Toward a Model of International Environmental Action: A Case Study of Japan's Environmental Conversion and Participation in the Climate Change Environmental Regime

This article explains the empirical puzzle of Japan's green conversion from an environmental pariah to a leading player in the climate change environmental regime. My argument is that Japan pursued environmental action to reconstruct its international image and demonstrate itself to be a responsible global actor. Claiming that existing explanations fall short, I delineate an international environmental action model that incorporates a more comprehensive cost–benefit framework examining both real and ideational factors. To test the model, I examine four key episodes of Japan's participation in the climate change environmental regime. The empirical analysis reveals the relevancy of the environmental action model, as all four episodes are either fully or partially explained by the model's mechanisms. Finally, I provide some conclusions, suggest that this model fills in the gap in the literature on environmental foreign policy, and provide topics for future research.
