本文件规定了基于ISO 14067并符合国际生命周期评估标准（ISO 14040和ISO 14044）的生物塑料产品部分碳足迹的生物塑料工艺碳足迹（见ISO 22526-1）的量化和报告要求和指南。 本文件适用于塑料材料的工艺碳足迹研究（P-CFP），即产品的部分碳足迹，无论结果是否公开。 本文件提供了产品部分碳足迹（部分CFP）量化的要求和指南。根据ISO 14067，使用本文件中规定的特定条件和要求，将工艺碳足迹研究作为部分碳足迹进行。 如果根据本文件报告P-CFP研究的结果，则提供程序以支持透明度和可信度，并允许知情选择。 抵销不在本文件的范围内。

This document specifies requirements and guidelines for the quantification and reporting of the process carbon footprint of biobased plastics (see ISO 22526-1), being a partial carbon footprint of a bioplastic product, based on ISO 14067 and consistent with International Standards on life cycle assessment (ISO 14040 and ISO 14044). This document is applicable to process carbon footprint studies (P-CFP) of plastic materials, being a partial carbon footprint of a product, whether or not the results are intended to be publicly available. Requirements and guidelines for the quantification of a partial carbon footprint of a product (partial CFP) are provided in this document. The process carbon footprint study is carried out according to ISO 14067 as a partial carbon footprint, using the specific conditions and requirements specified in this document. Where the results of a P-CFP study are reported according to this document, procedures are provided to support transparency and credibility, and also to allow for informed choices. Offsetting is outside of the scope of this document.
