Is cashmere bad for the environment?

Is cashmere bad for the environment?

The short answer: conventional cashmere production contributes significantly to grassland degradation in Central Asia, and this is a real environmental problem directly linked to demand for cheap cashmere. Cashmere comes from the fine undercoat of cashmere goats, raised primarily in Mongolia and Inner Mongolia (China). Demand for cashmere has grown substantially since the 1990s, driving rapid increases in herd sizes. In Mongolia, the number of cashmere goats increased from roughly 5 million in 1990 to over 27 million by 2020. Studies estimate that approximately 65–70% of Mongolia's grassland is now degraded to some degree — a significant portion attributed to overgrazing. Goats graze more destructively than sheep. They eat grass down to the root and use their hooves to excavate roots. In the fragile steppe ecosystem of Central Asia, this prevents grass from regrowing and causes permanent desertification. Land that was productive grassland a generation ago is increasingly bare ground.

How does this compare to other natural fibers?

Wool from sheep causes less land degradation than cashmere from goats, though overgrazing is a risk with sheep too in poorly managed operations. Linen (from flax) and cotton have no grazing impact at all — their sustainability concerns are about water use and pesticides, not land destruction. In terms of fiber yield: a merino sheep produces roughly 4–5 kg of raw wool per year. A cashmere goat produces approximately 150–200 grams of fine fiber. This makes cashmere far more resource-intensive per kilogram to produce, requiring significantly more animals and more grazing land for the same fiber output. For someone choosing between cashmere and merino wool on sustainability grounds, wool from a certified responsible source is the cleaner choice.

Does price reflect sustainability?

To a significant degree, yes. Responsible cashmere costs more to produce: certified land management, controlled stocking densities, and traceability throughout the supply chain all add cost. Brands that source responsibly pay more for the fiber. Very cheap cashmere — prices that seem too low for a luxury fiber — almost always indicates sourcing without these controls. The economics do not support responsible production at ultra-low price points. A cashmere sweater priced at $30–$50 is almost certainly not from a certified responsible source. This does not mean expensive cashmere is automatically sustainable, but it is a useful filter: anything priced below what responsible production costs is a signal to look more carefully.

What certifications exist for responsible cashmere?

Two main certifications cover cashmere land management and animal welfare: Sustainable Fibre Alliance (SFA) — works with herder communities in Mongolia to implement sustainable grazing practices. Requires stocking density limits, rotational grazing, and herd management planning. Verified through independent audits. Good Cashmere Standard (GCS) — developed by the Aid by Trade Foundation. Covers animal welfare and land use. Requires participating farms to meet standards on grazing management and animal treatment. Neither certification is perfect — auditing remote Mongolian steppe operations is genuinely difficult — but both represent meaningful commitments beyond unverified conventional sourcing.

Is there a sustainable alternative to cashmere?

For softness and warmth-to-weight ratio, the closest natural alternatives are fine merino wool and qiviut (muskox fiber). Qiviut is extremely soft and warmer than cashmere but very expensive and limited in supply. Fine merino from certified responsible sources (ZQ, RWS) is the most practical sustainable alternative. Alpaca fiber is another option — very soft, warmer than wool by weight, and produced from alpacas that graze more gently than cashmere goats. Alpaca is raised primarily in Peru, where overgrazing is less of a documented crisis than in Central Asia. For those committed to cashmere specifically: look for SFA or GCS certification, buy fewer pieces of higher quality, and care for them well. A cashmere sweater that lasts twenty years has a very different environmental footprint than one replaced every couple of seasons.
