3.1 Terminology related to greenhouse gas 3.1.1

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.

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.

The unit comparing the radiative forcing (3.1.2) of a certain greenhouse gas with that of carbon dioxide.

The carbon dioxide equivalent of a given greenhouse gas is equal to the mass of that greenhouse gas multiplied by its global warming potential.

The total amount of greenhouse gases released into the atmosphere during a specific period (in units of mass).

In this document, greenhouse gas emission is equated with carbon emission.

The total amount of greenhouse gases removed from the atmosphere during a specific period (in units of mass).

The greenhouse gas emission that still exists after all possible emission reduction measures have been taken.

The coefficient relating activity data to greenhouse gas emission.

A unit or process that releases greenhouse gas into the atmosphere.

The process of removing greenhouse gas from the atmosphere.

A list of greenhouse gas sources and greenhouse gas emissions owned or controlled by industrial enterprises.

3.2 Terminology related to life cycle assessment 3.2.1

The product-related, continuous, and interconnected stages, from raw material acquisition or generation from natural resources to end-of-life processing. The compilation and assessment of a product system’s inputs, outputs and potential environmental impacts throughout its entire life cycle (3.2.1). See also 3.2.4 of GB/T 24001-2016 for the definition of "environmental impact". A life cycle assessment (3.2.2) stage, which involves the compilation and quantification of inputs and outputs throughout the entire product life cycle. A life cycle assessment (3.2.2) stage, which aims to understand and assess the magnitude and significance of the product system’s impact on the potential environment throughout the product's entire life cycle. A stage, in the life cycle assessment (3.2.2), in which the results of the inventory analysis or impact assessment are evaluated according to the specified objectives and scope to form conclusions and recommendations. The point at which a product or resource is scrapped at the end of its life cycle. […]

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. 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. The greenhouse gas emissions generated by major production processes in automobile manufacturing, such as stamping, welding, painting, and final assembly. 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. The greenhouse gas emissions generated from major production processes in the production of automotive parts or assemblies, such as injection molding, casting, and machining. A complete technological process and equipment consisting of each process in product manufacturing. Processes, facilities, and equipment that serve the production system. refrigeration, instrument repair, lighting, warehouses and raw material storage areas within the factory, as well as safety and environmental protection equipment and facilities. The production command system (factory headquarters) and the departments and units within the factory area that serve production. Including staff canteens, workshop bathrooms, and health stations. Working substances consumed during the production process that are not used as raw materials or incorporated into the product, but which require direct energy consumption during production or preparation.
