We take the pollutant emissions of our vehicles into consideration at an early stage of the development process, and we embed the corresponding specifications in the documentation of this process. These specifications define particular characteristics and target values — for pollutant emissions, for example — that must be achie- ved for every vehicle model and every engine variant. We also use these target values to assess the milestones we reach in the course of product development. To do that, we compare the current status of a project with the target values and take corrective measures if necessary.
