The article addresses the issues related to sustainable inland waterway transport in the context of stimulating transformations towards a green economy. The considerations focused on the second-largest river in Poland – the Oder. The clear economic needs and benefits arising from the river’s regulation and the restoration of its transport capabilities were juxtaposed with the results of a study regarding the perception of these changes by the public opinion. To clarify, these were the residents of the Oder River Basin, thus people in the immediate impact area of the river.

The role of inland navigation in the global logistics system is gaining significance. This process is stimulated by policies implemented by major economies and international organizations such as the European Union. The objective is to achieve sustainability in transportation by exploring alternatives to conventional infrastructure. These initiatives also extend to tourism and recreation associated with inland navigation. This article presents the results of an analysis related to the location of a tourist river port, considering optimized benefits and developmental opportunities. An interesting location meeting these criteria, as well as possessing scenic, cultural, ecological, and environmental values, is Gorzów Wielkopolski. In the second part of the article, the authors propose a concept for a sustainable energy system that meets the requirements of port operations and customer demands in an era of rapidly advancing technology and increased emphasis on environmental protection.

A multidimensional analysis of one of main macroeconomic indicators, specifically, unemployment, in the United States was conducted and presented in the article. The research covered several groups of dependent variables, such as: the number of unemployed people in total in the United States monthly, along with unemployment rates, CPI indices, and unemployment in respective US states. The evaluation of the conducted research is that from January 2020 to October 2023 there had been a visible decrease in unemployment rates, and their level is similar to the values recorded from January 2018 to January 2020, which clearly proves that the crisis caused by the COVID-19 pandemic has been averted. The analysis method was used in the study, i.e. distribution of variables into prime factors and comparison dynamically in order to detect the regularities occurring in them.
