Is Wool Ethical? What to Look For with Wool, Alpaca and Cashmere

As temperatures drop we want to stay comfy and cozy, many reaching for warm woolen sweaters and cardigans. Wool offers many great insulating and breathable properties and is wonderful in winter. However it comes from animals so for anyone concerned about animal welfare, questions about wool and animal cruelty come up.

Can Wool be an Ethical Material?

Unlike many other animals products, fibre animals do not need to be killed to obtain wool and many fibre animals need to shed to their fleece or be shorn yearly to stay healthy and comfortable. Wool falls into more of a grey area regarding ethical considerations and many people, including vegans, have different thoughts on if wool can actually be cruelty-free.

In my opinion it can be, depending on the circumstances. If sheep, alpacas, and goats are farmed, shorn, bred, and cared for in a healthy, respectful, and humane way then wool can be a responsible purchase.

Wool has been used and farmed for centuries and still plays an important role in many cultures. When fibre animals are not over-bred and farmed on mass-scale, it can also play a very important role within carbon farming and a regenerative agriculture system.

I’ve been interested in local clothing movements for a decade now and have visited and spoken with many farmers/ranchers. I’ve seen how fibre animals can be raised in a way where there is a respectful, symbiotic relationship between animals, humans, and the ecosystem. However it’s important to note that the average high street sweater unfortunately doesn’t represent these values and wool can also come from cruel and inhumane practices.

Factory Farming vs Regenerative and Indigenous Wool Farming

Like other things in the fashion industry, many of the ethical issues stem from a high demand for cheaper clothing which has created the harmful factory farming of fibre animals. Wool that comes from intensive farming focused on maximizing profits is harmful to animals and the environment, and the animals are seen solely as commodities instead of living beings.

Factory farming also seeks to maximize wool output by shearing animals multiple times a year, outside of their natural cycle (getting rid of their winter coats for spring and summer).

Whereas Indigenous and regenerative farming takes a holistic approach. It supports the long-term health of our environment, understanding the synergistic role animals play in agriculture and the respect and wellbeing they deserve.

Fibre farms can also be a big contributor towards soil erosion and desertification, however sustainable livestock and land management can actually reverse the issues and restore grassland ecosystems.

So is wool ethical? Yes and no it’s complicated. And like with most things in the fashion industry, we need to know where our clothing comes from and look for brands that are transparent about their wool and fibre sourcing and animal welfare standards.

Why not avoid all wool to be safe?

Sadly anywhere animals are involved there is the possibility of animal abuse and cruelty. If you want to try your best to ensure no animals were harmed then avoiding all animal products can be a good solution for some.

Unfortunately though the alternatives aren’t great and many have their own issues as well. Wool is a natural, highly functional, and durable clothing material that can’t be replicated with synthetic alternatives, and fibre farming has many benefits as part of a climate positive clothing production cycle.

I see a lot of value in wool as a material and in supporting brands who prioritize the wellbeing of animals and improving the environment, but this decision will be different for each person based on your values.

Types of Wool and Animal Fibres

🐑 Wool

Wool comes from sheep and has been used since the Stone Age to clothe and protect humans. As a fiber it contains many wonderful properties:

  • Wool is very durable and has natural elasticity – wool garments can last more than a lifetime.
  • It is antimicrobial and antibacterial. Meaning it does not need to be washed as often as other materials and doesn’t easily get smelly.
  • Wool has great thermoregulating properties. The unique structure can keep you both warm or also help with cooling. Wool can draw up to a third of it’s weight in moisture from the skin before feeling wet so you’ll be toasty warm without overheating or feeling sweaty or clammy.
  • Wool is also naturally stain and fire resistant.

There are a variety of types of wool from different breeds of sheep and some are more suited to certain types of clothing because of things like texture and itchiness. Depending on the garment, for example hiking clothing vs outerwear vs an everyday sweater, certain wool qualities (such as softness) will be more or less important.

Ethical Considerations: There devastatingly is no shortage of accounts of animal abuse in the wool industry. So when shopping for any wool product traceability and transparency is important.

