Carbon Footprint Assessment and Analysis on Driving Factor in North China from the Perspective of Spatial and Temporal Heterogeneity
The carbon footprint is an important indicator of carbon emissions,and reducing the carbon footprint is a prerequisite for achieving the"dual carbon goal".As a region with high energy consumption and emissions in China,it is of great significance to objectively quantify the carbon footprint and explore the main driving factors to accelerate carbon emission reduction in North China.This study aims to calculates the carbon footprint of North China from the"Tenth Five-Year Plan"to the"Thirteenth Five-Year Plan"using the IPCC method.It employs standard deviation ellipse analysis to examine the distribution and transfer characteristics of the carbon footprint,and applies geographic detectors to identify the main driving factors behind it.The study found that:(1)The total carbon footprint during the"Tenth Five-Year Plan"to the"Thirteenth Five-Year Plan"went through two stages of"first increase-then decrease",rising from 4 254.52 million tons during the"Tenth Five-Year Plan"to 10 663.53 million tons,and then gradually decreasing to 8 989.08 million tons during the"Thirteenth Five-Year Plan".(2)The standard deviation ellipse shows a stable"south-north"distribution,with the center of gravity distributed between Shanxi Datong and Hebei Zhangjiakou,showing a trend of northwest deviation,which has deviated by 72.56 kilometers.(3)Energy intensity,industrial structure,and urbanization rate have a greater explanatory power for driving factors of the carbon footprint,and key interaction factors all involve energy intensity,industrial structure,and R&D investment.There are spatiotemporal differences in the distribution of carbon footprints and influencing factors in North China at different times,and the spatiotemporal heterogeneity of regional carbon footprints should be fully considered when formulating carbon reduction policies.
