Voluntary engagement (VE) creates a sense of coordination and harmonization to share knowledge. The eminence of knowledge sharing (KS) for supply chain (SC) innovation is undeniable to initiate development in products, services, and operations. However, KS process is undergoing challenges in sustaining KS engagement by SC partners. Hence, recent researchers call for the need to address this gap in the literature to assess VE barriers. This paper studies the causal relationship of VE barriers on two MNCs, i.e., Toyota and Suzuki, via the fuzzy DEMATEL approach. The case examination findings indicate culture's alignment as the prime cause of VE and leadership commitment has stronger interdependence. The core problems which need elimination are fear of losing the job, prominence and opportunistic behavior. The study concludes that companies need to instigate the natural attributes of employees’ VE by setting-up earnest guidelines to practice free information and knowledge flow.

This study provides a data-driven analysis that illustrates a clear renewable energy depiction in sustainable energy security and unveils the regional issues due to the literature solely occupies energy security concept in the descriptions view, and renewable energy differences related to regions are rarely discussed. A hybrid method is proposed to valid those indicators and shows the trend of future studies. This study enriches the challenges and opportunities by contributing to understand the fundamental knowledge of renewable energy in sustainable energy security frontier, conveyance directions for future study and investigation, and assessment on global renewable energy position and regional disparities. There are valid 19 indicators, in which energy demand, energy policy, renewable resources, smart grid, and uncertainty representing the future trends. World regional comparison includes 115 countries/territories and categorized into five geographical regions. The result shows that those indicators have addressed different issues in the world regional comparison.

The significance of sustainability is continually expanding among researchers, policymakers, and decision makers. To improve the efficiency of value chain activities such as manufacturing, distribution, and consumption, an innovative research solution has been proposed: ‘Sustainable Consumption and Production (SCP) through Information and Communication Technology (ICT)'. Sustainability through ICT is significant for the industry in terms of its sustainable effects on production processes, environment, and community. This research seeks to gauge ICT—as knowledge management—for industries in the successful adoption and execution of SCP. In so doing, potential key ICT-based factors to SCP are identified from the literature and experts' feedback. The present work suggests a decision framework for assessing the interrelationships among and between the ICT oriented factors by utilizing graph theory and matrix approach. Data for this work derives from three automotive companies operating in India. From findings, ‘Governance and Management', is the topmost factor for the adoption of sustainable consumption and production in value chains. The relationship among the index values is further evaluated using Spearman's rank correlation coefficient. This research can facilitate practitioners, government agencies, and customers for a better understanding of ICT-driven factors in managing resources, reducing waste, and improving cost, which would further help in meeting sustainable development goals of the United Nations of responsible consumption and production and innovation, industry, and infrastructure.
