Japan’s Policy on Net Carbon Neutrality by 2050

Abstract

Japan eventually joined the 2050 net carbon neutrality club soon after the Suga administration emerged. What are the primary drivers of Japan’s decision and why this timing? This article argues that the interactions of domestic and international factors can explain this policy change in the context of global competition over energy transition and technological breakthroughs to mitigate climate change. Japanese Prime Minister Yoshihide Suga’s move was almost an established policy line brewed during the predecessor government.
