The Hungarian Constitutional Court’s Decision on the Protection of Groundwater Decision No. 13/2018. (IX. 4.) AB of the Constitutional Court of Hungary

Gábor Kecskés

Publication Name: Hungarian Yearbook of International Law and European Law

Publication Date: 2020-01-01

Volume: 8

Issue: 1

Page Range: 371-382

Description:

On 28 August 2018, the Constitutional Court of Hungary delivered a milestone decision [Decision No. 13/2018. (IX. 4.) AB] in relation to the protection of groundwater with reference to the general protection of the environment as a constitutionally protected value. The President of the Republic pointed out in his petition to the Constitutional Court that two sections of the draft legislation are contrary to the Fundamental Law by violating Articles B(1), P(1) and XXI(1) of the Fundamental Law by permitting water abstraction with much lower standards. Adopted by the majority along with concurring and dissenting opinions, the decision is an important judicial achievement in the general framework of constitutional water and environmental protection. It also confirms the non-derogation principle elaborated by the Constitutional Court. The Constitutional Court had the opportunity and an ‘open mind’ to take into consideration numerous sources of scientific professional evidence on the stock of water and groundwater abstraction. The decision was acclaimed for its environmental orientation, and even more, for developing the 25-year old standards of constitutional review in environmental matters by elaborating on the implicit substance of several articles enshrined in the new Fundamental Law (e.g. Articles P and XXI).

The spatial extent of the operations of small and medium-sized companies in Győr based on the personal evaluation of the executives

Adrienn Reisinger Norbert Kovács

Publication Name: Teruleti Statisztika

Publication Date: 2024-01-01

Volume: 64

Issue: 5

Page Range: 661-686

Description:

Economic processes from territorial perspective can be analyzed using various approaches such as identifying the territorial levels at which firms operate. This involves understanding where firms source their inputs from, the location of their markets and the extent of their relations with stakeholders. The paper aims to measure the spatial extent of firms based on a personal perception of small- and medium-sized enterprises’ (SMEs) owner-managers. Based on structured interviews in 2021–2022 with thirty SMEs in Győr, Hungary the paper looks for the answer to what is the spatial extent of the operations of the surveyed firms in the dimensions of inputs, outputs, relationships and corporate impacts? Exception of one of the surveyed companies, all of them are present at least at the regional level and some of them have already entered international markets as well. Firms are mostly considered local in the case of the workforce, while stocks are mainly purchased from international markets. The results of the research characterize the spatial extent of the firms, which can serve as useful information about the territorial role of SMEs for both practitioners and scholars.

Leveraging Forest Resources, Green Energy, and Digitalization: Contextual Evidence Apropos Sustainable Growth in the Lens of Climate Resilience Policies

Li Junwen Mohd Ziaur Rehman Urszula Mentel Péter Németh Kamil Gemra Péter Németh Li Junwen

Publication Name: Land Degradation and Development

Publication Date: 2026-05-30

Volume: 37

Issue: 9

Page Range: 4411-4425

Description:

Sustainable forest landscape, digitalization, and green energy are the core pillars of the European Union's policies to achieve sustainable growth; however, their impacts are divergent due to variant regional forest management policies, economic structures, and digital transformation. This study contributes to the literature by uniquely evaluating the asymmetric impacts of forest access, green energy, and digitalization on sustainable growth across the EU countries from 1991 to 2022. It introduces the moderating role of digitalization on forest access, a dimension that has been unexplored previously. This analysis employs the method of moments quantile regression (MMQR) to address the slope heterogeneity and cross-sectional problems. The outcomes exhibit that green energy and digitalization are the drivers of sustainable growth, while their effects are pronounced at higher and lower growth quantiles, respectively. In contrast, forest access inhibits economic sustainability, with larger impacts realized in high-growth economies. The interaction term indicates that the applications of digital technologies in the forest landscape significantly support sustainable growth. The robustness analysis confirms the consistency of regression outcomes. These insights offer novel implications for EU climate and digital policy integration under the Green Deal and REPower EU agenda.

