Households face health risks requiring increased medical expenses; reduced outdoor activities harm tourism-dependent businesses; workers experience productivity losses; increased demand for air purification products and healthcare services; potential school/business closures increase household economic uncertainty.
Government likely to implement air quality emergency protocols, restrict industrial operations, issue health advisories, and potentially declare environmental disasters. May trigger transboundary pollution investigations with Indonesia. Possible acceleration of environmental regulations and enforcement of emissions standards. Insurance and liability claims may increase.
