中欧混凝土产品生命周期评价规则差异研究

Study on Difference of Life Cycle Evaluation Rules of Concrete Products Between China and Europe

标准是为保障产品生命周期环境信息的量化活动规范而制定的基础性支撑文件。文中梳理了中欧建材产品生命周期评价标准体系架构和生命周期的阶段划分,围绕功能单位、参考使用寿命、系统边界、碳化、数据质量要求、取舍类别、环境影响类别等方面,分析了中欧混凝土产品生命周期评价规则之间的差异。

Standards are the basic supporting documents to ensure the standardized development of quantitative activities of product life cycle environmental information.In this paper,the standard system architecture and the stage division of the life cycle evaluation standard system of building materials products in China and Europe are sorted out,and the differences between the life cycle evaluation rules of concrete products in China and Europe are analyzed from the aspects of functional units,reference service life,system boundaries,carbonization,data quality requirements,rejection categories,and environmental impact categories.
