Purpose: The research in the article was conducted to diagnose the state of environmental protection in the West Pomeranian region, that is, to get an answer to the question in which districts the state of environmental protection was at the best level in which the situation was worse. Design/methodology/approach: The article classifies 21 counties of the West Pomeranian region in terms of the state of environmental protection in 2020. The counties were divided based on the taxonomic development measure as a tool for classifying socio-economic objects. Findings: The study showed that the best state of environmental protection was characterized by the districts of Sławieński, Choszczeński, Police, and the city of Koszalin. The worst state of environmental protection was characterized by the districts of Pyrzyce, Kamienski, and the city of Szczecin. Research limitations/implications: A taxonomic study conducted based on a set of variables that do not contain the most relevant characteristics (due to lack of statistical data) of the studied phenomenon may lead to an erroneous assessment of reality is the most significant limitation of this article. Practical implications: The presented study can be used at the regional level to assess environmental problems and determine corrective and counteracting actions to the current situation. Social implications: The results of the study make it possible to revise the actions of environmental policy realized in the West Pomeranian Voivodeship. Originality/value: This study is an independent and comprehensive analysis of the state of environmental protection in the West Pomeranian province.

Purpose: The aim of this article is to present selected research results in the field of optimization of energy cogeneration processes of heating systems based on biogas sources, in terms of the possibility of obtaining ecological and energy benefits in the municipal area. Design/methodology/approach: The considerations are a case study, including an analysis of the choice of the optimal variant of agricultural biogas construction in the Łobez Municipality in the Zachodniopomorskie Voivodeship from the point of view of both the substrate used in biogas and the proposed technological solutions. The subject matter focuses on comparing the estimated ecological effect of biogas with different powers and choosing the optimal model solution. The research process used secondary and statistical data and the selected comparative method to calculate the carbon dioxide emission reduction factor. Findings: The authors indicate which technology of obtaining energy should be dominant in the field of optimization of energy cogeneration processes of heating systems in Poland in areas dominated by agricultural economy. Research limitations/implications: The presented research concerns the assessment of one of the parameters (substrate used in biogas) affecting the optimization of biogas production. Future research in this area should focus on the assessment of other factors determining the validity of the discussed solutions in relation to the adopted state policy in the field of development of renewable energy sources and agricultural economy. Practical implications: The results of the research are the first approach to indicate the government and regional administration the type of energy that may form the basis of the future strategy of changes in the field of energy cogeneration of heating systems in municipal and agricultural areas in Poland. Social implications: The description of the agricultural biogas model, which served as an example, can be helpful in the process of identifying benefits not only for the environment but also as an element stimulating economic and social development at the local and regional level. Originality/value: An experimental research approach may be helpful in understanding the essence of optimization of energy congregation processes of heating systems based on biogas sources in selected areas of Poland.

In recent years, the development of renewable energy sources has become one of the key demands in the European Union's policy. In Poland, the idea emerged that the energy potential of domestic agriculture may be an opportunity for broader use of the available agricultural biomass. Given that agricultural biogas has long been seen as one of the most promising directions for energy transition, the goal of the article was to assess the potential of the agricultural biogas market in Poland. The research methodology was based on statistical measures related to analysing the structure and changes over time in individual years. The structure analysis was carried out for selected Polish provinces, for which empirical distributions were built and selected descriptive parameters were calculated. A similar study was made in relation to selected EU countries. In addition, according to the National Action Plan for Renewable Energy, at least one agricultural biogas plant should be established in each Polish municipality. On this basis, the article assesses the ecological effect of the project on agricultural biogas in Marcinkowice, in the Zachodniopomorskie Voivodeship. The presented simulations allowed us to conclude that an agricultural biogas plant can be an ecological potential in the form of reducing the consumption of fossil fuels by reducing emissions of pollutants and greenhouse gases into the atmosphere while reducing fossil fuel consumption. It was important for the practice to confirm that investing in renewable energy sources, including the use of biogas, is part of the goals and directions of development related to the sustainable management of environmental resources and the development of renewable energy sources.

W ostatnich latach jednym z kluczowych postulatów w polityce Unii Europejskiej stał się rozwój odnawialnych źródeł energii. W Polsce pojawiła się idea, że potencjał energetyczny krajowego rolnictwa może stanowić szansę na szersze wykorzystanie dostępnej biomasy rolniczej. Biorąc pod uwagę fakt, że biogaz rolniczy od dawna postrzegany jest jako jeden z najbardziej obiecujących kierunków transformacji energetycznej, celem artykułu była ocena potencjału rynku biogazu rolniczego w Polsce. Metodologia badań została oparta na miarach statystycznych związanych z analizą struktury i zmian w czasie w poszczególnych latach. Analizę struktury przeprowadzono dla wybranych województw Polski, dla których zbudowano rozkłady empiryczne i obliczono wybrane parametry opisowe. Podobnej analizy dokonano w stosunku do wybranych krajów unijnych. Ponadto zgodnie z Krajowym Planem Działań w zakresie energii ze źródeł odnawialnych w każdej polskiej gminie powinna powstać co najmniej jedna biogazownia rolnicza. Na tej podstawie w artykule dokonano oceny efektu ekologicznego projektu biogazowi rolniczej w miejscowości Marcinkowice, w województwie zachodniopomorskim. Przedstawione symulacje pozwoliły na stwierdzenie, że biogazownia rolnicza może stanowić potencjał ekologiczny w postaci ograniczenia zużycia paliw kopalnych poprzez zmniejszenie emisji zanieczyszczeń i gazów cieplarnianych do atmosfery, przy jednoczesnym ograniczeniu zużycia paliw kopalnych. Istotnym dla praktyki było potwierdzenie, że inwestowanie w zakresie odnawialnych źródeł energii, w tym wykorzystanie biogazu, wpisuje się w cele i kierunki rozwoju związane ze zrównoważonym gospodarowaniem zasobami środowiska i rozwojem odnawialnych źródeł energii.

Introduction/background: Rational and effective management of public real estate is necessary for the proper functioning of this entity, as well as for the implementation of public tasks. Moreover, real estate stock is an important source of income. In order to find this out, it is necessary to analyze the state of a commune’s real estate resources, focused on the implementation of specific goals such as: public investments and implementation of technical infrastructure devices. Aim of the paper: The aim of this publication was to assess the role and significance of the share of income from real estate in the total income of the Szczecin City Commune; therefore, the research focused mainly on this income group. To fully illustrate the essence of the share of income from real estate, other sources of income of the audited entity are presented. Materials and methods: A study of the measurement and evaluation of the phenomenon of changes over time was carried out on the basis of an analysis of the income dynamics of the Commune of Szczecin, with particular emphasis on the sources of income, as well as being broken down into budget classification sections. Moreover, in order to determine the changes taking place in the structure and level of the studied phenomenon over time, the dynamics indicators with a constant basis were calculated. Results and conclusions: The conducted research has shown that real estate resources are an important source of income for the commune, and the most important of them is the real estate tax. The budget revenues from this source amounted on average to over PLN 240 million. In the years 2017-2019, the budgetary income of the commune had a growing tendency, and its value was, respectively: PLN 2,157 million, PLN 2,289 million and PLN 2,639 million. The structure of the commune’s income in the analyzed period shows a stable tendency and did not undergo major changes. The dominant item in the category of current income was the share in the income tax from natural persons and legal persons (share at an average level of approximately 28%).
