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.

[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.
