Southeast Asia Haze: Thailand Wildfire Emissions Hit Decade High Despite Regional Decline

Severe haze affected Southeast Asia in early 2026, with particulate matter levels frequently exceeding WHO guidelines in cities like Bangkok and Hanoi. While global biomass burning emissions were at a 24 year low, Thailand emerged as a major outlier with wildfire carbon emissions reaching their highest levels since 2016. Data from the Copernicus Atmosphere Monitoring Service shows that Thailand's April emissions totaled over 3 megatonnes. This spike contributed to hazardous air quality, highlighting a disconnect between broader regional trends and local wildfire activity.

Interesting that global fire emissions are down but Thailand is spiking. The data shows a clear gap between regional trends and what is happening on the ground in Thailand.

This is where policy intent hits a wall. You can have regional agreements on haze, but if the local incentives for land clearing remain, the emissions will keep spiking regardless of the global average.

The report mentions anthropogenic emissions as a major contributor alongside the fires. I wonder how much of this is industrial vs agricultural burning. Does CAMS break down the source of the PM2.5 beyond just biomass?

Usually these reports group them, but the mention of urban centers like Yangon and Hanoi suggests a heavy mix of traffic and industry making the wildfire smoke even worse.
