Sustainable investing in the water sector - your impact investment with Tareno
Countering water scarcity
Water is the elixir of life on our planet – and an increasingly scarce resource. The growing demand for limited resources makes sustainable water systems one of the most pressing challenges of our time. With the Tareno Global Water Solutions Fund, you invest worldwide in companies that develop and market innovative products and technologies for the efficient use of water.
Our commitment to sustainable water investments
Our sustainable fund not only focuses on economic indicators, but also takes social and environmental aspects into account when selecting companies. The fund takes all three ESG criteria into account and combines economic success with responsible action. As a public fund, it offers you a sustainable investment with a long-term perspective.
Further information on our sustainability approach and the specific impact of our investments can be found in our annual sustainability report or on Tareno’s sustainable investment solutions page.

Impact share class: investing with a measurable impact
We have launched the Impact share class for all those who want to make a direct and measurable impact in addition to a sustainable investment in the water sector. This unique share class of the Tareno Global Water Solutions Fund gives investors the opportunity to participate directly in specific drinking water projects.
The focus is on projects that make a measurable contribution to SDG 6 “Clean water and sanitation”. The aim is to create long-term solutions by establishing local structures, involving the population and developing concepts for the maintenance and operation of the facilities.
How the impact share class of our water fund works
In the impact share class of the Tareno Global Water Solutions Fund, 25% of the management fee is donated to drinking water projects. These donations are used to finance projects worldwide that give people access to clean water.
The donation portion is borne jointly by the investors and Tareno: one third comes from the investors and two thirds from Tareno. Specifically, the management fee for the impact share class is only 0.075% higher than that of our normal share class for institutional investors. This additional contribution from investors is doubled by Tareno. A total of 25% of the management fee is donated.
What criteria do we use to select our impact partners?
We work with carefully selected partner organizations to implement drinking water projects. It is crucial that they have experience, local roots and transparent structures.
Important criteria are:

Which projects do we support?
The projects financed should have an impact where the need is particularly great. We therefore focus on regions where access to clean drinking water is limited or not sufficiently guaranteed.
When selecting projects, we pay particular attention to:
