More than 10 years ago, Carbotech accompanied the development department of Schindler in the preparation of an ecobalance of a typical lift system. The findings of this study have been incorporated into the development of the new lift systems. The current life cycle assessment carried out by Carbotech has shown that the environmental impact per average lift use could be halved within these years. In addition, the evaluations show the relevance of the individual life cycle phases from the provision of raw materials through lift operation to disposal and also enable conclusions to be drawn about their optimisation potential. For the ecological evaluation of measures and for analyses of different lift configurations, a special software tool for the analysis of lift configurations was developed. This tool helps Schindler to continue to take ecological aspects into account in development. It also forms the basis for communicating the environmental impact of the various Schindler lift systems.
