Abstract:

Since 2011, the construction of China’s carbon emission trading market has been accelerated, and the carbon emission trading mechanism has been continuously improved. The benchmark method has been determined as the main method of national carbon trading initial allowance allocation method. The electrolytic aluminum sector is a key sector in China’s energy consumption and carbon emissions. Incorporating electrolytic aluminum sector into carbon market as soon as possible is of great significance to the industry’s emission reduction, the in-depth promotion of national carbon market transactions, and the response to the challenge of international carbon tariffs. Based on the carbon emissions related data that directly reported by the electrolytic aluminum sector in 2018, this paper presents a benchmark plan for China’s electrolytic aluminum sector to carry out national carbon trading. The results show that the electrolytic aluminum sector should select 8.12-8.15 t CO₂ per t aluminum as the benchmark value, and there is no need to set the regional difference adjustment coefficient. At the same time, in order to ensure the smooth development of carbon trading in the electrolytic aluminum sector, it is necessary to determine the industry quota plan as soon as possible, further improve the monitoring, reporting and verification of corporate emissions to improve the quality of direct reporting data, and further study the scope of carbon emissions accounting for the electrolytic aluminum industry.
