1 Scope

GB/T 32151.23-2024 is the crop farming part of the Chinese greenhouse gas accounting and reporting series. Cropping emissions are dominated by two sources that behave nothing like an industrial stack: nitrous oxide released from nitrogen applied to soil, whose emission factor depends on the fertiliser type, the soil and the climate, and methane from flooded rice paddy, which depends on the water management regime and on the organic amendments used. Fuel and electricity for machinery and irrigation come third. The standard sets the accounting boundary for a farming organisation, the calculation steps and methods for each of those sources, the data quality management requirements, and the content and format of the report, with informative annexes giving the default parameter values and the data quality guidance for organisations that cannot measure directly. It is the document that makes a Chinese farm's emissions a reported number rather than an estimate, and for anyone assessing agricultural supply chains sourced from China it defines what those numbers mean. It takes effect on 1 May 2025.

This document specifies the accounting boundaries, accounting steps and methods, data quality management, Report content and format. This document applies to the accounting and reporting of greenhouse gas emissions by plantation organizations.
