Life-cycle engineering

Résumé
Life-cycle engineering (LCE) is a sustainability-oriented engineering methodology that takes into account the comprehensive technical, environmental, and economic impacts of decisions within the product life cycle. Alternatively it can be defined as “sustainability-oriented product development activities within the scope of one to several product life cycles.” LCE requires analysis to quantify sustainability, setting appropriate targets for environmental impact. The application of complementary methodologies and technologies enables engineers to apply LCE to fulfill environmental objectives. LCE was first introduced in the 1980s as a bottom-up engineering approach, and widely adopted in the 1990s as a systematic ‘cradle-to-grave’ approach. The goal of LCE is to find the best possible compromise in product engineering to meet the needs of society while minimizing environmental impacts.  The methodology is closely related to, and overlaps with, life-cycle assessment (LCA) to assess envi
