The State Council issued the “2024-2025 Action Plan for Energy Conservation and Carbon Reduction”, which mentions strengthening the regulation of production capacity and output in the building materials industry. Strictly implement the replacement of cement and flat glass production capacity. Strengthen production monitoring and early warning in the building materials industry, and promote the normalization of erroneous cement production. Encourage comprehensive utilization of tailings, waste stone, waste residue, industrial by-product gypsum, etc. By the end of 2025, the country's cement clinker production capacity will be controlled at around 1.8 billion tons. New construction, renovation and expansion of cement, ceramics, and flat glass projects must meet the energy efficiency benchmark level and environmental performance grade A level. Vigorously develop green building materials and promote the commercialization of basic raw materials, lightweight wall insulation materials, and assembly of decoration materials. By the end of 2025, the cement and ceramics industry will account for 30% of production capacity above the energy efficiency benchmark level, the flat glass industry's share of production capacity above the energy efficiency benchmark level will reach 20%, and production capacity below the energy efficiency benchmark level in the building materials industry has completed technological transformation or phased out.
