CATL Announces Carbon Neutrality Achieved Across All 20 Battery Plants

The world's largest electric vehicle battery manufacturer, CATL, announced that all 20 of its battery plants worldwide have achieved carbon neutrality at the core operations level, certified under ISO 14068-1 — a goal originally scheduled for 2025 and now delivered on time.

According to CATL, citing SNE Research data, the company held a 39.2% global market share in 2025 — ranking first in the power battery market for the ninth consecutive year and supplying nearly 40% of EV batteries worldwide. This carbon neutrality covers all currently operational production bases, spanning the full core operations process from cell manufacturing to system integration.

CATL stated that 100% of electricity used in its core operations in 2025 came from zero-carbon sources, with over 18 billion kWh of green electricity consumed cumulatively since 2023. Compared to 2022, energy consumption per unit of output fell by 28%, while carbon emissions per unit of output dropped by 77%; total CO₂-equivalent emissions reduced by more than 10 million tonnes between 2023 and 2025.

These achievements are built upon CATL's proprietary "Carbon Chain Management System (CCMS)," launched in 2022. The platform now integrates multidimensional carbon data — including factories, production lines, products, raw materials, and key suppliers — and has developed over 1,000 product- and material-specific carbon footprint models. CATL's Vice , Board Secretary, and Head of the Sustainable Development Management Committee, Jiang, emphasized: "Carbon neutrality cannot rely on estimation alone — it demands reliable data, clearly defined boundaries, and systematic execution."

It should be noted that ISO 14068-1 certification does not require zero emissions from facilities; rather, it mandates quantification and prioritized reduction of direct emissions, supplemented by verified carbon offset mechanisms to cover residual emissions. CATL has not disclosed its current net operational emissions volume, nor specified the breakdown of its zero-carbon electricity procurement — including on-site renewable generation, green electricity certificates (GECs), and other sourcing methods.

The truly daunting task lies ahead: CATL notes that over 80% of lifecycle emissions originate from its supply chain, where total value-chain emissions exceed core operational emissions by more than fivefold — encompassing non-controllable stages such as mineral mining, smelting and refining, chemical synthesis, material production, and logistics transportation.

To address this, CATL has established baseline carbon emission data for over 100 Tier-1 suppliers in the Yangtze River Delta region and plans to make product carbon footprint data a mandatory requirement for new supplier onboarding starting in 2027. Renewable energy usage rates and energy efficiency performance will also be integrated into annual supplier evaluations. Top-performing suppliers may receive preferential order allocation and long-term contract support. The first cohort of 30 core suppliers has already joined CATL's new Supply Chain Decarbonization Collaboration Program.

Looking toward full value-chain decarbonization by 2035, CATL's roadmap focuses on four pillars: low-carbon materials and process innovation; green electricity coverage across the supplier base; zero-carbon freight infrastructure development; and enhanced battery recycling circularity via its subsidiary Brunp Recycling. To date, CATL has supported over 60 distributed photovoltaic projects at supplier sites, generating more than 450 million kWh annually; future efforts will expand joint procurement of green electricity and GECs.

"Demonstrating decarbonization across the entire value chain — from materials innovation and manufacturing to green logistics and battery recycling — requires ecosystem-wide collaboration," said Huang Bo, Head of CATL's Procurement Center.
