China's CATL joins hands with BMW, Renault, and other automakers to lead the standardization of the battery circular economy

Battery manufacturer CATL launched a global alliance with global automakers including Xiaomi, BMW, Renault, and Volvo to standardize the battery circular economy at London Climate Action Week. London Climate Action Week is Europe's largest independent climate event held annually in London, UK, in June, where more than 75,000 participants discuss multilateral climate diplomacy and the realization of global carbon neutrality.

This cooperation, centered on CATL, was launched to build a structured development pathway for battery asset management and vehicle lifecycle regulations. The alliance has begun developing a "Battery Circular Design Guide" with the goal of full public release by 2027. The guidelines will introduce unified technical standards for diagnostic testing of battery cells, simplification of pack disassembly, and cell remanufacturing. These technical parameters will define structural evaluation metrics applicable to both passenger electric vehicles and large commercial logistics vehicles.

The alliance focuses on expanding standardized practices by evaluating parameters such as battery cell operating history, degradation rate, and remaining lifespan. Once unified lifecycle rules are established, automakers and vehicle operators will be able to accurately calculate asset values and manage financial allocation risks. The Ellen MacArthur Foundation coordinates cross-industry collaboration and aligns corporate strategies with carbon reduction goals.

Supply chain emissions from mining and raw material processing are five times higher than those from core factory operations. To address this issue, CATL reduced the carbon intensity of materials by 32% by utilizing recycled components. Its subsidiary Brunp processed 210,000 tons of battery waste in 2025, recovering 99.6% of key minerals.

CATL has also selected Octopus Energy as a partner to build a commercial vehicle network in Europe. This is part of establishing a large truck battery swapping system in Europe. The new project utilizes engineering technologies validated in a 1,250-kilometer medium-sized battery swapping corridor deployed on domestic Chinese transport routes last year.

According to operational tracking, core factory emission intensity has decreased by 77% through 1,000 efficiency projects since 2022. Based on this, CATL achieved core operational carbon neutrality across all its battery manufacturing facilities last year. Standardized emission reductions will ensure that future battery exports fully align with Western environmental regulations.

Meanwhile, South Korea's National Climate Crisis Response Committee (hereinafter Climate Response Committee) under the direct supervision of the London Climate Action Week Joo Gan-e (President) was attended by Lee Chang-hoon Gong Dong-wi (Director).
