3 Terms and Definitions
The terms and definitions defined in GB/T 19596-2017, GB/T 24067-2024, GB/T 26989-2011, and the following apply to this document.
3.1 carbon footprint of a product; CFP
Sum of GHG emissions and GHG removals in a product system, expressed as CO2 equivalent and based on life cycle assessment considering the single environmental impact category of climate change.
[Source: GB/T 24067-2024, 3.1.1]
3.2 partial carbon footprint of a product; partial CFP
Sum of GHG emissions and GHG removals in one or more selected stages or processes within the life cycle of a product, expressed as CO2 equivalent.
[Source: GB/T 24067-2024, 3.1.2]
3.3 process emission
Greenhouse gas emissions resulting from physical or chemical changes other than fuel combustion during production, waste treatment, disposal, and other processes.
[Source: GB/T 32150-2015, 3.8]
3.4 functional unit
Benchmark unit used to quantify the function of a product system.
[Source: GB/T 24067-2024, 3.3.7]
3.5 declared unit
Benchmark unit used to quantify the partial carbon footprint of a product.
Example: mass (1 kg of crude steel), volume (1 liter of crude oil).
[Source: GB/T 24067-2024, 3.3.8]
3.6 system boundary
Set of criteria determining which unit processes are part of a product system.
[Source: GB/T 24067-2024, 3.3.4]
3.7 activity data
Quantitative measure(s) of an activity resulting in greenhouse gas emissions.
Note: Such as consumption of various fossil fuels, usage of raw materials, purchased electricity, purchased heat, etc.
[Source: GB/T 32150-2015, 3.12]
3.8 primary data
Quantitative value for a process or activity obtained by direct measurement or calculation based on direct measurement.
Note 1: Primary data is not necessarily from the product system under study, as it may involve other comparable product systems.
Note 2: Primary data may include greenhouse gas emission factors or greenhouse gas activity data.
[Source: GB/T 24067-2024, 3.6.1]
3.9 site-specific data
Primary data obtained from within the product system.
Note 1: All site-specific data are primary data, but not all primary data are site-specific, as data may be obtained from different product systems.
Note 2: Site-specific data includes the greenhouse gas emissions and removals of a specific unit process within a site.
[Source: GB/T 24067-2024, 3.6.2]
3.10 secondary data
Data that does not meet the requirements for primary data.
Note 1: Secondary data is data verified by authoritative bodies with credible reliability, which may originate from databases, public literature, national emission factors, calculated estimates, or other representative data. The use of localized databases is recommended.
Note 2: Secondary data may include data obtained from substitute processes or estimates.
[Source: GB/T 24067-2024, 3.6.3]
3.11 data quality
Characteristics of data's ability to meet stated requirements.
[Source: GB/T 24044-2008, 3.19]
3.12 data quality rating; DQR
Semi-quantitative assessment result of data quality based on temporal representativeness, technological representativeness, geographical representativeness, and data source representativeness.
3.13 carbon offsetting
Mechanism using avoided, reduced, or removed greenhouse gas emissions outside the system boundary of the product under study to fully or partially compensate for the product carbon footprint or partial product carbon footprint.