Linking digital platform design to circular supply chains: Evidence from knowledge sharing and collaboration mechanisms

Judit Petra Koltai Varun Chotia Shivani Agarwal Dezhen Li Rsha Alghafes

Publication Name: Technology in Society

Publication Date: 2026-06-01

Volume: 86

Issue: Unknown

Page Range: Unknown

Description:

Digital platforms are increasingly central to circular economy transitions, yet it remains unclear how platform design translates into measurable circular outcomes. This study addresses this gap by developing a socio-technical framework that explains how digital platform information transparency and interoperability enable circular value creation. Drawing on socio-technical systems theory, platform governance, and the dynamic capabilities perspective, the study conceptualizes platform design features as layered affordances that operate through governance and knowledge-based mechanisms. Using survey data from platform-enabled supply chain actors and analysing the model via PLS-SEM, the findings reveal that transparency and interoperability significantly enhance sustainability governance mechanisms, while transparency strengthens knowledge sharing intensity and interoperability supports collaborative decision-making. Sustainability governance mechanisms, in turn, drive both circular business model implementation and circular supply chain performance, whereas knowledge sharing intensity primarily supports business model transformation. Notably, collaborative decision-making does not directly improve circular supply chain performance, suggesting that collaboration without governance alignment remains insufficient. By unpacking the indirect pathways through which platform design shapes circular outcomes, the study advances platform governance and circular supply chain literature. It offers actionable insights for managers and policymakers seeking to design digital ecosystems that move beyond symbolic digitalization toward measurable circular performance and systemic value creation.

MXene/TiO2 Photocatalyst: The Key Role of MXene Electron Trapping in Water and Air Treatment

László Janovák Zsolt Pap Ágota Deák Gergő Ballai Áron Ágoston Szabolcs Kocsis Szurke Karolina Solymos Laura Lakatos Szabolcs Kocsis Szürke Szabolcs Kocsis Szürke Ákos Kukovecz Zoltán Kónya

Description:

The photocatalytic activity of TiO2 can be increased by incorporating it into a composite with an electron-trapping co-catalyst. MXene can perform this task as an electron-conducting material. In addition to trapping electrons, it also affects the defects in TiO2 near the interface. To screen for the best photocatalytic performance, three types of composites were prepared: by physical mixing, chemical deposition, and ALD. During characterization, the structural, optical, and photoelectrochemical properties were determined. Photocatalytic activity was examined in suspension (phenol conversion) and on a layer (gas phase ethanol conversion). It was found that the composite containing the lowest proportion of cocatalyst (1 wt.%) had the highest photocatalytic activity. According to the results of photocatalytic activity measured in suspension, the physical mixtures were proven to be more effective than neat TiO2, with the composites converting approximately the total amount of phenol in ~40 min, while TiO2 required ~80–90 min to do so under the same conditions. Thus, the electron-trapping role of MXene is clearly demonstrated in suspension applications, which is also confirmed by other characterization methods (photoluminescence, photocurrent density). TiO2 performed best during ethanol conversion, as it has the highest ethanol adsorption capacity (33.41%). During ethanol conversion tests, the MXene electron-trapping property was most effectively demonstrated in composites formed using the ALD method.

Financial subsidies and the location decision of solar power plants in Hungary: An empirical investigation

Mihály Lados Tamás Tóth Éva Szabina Somossy

Publication Name: Regional Statistics

Publication Date: 2020-01-01

Volume: 10

Issue: 2

Page Range: 166-185

Description:

Recent years have witnessed a significant increase in the number of solar power plants worldwide, including in the European Union. In Hungary, solar capacities have increased tenfold in the past three years, primarily due to the lower cost of solar technology and the favourable investment environment. The integration of these weather-dependent power plants into the electricity system, hitherto, has not been a problem in Hungary. However the expected increase in capacity over the next decade may cause grid problems, implying that the decision about the location of solar power plants is not a secondary issue. Hence, this study examines the factors that impact investors’ choice of the optimal installation site and the extent to which financial assistance, primarily operating support, influence this installation decision. This type of research has not yet been undertaken in the Hungarian context. Therefore, our research – based on a questionnaire survey conducted in March 2018 – fills an important gap. In contrast to the conclusions of the extant literature covering other countries, in the case of solar power plants in Hungary the installation location is not based on natural factors (e.g. irradiation) but on the marketability and price of electricity – classified in the financial support category – as well as the network connection options. Additionally, operating support may influence the location of solar power plant installation, which can be used as valuable information for regulation in the course of further expansion of the domestic photovoltaic power generation.
