Description | Coal’s green mining and scientific utilization is the key to achieve the national vision of carbon peak by 2030 and carbon neutrality by 2060. Clarifying the $CO_{2}$ flow of coal production is the core part of decarbonization. This study uses an environmental extended multi-regional input–output (EEMRIO) model to analyze the impact of embodied emissions on the indirect $CO_{2}$ emission intensity of coal production between China’s coal mining sector and 141 countries/regions. It is found that the $CO_{2}$ emission intensity of China’s coal production was 34.14 $gCO_{2}$/MJ in 2014, while the direct and indirect emission intensities were 16.22 $gCO_{2}$/MJ and 17.92 $gCO_{2}$/MJ, respectively. From 2007 to 2014, the direct emission intensity of China’s coal production increased by 23%, while the indirect emission intensity decreased by 30%. The key material and service inputs affecting indirect carbon emissions of coal production in China are electricity service, metal manufacturing, chemical products, coal mining, and transport, which accounted for 85.5% of the total indirect emission intensity of coal production in 2014. Globally, a large portion of $CO_{2}$ from Chinese coal production is emitted to meet foreign direct and indirect demands for material and service inputs. Policy implications related to this outcome are further discussed in the study. |
