A systemic view on sustainable consumption

Sustainable product-service system (PSS) has potentiality to reduce the environmental stress through dematerialization of economy based on function-based well-being. PSS (also called as service) is a type of human-activity system with a series of events and is produced only after the demand from a consumer. The features of the events influence the consumer to act rationally according to the particular situations. Consumers must have freedom to choose a combination of relieving and enabling model of PSS to act rationally upon those according to the feature of events and the consumers have reasons to value their selection of services. A case of a complete journey of a passenger with urban mobility services is considered to visualize and realize the rational behaviour, which shows a systemic pattern and also autopoietic in nature.
