The UmweltBank promises an "ecological product guarantee" which means, that the clients´ money will only be invested in environmentally sound projects at reasonable terms. Credits are mainly provided in the field of renewable energies as well as ecological building. Private clients receive an interest rates reduction for ecological aspects in their house building. Investments that are harmful to the environment and the social life, for example expenditures on nuclear power, arming industry or genetic science, are excluded from the banks support.

Since 25th of June in 2001 the UmweltBank PLC is noted on the Frankfurt Stock Exchange (bond number 557 080). At the time of the stock listing the bank expanded their rooms and moved to an ecologically done up arts nouveau building. This house, which is near to the existing offices, was erected in 1911 and is now under protection of works of arts. A documentation on the restoration steps with the building in Emilienstraße 3 was published in June 2003.
