武安推动钢铁产业绿色转型，蓝天白云铺展崭新画卷

Core Viewpoint - Hebei Province's Wu'an City has transformed its steel industry through significant environmental reforms, achieving ultra-low emissions and improving air quality, leading to the recognition of multiple companies as top-tier in environmental performance [1][2][4]. Group 1: Environmental Performance - Hebei's Jinan Steel Group has implemented a comprehensive ultra-low emission production chain, with real-time monitoring across 1,766 environmental points [1]. - Wu'an City has initiated a "Create A" green revolution, resulting in 16 key industry enterprises achieving A-level environmental performance, representing 84% of the total in the sector [2]. - The highest environmental performance rating, A-level, signifies the best environmental governance in the industry [2]. Group 2: Emission Reduction Initiatives - The city has accelerated the elimination of inefficient production capacities, shutting down 7 small blast furnaces and 9 small converters [2]. - Transitioning from long-process to low-carbon, energy-efficient short-process steelmaking has led to a reduction of 1.6 tons of CO2 and 75% of pollutant emissions per ton of steel produced [2]. - New technology for carbon monoxide catalytic oxidation has been implemented, reducing emissions from approximately 4,200 mg/m³ to about 1,500 mg/m³ [3]. Group 3: Air Quality Improvement - In 2024, Wu'an's average carbon monoxide concentration was 2.1 mg/m³, a 12.5% decrease year-on-year [4]. - PM2.5 concentration in the first half of 2025 was recorded at 37.2 µg/m³, a 31.27% decrease compared to the previous year, with 133 days classified as good air quality [4]. - The transformation has led to a harmonious coexistence of industrial and ecological environments, enhancing the quality of life for residents [4].
