This study aimed to investigate the impact of Environmental Education on sustainability and the mediating role of Environmentally Friendly Supply Chain Efficiency (EFSC) and Fostered Environmental Knowledge (FENK). Employing a quantitative approach, data were collected from supply chain professionals who participated in Environmental Education programs. The research findings indicate a positive relationship between Environmental Education and supply chain sustainability. The study revealed that Environmental Education significantly enhances EFSC and FENK and positively influences sustainability practices within supply chains. The implications of this research are twofold. Firstly, it underscores the importance of incorporating Environmental Education as a fundamental component of supply chain management, contributing to more environmentally responsible practices. Secondly, the study highlights the mediating role of EFSC and FENK, indicating that not only does Environmental Education directly impact sustainability but also through the enhancement of these mediating factors. This research offers a novel perspective by establishing the link between Environmental Education, EFSC, FENK, and supply chain sustainability. However, certain limitations should be acknowledged, such as the potential for response bias and the need for further research to explore other potential mediators. Nevertheless, this study provides valuable insights for practitioners and policymakers seeking to promote sustainability in supply chains by emphasizing the role of Environmental Education and its interconnectedness with EFSC and FENK.

Several administrative areas in Bali are not ready for an effective spatial regulation for the tourism industry resulting in large-scale land conversion, including changes in productive agricultural land for tourism and other industrial needs. These changes allow environmental damage that threatens the performance and sustainability of tourism in Bali. The purpose of this study was to investigate the seven factors of ecotourism success, and their impacts on quality tourism experiences and sustainable tourism. The research was conducted in Bali by taking 200 samples from four village samples. The analysis used was Structure Equation Modeling (SEM) assisted by the Partial List Square (PLS) application. The results show that the research model yielded feasible Goodness of Fit. The results also show that ecotourism as a source of income was unable to support economic and infrastructure development. Community involvement had no significant impact on conservation efforts. Conservation had no impact on ecotourism performance. Services did not have any an impact on tourism performance. Thus, ecotourism as a source of income, community involvement, conservation and services as successful factors in improving ecotourism performance are strategic management priorities to build quality tourism experiences and sustainable tourism.
