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
