Research on Urban Carbon Emission Inventory and Its Application in Planning

This paper systematically reviewed related studies on urban carbon emission inventory, and especially analyzed current studies on the urban greenhouse gas inventory in China. Through comparative studies of four cases, it systematically discusses the application of urban carbon emission inventory in low carbon urban planning as a response to climate change, it thus concluded that city planners in China have duty-bound obligations and responsibilities to apply low carbon ideas into urban and regional planning, and the in-depth study on greenhouse gas emission inventory is undoubtedly of great significance and scientific value to mitigate climate change.

Study on carbon emission in prefecture-level cities of china

The study on greenhouse gas inventory in urban China lags far behind the global level. The important factor that curbs the carbon inventory of cities of China is inventory methodology and scope. Given the insufficiency of Chinese cities carbon inventory, a system and accounting model （scopel＋ scope2） as well as principles and boundaries were proposed for China. The carbon emissions in scopel and scopel＋ scope2 were calculated in Chinese prefecture-level cities. The EDGAR dataset was used for the calculation of scopel carbon emissions in cities in China and the level of uncertainty was analyzed as well. The results showed that the direct carbon emission of cities in China was about 31.65% of China total emissions. The scopel＋ scope2 carbon emissions in cities of China were calculated based on the GIS and RS model. The results showed that the sum of direct （scopel） and indirect （scope2） carbon emissions of cities in China accounted for 38.80% of total China carbon emissions.

Development of a stationary ca,-bon emission inventory for Shanghai using pollution source census data

This study utilizes 521,631 activity data points from the 2007 Shanghai Pollution Source Census to compile a stationary carbon emission inventory for Shanghai. The inventory generated from our dataset shows that a large portion of Shanghai＇s total energy use consists of coal-oriented energy consumption. The elec- tricity and heat production industries, iron and steel mills, and the petroleum refining industry are the main carbon emitters. In addition, most of these industries are located in Baoshan District, which is Shanghai＇s largest contributor of carbon emissions. Policy makers can use the enterprise- level carbon emission inventory and the method designed in this study to construct sound carbon emission reduction policies. The carbon trading scheme to be established in Shanghai based on the developed carbon inventory is also introduced in this paper with the aim of promoting the monitoring, reporting and verification of carbon trading. Moreover, we believe that it might be useful to consider the participation of industries, such as those for food processing, beverage, and tobacco, in Shanghai＇s carbon trading scheme. Based on the results contained herein, we recommend establishing a comprehensive carbon emission inventory by inputting data from the pollution source census used in this study.

多层次城市国土空间碳排放分配与评估框架——以兴安盟为例

It is proven a powerful tool to reduce carbon emissions by regulating urban land use structure.To leverage this tool,land-use carbon emission intensity(LUCEI)is the critical indicator to bridge carbon emissions effects of natural and human activities to land use structure.Current studies try to established the carbon emission allocation framework of“carbon emission inventory–land use category”and use it to estimate the LUCEI.However,none of the frameworks work at multiple spatial scales:the total carbon emissions and the land use category at different territorial levels do not conform with each other,impeding the synergetic effects of the low-carbon planning at different territorial levels.This study establishes a new framework of carbon emission estimation and allocation for the three territorial levels of municipality,city proper,and district and conducts a case study on Hinggan Prefecture.With the new framework,the carbon emission intensity of the entire land use category is being systematically differentiated,enabling the clarification of the linkages between LUCEI and the characteristics of energy structure,industrial structure,and urban forms of cities.The comparison of LUCEI of residential and transportation land between cities identifies the characteristics of urban form that are apt to high carbon emissions.The biggest contribution of the framework established in this study provides a technical tool to introduce carbon emission quantifi-cation into the territorial and spatial planning system.It may help deepen the understanding about the spatial pattern of carbon emissions and support a more refined estimation and comparison of the carbon effects of land use planning schemes.
