ABSTRACT
The incomplete resource efficiency of oil and gas (O&G) companies in their imperfect corporate reporting is a relatively new topic gathering researchers' attention because of the increased importance of environmental concerns. The main aim of this article is to aid researchers in understanding the overall trends and shifts in exploring a novel sustainable development method for O&G companies and evaluating it using the example of Lukoil and Gazprom. The study uses a trend analysis method to examine the dynamics of Brent prices to recognise causal connections between the COVID-19 crisis of 2020 and the sanctions crisis of 2022 and their impact on O&G companies' sustainability. Subsequently, the article conducts a quantitative and qualitative study to combine qualitative information on pandemic models with quantitative dynamics of Brent prices and identify their relationship. This article develops a sustainable development method for O&G companies, the novel nature of which consists of digital intellectual monitoring of the sustainability of these companies in public policy practices on Industry 4.0. The article also suggests potential research directions for AI applications to automatically track intelligent data analytic capabilities. The significant findings of this study show that this approach allows for total market coverage and rational decision-making by state regulators and the attentive public. This new method offers a proprietary algorithm and recommendations for energy companies on improving corporate accounting and development of resources policy, assessed using the example of Lukoil and Gazprom.
ABSTRACT
Background: The current coronavirus disease 2019 (COVID-19) pandemic has stressed why a change towards resilient, robust and sustainable supply chains is more imperative than ever. This is especially true for supply chains of perishable foods, where issues such as the bullwhip effect cause not only economic but also environmental damage.Objectives: The key objectives of this study are to gain a deeper insight into correlations regarding the causes of the bullwhip effect and to see how a sinusoidal stimulus is affecting the generation of food waste. Method: A simplified beef food chain was modelled in Tecnomatix Plant Simulation®. As the bullwhip effect consists of a simplified parameterisation of an excitation duration (period length) and its height (amplitude), these two variables were used to generate a sinusoidal stimulus. The simulation results were statistically verified and checked for commonalities and differences with the already established scientific knowledge. Results: While the expected higher sensitivity of the front links of the supply chain to waste generation can be confirmed, the results of a long stimulation period suggest that the negative effects of the bullwhip effect do not increase indefinitely. Conclusion: The analysis of the results has shown that previous theories can be transferred, but that the variation of the variables entails new insights for the interdependencies of the amplitude and period length and their influence on the output variable waste. Contribution: The study contributes to a more holistic understanding of the bullwhip effect and, in particular, its implications within a perishable food supply chain. © 2023. The Authors.

ABSTRACT
Digitalization has the potential to hasten the economic transition towards a more resource-efficient as well as robust circular production system. However, there is a paucity of empirical research on the influence that digitalization has on the ability of a circular economy to function effectively. The objective of this study was to investigate the effect that digitalization has on the performance of the circular economy. The research was based on an empirical analysis of quantitative data obtained from a sample size of 200 investors and entrepreneurs in the financial sector of Kozani, Greece. Regression results showed that there is a positive relationship between digital practices and performance of a circular economy, and that digital business innovations have a positive effect on performance of a circular economy. Even while a sizeable proportion of Greek companies apply new business innovations to support the strategy of resource efficiency, it is abundantly obvious that this percentage is far higher among industrial organizations that place a heavy focus on digitalization. According to the findings of the research, there is a favorable correlation between the adoption of digital business practices and innovations and the success of circular economies. This demonstrates very clearly that digitalization has the potential to function as a driving force behind the development of circular business models.
ABSTRACT
Today, changing framework conditions of living and working in cities drive urban planning processes for refurbishment, notably at the level of neighbourhoods, and provide a window of opportunity to enhance resource efficiency and sustainable urban development. Indicators, as part of sustainability assessment methods, may support the identification of the most beneficial planning alternatives or the selection of measures. However, the fact that a multitude of indicators are proposed in the literature discourages their actual use and hampers a sound application for decision support. To tackle these challenges, a manual has been developed proposing a framework for the use of indicators in urban planning. In this contribution, the theoretical foundations of the proposed framework are analysed. A conceptual outline of the framework is presented, which as its core has a typology of indicators, and its embedding in urban planning processes is discussed. The framework combines a theoretically concise unifying structure with a flexible practical approach for application in diverse areas of resource efficiency. Thus, it shall enhance transparency as well as comparability in the use of indicators, foster communication between stakeholders and in the long run support the application of indicators and use of sustainability assessment methods as regular parts of urban planning.
ABSTRACT
Plastic waste (PW) is one of the most rapid-growing waste streams in municipal solid waste all over the world. India has become a global player in the plastic value chain. Despite low consumption, domestic generation and imports create a significant burden on the overall waste management system, which requires in-depth understanding of the scenario and pathways that can mitigate the crisis. Although Indian researchers have widely researched technology-related issues in academic papers, a substantial knowledge gap exists in understanding the problem’s depth and possible solutions. This review article focuses on current plastic production, consumption, and waste generation in India. This review article mainly analyzes data and information regarding Indian PW management and highlights some critical issues such as reverse supply chain, effective PW management, source-specific recovery, and PW rules in India. Comprehensively, this review will help to identify implementable strategies for policymakers and research opportunities for future researchers in holistic PW management and recycling in India, focusing on the circular economy and sustainable development goals.
