This paper quantifies the contemporary determinants (economic, social, environmental, and e-governance) for sustainable techno-societal development. E-governance has the potential to drive sustainable societal development by promoting economic, social, and environmental sustainability. It can improve efficiency, transparency, accessibility, and cost-effectiveness in government processes while contributing to environmental sustainability by reducing paper usage and carbon emissions. This study employed 320 techno-respondents from Southern Rajasthan, and the model was empirically evaluated with statistical tests. This study uses a multidimensional research approach to establish a meaningful relationship between economic, social, and environmental factors in achieving e-Governance for sustainable societal development. The research developed and supported the research model using Smart-PLS. Furthermore, e-governance can improve access to education, healthcare, and social services, improving quality of life and reducing social inequalities. Despite some limitations, e-governance can be a valuable tool for achieving sustainable societal development, and its future scope can further enhance its effectiveness in addressing society's complex challenges.
