Taking copper smelting industry as an example, this paper focuses on the relationship between energy consumption and carbon emission. Firstly, the relevant accounting standards, accounting boundaries and accounting methods of copper smelting energy consumption and carbon emission are sorted out; Secondly, the difference and correlation between copper smelting energy consumption and carbon emission are analyzed. The difference is mainly reflected in the boundary range, such as energy-consumed medium and process emission, and the correlation is mainly reflected in the linear relationship between carbon emission and energy consumption value; Thirdly, based on typical copper smelting process cases and Chinese industry statistical data, the comprehensive energy consumption and carbon emission are estimated, and the near linear correlation between them is verified. The ratio of carbon emission calculated based on national grid emission factor to comprehensive energy consumption calculated by equal value is about 2.0; Finally, suggestions on standard revision are put forward from the aspects of accounting boundary, power conversion coefficient and emission factor value, for reference by the staff of relevant departments.
