5 Results of the Life Cycle Assessment
Comparison of Life Cycle Impacts
On the basis of the Life Cycle Inventory data, Life Cycle Impact Assessments are drawn
up for all the environmental impact categories. The interactions of all the emissions
recorded are considered and potential environmental impacts are determined based
on scientific models (see Fig. 3).
Diesel vehicles
With reference to average impact per inhabitant in the EU, Fig. 13 clearly shows that
all the vehicles considered here make their largest contributions to overall environmental
impacts in the global warming potential category, followed by acidification
and photochemical ozone creation. Contributions to the categories eutrophication
and ozone depletion potential are smaller. Consequently, the notes below focus on
the first three environmental impact categories.
