Circular economy (CE) practices have emerged as an essential alternative to the traditional linear “take, make, dispose” economic model. In emerging economies like India, where rapid industrialization and urbanization coincide with severe environmental degradation and resource constraints, transitioning to a circular model is increasingly critical. This study investigates the integration of CE practices into sustainability operations in India, focusing on their effects on resource efficiency, waste reduction, and greenhouse gas (GHG) emissions. A mixed‐methods research design was employed, combining a systematic quantitative analysis with in‐depth qualitative case studies and stakeholder interviews. Quantitative findings reveal that organizations adopting CE strategies exhibit, on average, a 20% improvement in resource efficiency and an 18% reduction in waste generation. Qualitative insights explain that robust regulatory frameworks, technological innovations, and strong stakeholder collaboration are key enablers of successful CE integration. However, challenges such as fragmented policies, high capital costs, and limited public awareness persist. The paper reviews and critiques recent literature to identify unsolved problems and research gaps, demonstrating the novelty of the present work. Policy and practical recommendations are provided to guide future interventions. This study contributes to the academic discourse on sustainable development by offering empirical evidence and a comprehensive framework that supports the transition from linear to circular economic models in emerging markets.
