As awareness of the serious environmental impact of the furniture sector increases, design is increasingly recognized as a crucial lever for innovating towards sustainable furniture products. This acknowledgment was emphasized by the European Union in the Circular Economy Action Plan in 2020 and is further emphasized in the forthcoming Ecodesign for Sustainable Products Regulation in 2024. To address the environmental issues stemming from the life cycle of furniture products, which constitute the fundamental part of the furniture system, specific design knowledge and know-how are developed within this study. Although Life Cycle Design (LCD) is a systematic approach to reducing environmental impacts, its application within the furniture system remains limited. This paper adopts a design-based research approach with three research stages and employs various methods including a literature review, case study, workshops, interviews, questionnaires, and a focus group to develop furniture-specific LCD guidelines and a toolkit. As a result, this paper presents furniture-specific LCD guidelines (comprising 7 strategies, 21 sub-strategies, and 154 guidelines), 41 environmentally sustainable furniture case cards, and a toolkit (comprising 4 tools). These guidelines provide comprehensive principles for designers to address environmental impact throughout the furniture’s life cycle. The toolkit guides sustainable furniture LCD, promoting low environmental impact and high design efficiency. These outcomes address the existing gaps in knowledge and tools in this field.

Historically, the reaction of humankind to environmental degradation, especially since the second half of the last century, has moved from an end-of-pipe approach to actions increasingly aimed at prevention.

In the previous chapter, we introduced that Distributed Renewable Energy (DRE) is the most promising model to bring sustainable energy to All.

The world is facing a strong evolution due to the advancement of information and communication technologies that set the knowledge technologies at the base of productivity, competition and power.

A key contemporary query is the following: within the current social, environmental and economic crisis, which are the opportunities for innovate towards sustainability? Do we know any offer/business model capable of creating (new) value, decoupling it from material and energy consumption? In other words, is there any alternative to significantly reduce the environmental impact of traditional production/consumption systems?

Furniture is a crucial sector for sustainable development due to its high environmental impact and substantial potential for sustainable improvement. Despite many existing furniture Life Cycle Assessment (LCA), they often provide fragmented data, hindering a comprehensive understanding of the environmental impact across different furniture groups due to methodological disparities. This study employs LCA as the primary method to evaluate 25 furniture pieces across 8 groups. Using the Environmental Footprint method and the Ecoinvent 3.7 database within Simapro 9.1.1.1 software, it generates a comprehensive database with all 25 furniture pieces’ environmental performance data, including the environmental impacts of furniture with different characteristics within the same furniture group, the impacts of various life cycle stages for each piece, and the impacts of different materials/processes within each stage. The database highlights several trends: furniture groups with higher material weight generally exhibit greater environmental impact; the pre-production stage generally has the highest impact, followed by the production, distribution, end-of-life and use stage. For environmental data interpretation, the study provides valuable design priorities, suggestions, and opportunities for improving the environmental performance, supported by case studies. By uncovering common trends, this research informs and guide the pursuit of more sustainable furniture design and production practices.
