China’s Battery Makers Race To Meet EU Carbon Rules

Chinese battery makers are “piling into” zero-carbon industrial estates as Europe prepares to cap the emissions embedded in the batteries it imports, a defensive response that could become an exportable advantage in industrial carbon management, according to a report by Gavekal Technologies.

The European Union’s Battery Regulation will require electric-vehicle and industrial batteries sold in the bloc to carry a digital passport disclosing verified life cycle emissions from February 2027, with a binding carbon cap taking effect as early as 2028.

The zero-carbon industrial estates – designed to tie factories directly to renewable power and operate under strict site-wide CO2 caps – are seen by Chinese battery makers as a route to easier compliance, according to the report published this week.

While the estates began as part of China’s domestic climate push, the EU’s carbon rules are the real force behind their sudden popularity, according to the report.

Policymakers in China have repeatedly cited the bloc’s carbon rules as “drivers of the country’s industrial decarbonisation efforts”, it said. 

A National Development and Reform Commission document last year listed adaptation to green trade rules as one of the five objectives of the country’s initiative to build zero-carbon industrial estates.

Battery, electric-vehicle and energy-storage projects account for 79 of the announced projects in the 52 pilot estates, far exceeding traditional sectors such as steel and aluminium, which only have 19 projects.

The EU is China’s largest battery export market, taking nearly 40 per cent of shipments in 2025, while Chinese firms supplied about 90 per cent of the bloc’s lithium-ion battery imports from outside the region that year, according to the report.

Contemporary Amperex Technology Ltd (CATL), the world’s largest battery maker, leads with nine announced projects, followed by Eve Energy with four and BYD with three. CATL began tracking embedded carbon emissions through the Global Battery Alliance’s battery passport system in 2024, well ahead of the EU’s 2027 deadline.

For CATL, the industrial estates are part of its broader strategy alongside building capacity inside Europe, according to the report. The estates’ direct renewable link matches the EU’s focus on physical electricity supplies rather than tradeable green certificates.

The significance of the estates could extend beyond compliance, the report argued. If the model works, Chinese firms could export not just solar panels and batteries, but also the expertise to build renewable-powered industrial estates.

“The strongest export potential is likely to be in emerging markets that already import significant volumes of Chinese solar, energy-storage and grid technology, making countries such as Pakistan, the Philippines and Chile plausible candidates,” said AJ Cortese, the report’s author.

Many factories in such markets already struggle with unreliable grids, creating demand for systems that can run on local renewable power.

The estates could also advance Beijing’s “green compute” ambitions. The report identified 31 artificial intelligence, cloud and data-centre projects whose steady demand could help absorb surplus wind and solar power.

For now, zero-carbon industrial estates still face several challenges. One bottleneck is China’s power grid: much of the wind and solar power generated in the country’s northwest and north cannot be transmitted to demand centres in the east because of limited grid capacity, according to a recent Global Energy Monitor report.

“Its viability should become clearer over the next few years, and certainly by 2030,” Cortese said. A strategy shaped by both domestic climate targets and European trade rules could yet become one of China’s next exports.
