The carbon footprint of fast fashion consumption and mitigation strategies-a case study of jeans

Fast fashion is driving the continued growth of the fashion industry's carbon emissions. Understanding how fast fashion consumption exacerbates carbon emissions is critical to guide mitigation strategies for the fashion industry. Taking jeans, a typical fast fashion product as an example, this study developed an LCA model to assess the carbon footprint of fast fashion consumption at global and national levels, and mitigation potentials of product service systems-related scenarios were then explored. Results show that the carbon footprint of fast fashion consumption is 2.50 kgCO2e/one wear jeans, 11 times higher than that of traditional fashion consumption. Jeans production and cross-broad transportation contributed 91 % of the carbon footprint of fast fashion consumption. Developed countries have a 53 % higher per capita carbon footprint of fast fashion consumption than developing countries. The second-hand trading model has the highest mitigation potential, reducing carbon emissions by 90 %. This study proposed an analytical framework for the carbon footprint of fast fashion consumption, which provides the basis for the environmental footprints of fast fashion products. Our findings provide insights into the carbon footprints of traditional and fast fashion consumption and strategies for the transition to circular fashion.

From the closet to the shore: Fashion waste pollution on Colombian Central Caribbean beaches

This paper examines the environmental effects of fashion waste on the central Caribbean coast of Colombia, highlighting significant ecological issues in coastal areas. A survey of 27 beaches found 503 items of fashion waste, mainly shoes and sandals, with an average density of 0.93 items/m2. The distribution of this type of waste varies notably across different beach types, with exposed, rural, and remote beaches showing higher accumulation, indicating a relationship between beach characteristics and waste concentration. Primary sources of this waste include riverine transport, coastal tourism, and poorly managed sewage systems, impacting urban, rural, and village beaches differently. The study reveals that longshore currents and oceanic movements, significantly influence the transport and fate of this waste, with exposed beaches accumulating more fashion waste than sheltered ones. The presence of driftwood also plays a vital role in trapping fashion waste along coastlines. The findings highlight the need for effective management strategies to mitigate the impact of fashion waste, providing crucial insights for local and national coastal managers and implications for managing fashion waste in the Southern Caribbean and similar regions worldwide.

On the horns of a dilemma: Evaluation of synthetic and natural textile microfibre effects on the physiology of the pacific oyster Crassostrea gigas

Fast fashion and our daily use of fibrous materials cause a massive release of microfibres (MF) into the oceans. Although MF pollution is commonly linked to plastics, the vast majority of collected MF are made from natural materials (e.g. cellulose). We investigated the effects of 96-h exposure to natural (wool, cotton, organic cotton) and synthetic (acrylic, nylon, polyester) textile MF and their associated chemical additives on the capacity of Pacific oysters Crassostrea gigas to ingest MF and the effects of MF and their leachates on key molecular and cellular endpoints. Digestive and glycolytic enzyme activities and immune and detoxification responses were determined at cellular (haemocyte viability, ROS production, ABC pump activity) and molecular (Ikb1, Ikb2, caspase 1 and EcSOD expression) levels, considering environmentally relevant (10 MF L^-1) and worst-case scenarios (10 000 MF L^-1). Ingestion of natural MF perturbed oyster digestive and immune functions, but synthetic MF had few effects, supposedly related with fibers weaving rather than the material itself. No concentration effects were found, suggesting that an environmental dose of MF is sufficient to trigger these responses. Leachate exposure had minimal effects on oyster physiology. These results suggest that the manufacture of the fibres and their characteristics could be the major factors of MF toxicity and stress the need to consider both natural and synthetic particles and their leachates to thoroughly evaluate the impact of anthropogenic debris. Environmental Implication. Microfibres (MF) are omnipresent in the world oceans with around 2 million tons released every year, resulting in their ingestion by a wide array of marine organisms. In the ocean, a domination of natural MF- representing more than 80% of collected fibres-over synthetic ones was observed. Despite MF pervasiveness, research on their impact on marine organisms, is still in its infancy. The current study aims to investigate the effects of environmental concentrations of both synthetic and natural textile MF and their associated leachates on a model filter feeder.

