Sharing household products for a sustainable environment: A city diagnostic
Doktorsavhandling, 2025

The Sharing Economy (SE) has emerged as a potential pathway to sustainable consumption in cities, allowing households to replace their purchases of newly manufactured products and reduce their material, energy, and emissions impacts, among others. However, as the research field expands, it becomes clear that sharing can only be environmentally sustainable under specific circumstances. To address essential gaps in understanding whether the SE can hold its promise, particularly for household products, this thesis aims to advance knowledge on the environmental sustainability potential of sharing household products in an urban context. Taking Gothenburg, Sweden, as a case, the research focuses on three questions: (1) What factors influence whether sharing household products is more environmentally sustainable than purchasing new products?, (2) In which ways can consumption reduction play a role in the environmental sustainability of sharing household products?, and (3) What is the potential of different geographic areas, demographic groups, and product groups to achieve sustainable outcomes through sharing?. The mixed-methods research design involved a literature review, qualitative coding, statistical analysis of questionnaire survey data, quantification of household consumption amounts with an extrapolation method, spatial analyses, and collaboration with the local government. The analysis reveals (1) 29 factors before, during, and after sharing that influence the sustainability outcomes of sharing. In particular, (2) consumption-reduction factors play a crucial role, often depending on consumer behavior and competing with transport and energy impacts, and (3) varying levels of potential were observed for different geographic areas, such as the inner and outer city, various demographic groups regarding gender, age, and education level, and for the product groups of clothes, tools, and hobby equipment. The variations were shaped by each group’s levels of product consumption and ownership, attitudes toward sharing, and accessibility to different types of sharing initiatives. These results can provide actionable insights for local governments, practitioners, and households to leverage the SE as a sustainable tool while contributing to reducing fragmentation in the literature, particularly concerning the environmental sustainability potential of sharing household products.

Kan delning av hushållsprodukter göra städer mer hållbara?
 
Denna avhandling utforskar den frågan genom att studera delningsekonomin i Göteborg, Sverige. Delningsinitiativ, som verktygsbibliotek eller klädbyten, kan minska behovet av att köpa nya produkter, vilket sparar material, energi och utsläpp av växthusgaser. Men delning är inte alltid mer miljövänligt. Avhandlingen identifierar 29 nyckelfaktorer som påverkar om delning verkligen är hållbar, från hur människor använder och transporterar delade föremål, till deras konsumtionsmönster före och efter delning. Den visar också att möjligheten att dela på ett hållbart sätt varierar beroende på var människor bor, vilka de är och vilka föremål som delas. Till exempel har innerstadsbor i Göteborg och personer med högre utbildning bättre tillgång till delningsalternativ och är mer öppna för att minska sin konsumtion. Dessutom har produkter som kläder och verktyg har stor potential men saknar möjligheter att delas på ett hållbart sätt. Studien kombinerar enkäter, statistisk och rumslig analys samt samarbete med Göteborgs kommun för att kartlägga var och hur delning kan göra störst skillnad. Resultaten erbjuder praktisk vägledning för städer, organisationer och användare som vill göra delning till ett verkligt verktyg för miljömässig hållbarhet.

Can sharing household items help cities become more sustainable?
 
This thesis explores that question by studying the sharing economy in Gothenburg, Sweden. Sharing initiatives, like tool libraries or clothing swaps, can reduce the need to buy new products, saving materials, energy, and greenhouse gas emissions. But sharing isn’t always greener. The thesis identifies 29 key factors that influence whether sharing is truly sustainable, from how people use and transport shared items, to their purchases before and after sharing. It also shows that the potential to share sustainably varies depending on where people live, who they are, and what items they share. For example, Gothenburg’s inner-city residents and people with higher education levels have better access to sharing options and are more open to reducing consumption. Additionally, products as clothes and tools have great potential but lack opportunities to be shared sustainably. The study combines surveys, statistical and spatial analysis, and collaboration with Gothenburg’s local government to map out where and how sharing can make the biggest difference. The findings offer practical guidance for cities, organizations, and users aiming to make sharing a real tool for environmental sustainability.
