Greenhouse Gases - Quantification Methods and Requirements for Product Carbon Footprint of Road Vehicles
1 Scope
This document specifies the quantification scope, inventory analysis content, impact assessment methods, product carbon footprint report, etc., for the product carbon footprint of road vehicles.
This document applies to the accounting and reporting of carbon emissions for complete vehicles, components, and material products of automobiles, trailers, and motorcycles. Other types of products may refer to it for implementation.

3 Terms and Definitions
The terms and definitions defined in GB/T 24067, GB/T 26989, and the following apply to this document.
3.1 road vehicle products
Complete vehicle products used on roads such as automobiles, trailers, motorcycles, vehicle component products (including new components, remanufactured components, parts recycled from end-of-life motor vehicles, etc.), and material products (including virgin and recycled materials for vehicles).
3.2 biomass
Material of biological origin, excluding material embedded in geological formations and material transformed into fossil material.
Note 1: Includes organic material (living and dead), such as trees, crops, grasses, tree litter, algae, animals, manure, and biogenic waste.
Note 2: In this document, biomass excludes peat.
[Source: GB/T 24067-2024, 3.7.1]
3.3 biogenic carbon
Carbon derived from biomass.
[Source: GB/T 24067-2024, 3.7.2]
3.4 fossil carbon
Carbon contained in fossil material.
Example: Coal, petroleum and natural gas, and peat.
[Source: GB/T 24067-2024, 3.7.3]
3.5 product system
Collection of unit processes with elementary flows and product flows, performing one or more defined functions, and modeling the product life cycle.
[Source: GB/T 24067-2024, 3.3.2]
3.6 life cycle
Consecutive and interlinked stages of a product, from raw material acquisition or generation from natural resources to end-of-life treatment.
Note: Life cycle stages associated with a product include raw material acquisition, production, distribution, use, and end-of-life treatment.
[Source: GB/T 24067-2024, 3.4.2]
3.7 life cycle assessment; LCA
Compilation and evaluation of the inputs, outputs and the potential environmental impacts of a product system throughout its life cycle.
[Source: GB/T 24067-2024, 3.4.3]
3.8 functional unit
Benchmark unit used to quantify the function of a product system.
[Source: GB/T 24067-2024, 3.3.7]
3.9 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]
3.10 system boundary
Set of criteria determining which unit processes are part of a product system.
[Source: GB/T 24067-2024, 3.3.4]
3.11 benchmarking boundary
A fixed accounting boundary established to ensure the comparability of carbon footprint results among different automotive products.
Note: With technological progress and manageable costs, the benchmarking boundary will be expanded toward the system boundary as standards are updated, eventually achieving full alignment.
XX
3.12 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]
3.13 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]
3.14 site-specific data
Primary data obtained from within the product system.
