Tracing China’s energy flow and carbon dioxide flow based on Sankey diagrams
Abstract China has promised to optimize its energy structure and reduce its CO2 emission in the 13th Five-Year Plan. To track the energy structure, the conversions, efficiencies, end consumptions of total energy and coal and the whole CO2 emission status, the energy flow, coal flow and CO2 flow in 2015 were, respectively, drawn at the national level based on Sankey diagrams. Besides, each provincial fossil fuel structure, CO2 structure and CO2 intensity were calculated and plotted. It is mainly found that China’s energy structure consisted of 69.2% of coal, 19.9% of oil, 6.3% of natural gas and 4.7% of non-fossil energy, where 45.5% of energy was consumed by industry and 23.9% by losses and statistical difference; coal was distributed to industry (55.6%), etc., with a utilization rate of 70.1%; and CO2 were derived from coal (84.7%), oil (11.1%) and natural gas (4.2%), of which 39.0% was released through the process of thermal power generation and 19.4% by industry. The structures of fossil fuels and their CO2 emissions together with the evolution of CO2 intensity at the provincial level and the regional level were also given. Besides, two pieces of policy implications were proposed to provide the government with reference.
