Abstract: It is nothing new that governments advance self interested policies during international policy negotiations and that the knowledge of policy experts reflects frameworks which are weaved into international policies. But it is unclear though if policy makers take deliberate steps to eliminate potential ineffective models when crafting international regulatory instruments. Using the Convention on Biological Diversity (CBD) as a focus, this paper examines how an environmental regime\'s policies can build on sustainable institutional systems, enhance sustainable policy frameworks, save scarce resources, improve informed & effective community participation, and legitimise policy objectives. By examining whether multidisciplinary approach and knowledge can enhance the achievement of policy goals, as well as expose possible setbacks to achieving effective regime policies, this paper espouses multidisciplinary tools for understanding regime policy. It highlights potential topics for contemporary policy debates and themes for further research in the field of policy making. It is argued that debates about policy discourses in the 21^st century ought to concern the degree of policy effectiveness: not policy ineffectiveness per se.
