1 Scope

China's national requirements for greenhouse gas emission accounting and reporting by producers of fired wall, roof and paving building materials. It is Part 37 of GB/T 32151 and specifies the calculation steps, the accounting boundary and emission sources, the accounting requirements and emission calculation, the data quality management, and the content and format of the report, with seven annexes including a normative method for calculating the emissions from burning coal gangue as a substitute raw fuel and a normative annex on the selection of the electricity carbon dioxide emission factor. The sector is the brick and tile industry: fired clay bricks, hollow blocks, roof tiles and paving units, made by forming clay or shale and firing it in a kiln. It is enormous in China and it is fragmented, with a very large number of small plants, and its emissions come from two sources. The first is the fuel burnt to fire the kiln. The second is the carbonate content of the raw material, which decomposes during firing and releases carbon dioxide chemically - a process emission that is a property of the clay rather than of the fuel. What gives this part its distinctive clause is coal gangue. Gangue is the waste rock brought up with coal, it is produced in enormous quantity, it contains enough residual carbon to burn, and the brick industry uses it as both raw material and fuel at once: it is formed into the brick and burns from within as the brick is fired. That is genuinely useful - it consumes a waste that would otherwise be tipped, and it displaces purchased fuel - and it is genuinely difficult to account for, because the carbon is inside the product rather than in a metered fuel supply. Annex D gives the method. Issued on 29 September 2024 and in force since 1 April 2025.

This document specifies the calculation steps and boundaries of greenhouse gas emissions from sintered wall, roof and road building materials production enterprises. and emission sources, accounting requirements and emission calculations, data quality management requirements, and report content and format. This document is applicable to the production of sintered wall bricks and blocks, sintered wall panels, sintered pavement bricks and pavement panels, sintered tiles and other sintered products. Calculation and reporting of greenhouse gas emissions from production enterprises operating businesses.
