Abstract: A software application providing system and methods for using Web Services to connect an Analysis calculator, a Recommendations engine, Social Networking, and Knowledge Management technologies in a platform for operationalizing sustainability into Product Life Cycle Management (e.g., conception, design, manufacture, service, end-of-life disposition) and Enterprise Resource Planning (ERP) (including enterprise-wide activities of manufacturing, supply change management, financials, human resources, customer relationship management, and external stakeholder engagement). A Web Service Framework integrates Life Cycle Assessment (LCA) software technology with product design, manufacturing, and distribution process design tools. A logic layer can perform sustainability estimates within a Knowledge Management System. A Web Service Framework is utilized for constructing or entering LCA models, methodologies and source data.
