电动汽车和动力电池为全球人民的绿色出行提供了便利，更为全球应对低碳减排提供了方法和实践路径。目前，在全球碳中和目标和产品数字护照的双重驱动下，以锂电池为代表的新能源作为核心清洁能源，其全生命周期碳足迹研究对推动能源转型具有重要意义。针对即将执行的国内外电池碳足迹核算要求，便于相关监管人员和从业人员对电池产品碳足迹核算的理解，本文梳理了国内外电池碳足迹标准现状、简要解析即将执行的QC/T1247—2025《温室气体 产品碳足迹量化方法与要求 汽车动力蓄电池》，最后针对电池碳足迹核算和监管提出几点建议。截至目前，关于电池碳足迹核算的研究已取得显著进展，其边界条件、功能单位及声明单位已基本达成统一，然而在数据的可获得性、精确性以及国际数据的互认方面仍面临诸多挑战，未来研究仍需朝向动态化、智能化与系统化的方向深入推进，以更为精准地助力我国动力电池产业突破绿色贸易壁垒，进而提升其在全球市场的国际竞争力。

Electric vehicles and power batteries have enabled sustainable mobility worldwide and established concrete pathways for global low-carbon transition. Aligned with the international carbon neutrality objective and the emerging Digital Product Passport framework， lithium-based energy storage systems serve as the cornerstone of clean energy infrastructure. Accurate quantification of their full life-cycle carbon footprint is critical to accelerating energy system transformation and enabling evidence-based policy design. To address the escalating domestic and international regulatory demands for battery carbon accounting， and to enhance the operational understanding of stakeholders—including regulators， manufacturers， and certification bodies—this paper systematically reviewed the current landscape of global battery carbon footprint standards. It provided a focused analysis of ?QC/T 1247-2025 Greenhouse gases — Quantitative methods and requirements of product carbon footprint — Traction Batteries of Vehicles?. Based on this review， actionable recommendations were proposed to strengthen carbon footprint governance. Up to now， significant progress has been made in research related to battery carbon footprint， with basic unificaiotn of system boundaries?， functional carbon footprnt and declaration units. However， challenges remain in terms of data availability， accuracy， and international data mutual recognition?. Future research must advance toward ?dynamic， intelligent， and system-integrated modeling frameworks? to deliver real-time， traceable， and scalable carbon accounting capabilities. Such innovations are essential to provide robust scientific support for the low-carbon evolution of traction batteries and to empower China’s power battery industry in overcoming green trade barriers and securing a leadership position in the global market.Up to the present， substantial advancements have been achieved in research concerning the carbon footprint accounting of batteries， with a general consensus established on boundary conditions， functional units， and declaration units. Nevertheless， numerous challenges persist regarding data accessibility， precision， and mutual recognition of international data. Future research endeavors should persist in advancing towards dynamism， intelligence， and systematization， so as to more precisely facilitate China's power battery industry in overcoming green trade barriers and bolstering its global market competitiveness.
