Bo QIN, Jianfeng WU, China Economic Review, Does urban concentration mitigate CO2 emissions? Evidence from China 1998–2008

Abstract: This paper provides evidence of first increasing and then decreasing CO2 emission intensity as the degree of urban concentration increases, based on data from 25 provincial regions in China over the period 1998–2008. This evidence is consistent with the environmentally desirable urban concentration argument identified in recent literature. Our findings indicate the importance of the spatial organization of activities and people in addressing regional CO2 emissions.
