Plastics - Carbon and environmental footprint of biobased plastics - Part 3: Process carbon footprint, requirements and guidelines for quantification (ISO 22526-3:2020)

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.

Ta dokument določa zahteve in smernice za količinsko opredelitev in poročanje o ogljičnem odtisu postopkov polimernih materialov na biološki osnovi (glej standard ISO 22526-1), ki je delni ogljični odtis izdelka iz biopolimernih materialov in temelji na standardu ISO 14067 ter je skladen z mednarodnima standardoma za oceno življenjskega cikla (ISO 14040 in ISO 14044).
Ta dokument se uporablja za raziskave o ogljičnem odtisu postopkov (P-CFP) polimernih materialov, ki je delni ogljični odtis izdelka, ne glede na to, ali so rezultati namenjeni javni objavi.
V tem dokumentu so podane zahteve in smernice za količinsko opredelitev delnega ogljičnega odtisa izdelka (delni CFP). Raziskava o ogljičnem odtisu postopkov se izvaja v skladu s standardom ISO 14067 kot delni ogljični odtis z uporabo posebnih pogojev in zahtev, podanih v tem dokumentu.
Če se rezultati raziskave o ogljičnem odtisu postopkov poročajo v skladu s tem dokumentom, so na voljo postopki za zagotavljanje preglednosti in verodostojnosti ter za sprejemanje utemeljenih odločitev.
Izravnava je zunaj področja uporabe tega dokumenta.

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

Introduction

Increased use of biomass resources for manufacturing plastic products can be effective in reducing

global warming and the depletion of fossil resources.

Current plastic products are composed of biobased synthetic polymers, fossil-based synthetic polymers,

natural polymers and additives that can include biobased materials.

Biobased plastics refer to plastics that contain materials wholly or partly of biogenic origin.

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.

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.

process carbon footprint of a product
process CFP
P-CFP

sum of greenhouse gas emissions and removals of the cradle-to-gate processes of a product system,

expressed as CO equivalents and based on the relevant stages or processes within the life cycle

Note 1 to entry: 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.

5 Principles
5.1 General

The following principles are the basis for the subsequent requirements in this document.

5.2 Life cycle perspective, cradle to gate stage

The quantification of P-CFP takes into consideration all stages of the cradle-to-gate LCA of a product,

including acquisition of raw materials, production, transportation/delivery, as applicable.

NOTE 1 Under certain conditions, partial CFPs can be added together to quantify the CFP (see 6.1).

NOTE 2 By means of a systematic overview and life cycle perspective, the shifting of a
