The challenge faced by Indonesia is private rights of intellectual property holder affecting barriers for mass production. This article looks for justification for Indonesia’s adoption of transfer of green technology for protection of public health regarding the WTO rule and international conventions concerning on climate change. It uses qualitative methodology with legal-descriptive and normative approach applied. The rule of WTO and international conventions on climate change instruments become primary sources to appraise the justification of the measures.

Article 31 of TRIPs Agreement regulates that compulsory licensing might be imposed for adoption of technology transfer in circumstances for protection of public health. It could be extensively interpreted that air pollution may threaten health of human being as Doha Declaration 2001 justify flexibility application of compulsory licensing.
