China's electrolytic aluminum production has maintained unsaturated production capacity all year round. With the introduction of the "carbon neutrality" policy, China's electrolytic aluminum production capacity has gradually reached the policy ceiling of 45 million tons, and the smelting energy structure continues to shift to clean energy.

The electrolytic aluminum industry is a high-energy-consuming industry. Electrolytic aluminum production accounts for about 6% of the country's coal consumption, second only to the steel and cement industries. The production of one ton of electrolytic aluminum in the electrolytic link emits 1.8 tons of carbon dioxide. The consumption of one ton of electrolytic aluminum in thermal power generation 4.32 tons of coal, emitting 11.2 tons of carbon dioxide. The electricity used in the electrolytic aluminum industry is generally divided into self-supplied power and outlets.

Self-supplied electricity accounts for about 65%, all of which are thermal power generation; grid power accounts for about 35%, of which thermal power generation accounts for 21%. %, clean energy (such as hydropower, wind power) accounts for 14%. Electrolytic aluminum production energy relies on coal power. In the future, renewable energy may become the mainstream of the market. The application of recycled aluminum is also being implemented on a pilot basis. The carbon emissions of recycled aluminum are only 2.1% times that of electrolytic aluminum.
