This study used a sample of 2,917 participants across four different European regions (France, Spain, Czech Republic and Benelux). The aim of the study was to analyse whether lifespan labelling on products might influence consumers' purchasing decisions. The results of the test show that lifespan labelling has an influence on purchasing decisions in favour of products with longer lifespans. On average, sales of products with a label showing a longer lifespan than competing products increased by 13.8%. Several different ways of displaying this information were tested. An experiment was designed to test the potential influence of lifespan labelling. The experiment was based on simulated online shopping and involved designing a dummy retail website. We tested the effects of this labelling on nine product categories (suitcase, printer, coffee maker, vacuum cleaner, smartphone, trousers, sport shoes, television, washing machine). Participants could choose between 10 different models for each product category (e.g. 10 different coffee makers). Participants were able to navigate through the site in order to make their selection, like in a real online shop. Once they had confirmed their shopping basket, participants were redirected to a questionnaire, which measured socio-economic indicators as well as psychosocial variables. Differentiated analyses were performed on nine categories of product, four label formats, ranges of purchase prices, and participants' country of residence. The study The Influence of Lifespan Labelling on Consumers) was commissioned by the European Economic and Social Committee (EESC) to a research consortium composed of the SIRCOME research to action agency, the University of South Brittany and the University of South Bohemia on behalf of the (Ref: CES/CSS/1/2015).
