AESC Leads in Climate Change Reporting

In an impressive achievement for sustainability, AESC has garnered an A- rating from CDP in its Climate Change Report for the 2025 reporting cycle, marking the highest score among global battery manufacturers. This rating not only highlights AESC's commitment to responsible environmental practices but also solidifies its position as a leader in the electric vehicle (EV) battery sector.

Commitment to Sustainability

The CDP is recognized globally for its comprehensive framework in providing environmental data disclosures from companies. The criteria used for evaluation by the CDP are extensively utilized by investors, regulators, and consumers to gauge how well companies perform on environmental, social, and governance (ESG) standards as well as supply chain compliance. Among the over 22,100 companies assessed for the 2025 cycle, only 10% achieved an A- grade or higher, showcasing AESC's dedication and effectiveness in managing carbon emissions.

AESC's A- rating signifies robust and transparent emissions management frameworks, which are integral to the company's ongoing efforts towards decarbonizing its battery production processes. AESC strategically integrates emission reduction targets within its decision-making and daily operations, ensuring that sustainability is a key pillar of its global activities.

Innovative Carbon Management Strategies

AESC employs sophisticated carbon footprint management capabilities, primarily focusing on the usage of renewable energy and decarbonization within the industry. The company is adapting its operations to comply with the EU Battery Regulation and other international compliance requirements by establishing structured carbon management frameworks. As part of its efforts, AESC has developed an emission factor database based on internationally recognized methods and collaborates with suppliers throughout its supply chain to enhance emission modeling and data management.

The company's renewable energy and decarbonization journey is marked by several milestones. Notably, in 2022, AESC became the world's first battery manufacturer to achieve carbon neutrality across its global operations (Scope 1 and 2), certified by Carbon Trust. In that same year, AESC also launched the first carbon-neutral EV battery and followed up with a carbon-neutral energy storage battery in 2023.

Operational Optimizations and Collaborations

Throughout its global production network, AESC continuously optimizes its operations to lower energy consumption and carbon emissions. This includes a wide range of on-site energy efficiency improvements such as upgrading temperature and humidity control systems, installing smart sensors on production lines, and implementing waste heat and water reclamation strategies to minimize energy loss. AESC also collaborates closely with key suppliers to facilitate emission reductions throughout its value chain.

Through these strategic initiatives, AESC has established a practical and scalable decarbonization pathway for the global lithium battery industry. The CDP's A- rating reinforces AESC's reputation as a sustainability leader, as the company partners with clients and collaborators worldwide to advocate for a more sustainable battery ecosystem.
