The sustainable product-service system (SPSS) concept highlights that achieving sustainability requires changes in both ‘production’ and ‘consumption’. Nevertheless, attention has focused mainly on ‘production’. This paper enriches the SPSS approach with insights from the sociology of consumption and practice theory to provide a deeper understanding of the use of products and services in daily life contexts. The paper advances three key insights related to: a) the internal dynamics of user practices, b) the strength of linkages of practice elements (loose and tight coupling), c) external linkages to other practices. These insights are mobilised to provide a deeper understanding of the uptake and diffusion of innovations such as SPSS. The insights are illustrated with two cases in which interventions designed to stimulate diffusion have had differential success: energy efficient light bulbs and low temperature laundry. Implications for understanding the diffusion of SPSS are discussed. [ABSTRACT FROM AUTHOR]

Abstract Degrowth—the reduction of energy and material throughput via shrinking total economic production and consumption in a socially sustainable way—would entail fewer working hours. However, work time reduction is not a sufficient condition for lower throughput because people may engage in environmentally harmful activities during expanded leisure. The purpose of this paper is to revisit the pessimistic and critical traditions to explicate unconventional utopian images of inactivity as a valuable feature of a better society. Pessimism makes a case for renouncing dissatisfaction-causing desires, an ethic that takes on a collective and futuristic form in Eduard von Hartmann and Emil Cioran. In the critical tradition, an indirect foundation of degrowth thinking, the central goal of the abolition of alienated labor is elevated to utopian heights in Theodor W. Adorno's brief portrayal of peace as humanity reconciled with nature in rest. These forecasts and hopes help envision what aspects of leisure may look like in post-growth society. For example, work time reduction policies should be paired with consumption-curbing policies, especially advertising limits. I warn against recuperation via "minimalist" commodities. Readers interested in degrowth and sustainability will benefit from contributions to discussions surrounding work time reduction, sustainable consumption, and post-growth imaginaries. Highlights • Work time reduction is not a sufficient condition for degrowth. • Increased inactivity is an underexplored form of low-impact leisure. • Pessimism and critical theory help visualize an idler society. • The argument is formulated as resignation from desire in the pessimistic tradition. • Critical theory envisions reconciliation, perpetual peace in a post-work society.
