Smart Mobile Devices (SMD)—including hardware devices, such as smartphones, tablets, and wearables; the software systems that animate them; and the data-communication infrastructure that connects them—pose increasing sustainability challenges due to their short lifespans, high resource demands, and growing e-waste. While Sustainable Product–Service Systems (S.PSS) have been applied in various sectors to support environmental goals, limited research has addressed their application in the context of SMD. This study aims to explore how S.PSS can be tailored to support sustainability in the SMD sector. For that, it combines a literature review with a multiple-case analysis of seventeen commercial offerings to develop a conceptual framework refined through six expert interviews. Cases were coded using the classical PSS typology and other sector-specific criteria and subsequently clustered in a polarity diagram to identify designable patterns, underpinning the conceptual framework. The study contributes an S.PSS-SMD framework comprising a sector-tailored classification and sixteen archetypal models, operationalized in an archetypal map with potential opportunities. Theoretically, the study offers a sector-grounded operationalization that extends S.PSS design theory to digital product–service ecosystems. It provides a strategic decision aid for designing business models, service bundles, stakeholder roles, and lifecycle responsibilities to pursue win–win environmental and economic sustainability.

Increasing consumer awareness on significant environmental challenges, in addition to forthcoming regulations, is driving domestic appliance manufacturers to adopt an Ecodesign approach to more effectively and significantly reduce the environmental impacts along all of the life cycle phases of their products, minimising energy and material consumption, optimising the life of the product, facilitating recycling, facilitating disassembly, optimising material conservation/renewability, and minimising toxicity. This paper emphasises and discusses the significance of supporting this process by creating a company-specific handbook of guidelines and checklists to design low-environmental-impact products across an entire company’s appliance range. Checklists are design support tools intended to qualitatively assess whether, and to what extent, an Ecodesign guideline has been applied, enabling the evaluation of existing products or newly developed concepts, while also serving to guide and inspire sustainable design decisions. It is argued that these are effective tools in translating eco-efficient design into practice and guiding the whole of product development organisation through a knowledge-based approach. The Handbook of Guidelines to Design Low Environmental Impact Products is the result of a project commissioned by a home appliance company to the LeNSlab (research group on Design and System Innovation for Sustainability) of the Design Department of Politecnico di Milano, elaborated, after preliminary desk research, through a series of activities, interactions, knowledge exchanges, and operative workshops in cooperation with the company team of experts. The handbook contains 7 Ecodesign strategies, 27 sub-strategies, 157 guidelines, and related checklists, to be specific to such a level that they can effectively be applied to all types of company appliances.

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.

The use of digital technologies in Product Service Systems (PSSs) has increased in recent years. More and more smart devices are used in these models, collecting significant amounts of data to provide personalized and responsive products and services. However, data extraction has been causing disruptions in the social sphere, manipulating users, threatening democratic processes, and harming the social dimension of sustainability. To mitigate these problems associated with user data, some solutions on the market claim to take a more ethical approach. This article presents the preliminary results of a study aiming to understand what features in these solutions may favour the resilience of democratic processes and reduction in user manipulation due to personal data extraction and personalized activity. It also examines how designers can use them to develop smart PSSs that incorporate these elements and features in their process. Based on a literature review, three key elements relevant to personal data and democracy were assessed and applied to analyze 30 cases. The results provided a preliminary list of 46 features and 15 strategies for designers to embed these elements in the design of smart PSSs, as well as a conceptual framework. The study concludes with recommendations for future research.

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.

This paper presents a review and critical analysis of papers submitted for the Ecosystems Track of the Life-Changing Design conference, which focused on "Changing Ecosystems" through design for sustainability. The conference track aimed to explore the multifaceted dimensions of sustainability and its connection to design practice, research, and education. The papers covered various subthemes, including products and product design, Sustainable Product-Service Systems, craft, materials, aesthetics, more-than-human design, biodesign, and the role of designers as actors in society influencing policy, local-global dynamics, place-making, strategy-setting, and stakeholder interactions. Through synthesising the findings and insights from these papers, this review aims to provide a comprehensive understanding of the advancements made in design for sustainability and highlight emerging trends and future research directions.

