Activity Application. The aim of the application is to improve the coordination and information exchange mechanisms between the existing systems of ports and ships during piloting ordering process to ensure their effective interoperability, giving a better understanding of the impact of digitalization on the sustainability of seaports and maritime transport. To implement this concept, a system of step-by-step actions was developed, including determining the current situation, developing a business model and business logic for implementing an appropriate information and communication technology (ICT) solution, analysing the local government structure, analysing intermodal information exchange between stakeholders, developing and testing a new ICT tool. The ports of Rauma, Finland, and Gävle, Sweden, were used as pilot ports. As a result of the study, the main bottlenecks in the process of information exchange in ordering pilotage were identified. An improved business model and business logic, that allows the rational use of resources and reduces CO₂ emission and the pressure on the environment, was developed. The testbed was conducted in an environment of real port operations. Currently, the open access source code is available for use for maritime cluster actors.

Purpose - Coastal and marine tourism, consolidated by national and local governments' aspirations to improve the vitality of the economy by developing the tourism sector, is considered one of the key contributors to the EU's blue growth. The challenge remains how to do this without compromising the sensitive nature and needs of local communities for environmental, social, economic and cultural sustainability. The aim of this research is to understand how to enhance sustainable coastal and marine tourism from the perspectives of green skills, value co-creation and multi-stakeholder engagement. Methodology - The applied methodology is mixed methods, including qualitative and quantitative approaches. Findings - The findings highlight the need to support stakeholders' capabilities, such as green skills, to be able to cooperate and engage in co-creating sustainable tourism with other stakeholders. Our case studies highlight the need for skills development at different levels to empower stakeholders to change their behaviour, engage in co-creation and acknowledge new technologies that support the transformation to sustainable tourism. Implications - Our study highlights the value of co-creation as a theoretical perspective in studying sustainable tourism, confirms the previous theoretical claim of a holistic, sustainable development view in coastal tourism and provides insights for its management
