In March 2025, Chinese metallurgical enterprises, members of the CISA industry association, increased their total emissions by 9.7% compared to March 2024. This is evidenced by the association's data.
Despite the increase in the indicator, emissions of sulfur dioxide, particulate matter and nitrogen oxides in exhaust gases decreased by 13.1%, 5.5% and 16% YoY, respectively.
Total energy consumption by participating enterprises increased by 2.1% YoY in March. Total energy consumption (electricity, gas, coal, etc.) per ton of steel increased by 0.06% YoY, while comparable consumption decreased by 0.97%. At the same time, electricity consumption per ton of steel increased by 1.3% YoY.
Total electricity consumption increased by 8.4% yoy. Own electricity production increased by 11.7% YoY, and its share in the total balance increased by 1.79 percentage points. The production of clean energy increased by 39.8% YoY, in particular, wind energy – by 327%, and solar energy – by 37%.
Water consumption by the Association's member enterprises decreased by 0.1% yoy. Water intake increased by 2.05% YoY, and the volume of reuse decreased by 1.01%. The water reuse rate fell by 0.05 percentage points to 98.38%. Water consumption per ton of steel increased by 2.2% YoY, to 2.28 cubic meters.
Wastewater emissions decreased by 13.4% YoY. The content of chemical oxygen consumption in water decreased by 10.8% YoY, ammonia – by 12.6%, suspended solids – by 16.3%.
The utilization rate of steelmaking slag, blast furnace slag and iron-containing dust remained above 98%. The use of combustible gases, in particular blast furnace, converter and coke oven gas, exceeded 98%. The share of blast furnace gas use increased by 0.09 percentage points, coke oven gas -by 0.35 percentage points.
