Local officials are often viewed as relatively weak actors in China’s governance structure, largely implementing policies issued from the central level. However, a new book – “Implementing a low-carbon future: climate leadership in Chinese cities” – argues that these officials play an important role in designing innovative and enduring climate policy. The book follows how four cities – Shenzhen, Zhenjiang, Xiamen and Nanchang – approached developing low-carbon policies over the course of almost a decade. It identifies “bridge leaders” – mid-level local bureaucrats who have a strong interest in a specific policy area and who are unlikely to move often between different posts – as key to effective local climate policymaking. Carbon Brief interviews author Weila Gong, non-resident scholar at the UC San Diego School of Global Policy and Strategy’s 21st Century China Center and visiting scholar at UC Davis, on her research. The interview has been edited for length and clarity. Gong on why cities are important: “Over 85% of China’s carbon emissions come from cities. The majority of Chinese people live in cities, so the extent to which cities can become truly low-carbon will also influence China’s climate success.” On what motivates local policymakers: “Mid-level bureaucrats need to think about how to create unique, innovative and visible policy actions to help draw attention to their region and their bosses.” On cities as a way to test new policies: “Part of the function of local governments in China is to experiment with policy at a local level, thereby helping…
