This study evaluates the potential economic benefits of fully implementing EURO 4 fuel standards in Jakarta by 2030. Using ecological time-series data (2018–2023), the research analyzes associations between PM2.5 concentrations and National Health Insurance (BPJS Kesehatan) claims for air pollution-related diseases, including ischemic heart disease, pneumonia, COPD, and acute respiratory infections. The findings project substantial annual healthcare cost savings under a full EURO 4 scenario compared to Business-as-Usual conditions, highlighting the financial advantages of cleaner fuel adoption.

This proceeding is presented at APACPH 2025 and was supported by Yayasan Visi Indonesia Raya Emisi Nol Bersih (ViriyaENB).
