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.

生命周期工程是实现净零目标的途径
生命周期工程(LCE)是 20 世纪 90 年代初提出的,其重点是生态效益,即在设计产品时减少其在生命周期内对环境的影响,同时保持或增加所创造的价值。与此同时,尽管多年来个别产品和服务的生态效益有了显著提高,但全球却出现了气候危机和生物多样性危机,这凸显了自下而上的 LCE 活动与自上而下的可持续发展概念(如地球边界和气候变化净零目标)之间的差距。本文为从业人员介绍了一种结构化的 LCE 方法,从绝对可持续发展的角度支持产品生命周期的生命周期工程,以实现净零目标。本文提供了一个工业案例,以证明该方法的适用性。
