Moreover, the existence of interest approach would lead for international environmental collaborations by promoting the principle of transboundary liability, subsequently influence in the early negotiations of creating MEAs, which include the Montreal Protocol. The Montreal Protocol has managed to seek international environmental collaboration among almost all of the nations in the world, which made the Montreal Protocol become a successful one. Therefore, the primary purpose of this study is to explain the influence of interest approach that promotes the principle of transboundary liability in the international environmental governance and law on regards of the Montreal Protocol’s early negotiations and the relations of the interstates participation response. Meanwhile, the methods of this study are based on qualitative set up, which is based on the meetings’ proceeding reports of the Montreal Protocol. Finally, the results potentially provide with better understanding of the influence of interest approach in promoting the principle of transboundary liability in order to lead for further development and expansion of the rules on international environmental governance and law for achieving the global environmental protection goals.
