Understanding animal-derived

material supply chains

There are inherent risks and inescapable consequences associated with sourcing animal-derived materials. It is important that brands currently sourcing animal-derived materials have transparent supply chains in which all animal cruelty and exploitation risks are clearly understood. Without this information, brands are unable to make informed decisions about material sourcing, and potential material transition opportunities.

Below are a list of non-exhaustive but critical questions we encourages all brands to explore with their suppliers.


These questions were compiled on behalf of Copenhagen Fashion Week, as part of our fashion event engagement partnership with World Animal Protection. These questions are globally relevant, and brands seeking further advice on material sourcing and policies regarding ethics and sustainability can contact Collective Fashion Justice.

Brands currently sourcing animal-derived leather should consider the following questions:

Brands currently sourcing wool should consider the following questions:

For more information about wool production, consider reading Collective Fashion Justice’s report on wool sustainability, and our material guide for sheep and alpaca wool.

Brands currently sourcing cashmere should consider the following questions:

Brands currently sourcing feather down should consider the following questions:

Collective Fashion Justice is working towards a total ethics fashion system which prioritises people, our fellow animals and the planet before profit. This transition takes time and requires incremental yet bold steps forward.

This resource does not include supplier questions for any wild animals exploited for fur, skins or feathers, as the fashion industry has the capacity to immediately move beyond these.

While Collective Fashion Justice endorses the use of next-gen materials moving beyond leather, wool and other animal-derived materials, this transition will take time, requires planning, and a strategy to at least reduce suffering in the interim, while transition opportunities are developed.
