1.1 本指南为制定制造商特定程序以评估制造过程的环境可持续性绩效提供了指导。本指南介绍了可用于提高可持续性绩效的决策支持方法。 1.2 本指南的范围受到生命周期制造阶段的限制。该指南阐述了与该阶段内的流程和程序相关的细节。 1.3 本指南将允许制造商在工厂和企业生产过程中进行有效评估- 制造阶段的广泛决策。 1.4 本指南侧重于环境可持续性影响，但并未明确排除社会和经济影响。 1.5 本指南涉及: 1.5.1 为一个或多个过程的环境可持续性评估设定界限， 1.5.2 确定环境可持续性驱动过程评估所需的过程和设备相关参数， 1.5.3 使用这些参数创建过程模型， 1.5.4 利用过程模型支持一致的评估和可持续性- 制造企业中的驱动决策。 注1: 有关企业级决策的更多指导，请参阅ULE 880。 1.6 本指南可用于补充其他涉及可持续性和产品生命周期的标准。本指南与ISO 14040系列（ISO 14040，ISO 14044）标准中讨论的库存组件、ISO 50000系列（ISO 50001）标准中讨论的效率以及ISO 55000系列（ISO 55001）标准中讨论的资源管理密切相关。 1.7 以国际单位制表示的数值应视为标准值。 本标准不包括其他计量单位。 1.8 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.9 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本指南为制造界评估制造过程的环境可持续性方面提供了参考。本指南旨在通过提供一致的制造过程评估程序来提高非正式方法的效率和一致性。 4.2 本指南描述了识别参数和模型的程序，用于评估特定过程的可持续性指标。本指南的用户将受益于对选定过程的可持续性影响以及促成因素的深入了解。

1.1 This guide provides guidance to develop manufacturer-specific procedures for evaluating the environmental sustainability performance of manufacturing processes. This guide introduces decision support methods that can be used to improve sustainability performance. 1.2 The scope of this guide is constrained by the manufacturing phase of the life cycle. The guide addresses specifics related to the processes and procedures within this phase. 1.3 This guide will allow manufacturers to make effective evaluations during plant and enterprise-wide decision-making within the manufacturing phase. 1.4 This guide focuses on environmental sustainability impacts, though social and economic impacts are not explicitly excluded. 1.5 This guide addresses: 1.5.1 Setting boundaries for the evaluation of environmental sustainability of a process or processes, 1.5.2 Identifying the process and equipment-related parameters necessary for environmental sustainability-driven process evaluation, 1.5.3 Creating process models using these parameters, 1.5.4 Utilizing process models to support consistent evaluations and sustainability-driven decision-making in a manufacturing enterprise. Note 1: See ULE 880 for additional guidance at enterprise-level decision-making. 1.6 This guide may be used to complement other standards that address sustainability and the product life cycle. This guide most closely relates to the inventory component as discussed in the ISO 14040 series (ISO 14040, ISO 14044) standards, efficiency as discussed in the ISO 50000 series (ISO 50001) standards, and resource management as discussed in the ISO 55000 series (ISO 55001) standards. 1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This guide provides a reference to the manufacturing community for the evaluation of environmental sustainability aspects of manufacturing processes. This guide is intended to improve efficiencies and consistencies of informal methods by providing procedures for consistent evaluations of manufacturing processes. 4.2 This guide describes a procedure to identify parameters and models for evaluating sustainability metrics for a particular process. Users of this guide will benefit from insight into the sustainability implications of selected processes as well as the contributing factors.
