In December 2025, Chinese steel enterprises belonging to the CISA industry association increased their total emissions by 4.41% compared to December 2024. This is evidenced by data from the association.

Despite the increase, emissions of sulfur dioxide, particulate matter, and nitrogen oxides in waste gases decreased by 16.74%, 3.65%, and 19.35% year-on-year, respectively.

Total energy consumption by participating companies in December decreased by 6.4% y/y. Total energy consumption per ton of steel increased by 4.4% y/y, and comparable consumption increased by 2.5% y/y. Electricity consumption per ton of steel increased by 6.2% y/y.

Total electricity consumption decreased by 0.5% y/y. Own electricity production decreased by 1.4% y/y, and its share in the total balance decreased by 0.57 p.p. to 58.95%. Clean energy production increased by 46.9% y/y, including wind energy by 415.1% and solar energy by 42.2%.

Water consumption by member companies increased by 3.6% y/y. Water withdrawal decreased by 1.5% y/y, while reuse increased by 3.6%. The water reuse rate increased to 98.49% (+0.08 p.p.). Water consumption per ton of steel increased by 10.1% y-o-y – to 2.55 cubic meters. Wastewater emissions increased by 1.7% y-o-y.

The utilization rate of steelmaking and blast furnace slag, as well as iron-bearing dust, remained above 99%. The use of combustible gases, in particular blast furnace, converter, and coke oven gases, exceeded 98%, and converter gas extraction increased by 1.7% y/y.

It should be noted that in 2024, total emissions in China’s steel industry

increased

by 4.1% compared to 2023. The increase in the liquidity of blast furnace capacities compared to electric arc furnaces increased emissions in the industry despite a decline in annual steel production.

The South East Asia Iron and Steel Institute (SEAISI) was incorporated in 1971 under the auspices of the United Nations Economic Commission for Asia and the Far East (ECAFE). It is registered as a limited company in the Republic of Singapore. Previously in Singapore and the Manila, the Secretariat is now permanently based in Shah Alam, Malaysia.

SEAISI is a technical institute and its main objective is to promote the iron and steel industry in the South East Asia region. It achieves its objectives by facilitating technology transfer from around the world, especially from Japan, Korea and Taiwan. SEAISI organizes a major international conference and exhibition every year and amongst its publications are the Statistical Year Book and the Monthly ASEAN Iron & Steel Journal.

SEAISI enjoys a large membership base with members coming from all parts of the world, including leading steel companies and material suppliers and equipment suppliers.
