1. A game theoretic approach for plastic life cycle assessmentChunyan Si, Yee Van Fan, Lidija Čuček, Monika Dokl, Petar Varbanov, 2023, original scientific article Abstract: Plastic production and its end-of-life management pose a significant environmental footprint. The mitigation strategies of the plastic industry are comparatively attainable than the other hard-to-abate sector. However, the involvement of different stakeholders is needed. The life cycle analysis proposed in this study allocated the environmental footprint to stakeholders based on the game theory concept. It addresses the limitation of previous approaches that do not guarantee the stakeholders from different stages will participate in the initiatives with the lowest net environmental footprint due to the dissatisfaction or imbalance in the allocated unburdening footprint (benefit) and burdening footprint. The applicability of the proposed approach is demonstrated through a plastic recycling case study. An allocation of 82 % of environmental benefit to the producer, 14 % to the manufacturer, and 4 % to the user are suggested to achieve efficiency (lowest external interference) and stable cooperation (participation in recycling). This work serves as an initial assessment in demonstrating the integration of the game theory concept in environmental footprint allocation or Life Cycle Assessment.

2. A company’s carbon footprint and sustainable developmentJure Gramc, Rok Stropnik, Mitja Mori, 2022, original scientific article Abstract: Climate changes are already here. And they will get much worse in time. The main reason for global warming is GHG emissions from anthropological sources. That includes transportation, industry, electricity production, agriculture, and others. The European Union has introduced a new Green Deal as an answer to climate change. The European Green Deal puts more pressure on companies to mitigate their carbon footprint and implement sustainable development. One of the basic steps in the analysis of the environmental profile of a company is the identification of hot spots by using the carbon footprint methodology. The workflow of the carbon footprint calculation follows GHG Protocol standardised methodology. The calculation was made for a medium-sized company in the plastics industry. For all GHG emission sources, hot spots were identified and analysed. Based on the hot spots, sensitivity analysis for different pre-defined scenarios has been made, which are aligned with the company’s mid- and long-term sustainability goals. The three main hot spots of the company within scopes 1 and 2 are purchased heat, purchased electricity, and combustion of fuels in company vehicles. GHG emissions of heat and electricity are dependent on their distributor and their electricity and heat sources. The hot spot of scope 3 is purchased goods, especially plastic granulate. In the study, we focus only on scope 1 and scope 2.

3. Reviewing the narrative concerning the impact of population growth in AfricaCocou Marius Mensah, 2019, original scientific article Abstract: This article discusses the topic of population growth in Africa, a recurring theme in the era of climate change and the fight against CO2 emissions. The African continent is full of essential raw materials and encompasses the youngest population in the world. There is no doubt concerning the significant role it will play in global affairs, at a time when the world population is ageing, according to the UN statistics. In recent years, many policymakers have highlighted the necessity to deal with overpopulation, provoking moral controversial and basic human rights abuses. This article, however, proposes an opposite argumentation based on fresh data and emphasises the opportunities and challenges to take on, as the author considers "overpopulation" as more of a challenge than a sentence to underdevelopment. Though the paper mentions different issues linked to overpopulation, such as migration crisis, ecological sustainability and the UN Sustainable Development Goals, it concludes with a reminder of the importance of international cooperation as a solution to global issues.

4. Ecological footprint as indicator of students environmental awareness level at Faculties of Organizational Sciences, University of Belgrade and University of MariborNataša Petrović, Sonja Išljamović, Veljko Jeremić, Drago Vuk, Marjan Senegačnik, 2011, original scientific article Abstract: The Ecological Footprint is a complex sustainability indicator that answers a simple question: How much of the Earth’s resources is demanded to support humankind lifestyle and activities? Ecological Footprint translates consumption and waste flow data into a measurement of the biologically productive area required to sustain that flow. We used Ecological Footprint as input feature that provides an effective heuristic and pedagogic tool for capturing current human resource use. The key aspect of this paper will be focused on the measuring of environmental awareness level among the students of the Faculty of Organizational Science, University of Belgrade and University of Maribor. For the determining student’s environmental awareness level and their Ecological Footprint, we used a closed form questionnaire with 15 questions. Statistical analysis has been performed in SPSS software package.
Keywords: ecological footprint, environmental education, sustainability indicator, natural resources
