• 摘要：根据生命周期的理论框架及Ⅲ型环境声明的要求,对我国新闻纸产品系统的资源能源消耗及环境排放进行了定量分析和评估.研究系统边界从制浆废纸原料的收集到新闻纸产品运输至用户,主要单元过程包括制浆、抄纸、主要化学品生产、能源生产、运输等.通过评价分析最终得到以1000 kg新闻纸为功能单位的生命周期清单结果,同时定量评估了其对全球变暖、酸化、富营养化、光化学烟雾4种环境影响类别的影响潜值,分别为1679.94 kg(以CO₂当量计)、12.33 kg(以SO₂当量计)、13.30 kg(以NO^-₃当量计)、0.59 kg(以C₂H₄当量计).在此基础上,制定了新闻纸Ⅲ型环境声明的产品种类规则(PCR)和环境产品声明(EPD)文件,在我国首次建立了新闻纸Ⅲ型环境声明的实施框架,为我国Ⅲ型环境声明的进一步实施与推广奠定了基础.

• Abstract：According to the theory and framework of life cycle assessment (LCA) and the requirement of type Ⅲ environmental declarations (type Ⅲ ED), resource and energy consumption and the environmental emission of the newsprint produced in China were quantitatively evaluated. The system considered in this work includes the unit processes of pulp production, paper production, main chemical production, energy production, and transportation of the waste paper and newsprint. The inventory and the impact assessment results were obtained for a functional unit of 1000 kg newsprint. The four environmental impact categories were GWP 1679.94 kg(CO₂-eq), AP 12.33 kg(SO₂-eq), NP 13.30 kg(NO^-₃-eq), POPC 0.59 kg(C₂H₄-eq). Based on the research findings, the product category rules (PCR) and the environmental product declaration (EPD) of the newsprint were constructed and for the first time the implementation framework of type Ⅲ ED was established. This study will provide technical support in developing and popularizing type Ⅲ ED in China.

• Key words：newsprint  life cycle assessment  type Ⅲ environmental declaration  product category rules  environmental product declaration
