Introduction of GB/T 41638.3-2023

GB/T 41638.3-2023 Plastics - Carbon and environmental footprint of biobased plastics - Part 3: Process carbon footprint - Requirements and guidelines for quantification 1 Scope 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. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

ISO and IEC maintain terminological databases for use in standardization at the following addresses: ——ISO Online browsing platform: available at https://www.iso.org/obp ——IEC Electropedia: available at http://www.electropedia.org/ 3.1.1 process carbon footprint of a product; P-CFP process CFP; P-CFP sum of greenhouse gas emissions and removals of the cradle‑to‑gate processes of a product system, expressed as CO2 equivalents and based on the relevant stages or processes within the life cycle Note: The process carbon footprint, being a partial CFP, is based on or compiled from the cradle-to-gate processes or information modules which are part of a product system and may form the basis for quantification of a P-CFP. 3.2 Abbreviated terms CFP——carbon footprint of a product CFP-PCR——carbon footprint of a product – product category rules CO2e——carbon dioxide equivalent dLUC——direct land use change GHG——greenhouse gas GWP——global warming potential iLUC——indirect land use change IPCC——Intergovernmental Panel on Climate Change LCA——life cycle assessment LCIA——life cycle impact assessment LCI——life cycle inventory analysis LUC——land use change P-CFP——Process carbon footprint of a product PCR——product category rules 4 Application In applying this document, it is advisable to take into consideration societal, environmental, legal, cultural, political and organizational diversity, as well as differences in economic conditions. Further, it is not intended to provide a basis for trade regulations, legal actions, complaints, defences or other claims in any international, domestic or other proceeding, nor is it intended to be cited as evidence of the evolution of customary international law (adopted from ISO 26000). Possible applications of this document include the provision of information for research and development of products, improvement of technologies and communication, where relevant.
