Beyond the factory floor: what really drives a battery’s carbon footprint
A new GIGABAT info-pack shares early life cycle assessment findings and practical recommendations for low-impact battery manufacturing
Cleaner electricity in the gigafactory matters, but it is only part of the story. The new GIGABAT info-pack on Life Cycle Assessment (LCA) shows that the biggest levers for greener batteries are often found upstream in raw materials, and downstream in pack design, recycling and battery lifetime.
The document presents the first results of the project’s screening LCA of its two reference chemistries, NMC811 and LFP. Their overall climate impacts turned out to be similar, but the main hotspots differ from one chemistry to the other. For both, raw materials weigh more than the energy used in the gigafactory, which plays a significant but not a dominant role.
Some findings may surprise readers: pack design can shift the comparison between chemistries: at high cell-to-pack ratios, LFP outperformed NMC811. The electricity used to charge a battery over its lifetime can also matter as much as, or more than, the impact of producing it.
The info-pack translates these insights into six practical recommendations, from prioritising high-impact materials and supplier-specific data to designing for recycling from the start. It also outlines the next step: a full LCA of GIGABAT’s production and recycling processes, aligned with the project’s digital twin and battery passport work.
Written for battery and cell manufacturers, gigafactory technicians, sustainability specialists, researchers and policymakers, it offers a concise, evidence-based look at what it takes to build low-impact batteries in Europe.
