Requirements for establishing energy hubs : practical perspective
Mahmoud A. Hammad, Sara El Gazzar, Borut Jereb, Marjan Sternad, 2023, original scientific article

Abstract: The global economy has barely begun to recover from the effects of the COVID-19 pandemic, only to be thrown into a new crisis because of the Russian-Ukrainian war. The war exacerbated the energy problem by causing a shortage of energy supplies for the EU and other countries, affecting quality of life. As a result, establishing energy hubs for collecting, processing, storing, and transiting energy resources between producing and consuming countries has become imperative to manage energy supplies efficiently. However, previous studies have not yet addressed the requirements for setting up energy hubs from a practical point of view. Therefore, this paper investigates the requirements for the establishment of energy hubs, particularly for oil and gas, from a practical perspective. The researchers conducted 13 semi-structured interviews with different energy stakeholders. Using the SWOT analysis matrix tool, the findings assessed the current state of the global oil and gas market, and the main practical requirements for the establishment of energy hubs were identified, along with the elements for implementation. Furthermore, the article highlighted the most pressing practical issues confronting the establishment of energy centres. Finally, the paper laid out a comprehensive practical framework based on the industry practitioners’ views to help establish energy hubs. The framework provides a possible guide for countries to establish energy hubs based on the main requirements outlined in this study. It can also improve the diversity, flexibility, and security of energy supply, especially for countries that rely on sole suppliers, such as the EU.
Keywords: energy hubs, energy stakeholders, diversification of energy supplies, security and sustainability of energy supply, European Union countries, Russian-Ukrainian war

Blockchain technology adoption for improved environmental supply chain performance : the mediation effect of supply chain resilience, customer integration, and green customer information sharing
Summer K. Mohamed, Sandra Haddad, Mahmoud Barakat, Bojan Rosi, 2023, original scientific article

Abstract: Due to the complexity of building supply chain resilience (SCR) towards long-term environmental sustainability amendments, the use of emerging technologies such as Blockchain Technology (BCT) can be adopted as an innovative tool to enhance the sustainability and resilience of supply chains, especially in uncertain environments. Drawing on the Knowledge-Based View (KBV) and Dynamic Capability View (DCV), this research aims to demonstrate how the adoption of BCT can enhance the environmental supply chain performance (SCP). A total of 603 valid surveys were collected from respondents from manufacturing and service organizations in Egypt. The collected data were analyzed using structural equation modelling, and results revealed that BCT adoption alone had a negative direct impact on environmental SCP. However, when this relationship was mediated by SCR and sequentially mediated by customer integration and green customer information sharing, the results were positive. This research presents insights on how organizations can adapt to dynamic business environments, and, in addition, it extends the theories of KBV and DCV in an empirical contribution by filling the gap in understanding regarding how environmental SCP can be enhanced through the adoption of BCT.

Assessment of environmental sustainability integration into higher education for future experts and leaders
Matevž Obrecht, Zane Feodorova, Maja Rosi, 2022, original scientific article

Abstract: The environmental and climate crisis is gaining priority among critical human concerns; therefore, environmental knowledge and sustainable solutions play a significant role and gaining global popularity as an academic discipline. Additionally, United Nations Sustainable Development Goal no. 4 acknowledges education's role in promoting sustainable development, sustainable lifestyles, human rights, social responsibility, circular economy, and greening our economy and society. In this paper new conceptual framework that focuses on systematically analyzing environmental sustainability integration in study programs and subjects is developed. The main aim is to reflect the conceptual basis of education related to environmental sustainability topics such as sustainable development, social responsibility, circular economy, ecology, environmental protection, and greening to boost future environmental management practices in industry and services. Defining the level of integration of environmental and sustainability-related topics is divided by research field classification and study cycles (BSc, MSc, PhD). The specific added value of the developed conceptual framework is reflected by defining cross-sections and inter-and trans-disciplinary of sustainability topics integrated within specific programs and subjects. The conceptual framework was tested by assessing 1051 programs in progress in Slovenia. It was revealed that the highest share of study programs has an intermediate level of environmental sustainability with 2–3 subjects (392 study programs). These are represented mainly by integrating environmental protection, ecology, and “greening” but less with circular economy and social responsibility. Significant differences among specific study programs and study fields reflect that young intellectuals will not be equally educated and qualified for future managerial challenges. Master students gain the best insight into core sustainability and environmental topics needed for future environmental managers.

