Die umweltökonomische Literatur bedient sich seit geraumer Zeit des Begriffs Öko-Effizienz, um das Wirtschaften mit ökologischen Ressourcen zu charakterisieren. Allerdings muss konstatiert werden, dass sich noch keine herrschende Meinung über den genauen Begriffsinhalt herausgebildet hat. Dies war Anlass für das Kompetenzzentrum Environmental Performance Measurement der TU Dresden, existierende Definitionen in der umweltökonomischen Literatur und der betrieblichen Praxis zusammenzutragen und um eine Expertenbefragung zu ergänzen. Darüber hinaus wurden die Normen der ISO 14000er-Reihe sowie die EG-Öko-Audit-Verordnung im Hinblick auf den Gebrauch des Begriffs Öko-Effizienz untersucht. Den Kernpunkt dieses Diskussionspapiers stellt dabei die Auswertung der Expertenbefragung dar.

The primary objective of this work was to analyse how water companies are affected by climate change and how they try to adapt to it. Therefore, a systematic literature review was being accomplished. The work is being divided into a theoretical and a methodological part. First of all an overview of the climatic changes that are projected to occur during the next years is being given. Then, resulting impacts on the water cycle are being pointed out. Furthermore, raw water sources, water companies obtain water from are being defined as well as the treatment process. Within the methodological part the approach of a systematic literature review is being applied, which includes the selection of references as well as their evaluation. The results of the literature review are that concerning the effects of climate change on water companies, the risks water providers might face, clearly predominate possible opportunities. Especially the deterioration of the raw water quality caused by increasing temperatures, floods as well as heavy rainfalls can be seen as a serious problem. Moreover, the most often mentioned adaptation strategies are dealing with quantitative water problems such as measures to increase storage as well as treatment capacity or leakage reductions. All in all it can be stated that there is still uncertainty about how climate change is going to effect water companies, especially concerning water quality changes and the treatment process.
