How could the toxic haze from Indonesian fires affect Singapore?
Singapore may face air quality challenges from transboundary haze. The massive peatland wildfires in Indonesia, fueled by a record-breaking El Niño, are releasing a toxic haze that engulfs much of Southeast Asia. This haze, which is also releasing an estimated 190 million tons of carbon this year, poses a risk to air quality in Singapore. While the reports do not detail specific operational impacts on Singapore, the transboundary nature of the haze means that air quality degradation is a likely consequence of the ongoing blazes.

How it reaches Singapore
-
The World Meteorological Organization reported that peatland wildfires in Indonesia, fueled by a record-breaking El Niño, released massive amounts of carbon into the atmosphere. So far this year, these fires have released an estimated 190 million tons of carbon, which is roughly three-quarters of Indonesia’s annual CO2 emissions from burning fossil fuels. The WMO also published a report showing that global CO2 levels rose by 2.8 ppm between 2024 and 2025.
The full event1independent outlet -
The toxic haze generated by the Indonesian blazes is described as engulfing Indonesia and much of Southeast Asia, placing Singapore within the affected geographical area. The transboundary nature of the haze means that Singapore could experience reduced air quality and potential operational disruptions due to the pollutants carried across the region.

Why it matters
Air quality is a critical public health concern for Singapore, and transboundary haze events pose a recurring threat to the nation's citizens and economic activity. The fires are exacerbated by El Niño-driven drought, which sets the stage for the flammability of peatlands already degraded by deforestation and drainage.
This situation is part of a larger climate pattern where El Niño alters weather, reduces plant growth, and increases fire activity across tropical regions. This contributes to greater increases in atmospheric CO2 concentrations compared to non-El Niño years, linking local environmental crises to global climate trends.
