1 Scope
This part of GB/T 32151 specifies the terms, accounting boundary, accounting procedures and methods, data quality management, report content and format, etc. for greenhouse gas emissions accounting and reporting by chemical production enterprises.
This part is applicable to the accounting and reporting of greenhouse gas emissions of chemical production enterprises. Enterprises with chemical product production activities as their main business may calculate greenhouse gas emissions according to the methods provided in this part and prepare enterprise greenhouse gas emission reports. In case of petrochemical or fluorine chemical production or other production activities accompanied with greenhouse gas emission behavior not covered in this part, the accounting and summary report shall be carried out with reference to the enterprise greenhouse gas emission accounting and reporting requirements of relevant industries.

3 Terms and definitions
For the purposes of this standard, the following terms and definitions apply.
3.1
greenhouse gas
gases available in the atmosphere and produced by human activities, which can trap and emit radiation produced by the Earth's surface, atmosphere and clouds and having wavelengths in the infrared spectrum
[GB/T 32150-2015, 3.1]
Note: The greenhouse gases involved in this part refer to carbon dioxide (CO2) and nitrous oxide (N2O).
3.2
reporting entity
corporate enterprises with greenhouse gas emission behavior or an independent accounting unit regarded as a legal person
[GB/T 32150-2015, 3.2]
3.3
chemical production enterprise
independent accounting unit mainly engaged in chemically producing basic chemical raw materials, fertilizers, pesticides, paints, dyes, synthetic resins, synthetic rubber, chemical fibers, rubber and its products, as well as special or daily chemicals
Note: In this part, petrochemical enterprises and fluorine chemical enterprises are not included.
3.4
accounting unit
units of the assets and facilities of the whole company which are independent and easy to identify and meter in material flow divided by reporting entity with multiple production and operation activity sites or industrial activity units according to certain logic (such as company organization and management structure, factory distribution, industrial activity classification, etc.) and the principle of non-repetition and non-omission
3.5
carbon source flow
fossil fuels, carbonaceous raw materials, carbonaceous products or carbonaceous wastes flowing into or out of accounting unit
3.6
fuel combustion emission
greenhouse gas emissions from fuel oxidation combustion
[GB/T 32150-2015, 3.7]
3.7
process emission
greenhouse gas emissions caused by physical or chemical changes other than fuel combustion during production and waste treatment and disposal
[GB/T 32150-2015, 3.8]
3.8
emission from purchased electricity and heat
carbon dioxide emission due to the electricity and heat production link which corresponds to purchased electricity and heat by the enterprise
Note: Heat includes steam, hot water, etc.
[GB/T 32150-2015, 3.9]
3.9
emission from exported electricity and heat
carbon dioxide emission due to the electricity and heat production link which corresponds to exported electricity and heat by the enterprise
[GB/T 32150-2015, 3.10]
3.10
carbon dioxide recycle
carbon dioxide produced by the reporting entity but recycled as raw material for production or supplied to other units and not discharged into the atmosphere
3.11
activity data
characteristic value of production or consumption activity that leads to greenhouse gas emission
Note: For example, the consumption of various fossil fuels, the consumption of raw materials, the purchased electricity and heat, etc.
[GB/T 32150-2015, 3.12]
3.12
emission factor
coefficient representing greenhouse gas emissions per production or consumption activity
[GB/T 32150-2015, 3.13]
3.13
carbon oxidation rate
percentage of carbon in fuel that is completely oxidized during combustion
[GB/T 32150-2015, 3.14]
3.14
global warming potential
GWP
coefficient that relates the radiative forcing effect of a certain greenhouse gas per unit mass in a given time period to the radiation intensity effect of the same amount of carbon dioxide
[GB/T 32150-2015, 3.15]
3.15
carbon dioxide equivalent
CO2e
amount of carbon dioxide whose radiation intensity is equivalent to the mass of a certain greenhouse gas
Note: Carbon dioxide equivalent is equal to the mass of a given greenhouse gas multiplied by its global warming potential.
