1. A method for operating a motor vehicle with an internal combustion engine comprising a combustion engine and an exhaust line with an exhaust aftertreatment system, the method comprising:
determining at least one environmental emission of at least one exhaust component contained in exhaust gas generated by the combustion engine;
limiting operation of the internal combustion engine with respect to a deliverable power when a limitation threshold value for the at least one environmental emission of the at least one exhaust component is exceeded; and
if triggering a warning message and/or adapting the operation of the internal combustion engine in a power-neutral manner, such that the at least one environmental emission is reduced, when a warning threshold value for the at least one environmental emission of the at least one exhaust component is exceeded, wherein the warning threshold value is lower than the limitation threshold value.
