In 2015, European Aluminium and the International Aluminium Institute (IAI) developed a tool to compare the impact of different lightweighting solutions in terms of their net greenhouse gas (GHG) emissions over the full vehicle lifecycle. The tool includes Full Electric Vehicles (FEVs) and Plug in Hybrid Electric Vehicles (PHEVs) as well as conventional vehicles. The model allows the user to simulate lightweighting of different types of vehicles taking the grid mix in individual countries into account.
Different materials have different potentials in reducing the weight of the vehicles and also different carbon footprints for production and recycling. To make a valid and fair comparison between different materials, the full life cycle has to be taken into account. This model gives the user the possibility to compare a baseline car with two lightweight versions. The lightweighting can be achieved either by using different types of Aluminium solutions or by using Advanced High Strength Steel (AHSS).
In this 2019 revision of the model, new LCI datasets covering different regions around the world have been included. The model has also been updated with new use phase data from the IFEU study published in 2016. To simplify for the user, some case studies have been included.