Integrating social dimensions into future sustainable energy supply networks
Matevž Obrecht, Yigit Kazancoglu, Matjaž Denac, 2020, original scientific article

Abstract: Environmental protection and sustainable development have become an inevitable trend in many areas, including the energy industry. The development of energy supply networks is strongly correlated with the economics of energy sources as well as ecological and socio-political issues. However, the energy supply network is often distant from the social perspective. This paper therefore combines examination of perceptions and awareness of general public (web-based questionnaire) and top energy experts (a Delphi survey) on the energy supply network and identifies their potential integration in energy supply decision making processes. The results showed that public should be better informed as well as integrated into designing energy supply network as the prosumers gain power and the energy suppliers will no longer dominate the market. Public actors are ready to shape sustainable energy supply and also willing to pay 5.8% more for a sustainable energy supply. The majority are prepared to invest in renewable energy supply network close to their place of residence. Another result is that the public is calling for a shift in priority towards more sustainable and socially friendlier energy supply rather than focusing mainly on the economic and technical perspectives.

Sustainability orientation and focus in logistics and supply chains
Sebastjan Lazar, Dorota Klimecka-Tatar, Matevž Obrecht, 2021, original scientific article

Abstract: Sustainable development, logistics, and supply chain are being combined into three increasingly connected and topical global research areas. Therefore, this paper's novelty identifies and defines the priorities of the UN Sustainable Development Goals and sustainable development dimensions in supply-chain- and logistics-management-related studies in the last decade. Knowing logistics and supply chain sustainability focus and orientation is valuable information for researchers and managers to adapt and mitigate their business logistics according to the forecasted trends. The paper provides a systematic and comprehensive review of the literature and is based on 116 scientific papers published between 2010 and 2020 in 73 international journals in the Scopus and Web of Science databases. The study defines focus with integrating environmental, social, and economic sustainability for logistics- and supply-chain-related studies. It emphasizes primary and secondary links of investigated studies with 17 United Nations sustainable development goals. The bibliometric analysis also examined keyword relations. One of the main contributions is that economic sustainability was identified as the most represented one-dimensional sustainability focus. It was revealed that supply chain studies integrated all three sustainability dimensions more frequently (50.60%) than logistics studies, which were equally related to studying two- or three-dimensions of sustainability (39.39%). The most significant findings are also that studies were identified to be oriented primarily towards "responsible consumption and production", "industry, innovation, and infrastructure" and "affordable and clean energy" and secondary especially on "sustainable cities and communities".

Sustainable operations of last mile logistics based on machine learning processes
Jerko Oršič, Borut Jereb, Matevž Obrecht, 2022, original scientific article

Abstract: The last-mile logistics is regarded as one of the least efficient, most expensive, and polluting part of the entire supply chain and has a significant impact and consequences on sustainable delivery operations. The leading business model in e-commerce called Attended Home Delivery is the most expensive and demanding when a short delivery window is mutually agreed upon with the customer, decreasing possible optimizing flexibility. On the other hand, last-mile logistics is changing as decisions should be made in real time. This paper is focused on the proposed solution of sustainability opportunities in Attended Home Delivery, where we use a new approach to achieve more sustainable deliveries with machine learning forecasts based on real-time data, different dynamic route planning algorithms, tracking logistics events, fleet capacities and other relevant data. The developed model proposes to influence customers to choose a more sustainable delivery time window with important sustainability benefits based on machine learning to predict accurate time windows with real-time data influence. At the same time, better utilization of vehicles, less congestion, and fewer failures at home delivery are achieved. More sustainable routes are selected in the preplanning process due to predicted traffic or other circumstances. Increasing time slots from 2 to 4 h makes it possible to improve travel distance by about 5.5% and decrease cost by 11% if we assume that only 20% of customers agree to larger time slots.

