Der Gedanke der Nachhaltigkeit verbindet wirtschaftliche Leistungsfähigkeit
The concept of sustainability combines commercial
profitability with ecological responsibility and social
justice. These three goals necessitate each other.
Continuous economical growth can not be achieved by
means of ongoing overexploitation or social injustice.
Our responsibility for the present but also for future
generations is based on this knowledge.
Angela Merkel, 2011
