In May 2026, the China Association of Building Energy Efficiency released two official standards: Assessment Standard for Near-Zero Energy Prefabricated Steel Structure Buildings (T/CABEE 133-2026) and Assessment Standard for Zero-Carbon Prefabricated Steel Structure Buildings (T/CABEE 134-2026), both effective July 1, 2026. This establishes unified quantifiable evaluation criteria for the low-carbon performance of steel buildings.
Formalized steel structure carbon emission calculation standards rolled out in May 2026, enabling measurable, tradable and monetizable carbon advantages. With over 90% steel recyclability, manufacturers equipped with carbon footprint auditing capabilities gain competitive edges in green building certification, government procurement and EU export markets. As the EU Carbon Border Adjustment Mechanism (CBAM) advances, steel structure product exports to Europe require complete carbon footprint documentation.
Steel structures hold natural advantages for green building ratings: high material recyclability, shortened construction cycles and minimal on-site wet operations. The integrated main frame-slab-enclosure PK system developed by Wanstar reduces carbon emissions per square meter by roughly 15% via optimized material dosage and structural detailing. Light steel structure products manufactured with low-carbon processes (cold roll forming, chrome-free passivation) will dominate future market demand, and carbon footprint accounting has shifted from an optional bonus to a mandatory market entry threshold.
