Product Carbon Footprint Data Quality Control Standard Summary

Standard Name: ICS1104070Y89 T/CMAT/CMAXXYYYY—2024 Product Carbon Footprint Data Quality Control General Requirements
Issuance Information: Draft for public comment, published November 30, 2024, effective December 1, 2024, issued by the China Metrology Association.
Purpose: This standard aims to standardize and unify data quality in product carbon footprint calculations, ensuring accuracy, reliability, and transparency. It supports China's green and low-carbon transition by providing a framework for carbon footprint management and fostering sustainable practices.
Scope: Applies to the quality control of product carbon footprint and partial product carbon footprint quantification data. It aligns with life cycle assessment (LCA) standards (e.g., GB/T24040 and GB/T24044) and can be used for various product studies.
Key Requirements:

Data Collection: Emphasizes gathering primary, secondary, and site-specific data; data quality features include timeliness, geographical relevance, and uncertainty analysis.
Data Confirmation: Validates data through methods like mass and energy balance to meet quality criteria.
Allocation and Calculation: Ensures accurate distribution of inputs/outputs and computes carbon footprints using standardized methods, considering greenhouse gas emissions and offsets.
Update and Protection: Promotes regular data updates and protects data integrity using technologies like blockchain and encryption.
Data Quality Assessment: Includes multi-level analysis, uncertainty evaluation, and compliance checks to enhance reliability.
Normative References: GB/T24025-2009, GB/T24040-2008, GB/T24044-2008, GB/T32150-2015, DB31/T1071.
Additional Elements: Defines key terms like carbon footprint, allocation principles, and lifecycle assessment. Includes an appendix on uncertainty analysis for robust data evaluation.
