1 Scope

GB/T 24067-2024 sets the Chinese requirements for quantifying the carbon footprint of a product. Product carbon footprints have moved from marketing to trade policy: the EU carbon border adjustment mechanism, the battery regulation and a growing number of customer requirements all demand a figure for the embodied emissions of a specific product, and Chinese exporters have to produce one that will be accepted. This standard is the Chinese method, aligned with ISO 14067. It sets the principles and the requirements for the quantification: the goal and scope definition and the functional unit, the system boundary and the cut-off criteria, the treatment of land use change, of biogenic carbon and of carbon storage, the allocation rules for multi-output processes and for recycling, the data quality requirements and the choice between primary and secondary data, the life cycle inventory and impact assessment, the interpretation, and the content of the study report and of any communication of the result. The 2024 edition replaces GB/T 24067-2020. For an exporter, a consultancy preparing a footprint or a customer assessing one, this is the governing method.

This document specifies the carbon footprint of products in a manner consistent with the Life Cycle Assessment standards (GB/T 24040 and GB/T 24044). Principles, requirements and guidelines for quantifying and reporting carbon footprint of products and products. This document is applicable to product carbon footprint related research, and its results can be applied to different scenarios. Carbon offset and product carbon footprint or product The exchange of partial carbon footprint information is outside the scope of this document. This document only addresses a single type of environmental impact, namely climate change, and does not assess other potential environmental impacts arising from the product life cycle. The possible social and economic impacts during the product life cycle are not evaluated.
