European Aluminium calls on EU institutions to include low-carbon aluminium credits—alongside those for low-carbon steel—within the CO₂ standards for cars regulation. Aluminium and steel are both used in significant volumes in vehicles and are largely substitutable in many applications. Limiting credits to low-carbon steel alone risks creating an uneven playing field between materials and incentivising suboptimal component choices. Including low-carbon aluminium in the scope of the regulation is therefore essential for strategic, technological and sustainability reasons.
