For the world's largest battery production site, rapid expansion brought a major challenge: rising carbon emissions, high energy use and an increasing value-chain carbon footprint and manufacturing costs. To solve this, the site combined an AI-driven energy transformation, micro-grid photo-voltaic storage, process innovation and low-carbon product R&D. The initiative resulted in a 56% reduction in carbon footprint and helped 13 suppliers achieve carbon neutrality certification, cutting annual Scope 1 & 2 emissions by 16% and Scope 3 emissions per unit output by 45%.
