Carbon Balance in Nanjing's Ecological Economic System

Abstract:

Along with new urbanization, substantial debates have been triggered on whether urban ecological economic system of CO₂ balance relates to the sustainable urbanization. Based on the data of Nanjing city, China, in 2010, we calculate the total amount of CO₂ emission and CO₂ sequestration. Results show that CO₂ emission mainly comes from industrial production (63.19%) and transportation (33.44%). Moreover, industrial raw coal (51.69%) is the main source of the carbon emission, whereas cultivated land (68.62%) and forestland (27.59%) are the most important carriers of CO₂ sequestration. According to the calibrated results, we conclude that: (1) The relationship between the urban ecological subsystem and economic subsystem is uncoordinated; (2) Nanjing's economic development exerts particular influences on other regions ecological environment.
