Sustainability comprises much more than environmental aspects. Social and economic sustainability are of equal importance. This was also the perception of those who drafted the sustainability guideline – the Hydropower Sustainability Assessment Protocol (HSAP) – which for some years now gives valuable guidance when evaluating hydro power projects and plants.


Example: Sustainability and hydro power

The time-honoured, over 90 years old, hydro power plant Walchensee at the base of the Bavarian Alps received outstanding results when being evaluated according to the Hydropower Sustainability Assessment Protocol.

By the way: The Hydropower Sustainability Assessment Protocol was developed and endorsed by all representatives of all relevant stakeholder groups, e.g. international NGOs, banks and governments.
