Thailand is one of the 194 signatories of the Montreal Protocol, enforced in Thailand in 1989.
Although the government’s policy of freezing imports of ozone-depleting substances, such as CFCs,
at 1991 levels is working to a certain extent when compared to similar countries, imports and local
consumption of these substances are still very high, more than triple 1989 consumption levels.
Thailand’s domestic users of ozone-depleting substances are the electronics and printed circuit
board industries, refrigerator and air conditioner manufacturers, and a host of other affiliated
sectors, as well as end consumers needing to refill mobile air cooling units.
The Thai government has acknowledged the importance of rapidly reducing the use of CFCs and
has commissioned a country-wide study setting out strategies for a plan of action. However, getting
industry’s compliance is expected to be difficult and will require the government to take a firm stand
through regulation. By virtue of the Notification of the Ministry of Industry Re: Prescribing the
Quantity for Importation of CFC dated 31 December B.E. 2546 (A.D. 2003), the Industrial Works
Department prescribes the quantity for importation of CFC from 2003 to 2010.
Announcement of the National Executive Council No. 16 B.E. 2514 (A.D. 1971) regulates air
pollution caused by motorboats which discharge dangerous smoke. Those convicted of violating the
law are subject to a fine of THB 200. At the discretion of the police, the offending motorboat may be
taken into custody.
The Land Traffic Act B.E. 2522 (A.D. 1979), as amended by the Land Traffic Act No. 8 B.E. 2551
(A.D. 2008), prohibits using automobiles and motorcycles which discharge smoke, dust, or noise
exceeding the prescribed basis. Those convicted of violating the law are subject to a fine of not more
than THB 1,000.
The Land Transport Act B.E. 2522 (A.D. 1979), as amended by the Land Transport Act No. 11 B.E.
2550 (A.D. 2007), determines that vehicles used in transport must be adequately powered and
correctly fitted with equipment and components as prescribed in Ministerial Regulations. Those
convicted of violating the law are subject to a fine of not more than THB 50,000.
The Notice of the Kingdom’s Traffic Officer, issued in 1990 under the authority of the
Announcement of the National Executive Council No. 16 B.E. 2514 (A.D. 1971), prescribes standards
with regard to dangerous smoke and carbon monoxide discharged from automobiles and
motorcycles, while the Notification of the Harbor Department No. 177 B.E. 2527 (A.D. 1984), issued
under the authority of the Announcement of the National Executive Council No. 16 B.E. 2514 (A.D.
1971), prescribes standards with regard to dangerous smoke discharged from motorboats.
New standards and methods for measuring the smoke from automobiles are prescribed under
the Notification of the Ministry of Science, Technology, and Environment dated June 17, 1997,
issued under Section 55 of the Enhancement and Conservation of National Environmental Quality
Act B.E. 2535 (A.D. 1992).Notification of the National Environment Board No. 10 dated April 17, 1995, in addition to
regulating air pollution discharged from motor vehicles, defines standards of air quality. It specifies
maximum standards for various pollutants, such as carbon monoxide, nitrogen dioxide, and sulfur
dioxide. The methods for measuring air quality in the atmosphere are prescribed by the Notification
of the National Environment Board No. 10, the Notification of the Pollution Control Department
dated June 26, 2007, and the Notification of the National Environment Board No. 30 dated
September 14, 2007.
The Factories Act B.E. 2535 (A.D. 1992), including certain regulations and notifications issued
under the 1969 Factories Act, is the principal law controlling air pollution by factories. In addition to
providing penalties for a company operating a factory in violation of stipulated requirements, the
company’s directors, managers, and operators of the factory may also be individually liable for
damages and criminal violations, unless they can prove they did not have knowledge of the acts
related to air pollution.
Although the Enhancement and Conservation of National Environmental Quality Acts of 1975,
1978, and 1979 and the Factories Act of 1969 were technically repealed and replaced by the 1992
Acts, the various ministerial regulations and notifications issued under those earlier Acts (which are
a primary source of environmental controls) were not repealed by the new Acts. The regulations and
notifications continue in full force until specifically repealed by new regulations.
Other laws related to air pollution caused by sources other than motor vehicles and factories are
the Public Health Act B.E. 2535 (A.D. 1992), as amended by the Public Health Act (No. 2) B.E. 2550
(A.D. 2007), which contains general provisions with regard to preserving the environment, together
with the notifications issued thereunder.
Sections 420, 421, and 1337 of the Civil and Commercial Code and Section 396 of the Penal Code
also apply here.
Additionally, in October 1991, under the policy of the Ministry of Industry, a notification was
issued by the Ministry of Industry to reduce air pollution caused by automobiles manufactured in
Thailand as follows:
• From January 1, 1993, gasoline engine automobiles over 1599 cc assembled in Thailand must
have a catalytic converter exhaust emission control system.
• From September 1, 1993, in order for engines to be compatible with the required unleaded
gasoline, every locally assembled automobile, including those under 1600 cc, must possess a
catalytic converter exhaust emission control system.
In relation to industrial emissions, the Department of Industrial Works (DIW), operating under
the Ministry of Industry, is mandated to monitor and enforce standards on industrial operations.
DIW has the authority to revoke a factory’s operating license if the standards set are not being
followed.
Emission guidelines for polluting substances and their effects can be provided by DIW for all
industries.
