Contemporary Amperex Technology Co. Limited, known as CATL, said it achieved carbon neutrality across its core operations by the end of 2025 and has for the first time laid out a structured path to reach carbon neutrality across its value chain by 2035. The company made the announcement at an August 17 event in Ningde, Fujian province, where it is headquartered.
CATL said it is the only battery company worldwide to have reached carbon neutrality in core operations while operating at terawatt-hour-scale shipment volumes. In this context, core operations refer to a company’s own production and operating activities, where emissions mainly come from electricity and heat used in factories. CATL said the larger the manufacturing scale, the more difficult this target becomes.
By the end of 2025, 20 of CATL’s battery plants had obtained ISO 14068-1 certification as zero-carbon factories, and zero-carbon electricity accounted for 100% of the power used in its core operations. The company said it produced 748 GWh of batteries in 2025, while sales were 2.3 times higher than in 2022.
According to CATL, it has used more than 18 billion kWh of zero-carbon electricity since 2023. Energy consumption per unit of output at its battery production bases fell 28% in 2025 from 2022 levels, while carbon emissions intensity declined about 77% over two years. The company said these gains resulted in cumulative emissions reductions of more than 10 million metric tons of carbon dioxide equivalent.
CATL said its main challenge now lies in the supply chain, which accounts for more than 80% of the lifecycle carbon emissions of its products and more than five times the emissions of its core operations. To address this, the company has built a full-chain carbon data traceability platform covering mineral extraction, raw-material refining, material synthesis, and component manufacturing. The platform is based on its Carbon Chain Management System, launched in 2022.
The company said calculations using real carbon data from more than 100 core tier-one suppliers have been completed, and more than 1,000 product and raw-material models have been built. CATL also said it plans to issue Green Procurement Guidelines and has launched a Zero-Carbon Supply Chain Empowerment Initiative with 30 core suppliers.
CATL remains the world’s largest EV battery supplier. It said its first-half 2026 global market share was 39.9%, according to SNE Research.
