1.1 这一标准做法提供了一种基于科学的方法，用于评估涉及生物质能源或化学品的备选方案的相对可持续性。选项可能涉及产品、流程或项目。 1.2 该方法包括设定目标和目的，确定利益相关者，选择适当的指标，以及在至少有一种选择可以从生物质中获得的情况下评估选择的相对可持续性。 1.3 目标是促进公平比较各种选择，将工作重点放在反映利益攸关方优先事项的实际指标上，并支持持续改进，以取得更可持续的成果。 1.4 本标准实践的目的不是宣布某些东西是可持续的或不可持续的，而是帮助用户根据特定的目标和目的对选项进行评估、比较和排名。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This standard practice provides a science-based methodology for evaluating the relative sustainability of options involving energy or chemicals derived from biomass. Options may involve products, processes, or projects. 1.2 The methodology includes setting goals and objectives, identifying stakeholders, selecting appropriate indicators, and evaluating the relative sustainability of options where at least one option is available from biomass. 1.3 The objectives are to facilitate fair comparison of options, focus efforts on practical indicators reflecting stakeholder priorities, and support continual improvement for more sustainable outcomes. 1.4 The purpose of this standard practice is not to declare something as sustainable or not sustainable but to help users assess, compare, and rank options based on specific goals and objectives. 1.5 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. 1.6 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.
