1 Scope

This document specifies the requirements and guidelines for the carbon footprint quantification report (see ISO 22526-1) of the bio-based plastics process: This document serves as

Part of the standards related to the carbon footprint of bio-based plastic products, based on ISO 14067 and life cycle assessment standards (ISO 14040 and

ISO 14044) requirements:

This document applies to studies of the process carbon footprint (P-CFP) of plastic materials, i:e: the partial carbon footprint of a product, whether or not the results are intended public:

This document provides the requirements and guidelines for the quantification of a product's partial carbon footprint (partial CFP): According to ISO 14067, use the specification in this document

According to the specific conditions and requirements specified, the carbon footprint of the process is studied as part of the carbon footprint:

This document specifies the analysis and calculation process and report content of P-CFP to ensure the transparency and credibility of the report:
