Purpose This study investigates the impact of Inefficient Waste Disposal Systems on Kerala's Environmental Carbon Footprint and the role of Haritha Karma Sena in mitigating these negative effects. Methodology The study adopted a quantitative research design using a structured questionnaire to collect primary data from residents across selected regions in Kerala. Partial Least Squares Structural Equation Modeling (PLS-SEM) was employed to analyze the relationships among IWDS, ECF, and the moderating role of HKS. Reliability, validity, and hypothesis testing were conducted to ensure the robustness of the measurement and structural models. Findings The study reveals that inefficient waste disposal systems negatively impact the Environmental Carbon Footprint, while Haritha Karma Sena (HKS) effectively reduces environmental harm through community-driven waste management, thereby balancing the negative effects of IWDS.
