In the recent past, environmental innovations have led to a considerable reduction of many pollutants; however, further innovation is required to tackle remaining pollution sources. This work analyses the significance and the effects of framework conditions on innovation activities that contribute to the realisation of a sustainable development. The book links the experiences of different research projects with the aim to develop a system of indicators to evaluate sustainable effects of (environmental) innovations. A comprehensive framework for an indicator system is established that allows to include different environmental innovation fields such as process innovations in the steel production, substitution of dangerous chemicals, organisational innovations in the field of waste disposal or sustainable water management.
