聚焦重点领域，国家将推进产品碳足迹因子数据库建设

Core Viewpoint - The establishment of a national product carbon footprint factor database is aimed at supporting the management system for product carbon footprints, with a goal to be initially constructed by 2027 and fully established by 2030 [1][2]. Group 1: Database Construction - The national product carbon footprint factor database will focus on key areas such as basic energy, bulk commodities, raw materials, and transportation, facilitating the management of carbon footprint factors throughout the product lifecycle [1][2]. - The database will include a mechanism for data sharing and integration, allowing various stakeholders to submit high-quality carbon footprint factor data, ensuring traceability and regular updates [2][4]. - The construction of the database will encourage the use of advanced technologies like artificial intelligence to enhance efficiency and data quality [5]. Group 2: Data Quality and Standards - The guidelines emphasize the importance of data quality evaluation based on representativeness, scientific rigor, and traceability, ensuring that the data reflects the actual energy and industrial conditions in China [4][6]. - The database will include comprehensive information on product carbon footprint factors, lifecycle models, and unit process data, adhering to relevant national and international standards [4][5]. - The establishment of a robust standard system for carbon footprint accounting is underway, with over 70 national standards and more than 100 group standards in development by the end of 2024 [5][6]. Group 3: Industry Implications - The product carbon footprint is a critical indicator for measuring the green and low-carbon levels of production enterprises and products, increasingly influencing international trade policies and market access rules [5]. - The ecological environment department is accelerating the research on carbon footprint factors for key sectors such as coal, electricity, oil, gas, steel, cement, and petrochemicals, aiming to enhance collaborative pollution reduction and carbon reduction efforts across the industry [6].
