ASEAN Agreement on Transboundary Haze Pollution
The ASEAN Agreement on Transboundary Haze Pollution is an environmental agreement established in 2002 between all ASEAN nations to reduce haze pollution in Southeast Asia  The Agreement recognises that transboundary haze pollution which result from land and/or forest fires should be mitigated through concerted national efforts and international cooperation.
The agreement is a reaction to an environmental crisis that hit Southeast Asia in the late 1990s. The crisis was mainly caused by land clearing via open burning in the Indonesian island of Sumatra. Satellite images confirmed the presence of hot spots throughout Borneo, Sumatra, the Malay Peninsula and several other places. Malaysia, Singapore and to a certain extent, Thailand and Brunei were particularly badly affected.
From Sumatra in Indonesia, monsoon winds blew the smoke eastward, creating negative environmental effects (externalities) on other Southeast Asian nations. Thick haze covered much of Southeast Asia for weeks and caused noticeable and widespread human health problems.
As of June 2013, all the ASEAN countries, except Indonesia, have ratified the agreement.
However Indonesia hopes to ratify the haze agreement by 2015.
