3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 32150 and the following apply.
3.1
greenhouse gas
gaseous constituent of the atmosphere, both natural and anthropogenic, that absorbs and emits radiation at specific wavelengths within the spectrum of infrared radiation emitted by the Earth's surface, the atmosphere and clouds
Note: The greenhouse gases covered by this document include carbon dioxide (CO2), trifluoromethane (CHF3), difluoromethane (CH2F2), carbon tetrafluoride (CF4), hexafluoroethane (C2F6), perfluoropropane (C3F8), octafluorocyclobutane (c-C4F8), octafluorocyclopentane (C5F8), sulfur hexafluoride (SF6) and nitrogen trifluoride (NF3).

3.2
reporting entity
corporate enterprise with greenhouse gas emission behavior or an independent accounting unit regarded as a legal person
[Source: GB/T 32150-2015, 3.2]
3.3
electronics manufacturing enterprise
legal enterprise or independent accounting unit regarded as a legal person whose primary business activity is the manufacture of computer communication equipment, and other electronics
3.4
fossil fuel combustion emission
greenhouse gas emission generated during oxidative combustion of fossil fuels
3.5
process emission
greenhouse gas emission caused by physical or chemical changes other than fuel combustion in the process of production, waste treatment and disposal
[Source: GB/T 32150-2015, 3.8]
3.6
emission from purchased electricity and heat
carbon dioxide emission associated with the production links generating purchased electricity and heat consumed by enterprises
Note: Heat includes steam and hot water.
[Source: GB/T 32150-2015, 3.9]
3.7
emission from exported electricity and heat
carbon dioxide emission associated with the production links generating electricity and heat exported by enterprises
[Source: GB/T 32150-2015, 3.10]
3.8
activity data
characterization value of the amount of production or consumption activity that leads to the greenhouse gas emission
Note: For example, the consumption amount of various fossil fuels, the use amount of raw materials, the purchased electricity amount, the purchased heat amount, etc.
[Source: GB/T 32150-2015, 3.12, modified]
3.9
emission factor
factor representing the greenhouse gas emissions per unit of production or consumption activity
[Source: GB/T 32150-2015, 3.13]
3.10
carbon oxidation rate
percentage of carbon in the fuel that is completely oxidized during combustion
[Source: GB/T 32150-2015, 3.14]
3.11
etching
process of selectively etching or stripping the surface of a semiconductor substrate or the film covering such surface according to the mask pattern or design requirements
3.12
chemical vapor deposition; CVD
process in which steam containing a gaseous reactant or a liquid reactant constituting an element of a thin film and other gases required for the reaction are introduced into a reaction chamber, where a chemical reaction occurs on the substrate surface to form a thin film
3.13
global warming potential
GWP
coefficient describing the radiative forcing impact of a unit mass of a given greenhouse gas relative to that of an equivalent mass of carbon dioxide over a given period of time
[Source: GB/T 32150-2015, 3.15, modified]
3.14
carbon dioxide equivalent
CO2e
amount of carbon dioxide that would produce the same radiative forcing as a given mass of a specific greenhouse gas
Note: The carbon dioxide equivalent is calculated using the mass of a given greenhouse gas multiplied by its GWP.

4 Accounting boundary
4.1 General
A reporting entity shall account and report the greenhouse gas emission generated by its production system with the enterprise legal person or the independent accounting unit regarded as a legal person as the boundary. A production system includes the main production system, the auxiliary production system and the ancillary production system directly serving production. Wherein, the auxiliary production system includes the motive power, power supply, water supply, laboratory test, machine maintenance, warehousing, and transporting systems; the ancillary production system includes the production command system (factory headquarters) and the departments and units serving the production in the factory area (such as the staff canteen, the workshop bathroom and the health station).
