However, when comparing different life cycle analyses with one another, in order to identify the most sustainable way forward, it is crucial that equivalent data are available for both products and processes in question. In other words, do not try to compare apples with oranges. If one product has a much higher availability of data, it cannot be justly compared to another product which has less detailed data. The result of doing so would be drawing incorrect conclusions that would defeat the purpose of conducting an LCA in the first place.
If you as an automotive engineer are interested in seeing the full life cycle of a vehicle, you can use an excellent tool called Automotive Energy & GHG Model (“UCSB Model”). The model, developed by the University of California at Santa Barbara, helps users to analyze the environmental impact of new vehicle designs using the Life Cycle Assessment (LCA). Get it here.

As an example of one way to reduce CO2, we look to steel. The image below shows that steel has an advantage compared to some other lightweight materials as it emits less CO2 when being produced. However, there is also a difference between steels. SSAB has one of the cleanest steel manufacturing processes in the world and by using advanced or ultra high strength steel, you can further reduce emissions, as you will be using less steel.