Post-Consumer textile waste and disposal: Differences by socioeconomic, demographic, and retail factors

The amount of post-consumer textile waste (PCTW) generated annually in the United States has increased nearly ten-fold since the 1960s to exceed more than 34 billion pounds annually. Of the waste generated, 66% is sent to landfills, 19% is combusted with energy recovery, and only 15% is recycled. When left to decompose in landfills, PCTW decomposes, producing harmful leachates and greenhouse gases including methane. In this study, we used publicly available data from 67 counties in the state of Florida from 2014 to 2019 to assess how PCTW generation and recycling behaviors differ by area-level demographic, socioeconomic, and retail characteristics. We also used publicly available data on landfills to determine whether these same factors were associated with having more landfills per capita in a county. This study provides preliminary evidence that people living in areas with higher incomes, that are more racially segregated, and that have more clothing stores generate significantly more textile waste than people in other areas. In contrast, there were more landfills per capita in areas with lower incomes and fewer landfills per capita in areas that were more racially segregated.Textile recycling occurred at relatively uniform rates across counties. Taken together, these findings support the understanding that textile waste represents an issue of environmental injustice; wealthier communities contribute more PCTW to landfills, which are more commonly located in communities with lower socioeconomic status. Multipronged solutions are needed to produce relevant behavior change, including efforts and policies that seek to reduce textile consumption and increase textile recycling at the individual and societal level.

Comparative analysis of sustainability measures in the apparel industry: An empirical consumer and market study in Germany

The pressure on the apparel industry to make its products more sustainable is growing. Concrete measures have hardly been taken so far, also because they aim to avoid consumption which reduces profits. Studies mostly examine impacts on the environment, but not how the market volume can remain at a maximum for producers. To uncover direct market effects from sustainability approaches, this study asked 500 German consumers about their willingness-to-pay and preference order for three different measures, namely "slowing in consumption", "recyclability of petrochemical clothing" or its "production from bioplastics". An outdoor trekking jacket served as test object, and influences from sociodemographic and latent variables, as sportiness and environmental awareness, were measured. The results were mapped in a market model from which the output volume was derived. It was found that interest in the topic of plastics-containing outdoor clothing was rather determined by the application. This increased with the sportiness of the respondents (r = 0.13; p = 0.003), but not with their personal environmental awareness. Consent to bioplastics use did not depend on the level of experience, but older consumers appreciated this option more (p = 0.027). Only 20% of the respondents favoured slowing, 26% bioplastics, but 53% recycling of petroplastics. Therefore, research should investigate recyclability, policy should support this measure, and companies should practice take-back and reuse in new clothing. Consumers can maintain fast consumption and would even accept higher prices.

The global environmental injustice of fast fashion

Fast fashion, inexpensive and widely available of-the-moment garments, has changed the way people buy and dispose of clothing. By selling large quantities of clothing at cheap prices, fast fashion has emerged as a dominant business model, causing garment consumption to skyrocket. While this transition is sometimes heralded as the "democratization" of fashion in which the latest styles are available to all classes of consumers, the human and environmental health risks associated with inexpensive clothing are hidden throughout the lifecycle of each garment. From the growth of water-intensive cotton, to the release of untreated dyes into local water sources, to worker's low wages and poor working conditions; the environmental and social costs involved in textile manufacturing are widespread.In this paper, we posit that negative externalities at each step of the fast fashion supply chain have created a global environmental justice dilemma. While fast fashion offers consumers an opportunity to buy more clothes for less, those who work in or live near textile manufacturing facilities bear a disproportionate burden of environmental health hazards. Furthermore, increased consumption patterns have also created millions of tons of textile waste in landfills and unregulated settings. This is particularly applicable to low and middle-income countries (LMICs) as much of this waste ends up in second-hand clothing markets. These LMICs often lack the supports and resources necessary to develop and enforce environmental and occupational safeguards to protect human health. We discuss the role of industry, policymakers, consumers, and scientists in promoting sustainable production and ethical consumption in an equitable manner.
