Understanding Climate Mitigation Responses in the United States and China from Strategic and Institutional Perspectives

The United States and China have common but differentiated climate mitigation responses. Most studies so far have sought to explain this divergence with a focus on energy resources, technology, economic, or social factors. These studies ignore the role of strategy and institutions, and thus appear incomplete. In this paper, the author investigates the climate mitigation responses of the United States and China from a strategic and institutional perspective, explores how their climate responses are shaped, and identifies possible weaknesses hidden in their climate approaches. The paper finds that the United States and China have distinct national climate positions due to their diverse strategies and institutions. However, they have chosen similar policy tools and have achieved fairly comparable emission reductions thus far. In the long run, the effectiveness and efficiency of the low-carbon transformation will possibly be hindered by weaker policy innovation capability at sub-national levels in China and the operationally volatile energy strategy in the United States.
