3.1 Terminology related to greenhouse gas 3.1.1 greenhouse gas; GHG Gaseous components in the atmosphere that exist naturally or are produced by human activities and can absorb and emit radiation with wavelengths in the infrared spectrum from the Earth's surface, atmosphere, and clouds. Note. The greenhouse gases covered in this document include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3). [Source. GB/T 24067-2024, 3.2.1] 3.1.2 radiative forcing The net radiation variation in the vertical direction of the tropopause, which is caused by external forcing, such as changes in the internal climate system, such as changes in carbon dioxide concentration or solar radiation. 3.1.3 global warming potential; GWP The coefficient that correlates the effect of radiative forcing (3.1.2) of a unit mass of a certain greenhouse gas over a given time period with the effect of radiative forcing of an equal amount of carbon dioxide. [Source. GB/T 24067-2024, 3.2.4] 3.1.4 carbon dioxide equivalent; CO2e The unit comparing the radiative forcing (3.1.2) of a certain greenhouse gas with that of carbon dioxide. Note. The carbon dioxide equivalent of a given greenhouse gas is equal to the mass of that greenhouse gas multiplied by its global warming potential. [Source. GB/T 24067-2024, 3.2.2] 3.1.5 greenhouse gas emission; GHG emission The total amount of greenhouse gases released into the atmosphere during a specific period (in units of mass). Note. In this document, greenhouse gas emission is equated with carbon emission. [Source. GB/T 24067-2024, 3.2.5, modified] 3.1.6 greenhouse gas removal; GHG removal The total amount of greenhouse gases removed from the atmosphere during a specific period (in units of mass). [Source. GB/T 24067-2024, 3.2.6] 3.1.7 residual greenhouse gas emission Packaging designed to contain one or more items or to pack bulk materials for the purpose of transport, handling or distribution. [Source. ISO 14083.2023, 3.4.3]4 Organizational level
4.1 Terminology related to manufacturing stage 4.1.1 GHG emissions from vehicle enterprise The greenhouse gas emissions generated within a specific time period by an independent accounting unit whose main business is the production of complete vehicles (motor vehicles, towed vehicles, motorcycles, etc.). 4.1.2 GHG emissions from automotive parts product enterprise The greenhouse gas emissions generated within a specific time period by an independent accounting unit whose main business is the production of parts (new parts products, remanufactured products, recycled parts products from scrap vehicles, and vehicle recycling products, etc.). 4.1.3 GHG emissions from raw material manufacturing enterprise The greenhouse gas emissions generated within a specific time period by an industrial enterprise that directly processes mining products and produces various raw materials. 4.1.4 GHG emissions from traction battery production enterprise The greenhouse gas emissions generated within a specific time period by an independent accounting unit whose main business is the production of traction batteries (lithium-ion, sodium-ion, nickel-metal hydride, etc. traction batteries). 4.1.5 GHG emissions from engine manufacturing enterprise The greenhouse gas emissions generated within a specific time period by an independent accounting unit whose main business is the production of engines (internal combustion engines, external combustion engines, jet engines, electric motors, etc.). 4.1.6 GHG emissions per unit of automotive parts production The ratio of total greenhouse gas emissions from an automotive parts enterprise during the statical reporting period to the total number of qualified automotive parts produced during the same period. 4.1.7 GHG emissions per unit of automotive material production The ratio of total greenhouse gas emissions from an automotive material enterprise during the statical reporting period to the total number of qualified materials produced during the same period. 4.1.8 GHG emissions per unit of vehicle production The ratio of total greenhouse gas emissions from a vehicle enterprise during the statical reporting period to the total number of qualified products produced during the same period. 4.1.9 automobile production process emissions The greenhouse gas emissions generated by major production processes in automobile manufacturing, such as stamping, welding, painting, and final assembly. 4.1.10 battery production process emissions The greenhouse gas emissions generated during the production of traction batteries, including slurry preparation, electrode preparation, core pack preparation, cell assembly, drying and liquid injection, formation and capacity testing, and battery module assembly. 4.1.11 parts production process emissions The greenhouse gas emissions generated from major production processes in the production of automotive parts or assemblies, such as injection molding, casting, and machining. 4.1.12 4.3.13 GHG emissions per unit of vehicle traction battery recycling product The ratio of total greenhouse gas emissions from an enterprise engaged in the vehicle traction battery recycling during the statical reporting period to the total amount of qualified recycled products produced during the same period.5 Product level
5.1 Terminology related to complete vehicle products 5.1.1 carbon footprint of passenger car The combined greenhouse gas emissions and removals generated by the motor vehicle, which is designed, manufactured and technically characterized as primarily for carrying passengers and their personal belongings or temporary items, with a maximum of 9 seats including a driver's seat, within a specific life cycle. 5.1.2 carbon footprint of bus The combined greenhouse gas emissions and removals generated by the motor vehicle designed, manufactured, and technically characterized for carrying passengers and their personal belongings, with more than 9 seats including the driver's seat, within a specific life cycle. 5.1.3 carbon footprint of goods vehicle The sum of greenhouse gas emissions and removals generated within a specific life cycle by the motor vehicle that is designed, manufactured, and technically primarily for carrying goods or towed vehicles, including automobiles equipped with certain special equipment or appliances but whose primary purpose is to carry goods and which are not special motor vehicles or special-purpose vehicles. 5.1.4 carbon footprint of commercial vehicle The sum of greenhouse gas emissions and removals generated by the motor vehicle designed, manufactured, and technically used for transporting people and goods over a specific life cycle. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
