The Chiang Mai Administrative Court ruled on Friday (19 January) that the Prime Minister and the National Environment Board must complete a management plan to address local air pollution issues in 90 days.

Academics, activists, medical professionals, and residents in Chiang Mai have filed a class action lawsuit against the Prime Minister and other government agencies for lack of action on air pollution, with the provincial capital now ranking among the world’s most polluted cities.

<p>Two myths created by the media caused misunderstandings. One is that Chiang Mai faced the most severe problem, and the second is that this problem is likely to increase in severity every year. Statistics over the past 24 years indicate otherwise.</p>

<p>In news reports less than 10 years ago, the new problem of PM2.5 dust was added to news items in the Thai media of forest fires and the problem of haze caused by forest fires and crop burning. This has led to a clear concrete policy shift, since it has a direct impact on the lives of the middle class in the country&rsquo;s large cities, especially major centres like Bangkok and tourist spots like Chiang Mai Province. With an unidentifiable origin, smog, forest fires and PM2.5 have by implication become the same thing.</p>

<p>Thailand&rsquo;s <a href="https://prachatai.com/english/node/8325">smog crisis</a> continues in Bangkok and other provinces for a second week, with pollution readings at hazardous levels, while the spokesperson of the Prime Minister&rsquo;s Office has insisted that the situation has yet to reach a crisis level and asks the public not to panic.</p>

<p>PM2.5 levels in Bangkok and surrounding provinces have reached a hazardous level for the third consecutive day on Friday (10 January), with the air quality measuring between 156 &ndash; 163 AQI (Air Quality Index), while the government has yet to issue any concrete long-term plan to tackle the issue.</p>
