Decarbonizing Indonesian hospitals challenges and causal pathways toward sustainable healthcare

Abstract: The decarbonization of hospital infrastructure is a pivotal element in advancing climate-resilient healthcare systems, especially in developing regions. This study employs the Bayesian Best–Worst Method (BWM) to systematically identify and prioritize key barriers hindering hospital decarbonization in Banten Province, Indonesia. A total of 14 barriers were evaluated by domain experts based on their perceived criticality and interrelationship, using expert judgment aggregated through a Bayesian framework. The results highlight high initial investment costs (B7) as the most significant barrier, characterized by the highest mean weight (0.142) and dominant D − R value, indicating its status as a root cause requiring urgent intervention. Other top-ranked barriers include energy-inefficient devices (B4), lack of supportive regulation (B3), and absence of decarbonization targets (B2), reflecting systemic and institutional constraints. The integration of D-R analysis with Bayesian weights enables a robust mapping of barrier typologies and facilitates the development of quadrant-based strategic recommendations. Implications for Banten Province include the need for green financing schemes, regulatory reform, energy-efficient procurement standards, and enhanced capacity building in sustainable hospital management. The study contributes to the growing body of research in sustainable healthcare by offering a transparent, replicable prioritization method, while also acknowledging contextual limitations such as sample representativeness and evolving policy landscapes. These findings provide a practical decision-support tool for policymakers aiming to accelerate low-carbon transitions in the healthcare sector.