Look for: Brands that have animal welfare and sustainable farming standards and policies. Ideally brands work directly with small family farms, have visited the farms, and know exactly where their materials come from.

You can also keep an eye out for Climate Beneficial™ wool meaning the wool was farmed within a regenerative agriculture system. It’s still a small certification, but hopefully will keep growing!

Merino Wool

I want to single out merino wool because this is a very common type of wool in apparel. It is a crimpy softer fiber and in high demand for it’s light weight and wicking properties as well as for comfort.

Ethical Considerations: Merino wool in particular has certain ethical issues to be aware of. Because it is in such high demand, merino wool can be over-bred and factory farmed, resulting in both environmental and animal cruelty issues. There is also a horrible practice called mulesing done to merino sheep which involves cutting away chunks of skin.

Look for: Brands that make it clear their wool is non-mulesed, have animal welfare standards, and sustainable farming practices.

ZQ certified wool – This is a certification that includes animal welfare, environmental, and social components and is also working to help farmer implement more regenerative practices.

What is alpaca wool? Ethics and sustainability of alpaca fiber

🦙 Alpaca

Alpaca is a wonderful material for sweaters and knitwear worn against the skin. It is fine, light, wonderfully soft and doesn’t contain lanolin – the oil most people who have wool allergies react to, so it’s naturally hypoallergenic and not irritating.

Ethical Considerations: Alpaca wool mainly comes from South America and the Peruvian highlands where animals live in their natural habitats and are farmed using indigenous and traditional methods. Alpacas can also live in rocky areas which are unsuitable for crops or other animals. Of all the animal fibres available, alpacas are most likely to be raised in a traditional and sustainable way. However there are also alpaca ranchers around the world with different practices.

It’s also important to note that “baby alpaca” does not mean it’s from the babies but rather refers to the finest grading of alpaca fibres.

Look for: Brands that are transparent and can trace their alpaca sourcing. Ideally brands that work directly with small, sustainable family farms.

🐐 Cashmere

Cashmere is the soft undercoat of the Kashmir goat. It is lighter and softer than wool and great for thinner, luxurious knits.

Ethical Considerations: Unlike sheep and alpaca, cashmere fibre is not shorn from the animals but combed out during their seasonal molting, many view this as a better option as it reduces the chance of cutting the animals (although a well-trained shearer should never cut the animals). However due to the high demand for cashmere some goat herds are intensively farmed and shorn instead of combed to cut costs (which also results in a poorer quality fibre).

Look for: Cashmere from the goats’ natural habitats in Asia and brands which sourced from farms with traditional and sustainable practices. Cashmere has also been a big contributor towards desertification so brands that care about responsible and restorative land management is also important.


Wool is a fascinating fibre and I feel like there is still so much to learn about it and regenerative fiber farming. If you are interested in learning more I recommend checking out Fibershed.

I’d love to know your thoughts on wool and the ethical dilemmas that come along with it.

    I have also heard that wool farms pretty much invariably “produce” lamb meat as well, and that in most case this is the most profitable option. There are way too many chances for abuse for me to realistically see me buying new wool products in the near future.

    Thank you, Verena, for your article on the ethical considerations surrounding wool production and purchase. It is disheartening to think that with the rise of fast fashion, fast fashion brands that produce woollen garments are supporting farming practices that treat livestock as commodities instead of living beings. Shearing animals outside of their natural wool production cycle. Thanks to your article, I’ll be researching the origins of woollen garments before I purchase any in the future. I think it is so important to understand where clothing is coming from these days and not taking everything for face value with greenwashing being a prominent problem in the fashion industry. Another point you brought up which interested me was regenerative fibre farming. It led me on a journey to find out more about the topic. I came across this article “Regenerative Wool: restoring Patagonia’s Grasslands with sheep” written in Lampoon magazine (online) which addresses wool production, climate and environmental impacts and may be of interest to you. It caught my eye as it states that Patagonia’s grasslands are some of the most damaged in the world yet they support multiple industries and livelihoods.
