Life Cycle Engineering (LCE) analyses the potential ecological, economic, technological, and social influence of products, processes, and services over their whole life cycle. This multidimensional approach ensures that all significant factors are evaluated within a sustainable decision process. The methodology of Life Cycle Engineering presents the results in a readily comprehensible manner, thereby ensuring maximum transparency – a good basis for decision making. Life Cycle Engineering combines various methods to depict the ecological, economic, technological, and social influence of a product or a service.
