Battery Maker AESC Tops Climate Rankings Worldwide

The batteries powering tomorrow's clean cars just got a whole lot cleaner themselves.

AESC, a global leader in electric vehicle and energy storage batteries, earned an A- rating from CDP for climate action in 2025. That's the highest score achieved by any lithium battery manufacturer worldwide.

CDP runs one of the world's most trusted environmental disclosure systems, evaluating how companies manage their carbon footprints. Out of more than 22,100 companies assessed this cycle, only 10% reached A- or higher.

The recognition validates AESC's comprehensive approach to carbon management. The company doesn't just talk about sustainability. It weaves emissions reduction into every business decision and daily operation across its global facilities.

AESC became the world's first battery manufacturer to achieve carbon neutrality across its operations back in 2022, verified by the Carbon Trust. The company followed that milestone by launching the industry's first carbon-neutral EV battery in 2022 and carbon-neutral energy storage battery in 2023.

The company's manufacturing facilities showcase practical innovation in action. Smart sensors on production lines monitor energy use in real time, while upgraded temperature and humidity controls minimize waste. Leftover heat and water get recycled rather than discarded.

AESC also built an enterprise-wide emissions tracking system that meets EU Battery Regulation standards. The company works directly with suppliers to strengthen carbon data collection and management throughout the supply chain.

The Ripple Effect

AESC's success proves sustainable battery manufacturing isn't just possible. It's achievable right now with existing technology and smart operational changes.

As electric vehicles become more common, ensuring the batteries inside them are made responsibly becomes crucial. AESC's approach offers a roadmap other manufacturers can follow, accelerating the entire industry's transition to cleaner production.

The company's partnership-focused strategy extends beyond its own walls. By collaborating with suppliers on emissions reduction, AESC multiplies its environmental impact across the entire battery ecosystem.

This recognition arrives at a perfect moment, as automakers and energy storage providers seek partners committed to genuine sustainability throughout their supply chains.

One company's A- rating just lit the way toward truly green batteries for everyone.
