1 Scope

GB/T 32151.10-2023 is Part 10 of the Chinese carbon emission accounting and reporting series and covers chemical production enterprises. Chemicals are the hardest sector to account for: emissions arise not only from fuel combustion and purchased electricity but from the process itself, where carbon enters as feedstock and leaves partly in the product and partly as CO2, and where the same site may run dozens of processes with different carbon balances. Getting the accounting boundary and the mass balance right is therefore the substance of the standard. It sets the accounting boundary, the measurement and monitoring requirements, and the calculation steps and methods for each emission source, together with the reporting, with informative annexes giving the report format template, default values for the relevant parameters and a data quality control plan template. It took effect on 1 July 2024.

This document specifies the accounting boundaries, measurement and monitoring, accounting steps and accounting methods for the accounting and reporting of carbon emissions of chemical production enterprises: data quality management, and report content and format:

Note: By convention, the term "carbon emissions" is used in this document to refer to greenhouse gas emissions, including carbon dioxide (CO2) and nitrous oxide (N2O): This document is applicable to the accounting and reporting of carbon emissions by chemical production enterprises: Enterprises whose main business is the production of chemical products can Calculate carbon emissions according to the method provided in this document and prepare corporate carbon emissions report:
