Low carbon assessment method for building materials

1 Scope

GB/T 44716-2024 gives the Chinese method for assessing the carbon performance of building materials. Construction is where the largest share of Chinese industrial emissions ends up, and the embodied carbon of the materials is now being asked for by developers, by green building rating schemes and by export customers; but a figure quoted without a defined boundary and a defined allocation rule is not comparable with anyone else's. The standard sets the assessment boundary, cradle to gate with the stages defined, the functional unit for each material category, the data requirements and their quality, the calculation of the greenhouse gas emissions from the raw materials, the energy, the transport and the process, the treatment of recycled input and of by-products and the allocation rules that go with them, the treatment of carbonation and of biogenic carbon where relevant, the benchmarking and grading of the result, and the report and its verification. It takes effect on 1 April 2025.

This document specifies the assessment requirements, assessment methods and assessment reports for low-carbon assessment of building materials. This document is applicable to enterprises or third parties who assess carbon reduction in the production stage of building materials and the avoidance of carbon dioxide emissions in the use stage.
