碳关税时代下，国内动力电池碳足迹开启申报，27年常态化

Core Viewpoint - The urgency for battery companies arises from the impending "carbon tariff" era starting in 2026, necessitating carbon footprint certification for key export products, including lithium batteries [2][3]. Group 1: Carbon Footprint Certification Development - China has established a product carbon footprint certification pilot network across 25 provinces, marking a significant step in the carbon footprint standardization process, particularly for the lithium battery industry [3]. - The transition from "external" to "internal" carbon footprint certification reflects a shift towards mandatory low-carbon practices and certification needs within the industry [3][4]. - The Ministry of Industry and Information Technology (MIIT) will release a carbon footprint accounting system for lithium batteries in June 2024, with mandatory reporting for battery products exceeding 2 kWh by the end of 2025 [4]. Group 2: Mandatory and Essential Aspects of Carbon Footprint Reporting - The MIIT mandates that by the end of 2026, battery pack manufacturers must complete carbon footprint reporting for at least five typical products across all chemical systems, with regular reporting starting in 2027 [5]. - Carbon tariffs have become a critical factor in international trade, with major markets like the EU, US, and Japan requiring carbon footprint assessments for battery exports, making compliance a necessary threshold for domestic companies [6]. Group 3: Data Collection for Carbon Footprint Assessment - Companies must gather data covering the entire lifecycle of the product, including material acquisition, manufacturing, distribution, and recycling, to calculate the carbon emissions associated with battery production [7]. - Two key data types are required: "activity data" from the four lifecycle stages and "background data" on carbon emissions from energy sources and materials used [7]. Group 4: Market Implications and Future Directions - The certification process emphasizes the need for battery companies to evaluate and potentially shift towards lower carbon-emitting chemical systems, as the market dynamics may change based on carbon emissions [10]. - Sodium-ion batteries present a promising low-carbon alternative, as their materials can be sourced from by-products of the chemical industry, significantly reducing emissions from raw material extraction [11]. - The timeline for establishing comprehensive carbon management capabilities across all product lines is tight, with a one-year window before the 2027 regular reporting begins [11].
