The paper analyzes the complex process of adopting environmentally sound technologies (EST) by identifying barriers that hinder this adoption, utilizing interpretive structural modeling (ISM) to establish a hierarchy and inter-relationships among these barriers. It emphasizes the critical role of technology transfer for sustainable development, especially in emerging economies like India, and aims to provide a structured approach for policymakers to navigate these barriers effectively. The study suggests that by understanding the interdependencies among barriers, resources can be leveraged optimally to facilitate the adoption of EST.
