Water - a sustainable investment

Invest sustainably, invest in water
Water is the elixir of life on our planet and for this reason a valuable raw material. However, due to increasing demand and constant supply, this precious commodity is becoming increasingly scarce. The Tareno Global Water Solutions Fund invests worldwide in companies that develop and produce commercialised products and technologies for a more sustainable and efficient use of water. The positioning of these companies with regard to social and environmental issues play also a decisive factor in the selection process.
