Potential Analysis of Car Headlight Repair through Lens Replacement and its Implications for the CO₂e Footprint

The automotive industry set itself ambitious goals for net zero vehicles in around 15 years. First measures like requirements for secondary and low carbon materials are already in place but will leave big gaps towards the aimed near total reduction of emissions. The impact of service and aftermarket parts is usually neglected or underestimated in LCA studies although service parts are produced in high volumes. Highly complex parts such as automotive lights underline the need for consequent repair solutions. The study showcases the impact of ZKWs repairable solution for modern lights in combination with a medium size car fleet to quantify the positive impacts on the lifetime emissions of climate gases in a model-based approach. Improving repairability without compromising mechanical robustness is one puzzle piece to reach net zero industry goals.
