JAUE2022-046: Research on Decarbonization based on Carbon Emission Intensity: Case of Xingan Autonomous Prefecture, Inner Mongolian AR, China

Abstract

The carbon emission intensity of land type (land type CEI) is an indicator used in evaluating the carbon emissions of land use plans. Existing studies focus on measuring CEI of major land types without accounting for the whole category of the latest land classification in territorial spatial planning. This study establishes a systematic spatial allocation framework to calculate detailed land use type CEI and proposes a method to assess carbon reduction potential. First, it optimized the correspondence between carbon emission inventory and land types to calculate the CEI. Second, four decarbonization scenarios of "smart growth, low-carbon energy system, green economy, and green infrastructure" were adopted to develop four land use plans. Third, the total carbon emissions of four scenarios were estimated and compared based on land type CEI and the amount of land. This study finds that land type CEI is highly heterogeneous so systematic calculation can effectively improve the accuracy of emissions estimation. Four scenarios have decarbonization potential ranging greatly from 1 to 34% for green infrastructure, smart growth, low-carbon energy system, and green economy. It shows that the future territorial spatial planning in China to achieve "dual carbon goals" should focus more on developing green economy and a low-carbon energy system
