Chinese battery manufacturer CATL said it achieved carbon neutrality across its core operations in 2025, meeting a target it announced three years ago.
The company said all 20 of its battery plants had been certified as carbon neutral. However, its announcement did not identify the certifying organisation, disclose the volume of residual emissions offset or explain which carbon credits had been used.
CATL said zero-carbon sources accounted for 100% of electricity consumed by its core operations in 2025. The company has consumed more than 18 billion kWh of zero-carbon electricity since 2023.
Energy consumption per unit of production at its battery plants fell by 28% between 2022 and 2025, while carbon emissions intensity declined by approximately 77%, according to the company. CATL claimed its measures had avoided more than 10 million tonnes of CO₂-equivalent emissions over the three years.
The manufacturer uses its Carbon Chain Management System, introduced in 2022, to monitor and calculate emissions from its plants and production lines. The system now contains more than 1,000 product and raw-material models and includes data from battery production and core upstream suppliers.
Proving what is possible with carbon neutrality
Robin Zeng, chairman and CEO of CATL, said: “Before contributing to global carbon rules and standards, CATL must first prove what is possible through our own industrial practice.
“As the world ramps up efforts toward net-zero, zero-carbon batteries will not be a choice but a necessity in the near future. We are ready to share our technologies and experience with partners across the industry, helping to shape global carbon standards and advance industry-wide decarbonisation.”
CATL is now working towards carbon neutrality across its value chain by 2035. The company said more than 80% of lifecycle emissions from its products originate in the supply chain, with total value-chain emissions more than five times those produced by its core operations.
It has established baseline carbon data for more than 100 core Tier 1 suppliers and intends eventually to cover all key upstream operations.
Under new procurement guidelines, new suppliers will be required to provide product carbon-footprint data from 2027. Renewable electricity use and energy efficiency will also be considered in annual supplier reviews, with better-performing suppliers potentially receiving priority in order allocation and support through long-term agreements.
CATL will initially work with 30 core suppliers through a new supply-chain decarbonisation initiative. Its plans also include lower-carbon raw materials and production processes, zero-carbon logistics and expansion of its battery recycling network through subsidiary Brunp Recycling.
The company is targeting 100% green electricity use across its value chain by 2035.
