摘要
Chinaneeds to reduce its carbon emissions if global climate change mitigation is to succeed. Conventional economic analysis views cutting emissions as a cost, creating a collective action problem. However, decarbonization can improve productivity andprovide co-benefits that accord with multiple national policy objectives. We track China ＇ s progress in reducing the emissions intensity of the economy, and construct a macro scenario with China＇s carbon emissions peaking in the 2020s. Investment in greater energy productivity and economic restructuring away from heavy industries can bring productivity gains, and decarbonization of energy supply has important co-benefits for airpollution and energy security. Combined with lower climate change risks and the likelihood thai China＇s actions will influence other countries, this suggests that cutting carbon emissions is not only in China＇s self-interest but also in the global interest. To properly identify the true costs and benefits of climate change action requires new thinking in economic analysis.
