<h2>What Is Wool?</h2><p>Wool is a textile fiber obtained from the fleece of animals such as sheep, alpacas, and goats. It is known for its insulation, moisture-wicking, and flame-resistant properties. Common types include merino wool (from Merino sheep), cashmere (from cashmere goats), and alpaca wool. Wool is biodegradable under the right conditions but processing often involves chemicals like chlorine for shrink-proofing.</p><h2>Where Does Wool Come From?</h2><p>Major wool-producing countries include Australia (around 25% of global supply), New Zealand, China, and South Africa. Sheep farming ranges from small-scale pasture systems to large industrial operations. Alpaca wool is primarily from Peru and Bolivia, while cashmere comes from China, Mongolia, and Iran. The supply chain includes shearing, washing, carding, spinning, and weaving.</p><h2>Animal and Environmental Impact</h2><p><strong>Mulesing:</strong> In Australia, some Merino lambs undergo mulesing—cutting skin from the breech area without pain relief to prevent flystrike. This practice is banned in New Zealand and many European countries. Brands using non-mulesed wool may label it as such. <strong>Transport:</strong> Live sheep exports from Australia to the Middle East have raised welfare concerns due to overcrowding and heat stress. <strong>Land use:</strong> Sheep grazing can lead to overgrazing, soil erosion, and water depletion, especially in arid regions. Wool production also emits methane (a greenhouse gas) from sheep digestion. However, well-managed rotational grazing can improve soil carbon sequestration.</p><h2>How to Spot Ethical Wool on Labels</h2><ul><li><strong>ZQ Merino Standard</strong> – Requires non-mulesing, ethical animal treatment, and environmental criteria.</li><li><strong>Responsible Wool Standard (RWS)</strong> – Certifies animal welfare and land management; third-party audited.</li><li><strong>GOTS (Global Organic Textile Standard)</strong> – For organic wool, includes processing and social criteria.</li><li><strong>Non-mulesed</strong> – Explicitly stated on some Australian wool products.</li><li><strong>Oeko-Tex Standard 100</strong> – Tests for chemical residues, but not animal welfare.</li><li>Avoid generic ‘wool’ without certification if animal welfare is a priority.</li></ul><h2>Alternatives to Wool</h2><p>Consider these materials for warmth and durability with lower ethical and environmental impact:</p><ul><li>Tencel Lyocell (from sustainably sourced wood pulp)</li><li>Hemp (requires less water and land)</li><li>Organic cotton (no synthetic pesticides)</li><li>Recycled polyester (from plastic bottles)</li><li>Lenzing Modal (from beech wood, closed-loop process)</li></ul><!--freshness:faq--><div class="faq"><h2 id="faq">Frequently asked questions</h2><h3>Is wool biodegradable?</h3><p>Yes, untreated wool biodegrades in soil within months to years, but wool treated with chlorine or other chemicals may degrade more slowly.</p><h3>What is mulesing and why is it controversial?</h3><p>Mulesing is the cutting of skin from a lamb's rear to prevent flystrike, typically done without pain relief.

Wool
Wool is a natural fiber sheared from sheep, alpacas, or goats, valued for its warmth and biodegradability. Ethical concerns include mulesing (a painful practice in Australian sheep farming), animal welfare during transport, and environmental impacts from grazing and land use. Look for certifications like ZQ or Responsible Wool Standard to support better practices.
Ethical alternatives
Lower-impact substitutes that formulators reach for when replacing wool.
Impact notes
Sheep farming for wool contributes to methane emissions and land degradation, especially in dry regions. Mulesing remains a widespread welfare issue in Australia, affecting millions of lambs annually. Transport of live sheep for slaughter adds further suffering, though some regions have banned the practice.

It cuts plastic waste but still sheds microplastics during washing, posing environmental concerns. No major certification currently verifies rPET content alone, so consumers must rely on brand transparency.
