The transboundary nature of environmental issues and formation of gradual common knowledge about urgency of the threats from environmental degradation have led countries to set up various regimes- especially those regimes articulated in multilateral environmental agreements— for environmental issues over the last decades. Despite this, the effectiveness of these governance systems has not been successful in practice in terms of compliance or problem except in a few cases. This study sets out to investigate why states cooperation has faced many challenges in practice despite of international community common knowledge about the threats posed by environmental degradation. The authors argue that countries have a different Situation definition of the status of environmental threats in the international system. This perception has led them to have different internalization of environmental values and norms. This has ultimately weakened the effectiveness of environmental regimes. The research method is based on counterfactual conditionals. The results show that by changing the perceptions and understanding of the nature and environment, as well as by implementing reforms in the mechanisms and processes of decision-making system, it is possible to improve the efficiency of environmental regimes.
