环境管理.产品体系的生态效益评估.原则,要求和指南

[中文适用范围]： 本标准描述了产品系统生态效率评估的原则、要求和指南，包括： a) 生态效率评估的目标和范围定义； b) 环境评价； c) 产品系统价值评估； d) 生态效率的量化； e) 解释（包括质量保证）； f) 报告； g) 对生态效率评估进行严格审查。 不包括对环境影响和价值类别的具体选择的要求、建议和指南。 在目标和范围定义阶段考虑了生态效率评估的预期应用，但结果的实际使用超出了本国际标准的范围。 [外文原描述]： ISO 14045:2012 describes the principles, requirements and guidelines for eco-efficiency assessment for product systems including: the goal and scope definition of the eco-efficiency assessment; the environmental assessment; the product-system-value assessment; the quantification of eco-efficiency; interpretation (including quality assurance); reporting; critical review of the eco-efficiency assessment. Requirements, recommendations and guidelines for specific choices of categories of environmental impact and values are not included. The intended application of the eco-efficiency assessment is considered during the goal and scope definition phase, but the actual use of the results is outside the scope of ISO 14045:2012.