Supply chain management mitigation to climate change in three selected industrial sectors
Maja Bašić, Špela Kovše, Andraž Opačić, Marijana Pećarević, Matevž Obrecht, 2023, original scientific article

Abstract: As the world economy is growing and globalisation is on the rise, climate change and its effects on the planet Earth are also increasing. But climate changes do not disturb only nature; they also affect businesses and their supply chains. Many companies have recently recognised the positive impacts of green and circular supply chain management practices. Supply chains that deliver products from around the world are increasingly exposed to the impacts of a changing climate and scarce resources. In this research, it was determined how climate change impacts supply chains in the food, automobile, and energy industry sectors. Furthermore, we wanted to find out if and how the management of supply chains is altered to adapt to the business environment which is more and more affected by environmental changes.

Energy indicators and topics in food supply chains' life cycle assessment
Petra Vidergar, Rebeka Kovačič Lukman, 2019, original scientific article

Abstract: Food supply chains have a significant impact on the environment, using large amounts of fossil energy resources and other non-renewable resources. Energy is directly and indirectly needed in all the steps along the food supply chain. This paper explores energy-related indicators in food supply chains and life cycle assessment within sixty-six research papers, gathered from the Web of Science database. Furthermore, a quantitative content analysis was carried out to assess the research trends and future opportunities regarding energy-related topics. The results revealed that a holistic perspective is needed, as energy-related indicators should be included in the use and end-of-life stages, not only in the production processes, and that the inclusion should follow the life cycle assessment methodology. The current research topics are energy issues related to production processes and environmental impacts. Improvements are possible in extending research areas to renewable resources, whole lifecycle perspectives, and socio-economic consequences.

Towards trusted data sharing and exchange in agro-food supply chains: design principles for agricultural data spaces
Martina Šestak, Daniel Copot, original scientific article

Abstract: In the modern agricultural landscape, realizing data’s full potential requires a unified infrastructure where stakeholders collaborate and share their data to gain insights and create business value. The agricultural data ecosystem (ADE) serves as a crucial socio-technical infrastructure, aggregating diverse data from various platforms and, thus, advertising sustainable agriculture and digitalization. Establishing trustworthy data sharing and exchange in agro-food value chains involves socioeconomic and technological elements addressed by the agricultural data space (ADS) and its trust principles. This paper outlines key challenges to data sharing in agro-food chains impeding ADE establishment based on the review of 27 studies in scientific literature. Challenges mainly arise from stakeholders’ mistrust in the data-sharing process, inadequate data access and use policies, and unclear data ownership agreements. In the ADE context, interoperability is a particularly challenging topic for ensuring the long-term sustainability of the system. Considering these challenges and data space principles and building blocks, we propose a set of design principles for ADS design and implementation that aim to mitigate the adverse impact of these challenges and facilitate agricultural data sharing and exchange.

Sustainability topics integration in supply chain and logistics higher education : where is the Middle East?
Maja Rosi, Matevž Obrecht, 2023, original scientific article

Abstract: The global logistics industry has grown significantly in the last decade and has become essential to global business activities. In addition, the logistics industry is vital in transportation, urbanization in the Middle East, and transshipment through the Middle East. Due to their increasing importance and size, there is an increasing demand for adequately qualified people capable of managing the logistics systems and supply chains holistically and sustainably to avoid problems caused by unsustainable practices in mobility, transport, and supply chains. However, it is unclear whether the logistic and supply chain education of future leaders, managers, and engineers will follow SDG goals, the rise of new trends, and green technologies or lag behind. This paper pioneered a systematic approach and analyzed Middle Eastern countries regarding their sustainability integration into higher education programs related to supply chain management and logistics studies. It revealed enormous differences among countries and a lack of sustainability topics in most studied countries. Some countries are also significantly more oriented toward partial logistics challenges such as transport efficiency instead of sustainable supply chains, which are becoming critical challenges for the near future and must be accompanied by formal and life-long learning on sustainability-related topics. The circular economy and corporate social responsibility are especially neglected. It was also revealed that sustainability integration in higher education does not correlate with sustainability scores and the ranking of countries within the sustainability index.
