GB/T 24067-2024 Greenhouse gases - Carbon footprint of products - Requirements and guidelines for quantification
1 Scope
This document specifies principles, requirements and guidelines for the quantification and reporting of the carbon footprint of a product (CFP) and the partial carbon footprint of a product (partial CFP), in a manner consistent with standards on life cycle assessment (LCA) (GB/T 24040 and GB/T 24044).
This document is applicable to CFP studies, the results of which provide the basis for different applications. Carbon offsetting and communication of CFP or partial CFP information are outside the scope of this document.
This document addresses only a single environmental impact category: climate change. It does not assess any social or economic impacts, or any other environmental impacts potentially arising from the life cycle of a product.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 24025-2009, GB/T 24040-2008, GB/T 24044-2008, GB/T 32150-2015, and ISO/TS 14027:2017, as well as the following apply.
3.1 Quantification of the carbon footprint of a product
3.1.1
carbon footprint of a product; CFP
sum of GHG emissions and GHG removals in a product system, expressed as carbon dioxide equivalents and based on a life cycle assessment using the single environmental impact category of climate change
Note 1: A CFP can be disaggregated into a set of figures identifying specific GHG emissions and removals (see Table 1). A CFP can also be disaggregated into the stages of the life cycle.
Note 2: The results of the quantification of the CFP are documented in the CFP study report expressed in mass of CO2e per functional unit.
3.1.2
partial carbon footprint of a product; partial CFP
sum of GHG emissions and GHG removals of one or more selected stage(s) or process(es) in a product system within the life cycle, expressed as carbon dioxide equivalents
Note 1: A partial CFP is based on or compiled from data related to (a) specific process(es) or footprint information modules, which is (are) part of a product system and can form the basis for quantification of a CFP.
Note 2: "Footprint information module" is defined in ISO 14026:2017, 3.1.4.
Note 3: The results of the quantification of the partial CFP are documented in the CFP study report expressed in mass of CO2e per declared unit.
3.1.3
carbon footprint of a product systematic approach; CFP systematic approach
set of procedures to facilitate the quantification of the CFP for two or more products of the same organization
3.1.4
carbon footprint of a product study; CFP study
all activities that are necessary to quantify and report a CFP or a partial CFP
3.1.5
carbon footprint of a product study report; CFP study report
report that documents the CFP or partial CFP study, and shows the decisions taken within the study
Note: The CFP study report demonstrates that the provisions of this document are met.
3.1.6
quantification of the carbon footprint of a product; quantification of the CFP
activities that result in the determination of a CFP or a partial CFP
Note: Quantification of the CFP or the partial CFP is part of the CFP study.
3.1.7
carbon offsetting
mechanism for compensating for all or a part of the CFP or the partial CFP through the prevention of the release of, reduction in, or removal of an amount of GHG emissions in a process outside the product system under study
Example: Investment outside the relevant product system, e.g. in renewable energy technologies, energy efficiency measures, afforestation/reforestation.
Note 1: Carbon offsetting is not allowed in the quantification of a CFP or a partial CFP, and communication of carbon offsetting is outside of the scope of this document (see 6.3.5.1).
Note 2: Footprint communication and relevant claims regarding carbon offsetting and carbon neutrality are covered in ISO 14021:2016/Amd 1:2021 and ISO 14026:2017.
Note 3: Adapted from the definition of "offsetting" in ISO 14021:2016/Amd 1:2021, 3.1.12.
3.1.8
product category
group of products that can fulfill equivalent functions
[Source: GB/T 24025-2009, 3.12]
3.1.9
product category rules; PCR
set of specific rules, requirements and guidelines for developing Type III environmental declarations and footprint communications for one or more product categories
Note 1: PCR include quantification rules conforming to GB/T 24044.
