A Study On The Route Of Building Nanjing As Low Carbon City Under The Background Of Climate Change

With the rapid development of China’s economy, the increasing growth of population, and the rising urbanization rate, the particularly prominent industrial structure problems, especially the serious influence on human due to climate change in recent years, which made us pay much more attention to the phenomenon, people gradually realize that something must be done to radically change the mode of production which relies on energy consumption, the economic growth mode at the expense of the environment, and the lifestyle of incontinent consumption. City is the main source of carbon emissions, and the development of low carbon city is considered to be the most desirable economic development power.This paper mainly focuses on the path of Nanjing low carbon city construction. Based on the typical low carbon urban development research on the current situation of Portland, Tokyo, Seattle and Baoding, Wuhan, Wuxi, it provides referential experience for the construction of Nanjing low carbon warning. When analyzing factors which cause CO2emission in Nanjing, population, GDP, per capita GDP, urbanization rate, industrial structure diversity factor (ESD), the energy consumption structure diversity factor (ECSD) and energy intensity are selected as the main index, Nanjing’s total CO2emission is regarded as the reference, and grey relational model is applied to calculate correlation. The result shows that according to the correlation with carbon emissions in Nanjing, the proper order should be ESD, population, urbanization rate, ECSD, energy intensity, per capita GDP, and GDP. This is also in line with the data provided by the research that the carbon emission of energy consumption accounts for68.9%of the total emission of Nanjing and industrial emission for production holds over50%because of the wide use of fossil energy.On the basis of detailed understanding of those factors leading to Nanjing’s carbon emissions, the paper analyzes Nanjing’s CO2emission situation respectively from the following three aspects:Nanjing’s building, transportation, and industry. In the aspect of building, the paper calculates Nanjing’s building carbon emissions, especially power consumption and heat consumption of civil buildings (including residential buildings and public buildings). In the area of transportation, mainly according to the main influential factors of the traffic carbon emissions, the paper calculates the total amount of traffic carbon emissions with the aid of low carbon city’s model and the energy conversion method. In the industrial sector, the energy conversion method and low carbon building model are also used to calculate Nanjing’s industrial carbon emissions. We use situational analysis method at this aspect to predict future carbon emissions targets, and then put forward some countermeasures. In view of the above referential experience at home and abroad and the current situation of Nanjing’s carbon emissions, three paths of the low carbon city construction of Nanjing are described in the paper at these three aspects of building, transportation and industry.