Recently, the ongoing digital transition has brought forth both new risks and opportunities for environmental sustainability. However, despite some attention given to potential relationships between related areas and a growing research interest therein, a limited number of studies have holistically explored the nexus between digital transition, PSS, and environmental benefits. This research is a systematic literature review focused on the relationship between S.PSS and environmental sustainability during the digital transition process. We propose a novel analytical perspective by synthesizing and mapping the existing literature to derive a potential pathway for digital technologies to optimize four S.PSS relevant factors through four primary approaches (Information/Data Access Optimization, Connectivity & Communication Optimization, Process Optimization, Systemic Optimization ), leading to environmental benefits across six dimensions (Product lifetime extension, Intensive use of Product, efficiency of resources, resources’ renewability, Material life extension and Pollution reduction), and outlining current shortcomings and suggested future research directions. This study identifies broad consensus on the potential significance of digital transition in contributing to the environmental benefits of the product design for environmental sustainability (i.e. Life Cycle Design), but reveals a scarcity of research focusing on other aspects of S.PSS (e.g. service and business model innovation) and environmental benefits (e.g. resource renewability), which need further investigation. This study assists researchers in comprehending the potential environmental impacts of digital technologies when applied to S.PSS, identifying future research priorities to inspire designers to revaluate the new role and competence of S.PSS in promoting sustainable transition in the digital era.

Effective product design strategies play a crucial role in promoting sustainable production, consumption, and disposal practices. In the literature, many such practices have been proposed by various researchers; however, it is challenging to understand which is more effective from the design point of view. This study employs bibliometric analysis and visualization software, CiteSpace, to comprehensively assess the literature on sustainable product design methods (SPDMs) from two major citation databases, namely, China National Knowledge Infrastructure and Web of Science, covering the period between 1999 and 2022. The objective of this review is to identify the latest research trends, progress, and disparities between China and the rest of the world in the field of SPDMs. The findings reveal that the development of SPDMs is characterized by a combination of multi-method integration and expansion, as well as qualitative and quantitative hybrids. However, research processes differ between China and other countries. Chinese studies focus on digital-driven development, rural revitalization, and system design, while research from other countries emphasizes a circular economy, distribution, additive manufacturing, and artificial intelligence. Nevertheless, both Chinese and international studies lack quantitative research methods in relation to socio-cultural sustainability. Future research should aim to deepen sustainable design methods and standards for specialized products, as well as to incorporate quantitative methods that address cultural and social sustainability dimensions. Open-source and shared SPDMs should be encouraged to promote methodological innovation that prioritizes multidimensional and systematic sustainable benefits, leveraging the strengths of new technologies.

Given the serious environmental impact of the furniture system, the role of design in innovating furniture products toward sustainability is increasingly recognized as a key leverage, as acknowledged by the European Union's Circular Economy Action Plan in 2020. The need for sustainable design knowledge to address environmental issues caused by the life cycle of furniture products-a fundamental part of the furniture system-has now been prioritized. Despite the fact that Life Cycle Design (LCD) is widely studied as a systematic approach that considers all life cycle stages and engages the objectives of reducing environmental impacts, its application within the furniture system is still very limited. Within this framework, the paper presents furniture-specific LCD guidelines to guide sustainable furniture design. These guidelines were developed through an established methodology involving scholars and specialists on both Design for Sustainability and Furniture Design, and were the results of a research project funded by the Italian Ministry of Education (MIUR), aimed at developing and disseminating innovative design strategies and guidelines to foster a sustainable and circular economy within the furniture industry. In this sense, these guidelines will promote long-term open innovation and technological transformation of furniture products, allowing designers and organizations to support the implementation of sustainable options from the beginning of the design process.
