LMDI Decomposition of Energy-Related CO2 Emissions Based on Energy and CO2 Allocation Sankey Diagrams: The Method and an Application to China

“…K PEQ , the primary energy quantity conversion factor, which was suggested by authors in previous studies [7,18,19,26], is a key parameter for establishing the connection between energy consumption of end-use sectors and primary energy consumption. K PEQ is defined as the total number of units of primary energy that are consumed to produce one unit of secondary energy.…”

“…This will indicate the responsibility of each sector in various stages for total CO 2 emissions. The 13 energy types in the mapping are defined in Table A3 and described in previous studies [7,18,19]. To illustrate the structure of the final energy consumption and CO 2 emissions of each subsector in the diagram, we re-categorized the subsectors as shown in Table A4.…”

“…Based on our previous works on energy allocation Sankey diagrams [7,18,19], we can acquire the K PEQ of each secondary energy to establish the connection between end-use energy consumption and primary energy consumption. Additionally, we can further derive corresponding parameters by emission factors to establish the connection between end-use energy consumption and CO 2 emissions.…”

“…To solve it, Chong et al [18] presented a programmed data-processing method for mapping energy allocation Sankey diagram and introduced primary energy quantity converted factor (K PEQ ) to connect end-use energy consumption and primary energy consumption. After that, Chong et al [19] further introduced an input-output approach to acquire K PEQ and generate the data for mapping an energy allocation Sankey diagram. Based on those works and others, Soundararajan et al [20] provided a review of energy allocation Sankey diagrams and suggested a framework to use it for national level analysis.…”

“…However, the compensating process for the energy losses upstream is complex and involves many interacting conversion sub-sectors. Thus, the authors further introduced an input-output method to acquire the K PEQ of each energy type in a prior study [19].…”
