Introduction: The Luxury Fiber’s Environmental Dilemma
Cashmere, often hailed as the “diamond fiber” for its unparalleled softness, warmth, and rarity, has long been a symbol of luxury in the fashion industry. Sourced from the undercoat of cashmere goats—primarily raised in temperate regions between 35 and 55 degrees north latitude, such as Inner Mongolia and Mongolia—it is a natural, biodegradable material by nature. Yet, the global demand for cashmere has surged in recent decades, driven by fast fashion and affordable luxury trends, leading to unsustainable practices that threaten ecosystems, wildlife, and local communities. From overgrazing-induced grassland desertification to energy-intensive processing and methane emissions, the cashmere industry faces significant environmental challenges. However, these issues are not inherent to cashmere itself; rather, they stem from irresponsible production and consumption. By adopting the right practices across the entire supply chain, cashmere can be transformed into a truly eco-friendly luxury—one that honors nature, supports communities, and preserves the fiber’s inherent value for generations to come.
Sustainable Sourcing: Protecting Grasslands and Goat Welfare
The foundation of cashmere sustainability lies in responsible sourcing, which begins with balancing goat herding with grassland health. Overgrazing by cashmere goats—whose voracious appetites and hooves damage vegetation—has long been a primary driver of desertification in key production regions. For example, Mongolia’s grassland ecosystems have suffered under the pressure of expanding goat herds, threatening species like snow leopards by reducing their natural habitat. To address this, regions like Inner Mongolia have implemented policies since 2011 to align herd size with pasture capacity, including grazing bans and rotational grazing systems. These measures have yielded tangible results: in Alxa League, the number of cashmere goats dropped from a peak of 1.48 million to around 450,000, while the average raw cashmere yield per goat increased from 300 grams to 500 grams. Additionally, selective breeding programs focus on producing finer cashmere (14.5 microns or finer), encouraging herders to prioritize quality over quantity—boosting their income while reducing environmental strain. Ethical herding also includes ensuring goat welfare, such as providing proper nutrition and veterinary care, aligning with global standards for animal-friendly production.
Eco-Friendly Processing: Reducing Energy, Water, and Emissions
After sourcing, the processing of raw cashmere—from cleaning and dehairing to spinning and dyeing—traditionally consumes large amounts of water and energy, while releasing harmful pollutants. However, innovative technologies and practices are transforming this stage into a more sustainable one. Leading brands like Erdos Group have adopted energy-saving dyeing technologies that break down pollutants into water and carbon dioxide, eliminating dyeing effluent and cutting water use for dark colors by half. Microbial dying technique, which uses natural pigments from fermented microorganisms instead of chemical dyes, further reduces environmental impact while preserving cashmere’s natural softness. Additionally, renewable energy sources are being integrated into processing facilities: Erdos’ ranches use solar panels to power operations, with surplus energy fed into the grid. These practices have led to significant carbon reductions—for instance, the carbon emissions from producing a 200-gram cashmere sweater fell by 11.43% in 2023 compared to 2022. Digital technologies like 3D modeling also minimize waste by reducing the need for physical sample production, cutting development time and material usage.
Circularity and Innovation: Extending Cashmere’s Lifespan
Sustainability in cashmere goes beyond production—it also involves extending the fiber’s lifespan and minimizing waste through circular practices. Regenerative cashmere, made from recycled and pre-consumer waste, is gaining traction: these materials are sanitized, sorted, and re-spun into new yarn, reducing the need for virgin fiber. Brands like Erdos have launched collections like “Shàn” that incorporate regenerated cashmere, along with other eco-friendly materials like yak wool. Additionally, practices like “coat-to-small-clothes” programs allow consumers to repurpose old cashmere garments into children’s clothing, giving the fiber a second life. Proper care and maintenance also play a role: professional cashmere care centers help extend the lifespan of garments, reducing the frequency of replacement. Furthermore, innovative treatments like water-wash processing and plant-based dyes eliminate harmful chemicals, making cashmere not only more sustainable but also safer for consumers and the environment.
Consumer and Brand Responsibility: Driving Systemic Change
Brands and consumers both play pivotal roles in making cashmere sustainable. Forward-thinking brands are investing in transparency and traceability: Zegna’s Oasi Cashmere, for example, is committed to making 100% of its fibers traceable by 2024, allowing consumers to track the journey from pasture to garment. Many brands also partner with local communities and research institutions to improve sustainable practices, such as Erdos’ collaboration with universities to develop green technologies and train herders. For consumers, choosing high-quality, sustainable cashmere—even at a higher price point—supports responsible practices and reduces the demand for cheap, unsustainable alternatives. Embracing a “buy less, buy better” mindset, caring for garments properly, and supporting brands with clear sustainability commitments can drive systemic change. Additionally, brands are raising awareness through initiatives like sustainable fashion stores (for example Erdos’ TENDER SPACE) that integrate eco-friendly design into their physical spaces, reinforcing the link between luxury and sustainability，
Conclusion: A Sustainable Future for Cashmere
Cashmere’s sustainability is not an unattainable goal—it is a choice, shaped by the practices adopted across every stage of the supply chain. From responsible herding that protects grasslands and animal welfare to eco-friendly processing that reduces emissions and waste, and circular practices that extend the fiber’s lifespan, the right actions can transform cashmere into a model of sustainable luxury. By balancing environmental stewardship, community support, and innovation, the cashmere industry can honor the fiber’s natural heritage while meeting the demands of conscious consumers. As brands and consumers increasingly prioritize sustainability, cashmere can continue to be a symbol of warmth and luxury—without compromising the planet. The future of cashmere is not just about producing a beautiful fiber, but about producing it in a way that nurtures nature, empowers communities, and ensures that this timeless luxury endures for years to come.
