The health sector is one of the keys to sustainable development. Although it is directly related to only one Sustainable Development Goal (Goal 3, “Ensuring a healthy life and promoting well-being at all ages”), the sector itself, which aims to protect health, is paradoxically at the same time the main emitter of environmental pollutants that have a negative impact on health itself. Therefore, sustainability has become a key priority for health sector organizations, and leadership in this area is essential at all levels. Scientific research plays a particular role here, helping to more clearly define the links between environmental sustainability and the health effects of a polluted environment and climate change as well as indicating the direction of actions needed and disseminating good practices that can help accelerate the adoption of efforts towards climate neutrality and sustainable development of health sector organizations. The aim of this article is to present the current state of the art and future research scenarios in the field of green and sustainable healthcare through a literature review by using the Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) method to perform a bibliometric analysis of papers published in 2012–2022. The Web of Science Core Collection (WoSCC) database is used for this purpose. A total of 144 papers are included for analysis, categorized based on eight fields: author(s), title, year of publication, country, journal, scientific category, and number of citations. Based on the results, themes for future research on green leadership in the healthcare sector are identified and recommended.

The growing climate crisis forces the adoption of radical steps to neutralize our impact on the environment, despite the constantly growing demand for energy. Poland, which according to forecasts will not reach the EU target of 15% share of renewable energy sources by 2030, is nevertheless a leader in the EU in terms of the growth dynamics of the photovoltaic market. The aim of this article is to answer the question as to what caused such a huge interest in solar energy. In this article, the authors focus solely on residential installations. The dataset for the analysis was constructed on readily available national data on photovoltaics showing the key characteristics of the country and prosumers. According to this research, the prosumer’s profile shows that home photovoltaics are most interesting for the poorest households in rural municipalities, in regions with the highest unemployment rate, and among citizens of pre-retirement age. The decision to invest in photovoltaics is also influenced by the availability of subsidies and the price level of energy bills. On the other hand, no impact was found on insolation and environmental pollution. The results of the study will allow for a more conscious shaping of energy policy at the EU, national and regional levels.

The economic assessment of CO₂ emissions from fossil fuels is gaining importance in the context of sustainable development. Climate change, driven by excessive greenhouse gas emissions, poses a significant threat to humanity, requiring an integrated approach that considers both environmental and economic factors. The European Union (EU) plays a key role in global efforts to reduce CO₂ emissions and promote sustainability. This study explores economic approaches to analyzing CO₂ emissions in Europe, focusing on trends in fossil fuel use and their economic drivers. The research highlights the connection between economic activity, energy consumption, and emissions, contributing to a better understanding of climate change mitigation strategies. The findings emphasize the strong influence of demographic factors on carbon emissions, stressing the need for targeted policies to address the environmental impact of population growth. This study presents a literature-based assessment of CO₂ emissions from fossil fuel consumption in the context of sustainable development, with a focus on Europe. Recognizing the urgent threat posed by climate change, the paper explores how economic and demographic factors influence emissions trends and energy consumption. Through the synthesis of recent research and statistical data, it examines the relationship between economic activity and CO₂ emissions across EU countries. Special attention is given to national policy frameworks, particularly Germany’s “Energiewende”, as a successful example of emission reduction through building-sector reform. The study highlights that while economic growth remains a driver of emissions, strategic investments in renewable energy, energy efficiency, and sectoral transformation can decouple growth from environmental degradation. The findings support the need for country-specific mitigation strategies, emphasizing that uniform approaches may not address the diverse challenges faced by EU member states. This work contributes to the broader understanding of climate policy design by linking empirical evidence with policy implications in the transition to a low-carbon economy.

The mission of today's universities is to prepare the students properly to live and work in the 21st century. International research demonstrates the positive impact of using iPads in teaching. Successful deploying of mobile learning (m-learning) is not a matter of accident, but depends on users' acceptance of the technology. The purpose of this article is to create a mobile learning adoption pre-model tailored to the needs of a private university. To achieve this goal, valued adoption models were analyzed and, on their basis, the new model was created. The pre-model has been tested with a questionnaire. A paper-based survey was conducted among 640 students representing 25 countries. The questionnaire was grouped into sections: specifications of mobile devices owned by students and mobile internet access, expectation from mobile education application and attitudes towards current and future use of mobile devices in education. We computed all data with The Statistical Package for the Social Sciences - IBM SPSS Statistics version 25. The results of the research showed that the students from a central-eastern European University are technologically ready for mobile learning. Moreover, there appears to be no cause for concern regarding students from post-Soviet countries with respect to their competency to meet the demands of modern teaching in the form of mobile learning. Students have shown that they have clearly defined expectations for educational materials for mobile devices, which will be a challenge for the university when creating m-learning materials. Furthermore, students must feel the university's support in using mobile applications. That is why the teachers face a serious task: teachers must be prepared to show students the benefits of mobile learning, so they not only need to be trained but also convinced that it is worth using mobile learning.

In recent years, Europe has faced several major blackouts, exposing weaknesses in its energy infrastructure and raising serious concerns about the continent’s ability to manage such crises. As the shift toward sustainable energy accelerates, solar power has emerged as a critical component of this transition, not only for its environmental benefits but also because it is currently the most cost-effective method of electricity generation. Over the past two decades, the photovoltaic (PV) sector has experienced continuous growth to meet rising energy demands. Published scientific studies on the technology and implementation of photovoltaic panels mainly focus on the benefits and present case studies of success. The article aims to outline the current state of research on the danger of spontaneous ignition of photovoltaic panels. The analysis revealed the most common causes of PV self-ignition. Moreover, following consultations with experts in the field of photovoltaic panel installations, a scientific gap in this area was identified—to the authors’ knowledge, no one has written on this topic so far—the use of flammable materials in the form of hermetically sealed quick connectors. The research is based on a literature review, employing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method to perform a bibliometric analysis of papers published between 2013 and 2024. The Web of Science Core Collection (WoSCC) and the ScienceDirect database are used for this purpose. A total of 62 papers are selected for analysis and categorized based on five fields: keywords in a title and abstract, total number of citations per paper, total number of publications per journal, total number of publications per affiliation, and funding name.
