Pollution from smoke emitted by months of wildfires across Indonesia caused an estimated 3,560 deaths in the vast Southeast Asian archipelago in September, according to a new study.
The same month, about 57.8 million people in Indonesia were inhaling unhealthy to hazardous air, said the Centre for Research on Energy and Clean Air (CREA), a Helsinki-based think tank.
“Worsening air quality due to forest and land fires in Indonesia pushed the estimated death toll to 3,560 cases in September 2026, a twofold increase from the August estimate,” said a CREA statement on Thursday.
