Abstract：With the increasing prevalence of climate change due to carbon emissions,the international community is paying more attention to carbon reduction.As the world's largest carbon emitter,in the context of the"dual carbon"goal,carbon reduction is becoming more severe.Coal is the main primary energy in China,it is of great practical significance to develop an environmentally friendly society and help China develop sustainably by studying its carbon emission efficiency level and ways of optimizing efficiency.Accordingly,this paper analyzes the consumption status and flow characteristics of coal resources from a multi-dimensional perspective,the key provinces and industries involving coal resources consumption were preliminarily identified.Secondly,based on life cycle theory,the full life cycle of coal resources was divided into four stages,the carbon emission of each stage is constructed,and the carbon dioxide emission of coal resources in different stages is estimated.Finally,based on the research results,practical suggestions are put forward to promote carbon emission reduction of coal resources.In this study,carbon emissions from coal resources throughout the full life cycle are mainly attributed to their conversion and utilization stages,which account for 66.93％and 22.35％respectively.Emissions from the development and transportation stages are relatively small,with the development stage contributing 10.69％and the transportation stage contributing 0.03％.Based on the full life cycle of coal resources,taking the year of 2021 as an example,China's carbon emissions were 8631.69Mt,which was an increase of 88.16％from 2006.
