AESC earns CDP A- rating, topping global battery manufacturers on climate

AESC has secured a CDP Climate Change A- rating for 2025, the highest score recorded by any lithium battery manufacturer globally in this reporting cycle. The recognition matters for EV adoption because it signals that the battery supply chain underpinning electric vehicles is increasingly transparent on carbon, a factor that regulators, fleet buyers, and investors now treat as a core criterion alongside performance.

AESC CDP rating sets a new climate benchmark for battery manufacturers

CDP runs one of the world’s most widely referenced environmental disclosure systems. Its assessments are used by investors, regulators, and customers to evaluate ESG performance and supply chain standards. Of more than 22,100 companies assessed in CDP’s 2025 Climate Change cycle, only 10% achieved an A- rating or higher. AESC’s score places it in that select group, making it the highest-rated lithium battery manufacturer in the entire cycle.

AESC aligns its global operations with the EU Battery Regulation and other international compliance requirements. The company has built an enterprise-wide emissions factor database using internationally recognised methodologies and works directly with upstream suppliers to strengthen carbon data modelling and management. That supplier engagement extends the company’s decarbonisation reach beyond its own factory gates and into the broader value chain.

Carbon neutrality milestones underpin the CDP climate result

AESC’s CDP performance builds on a series of verified milestones. In 2022, the company became the first battery manufacturer globally to achieve carbon neutrality across its Scope 1 and Scope 2 operations, with that status independently verified by the Carbon Trust. That same year it launched what it describes as the industry’s first carbon-neutral EV battery, followed in 2023 by the first carbon-neutral energy storage battery.

Across its global manufacturing network, AESC has pursued energy reduction through on-site upgrades including temperature and humidity control systems, smart sensor installations on production lines, and reuse of waste heat and water. The company also works closely with key suppliers to advance emissions reduction across the value chain. AESC states that this approach represents a scalable decarbonisation pathway for the broader lithium battery industry.

To date, AESC technology has powered more than 1.2 million electric vehicles and supported over 100 GWh of deployed energy storage capacity across 60 countries. The company supplies BMW, Mercedes-Benz, Nissan, Renault, Envision Energy, Fluence, and Nidec. The CDP A- rating further strengthens AESC’s position as a sustainability leader as it works with those customers and partners to support a more sustainable battery ecosystem.
