This study intends to shed light on the environmental impacts of energy decisions in South Korea by analyzing the correlation between energy consumption patterns and environmental indicators such as carbon dioxide emissions. In 2021, global CO₂ emissions increased by 6%—to the highest ever level of 36.3 billion tons—according to the International Energy Agency (IEA). This increase in CO₂ emissions is a big problem for all countries around the world. The aim of this article is an analyze the impact of fossil fuels, renewable energy, and nuclear energy on South Korea’s environment based on the STIRPAT (stochastic impact by regression on population, affluence, and technology) model. Exploring the intricate nexus between economic and energy indicators and environmental outcomes, this study employs the STIRPAT model to analyze the influence of GDP, population dynamics, fossil fuels, renewable energy, and nuclear energy on South Korea’s environment. The yearly data from 1972 to 2021 are analyzed in this paper using an autoregressive distributed lag (ARDL) model. The reliability of this study is also examined by employing FMOLS (fully modified ordinary least squares) and CCR (canonical cointegrating regression) estimators. This study confirms the findings of previous research by showing that the rising South Korea GDP and population can lead to higher CO₂ emissions and that a strategy switching to renewable energy can cut down on CO₂ emissions in Korea, as it exhibits a coefficient of −0.085 *. The robustness results of FMOLS and CCR’s findings support baseline ARDL findings.

The business model is understood as a way of generating revenue and creating value. This article aimed to define the framework and detailed characteristics of the business model in corporate reporting in the energy sector. The study also addressed the issue of value creation and examined the correlation between reporting information about the business model and the value of the enterprise, calculated using selected accounting measures. The research was conducted in 2021 on all listed companies in the energy sector included in the WIG20 index in 2019–2020. The research methodologies included critical analysis of the literature, analysis of the content of corporate publications, comparative analysis, analysis of phenomena and synthesis of results, Spearman’s rank correlations, and graphical data presentation. The originality of our research concerns directing attention to the disclosure and reporting of information about the business model in corporate reports in the energy sector in Poland. This is the first such study in Poland conducted on companies in the energy sector; therefore, it is treated by the authors as a pilot study. The results show that companies in the energy sector included in the WIG20 index do not disclose information about their business models in reports and the structure of published reports is very diverse, which makes it even more difficult to compare financial and non-financial data. Enterprises in the energy sector disclose financial and non-financial information in financial statements and the reports of the management board on the activities of the company and the capital group. The financial information disclosed by the companies most often included financial and productive capital. Energy companies are reluctant to disclose information about by-products and waste.

The complementary currency Zielony (PLZ) is an example of an economic experiment, operating in Poland since 2015. It is also a new type of economic tool that supports the local economy and influences the creation of sustainable local developments. However, this impact is not direct, as it is realised through a network of micro, small and medium-sized enterprises operating in the local economy, which, among other things, create jobs relevant to the economic prosperity of the region and the life of the local community. The main objective of this article is to demonstrate the relationship between the use of the complementary currency Zielony in Poland by the entities that create the system of this currency and its impact on the economy, in particular on the local sustainable development in the pre-pandemic and pandemic period of Covid-19. The main research problem is formulated in the form of a question: “What are the benefits and opportunities for the economic entities of the local economy as a result of their accession to the complementary currency Zielony system?” The article adopts the following thesis: “The complementary currency Zielony in Poland positively influences the functioning of the local economy and the economic entities that belong to the system and promotes the creation of conditions that are important for sustainable local development. However, it works best when it is not disrupted by administrative barriers and lockdowns, like those that appeared in Poland during the Covid-19 pandemic.” The analysis carried out proved the validity of the thesis and allowed to solve the main problem. The study used the method of critical literature analysis and analysis of statistical data from 2015–2021.

Destructive market forces are multiplying as the world faces the worst global energy crisis in history. The continuing economic downturn and fluctuating oil prices, triggered by OPEC+’s plan to reduce supply, are slowing down global oil demand. In this respect, the situation in the transport services market is changing. Changes in the price of oil are indirectly influencing the formation of wholesale diesel prices; consequently, road freight should also change. However, are these changes correlative and do oil price fluctuations directly affect freight rate changes? This article aims to investigate the correlation between fluctuations in oil prices on world markets and their impact on wholesale diesel prices and, thus, the development of net road freight in Poland. In the study, the authors developed a model called “fuel adjustment,” containing the fluctuations in wholesale diesel prices, which were taken into account in determining the average deviation in the road freight level over the analyzed period. In this way, it became possible to determine the amount of road freight and its fluctuations depending on the development of oil prices on world markets. The results of the study confirm that there is a strong and positive relationship between the analyzed variables. When the prices of crude oil on world markets fall, this should be followed by reductions in diesel prices in individual countries, including Poland. Consequently, the amount of road freight should also have a downward trend. Will this happen?

Celem opracowania jest przedstawienie znaczenia interoperacyjności europejskiego transportu towarowego z uwzględnieniem wskazań i ograniczeń do jego stosowania, wynikających z polityki transportowej Unii Europejskiej (UE).W artykule zaprezentowano istotne kwestie związane z działaniami UE na rzecz zwiększenia konkurencyjności intermodalnego transportu towarowego względem innych gałęzi transportu. Na przykładzie danych statystycznych i ich porównań przedstawiono liczne korzyści, w tym: korzyści środowiskowe, emisyjne, jak również korzyści skali związane ze zrównoważonym rozwojem ekonomicznym, społecznym i terytorialnym wszystkich państw członkowskich UE. Przedstawione zostały również czynniki hamujące interoperacyjność europejskiego transportu intermodalnego oraz działania, które te czynniki mają ograniczyć, m.in.: wyrównanie poziomu infrastrukturalnego państw członkowskich, stworzenie wspólnego zarządzania przepływami towarowymi na terytorium UE oraz tworzenia partnerstwa wschodniego.
