摘要：Surface decorative materials enhance the aesthetics and diversity of wood products, promote the comprehensive use of forest resources, and preserve biodiversity. With increasing global demand for sustainable development, the environmental performance of surface decorative materials in wood products has received significant attention. However, research in this field remains limited. This study innovatively integrates life cycle assessment (LCA) with corporate carbon performance evaluation of surface decorative materials in wood products. A gate-to-gate LCA model was developed to analyze four types of surface decorative materials: printed paper, impregnated paper, high-pressure decorative laminates (HPL), and polyvinyl chloride (PVC) decorative film. The model comprehensively compares the environmental performance of these materials across 13 midpoint environmental indicators and one comprehensive indicator for energy consumption and emission reduction (ECER). The results reveal that the HPL production process has the greatest environmental impact, followed by PVC decorative film, impregnated paper, and printed paper, which exhibits the least environmental impact. Specifically, the ECER values for HPL are 1.27 times, 1.49 times, and 3.64 times those for PVC decorative film, impregnated paper, and printed paper, respectively. The different production processes for these materials lead to variations in energy consumption, which contributes to their varying environmental performance. Different energy sources exhibit varying sensitivities to specific materials and environmental indicators. However, electricity, natural gas, and steam are the main environmental hotspots in the production of surface decorative materials. The carbon performance assessment reveals that the enterprise has total annual carbon emissions of 9,642.84 t CO2e, with a carbon emission intensity of 14.46 t CO2e per million yuan of production value. This intensity is significantly lower than the industry average, indicating that the enterprise has relatively strong carbon performance. These findings provide new insights into the environmental performance of surface decorative materials in wood products and the carbon performance of their manufacturers.
