Using life cycle assessment, the study compares the global warming potential (GWP) of five ownership and end-of-life scenarios for creating and using a pair of jeans. The scenarios are as follows: (a) BASE, i.e. basic use with waste disposal; (b) REDUCE, i.e. extended use; (c) REUSE, i.e. reselling; (d) RECYCLE, i.e. industrial processing into new raw materials; and (e) SHARE, i.e. a rental service. Our results show that the lowest global warming impacts are achieved in the REDUCE scenario, and the second lowest are achieved in the REUSE scenario. The RECYCLE scenario leads to relatively high overall emissions because the replaced emissions from cotton production are relatively low. The use of rental services is likely to increase customers’ mobility, and if that happens in a large scale, then the SHARE scenario has the highest GWP. It was found that many new CE innovations come with a high rebound risk, and existing practices carry similar, yet smaller risks.

A Levi Strauss & Co. study, initiated in 2013, looked at three products: a pair of Levi’s® 501® jeans, a pair of Levi’s® Women’s jeans, and a pair of Dockers® Signature Khakis. This latest study benefited from the latest advancements in life cycle assessment scientific methods, tools and data collection processes and gives greater insight into the two biggest impact areas (cotton cultivation and consumer care) by expanding the scope of data collected.

This presentation dives deeply into the findings related to a pair of Levi’s® 501® medium stone wash jeans. The goal is that these findings will help LS&Co. and others in the apparel sector take more effective and holistic approaches to our industry’s environmental impact.

Fast fashion is a clothing supply chain model that is intended to respond quickly to the latest fashion trends by frequently updating the clothing products available in stores. The shift towards fast fashion leads to shorter practical service lives for garments. Collaborative consumption is an alternative way of doing business to the conventional model of ownership-based consumption, and one that can potentially reduce the environmental impacts of fashion by prolonging the practical service life of clothes. In this study, we used life cycle assessment to explore the environmental performance of clothing libraries, as one of the possible ways in which collaborative consumption can be implemented, and compared the advantages and disadvantages in relation to conventional business models. Furthermore, the key factors influencing the environmental impact of clothing libraries were investigated. We based our assessment on three key popular garments that are stocked in clothing libraries: jeans, T-shirts and dresses. The results showed the benefits of implementing clothing libraries associated with the garments’ prolonged service lives. Therefore to achieve environmental gains, it is important to substantially increase garment service life. Moreover, the results quantitatively demonstrated the potential risk of problem shifting: increased customer transportation can completely offset the benefits gained from reduced production. This highlighted the need to account for the logistics when implementing collaborative consumption business models.

The goal of this study was to build an up-to date and well-documented Life Cycle Inventory (LCI) for organic cotton fiber (ginned and baled), representative of worldwide global production. In addition, the study provides a full Life Cycle Impact Assessment (LCIA) of organic cotton fiber (comprising cultivation and ginning operations) and identifies environmental hotspots. To the effect of achieving these goals the relevant ISO standards 14040 and 14044 were followed. The process was verified by an accompanying independent critical review process.

The fashion supply chain is being challenged by a rising global population, increasing wealth and consumerism in the emerging markets, and the phenomenon of fast consumption in the developed world. Enormous strains are put on natural resources to keep up with consumer demand and solutions are needed for the massive waste flows downstream. Currently the main solutions for garments that cannot be reused are landfill, incineration for energy recovery, and downcycling. The latter is the recycling of garments into lower value products, such as insulation or wipers. Landfill and incineration cost money and these options do not deal with the natural resources issue since they do not displace the virgin fibre textiles industry. Downcycling does displace virgin fibre production, but applications have low profitability. High value recycling or “garment to garment recycling“is the concept of recycling used garments and textile waste into new garment products. This concept can reduce some of the pressure on virgin resources, while at the same adding value to waste to make recycling profitable for companies. This research assessed the environmental performance of two garment to garment recycling systems and one scenario as well as one downcycling system, in comparison with their equivalent ones made from virgin materials. The approach was based on life cycle assessment, and the impact categories chosen were climate change, acidification, eutrophication and water consumption. The study included primary data from different processes in the life cycle, including mechanical and chemical recycling, textile collection and manual and automated sorting.
