Life cycle engineering of new products and technologies must consider not just the single product and product life cycle, but also the foreseeable growth in market volume that results from increases in population and affluence, in order to allow the associated total environmental impact to be taken into account during the product development. The emphasis should not only be on eco-efficiency but also in eco-effectiveness. In the context, eco-effectiveness provides the target (e.g., 2050 targets), while ecoefficiency provides a progressive pathway to get there. The main aim of this special issue is to create a platform for researchers around the world in the area of Life Cycle Engineering and Sustainable Manufacturing for achieving net-zero targets and environmental sustainability.

新产品和新技术的生命周期工程不仅要考虑单个产品和产品的生命周期，还要考虑由于人口和富裕程度的增加而导致的市场容量的可预见增长，以便考虑相关的总体环境影响产品开发过程中的帐户。不仅要强调生态效率，还要强调生态效益。在上下文中，生态效率提供了目标（例如，2050 年目标），而生态效率提供了实现目标的渐进途径。本期特刊的主要目的是为全球生命周期工程和可持续制造领域的研究人员创建一个平台，以实现净零目标和环境可持续性。
