The paper analyses the environmental Kuznets curve relationship between greenhouse gases and chosen indicators of economic development based on the panel data of 20 countries of the EU in the period 2006–2013. Besides the typical variables, such as the share of a particular polluting industry, environmental taxes, energy taxes, research and development, the dummy variable of the crises and enterprise’s sustainability score were also included in the model. The fixed effect panel model was used as a framework for the analysis. The original contribution of this paper is that the factor referring to the enterprises’ sustainability was empirically tested in the expanded model. Higher energy taxes, research and development and the number of sustainable enterprises decrease the level of greenhouse gases. The size of agriculture, production and construction has a positive sign, which means that a higher value of the indicator is associated with a higher level of greenhouse gases. This implies that the analysed set of factors can be applied to adjust the trend in the region and might be useful for the climate change policy adjustment.

Understanding what are the IT sector’s business opportunities under distorted market conditions is a growing interest in sustainability research. This article investigates how to assess the IT sectors sustainability through a multicriterion assessment. For the assessment of the IT sector’s European and Slovenian competition policy, the DEMATEL technique was chosen. Fifteen economical performance indicators of IT sectors companies in 2015–2019 were selected for analysis. Given the multiplicity of criteria addressed in the sustainability issues, a multi-criteria analysis was used with the assistance of experts. In this research, the DEMATEL technique was developed for problem solving, for the assessment of the concentration of business entities that affect the competitive situation of economy. Results showed that comparison of the DEMATEL method with fuzzy and probability theories proved that it is possible to measure IT sector’s HHI-based performance.

The paper analyses the environmental Kuznets curve (EKC) relationship between greenhouse gases and main aspects of economic development based on the panel data of 20 countries of the EU, including the data of three Baltic States, in the period 1995–2011. The fixed effect panel model was used as a framework for the analysis. The commonly used models confirmed the presence of the inverse U-shaped relationship. The novel contribution of this paper is that the factor referring to the global financial crisis was tested in expanded EKC model. Higher energy taxes, primary production of nuclear heat and R&D decrease the level of greenhouse gas emissions (GHG). The size of agriculture, industry and construction, as well as the primary production of solid fuels have a positive sign, which means that a higher value of these indicators is associated with a higher level of GHG. This implies that the analysed set of factors can be applied to adjust the EKC trend in the region and might be useful for the climate change policy adjustment.

Background—competitive conditions are often distorted in the construction sector, therefore this affects the market position of all participants. This paper seeks to find the tools for properly assessment of participants by Herfindahl-Hirschmann index (HHI) and to identify what parameters have the greatest impact in the competitiveness of the construction sector. Methods: in this article the DEMATEL method was used whereas tool for assessing the balance of market concentration as it may help to determine factor with the greatest influence on a firm’s HHI. Results in this work showed how different parameters affect each other and their impact on a value of a firms’s HHI. When the parameters are determined, they can be useful for assesment of mergers their influence on the HHI and alteration of the market’s power balance. Conclusions—The calculation of the HHI by using the DEMATEL method allowed to check the empirical implementation check of the multicriteria assessment method, on the market power of business entities, operating in the distorted market conditions of the construction sector.

This study examines whether there is convergence in eco-innovation by comparing the circular economy practices of European Union Member States. The European Union Member States’ eco-innovation initiatives in the circular economy are the foundation for their interpretation of their relative efficiencies. In 2015, the European Commission granted sanction to the Circular Economy Package, in accordance with the European Union’s (EU) objective of transitioning to a low-carbon economy that is competitive, resource-efficient, and environmentally sustainable. This compilation includes legislative proposals and a comprehensive action plan for refuse management. Subsequently, in January 2018, additional measures were implemented to guarantee the successful implementation of the action plan. Concurrently, numerous European Union Member States implemented substantial strategies to facilitate this transition. The current systematic literature review is conducted using the “SALSA method”, which commences with a scoping search, progresses to an evaluation, and concludes with synthesis and analysis. Its purpose was to elucidate the circular economy practices and eco-innovation activities in the European Union. The objective of this assessment is to provide a concise overview of the most recent developments and initiatives that have been implemented in the European Union since the Circular Economy Package was adopted. Furthermore, it will evaluate the strategies implemented by particular Member States in this context. Methods of scientific literature analysis, including systematic, comparative, content analysis, grouping, comparison, SALSA, and TOPSIS methods, are used in this study.

The European Union (EU) has made eco-innovation and green technology a priority as they are essential to the continent’s long-term prosperity. To move towards sustainable economic growth, eco-innovation takes a significant role in the transition process. The aim of the article is to use the eco-innovation indicators as an instrument to measure the eco-innovation performance of Lithuania in the context of the EU Green Deal in order to analyze and assess the components and indicators of the eco-innovation index for Lithuania. Following the aim of the article, a set of research hypotheses will be formulated. The evaluation of eco-innovation indicators in Lithuania relative to EU countries using Eco-IS indicators, determination of eco-innovation efficiency using the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method, and identification of necessary eco-innovation policies for sustainable growth are the objectives of this paper. The research results present the positive impact of eco-innovation activities in the EU on Lithuania, and vice versa. Lithuania was affected positively by eco-innovation activities of other EU nations. The outcome of the study indicates its relevance by highlighting Lithuania’s position among the lowest countries in terms of eco-innovation adoption, hence new research pathways for the creation and implementation of policies to solve the current situation are provided.
