AESC Achieves A- Rating from CDP for Climate Change Leadership

In a significant achievement for sustainability in technology, AESC, the world leader in battery technology for electric vehicles and energy storage, has been awarded an A- rating by the CDP (formerly the Carbon Disclosure Project) in the climate change category. This recognition is notable as it represents the highest score attained by any lithium battery manufacturer globally in the 2025 reporting cycle. AESC's robust efforts in sustainable battery production have set a new benchmark in the industry.

Commitment to Sustainability

AESC's A- rating reflects its strong and transparent carbon management framework, as well as continuous progress in the decarbonization of its battery production. By aligning its operational practices with stringent environmental standards, AESC integrates emission reduction targets into its everyday business decisions. The company has successfully developed capabilities in carbon footprint management, renewable energy adoption, and industrial decarbonization.

The rigorous standards applied by CDP evaluate over 22,100 companies worldwide, with only 10% achieving an A- rating or above. As a recognized leader in this initiative, AESC is paving the way for others in the industry to follow suit.

Innovative Practices in Carbon Management

AESC’s approach to carbon footprint management is comprehensive. The company adheres to the EU Battery Regulation and other international compliance requirements, establishing a systematic carbon footprint management framework. It has developed a corporate-wide emissions factor database based on internationally recognized methodologies and collaborated closely with suppliers to enhance carbon data modeling and management.

In terms of renewable energy and decarbonization, AESC has reached significant milestones. In 2022, it became the first battery manufacturer globally to achieve carbon neutrality across its operations (Scope 1 and 2), verified by Carbon Trust. That same year, AESC launched the industry's first carbon-neutral electric vehicle battery and followed up with a carbon-neutral energy storage battery in 2023. Through its global manufacturing network, AESC continues to optimize operations to reduce energy consumption and carbon emissions, implementing energy-saving measures such as improved temperature and humidity control in production lines, utilizing smart sensors, and reusing residual heat and water to minimize energy waste.

Collaboration for Sustainable Solutions

Furthermore, AESC works collaboratively with primary suppliers to drive emission reductions throughout the value chain. This joint effort has enabled the company to develop a practical and scalable decarbonization strategy for the global lithium battery industry. With its A- rating from CDP, AESC further solidifies its position as a sustainability leader, engaging with clients and partners worldwide to foster a more sustainable battery ecosystem.
