What is the Transboundary Haze Pollution Act?
Transboundary Haze Pollution Act (THPA) is a law enacted in 2014 that allows the Government to prosecute companies (within or outside Singapore) that cause or contribute to haze pollution. Individuals and businesses harmed by the haze can also sue companies under this Act.
How is THPA triggered?
When PSI stays at 101 or above for 24 continuous hours. In 2026, this threshold was first crossed on 4 September. We are currently experiencing the longest stretch of unhealthy air quality, with PSI above 101 since 5 Oct.
Which companies can be charged?
Any company that causes or contributes to the haze in Singapore. This includes:
- Companies that own or occupy the burning land. If satellite or meteorological data show the smoke from those land moved in the direction of Singapore at the time haze occurred in Singapore, the law presumes the landholder to be responsible unless proven otherwise.
- Companies that participate in the management or control of the above companies, such as their parent companies.
How is Singapore connected to the haze?
A 5 Oct 2026 report by Greenpeace and Pantau Gambut found smoke sources in at least 4 Indonesian plantations linked to Singapore-based businesses, including SGX-listed companies. A 14 Oct 2026 report by Walhi Indonesia found 66 companies suspected of causing forest and land fires between January to September 2026 are affiliated with Singapore-based groups.
What are the powers of the Singapore Government under the THPA?
The Singapore Government has the power to:
- Demand information from anyone within or outside of Singapore.
- Order a company to put out fires on its land and stop burning.
- Summon people for questioning.
- Prosecute in court.
What is the penalty?
A fine of up to S$100,000 per day, capped at S$2 million. (This means there will be no additional fines after only 20 days of haze!)
Has the Singapore Government used the THPA before?
After the 2015 haze, the Government investigated 6 Indonesian companies. 2 companies have been cleared but 4 cases remain open to date, 11 years after the initial investigations.
What are our neighbours doing?
NGOs and indigenous groups in Indonesia filed a class-action lawsuit in September, accusing the Indonesian government for gross negligence in handling recurring forest fires and toxic haze.
Environmental and civil groups in Malaysia launched campaigns to urge the Malaysian Government to enact a Clean Air Act, similar to the THPA.
This campaign is co-organised by PM.Haze and SG Climate Rally
