2. Barriers and influencing factors in the implementation of circular economy in Slovenian road transportKristijan Brglez, Mateja Čuček, Andjelko Andy Kober, Rebeka Kovačič Lukman, 2024, original scientific article Abstract: The European Union’s commitment to sustainable development, exemplifed by the Green Deal and the United Nations Sustainable Development Goals, highlights the importance of the circular economy, especially for road transport companies. This study examines the current state of circular economy practices in Slovenian road transport through an inquiry of 151 logistic companies. Utilizing principal component analysis, fve key factors infuencing circular economy implementation were identifed: knowledge and competences, company practices, strategies, regional development, and market presence. Additionally, seven barriers were noted: lack of knowledge, fnancial constraints, time limitations, space constraints, limited technology, management issues, and supply chain coordination challenges. Findings suggest that circular practices are often secondary to business proftability, with fnancially stable companies more likely to adopt these practices. Success in circular economy implementation requires investments in innovative technologies, capacity building, and strong management support. Companies in more developed regions tend to adopt circular practices due to better access to knowledge and incentives. These insights provide a foundation for future research, including comparative studies across transport sector in European Union and globally.

4. A conceptual model for measuring a circular economy of seaports: a case study on Antwerp and Koper portsRebeka Kovačič Lukman, Kristijan Brglez, Damjan Krajnc, 2022, original scientific article Abstract: This paper introduces a conceptual model for evaluating seaports’ acceleration towards the circular economy. The model is based on the identification and definition of circular economy indicators, weighted according to the 9 R-strategy transitions towards the circular economy. We have employed the analytical hierarchy process for weight detection and further calculations of the final seaport circularity value. Our results suggest conceptual validity and provide a detailed insight into the circular activities of the seaports from the indicators, as well as 9 Rs and sustainability perspectives.

5. A conceptual model for a circular city : a case study of Maribor, SloveniaKristijan Brglez, Matjaž Perc, Rebeka Kovačič Lukman, 2024, original scientific article Abstract: Cities play a crucial role in achieving sustainable development. Decision-makers require assistance in developing city transformation plans amidst the emergence of various city models. A content analysis using concept mapping was conducted to examine smart, circular, and green city models. The analysis, supported by Leximancer, revealed that city models are evolving by adopting benefcial solutions from competitors, refecting a strong focus on sustainable development. Additionally, twentyfour research areas essential for implementing a circular city were identifed and validated. Furthermore, a conceptual model for a circular city was developed, incorporating the Defne-Measure-Analyse-Improve-Control tool and a problem-solving system. Testing the model on Maribor highlighted challenges in monitoring the transition towards circularity. The study validates the established model but emphasises the need for further research and case studies to verify its practicality. This scientifc research enhances the understanding of city models and their evolution towards sustainability, providing valuable insights for decision-makers and urban planners.

6. The complexity and interconnectedness of circular cities and the circular economy for sustainabilityKristijan Brglez, Matjaž Perc, Rebeka Kovačič Lukman, 2023, original scientific article Abstract: In our study, we are evaluating the dynamic interplay between circular cities and the circular economy, revealing connections shaped by new research insights, using Web of Science database. We have in depth analysed 671 publications from 1990 to mid- 2023, employing Leximancer and VOSviewer tools. Our analysis uncovered key themes, including buildings, waste management, value chains, and sustainable development, linking the circular cities concept and circular economy framework. Emerging research trends, such as urban metabolism, urban mining, governance models, the built environment, sustainability benchmarks, and value chain management, signify deliberate shifts towards higher circular development and implementation. These trajectories harmonise with overarching sustainable development goals. Contemporary research emphasises urban mining, circular indicators, adaptive resource reuse, and urban structure regeneration. This focus facilitates transitioning from linear models to heightened circularity within urban contexts. Research inclination is shifting from traditional economic and environmental concerns towards holistic urban configurations that prioritise social integration, communal well-being, and the dynamics of the social economy. Through this analytical expedition, we offer novel insights that enhance our understanding of the intricate symbiosis between circular cities and the circular economy. Our findings provide a scientific foundation for formulating targeted strategies by decision-makers and guiding urban landscapes towards transformative trajectories aligned with sustainable development objectives and sustainable cities.

7. Pregled posebnega poročila IPCC »Global Warming of 1.5 ºC«Kristijan Brglez, 2020, master's thesis/paper Abstract: Okoljska problematika je v zadnjih dveh desetletjih pridobila izjemno pozornost, ne le s strani gospodarskih subjektov in političnih organizacij, temveč tudi s strani širše javnosti. Za dobro pokritost le-te skrbi cela paleta mednarodnih organizacij, med katerimi je tudi naša obravnavana IPCC. IPCC na letni ravni izda posebna poročila, ki zajemajo določene teme, ki so v tistem trenutku pereče oz. odmevne. Prav tako je bilo v primeru posebnega poročila »Global Warming of 1.5 ºC«, ki je bilo izdano leta 2018 na konferenci v Incheon-u, v Republiki Južni Koreji. Čeprav so poročila pomembnega pomena za širjenje informacij, se je velikokrat pripetilo, da so le-ta postala tarča kritik; razlogi za to tičijo v pomanjkljivih informacijah in tudi v vmešavanju politike. Ta magistrska naloga analizira specifično tematiko poročila, in sicer predvsem vključenost CO2 in njegovih ekvivalentov v navezi s transportom v samem poročilu oz. njegovih referencah. Obenem bo obravnavano trenutno stanje raziskovanja iste tematike kot v poročilu (s pomočjo znanstvenih baz) ter s tem vpogled v trenutno stanje raziskovanja v primerjavi s tistim v poročilu.

8. Onesnaženost zraka s PM10 in PM2.5 delci v zaprtih in delno zaprtih parkirnih prostorihKristijan Brglez, 2017, bachelor thesis/paper Abstract: Onesnaženost zraka in zdravstvene posledice le-tega, pa tudi komplikacije z okoljem, ki so povezane z onesnaženostjo zraka, so vsekakor ena izmed najbolj perečih težav v zdajšnjem 21. stoletju. Kljub številnim ukrepom, s katerimi smo uspeli zmanjšati koncentracije žveplovega dioksida na razmeroma varne ravni, se trenutno ukvarjamo z novimi onesnaževalci zraka, predvsem z ozonom, s težkimi kovinami, kot tudi s PM10 in PM2.5 delci. Prav ti delci so bolj kot ozon nevarni za človekovo zdravje, saj nastajajo tako po naravnem postopku (gozdni požari), kot tudi zaradi človeških dejavnikov (promet, industrija itd.), s čimer smo jim mnogo bolj izpostavljeni v določenih situacijah, kot npr. ozonu. Ta diplomska naloga tako analizira predvsem povezave med koncentracijami delcev PM10 in PM2.5, ki nastajajo pri vožnji in parkiranju avtomobilov v različnih parkirnih prostorih, ki so lahko popolnoma zaprti ali le deloma zaprti, in kako sama konstrukcija vpliva na višino teh delcev.
