The PROSA SLCA

SLCA is one of the core tools used within PROSA. In the course of implementation, care must be taken to coordinate the key parameters with LCA and Life-Cycle Costing (cf. Integration Checklist). It is possible, however, to carry out SLCA as a free-standing analysis or in combination with (either) LCA or Life-Cycle Costing.

Social aspects are investigated throughout the product life cycle and system, normally in comparison to some alternative. Stakeholders should be involved as far as possible (cf. “Stakeholder Involvement” Table ). The methodological procedure corresponds to that for the life-cycle assessment (LCA) and is carried out in four steps.


1. Goal and scope definition

2. Life-cycle inventory (LCI)

3. Life-cycle impact assessment (LCIA)

4. Interpretation of results
