随着建材工业环境问题的日益严重,人们对其环境信息的需求越来越迫切。如何客观、科学的表达、交流、披露、核查建筑材料的环境影响信息,成为建材工业节能减排的重要命题。Ⅲ型环境声明作为一种有效的环境信息交流工具,其研究在我国建材领域取得了重要进展。根据ISO14025的原则和要求,研究了制定产品生命周期评价技术规范的方法与工作流程。基于此方法,以金属复合装饰板为例,讨论了金属复合装饰板生命周期评价技术规范的制定,展示了金属复合装饰板Ⅲ型环境声明认证示范报告,以期为国内其他产品生命周期评价技术规范制定及III型环境声明认证提供方法基础与示例。
With the increasingly serious environmental problems in the building materials industry, people are more and more desirous of their environmental information needs. How to objectively and scientifically express, exchange, disclose and verify the environmental impact information of building materials has become an important proposition of energy conservation and emission reduction in building materials industry. As an effective environmental information exchange tool, Ⅲ type environmental declaration has made important progress in the field of building materials in our country. According to the principles and requirements of ISO14025, the method and work flow of developing technical specifications for product life cycle assessment are studied. Based on this method, taking the metal composite decorative panel as an example, the paper discusses the formulation of the life cycle evaluation standard of the metal composite decorative panel, and presents the demonstrative report on the certification of type Ⅲ environmental declaration of the metal composite decorative panel so as to provide a reference for other domestic product life cycle assessment technical specifications Formulation and Type III Environmental Declaration Certification provides the basis for the method and examples.
