1.范围1。1本标准建立了评估加拿大纸浆和纸张生命周期生产阶段潜在环境影响的评估方法。该方法旨在用于内部评估，以指导环境绩效的改善。1.2这些建议和要求旨在帮助最终用户（如工厂经理或其员工）确定污染预防和资源节约的机会。本标准（a）为纸浆和纸张生产阶段（LCIA-PPPP）的生命周期影响评估建立了通用框架；（b） 定义进行LCIA-PPPP的系统边界；（c） 描述影响评估中包含的压力源和相关指标； （d） 描述与所选ed应激源相关的潜在影响链；（e） 提出了一种用于压力源和度量评估的数据清册方法；（f） 为评估结果提供指导；和（g）使最终用户能够传达纸浆和造纸厂随着时间的推移在环境性能方面的相对改善。1.3 LCIA-PPPP方法侧重于“影响评估”，即生命周期评估（LCA）四个阶段中的一个阶段，以及纸浆和纸张生命周期四个阶段中的一个阶段。该方法不用于与其他工厂的外部比较，也不用于产品营销目的。其目的是在工厂内作为决策工具。注:尽管LCIA的应用有限，但是- PPPP方法，影响评估结果可用于本标准范围内所述以外的目的。附录B列出了此类情况下应考虑的道德因素。1.4本标准描述了目标和范围定义，以及收集LCIA-PPPP所需库存数据的方法。然而，正如CSA标准Z760和CAN/CSA-ISO 14040所述，这些并不是为了取代LCA的启动和库存阶段。本标准应与适用于产品生命周期所有阶段的分析和改进工具结合使用。

1. Scope1.1This Standard establishes an assessment methodology for the evaluation of potential environmental impacts of the production phase of the pulp and paper life cycle in Canada. The methodology is intended to be used for internal evaluations, so as to guide improvement in environmental performance.1.2The recommendations and requirements are intended to help end users (eg, mill managers or their staff) identify opportunities for pollution prevention and resource conservation. This Standard (a) establishes a common framework for conducting a life cycle impact assessment of the pulp and paper production phase (LCIA-PPPP); (b) defines system boundaries for conducting a LCIA-PPPP; (c) describes the stressors and associated metrics to be included in the impact assessment; (d) describes the potential impact chains associated with the select ed stressors; (e) presents a data inventory method for stressor and metric evaluation; (f) provides direction on the valuation of the results; and (g) enables the end user to communicate the pulp and paper mill's re lative improvement in environmental performance over time.1.3The LCIA-PPPP method focuses on ""impact assessment"", only one of four phases of life cycle assessment (LCA), and on only one of four stages in the pulp and paper life cycle. The methodology is not intended to be used for external comparisons to other mills, or for product marketing purposes. It is intended to serve within the mill as a decision-making tool. Note: It is recognized that, despite the limited applications of the LCIA-PPPP methodology, impact assessment results may be used for purposes other than those described within the Scope of this Standard. Appendix B sets out the ethical considerations that should be addressed in such cases.1.4This Standard describes goal and scope definition, as well as a method for collecting the inventory data required to conduct a LCIA-PPPP. However, these are not intended to replace the initiation and inventory phases of LCA, as described in CSA Standards Z760 and CAN/CSA-ISO 14040. This Standard should be used in conjunction with analysis and improvement tools that apply to all stages of the product life cycle.
