Today, car bodies are not explicitly optimised for CO_2e_, only 50% of input material is utilised and most high-grade materials are downcycled at end-of-life. **Solution and impact** We will develop digital tools and net-zero enabling technology for designers to lock-in materially efficient decisions early in the vehicle development process reducing body structure emissions by 75% whilst reducing timescales and boosting cost competitiveness, aligning with UK sustainability strategy.
