CATL says in 2025, its core operations were powered by 100% zero-carbon electricity
The company reported more than 10 million tons of cumulative carbon emission reductions since 2023
Its next target covers the full battery value chain by 2035, for which it has announced procurement guidelines for its suppliers from 2027 onward
China-headquartered battery and technology group CATL has announced achieving its 2025 carbon neutrality target for core operations, with all 20 of its battery manufacturing plants certified as carbon neutral. It now targets achieving full value-chain carbon neutrality by 2035.
In 2025, the company said its core operations used 100% zero-carbon electricity. It consumed more than 18 billion kWh of zero-carbon power cumulatively since 2023, while the energy use per unit of product at its battery manufacturing bases fell 28% from 2022 levels.
“Carbon neutrality cannot be built on estimates alone. It requires reliable data, clear boundaries and systematic execution,” said Jiang Li, CATL’s vice president, board secretary and head of its Corporate Sustainable Development Management Committee.
CATL, one of the world’s largest battery manufacturers, says its Carbon Chain Management System (CCMS), developed in 2022, monitors emissions across the company’s production operations and core upstream suppliers. The system now covers more than 1,000 product and raw material models.
CATL’s roadmap to reach carbon neutrality across its full value chain by 2035 now expands to its suppliers, since the supply chain accounts for more than 80% of emissions across its product lifecycle.
From 2027 onward, its suppliers will be required to provide product carbon footprint data. Renewable electricity use and energy efficiency will also be included in supplier reviews. Under comparable conditions, suppliers with stronger low-carbon performance may receive priority in order allocation and support through long-term agreements.
CATL said it has already established baseline carbon data for more than 100 core Tier 1 suppliers and aims to achieve full data coverage across key upstream links. It will initially work with 30 core suppliers through its Zero-Carbon Supply Chain Empowerment Initiative.
The company also plans to expand battery recycling through Brunp Recycling and promote zero-carbon logistics across the industry chain.
“CATL will advance value-chain decarbonization across key areas including material innovation, material manufacturing, green logistics, and battery recycling. This requires collaboration across the entire battery value chain,” said Bryan Huang, Head of CATL’s Procurement Center.
The backgrounder accompanying the launch said CATL’s Sichuan Yibin plant has operated on 100% zero-carbon electricity for five consecutive years. Its Thuringia plant in Germany also achieved 100% green electricity use in 2025, including 3.13 million kWh generated and consumed from distributed rooftop solar panels.
CATL said its 2035 plan is intended to extend carbon management from individual manufacturing sites across the wider battery ecosystem.
CATL Chairman and CEO Robin Zeng said, “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 decarbonization.”
