1 Scope

GB/T 32151.31-2024 is the wood processing part of the Chinese greenhouse gas accounting and reporting series. The sector has an accounting problem that most do not: a large part of its energy comes from burning its own residues, bark, sawdust and offcuts, whose carbon dioxide is biogenic and reported separately rather than counted, while the drying kilns and hot presses that consume most of the heat also emit from the adhesives and finishes applied. The carbon stored in the product itself is a further question the standard has to place. It sets the accounting boundary of a wood processing enterprise, the measurement and monitoring requirements, the calculation steps and methods for the fossil fuel combustion, the biomass combustion reported separately, the process emissions and the purchased energy, the data quality management and the content and format of the report, with informative annexes giving the reporting template and the default parameter values. It takes effect on 1 July 2025.

This document defines the terms and definitions related to the accounting and reporting of greenhouse gas emissions from wood processing enterprises, establishes general accounting principles, and It defines the measurement and monitoring requirements, data quality management, report content and format, and describes the accounting steps and methods. This document applies to greenhouse gas emissions from production enterprises whose main business is to produce related products using wood and wood materials as their main raw materials. Quantity accounting and reporting, for reference by manufacturers of bamboo, rattan, palm, straw and other products.
