Major fashion brands continue to rely on synthetic fibers despite increasing regulatory pressure, according to a report released by the Changing Markets Foundation. The study examined 50 companies across fast fashion, sports, and luxury sectors, revealing that Inditex, owner of Zara, uses the highest volume of synthetic fibers, with its use of fossil-based materials growing by nearly 20% since the last survey. Shein, a fast fashion giant, had the highest ratio of synthetic to natural fibers, with 82% of its materials coming from fossil sources. Eleven of the 23 companies that provided additional data to Changing Markets reported an increase in fossil fuel-based fabrics, mainly polyester, while three companies noted reductions.
The study was conducted by Changing Markets along with several other organizations, including the Clean Clothes Campaign and Fashion Revolution. It relied on data from surveys and publicly available information, but 54% of the contacted companies failed to respond, marking an increase in non-participation from previous years. Only six companies, including Inditex, Lululemon, Mango, and Nike, publicly disclose the volume and share of synthetic fibers they use.
The report indicates that synthetic fibers account for 69% of global textile production, a figure expected to rise to 73% by 2030. The authors argue that the affordability and versatility of materials like polyester have enabled brands to flood the market with cheap clothing, fueling the cycle of fast fashion. Companies like Reformation and Hugo Boss are recognized for efforts to reduce reliance on synthetics, but progress remains inconsistent. Changing Markets emphasized that stronger regulatory measures are needed to reduce the industry's dependence on fossil fuels and address its environmental impact.
