Life Cycle Engineering as a Pathway to Achieving Net-zero Targets

Abstract

Life cycle engineering (LCE) was introduced in the early 1990s with a focus on eco-efficiency, hence designing products to reduce the environmental impact over their life cycle while maintaining or increasing the value created. In the meantime, the world has seen the emergence of a climate crisis and a biodiversity crisis despite significant eco-efficiency improvements of individual products and services over the years, highlighting the gap between bottom-up LCE activities and top-down sustainability concepts such as planetary boundaries and net-zero targets for climate change.This paper presents a structured LCE approach for practitioners, supporting life cycle engineering of product life cycles with an absolute sustainability perspective towards achieving net-zero targets. An industrial case is provided to demonstrate the applicability of the methodology.
