CBSmallPorts project will develop energy efficiency and the level of small ports services in the whole Central Baltic area. The objective is to improve energy supply and use; energy to be used efficiently by the boaters and other small port users. Small ports are diversely located, but in CB area they have same issues to solve: short season, competition of people’s time and limited financial and skills resources for the port development. Various small ports have had a lot of activities and investments both on safety and resource efficiency services. However, currently a common platform for information and marketing to boaters is missing. CBSmallPorts will gather the relevant information, investments done in CB area, and all essential resources into one joint network in order to have all the services widely used and utilized for further marketing. Instead of various separate web apps, the project will formulate a common online platform “SmallPorts” combining the information both for boaters, other service users and small ports. Main theme is climate friendly leisure time in small ports having joint aspect: “We are stronger together”. Essential tasks will be defining the energy efficiency of ports, guidance for small port energy efficient investments, marketing strategy, and open online CBSmallPorts platform to combine the data found from different sources and applications. The project will execute investments supporting environmental approach, energy efficiency and green values in marketing. The activities: e.g. workshops, formulating material and utilization of social media, will be implemented in each of the CB area countries. Furthermore, the project activities will involve dissemination in some of the most appreciated fairs of boating in Finland, Sweden and Germany. Each programme country is represented in the project by small ports both as the target of activities, and as the final beneficiary of project outcomes.
