The aluminium giant also plans to cut its carbon emissions by 40% by 2035, the company said in an action plan released on Tuesday.
China's President Xi Jinping had pledged last year to achieve carbon peak before 2030 and become "carbon neutral" by 2060.
Aluminium production is the biggest contributor of carbon emissions in the nonferrous sector, which accounted for around 6.5% of China's total emissions of the greenhouse gas in 2020.
Major producers in the ferrous industry, including top steelmaking China Baowu Steel Group and HBIS Group had also announced their carbon cut plans this year.
