Fire Smoke Took an Estimated 3,560 Lives in September
CREA, the Helsinki-based Centre for Research on Energy and Clean Air, estimates that air pollution caused about 5,310 deaths in Indonesia in September 2026, 42 percent more than in August. Fire smoke caused 3,560 of them, about twice the August figure, and accounted for 94 to 99 percent of deaths in four Kalimantan provinces and over 90 percent in Riau, Jambi and West Sumatra. On the worst day of the month 57.8 million people breathed unhealthy to hazardous air, a monthly record. CREA counts only deaths within days of exposure, and links the toll to a 75 percent cut in BNPB’s 2026 budget and the government’s refusal to declare a national disaster.
The Indonesian press release cites Agus Sari, co-founder and CEO of Landscape Indonesia and a member of the expert council of Perhimpunan Filantropi Indonesia, on the weak government preparation behind the smoke: the disaster was predictable and avoidable, and the lack of preparation comes down to a lack of will. NOAA issued its El Niño advisory on June 11, and Landscape set out the risk in Fire on the Horizon the same month. Our Highlighted Publication summarizes the analysis, redraws CREA’s figures, and sets its acute estimate beside the chronic toll and Landscape’s own health cost model.
