Instrument validation for measuring environmental sustainability performance in the energy sector of Malaysia

United Nations' SDG goals highlighted the importance of conducting behavioral studies on employee energy usage (12th SGD Agenda) due to increasing environmental issues and global sustainability practices for current and future generations. This study aims to better understand the phenomenon of sustainable consumption behavior by incorporating pro-environmental culture and the impact of workplace spirituality. The focus and scope of this study will be on behavioral studies and organizational interactions in Malaysia's energy sector to attain environmental sustainability performance through individual employee contributions. The value-belief-norm theory of environmentalism supports the conceptual model. The study adds both theoretical and empirical knowledge to the body of knowledge, which makes it significant. The link has been analyzed in study design using quantitative methodologies. Survey-based method of primary data has been used to collect from energy sector employees. A total of 104 employees in the energy sector participated in the pilot testing. With the support of real-world implications and suggestions, practitioners and policymakers will find it simpler to comprehend behavioral phenomena and establish sustainable goals to accomplish environmental sustainability performance.
