Car makers consume large amounts of raw materials, and a conscientious planning of the manufacturing process is essential to the careful management of these resources. Among the most used materials in cars are lightweight elements such as aluminum, polymers, and to a lesser extent other metals (copper, titanium, platinum group, silicon, zinc, magnesium) elastomers, fluids, lithium, light rare earth elements.

For the denominator, the methodology applied to calculate the data in the table above is based on the incoming weight of materials and components in our warehouses. This data is the same as the one used for the calculation of the Scope 3 GHG emissions, category 4.1. The numerator is calculated based on supplier information provided through the International Material Data System. To estimate the quantity of packaging, we used the outflow quantity and assumed it was equal to the inflow quantity.
