What Makes Clothing Sustainable?

What Makes Clothing Sustainable?

The most sustainable fashion is that made using second hand materials, such as our sleeping bag jackets. If something is made new, how it will break down into the environment when discarded should be considered. Sustainability depends on waste, fabric, crops, dyes, climate change and ethics.


  • Different plants consume different amounts of water. For example, organic cotton uses 88% less water than traditional cotton. Therefore, clothes made from organic cotton are a better option. 
  • The use of pesticides or heavy metals on these plants can harmful to the land, farmers, and waterways.
  • Crops production can cause deforestation as land is cleared for crops. 
  • Crops can cause soil degradation and other damage to the land.  

The dyes used to colour clothing or print images ofen contain dangerous chemicals that are harmful to the environemnt, such as chlorine, heavy metals, and formaldehyde. These toxins  can get into the waterways and harm people or the land. Sustainable clothing only uses natural dyes that come from plants, vegetables and spices. 

Climate change

Consider the CO2 emissions and the use of fossil fuels throughout the whole line of production.

  •  Synthetic fibres such as polyester are made from fossil fuels, and are therefore bad. 
  • Source of energy during production.
  • Emissions during transportation - from the farm to the factory to the place of manufacturing to the store to the customer.
  • Methane emissions from animals from whom materials are derived. These materials include wool, leather and fur. 


  • When the customer eventually discards the item clothing most often ends up in landfill.
  • The quality and 'timlessness' of the item, as low quality items made to follow trends end up in landfill.
  • Toxins from dyes.
  • Pesticides from crops which eventually end up in waterways.
  • Fabric scraps from manufacturing.

. Packaging

  • Do the items come wrapped in plastic?
  • Are the postal packs biodegradable? (we use hero packaging - biodegradable).

This includes the social implications of workers and.

  • Minimum age of employment (aka no child labour).
  • Voluntarily chosen employment (aka no slave labour).
  • No gender discrimination (young women are often exploited to work). 
  • No discrimination in general.
  • The treatment of workers. This includes everyone from the manufactures to the farmers. For example, the use of chemicals in cotton farming has also been linked to premature death in cotton farmers. Some viable conditions include fair pay, fair working conditions (eg. days off and fair work hours), no forced overtime, and adequate health and safety conditions. 
  • No migrant exploitation (like hiring refugees)

    So what should I look out for?
    In general, a fabric that is synthetic (such as polyester or nylon) should be avoided  as it contains plastic. Natural fibres such as cotton break down easier, however these fibres often have their own implications with water consumption (cotton is one of the biggest water consumers). 
    In general, the best fabrics are - organic or recycled cotton, organic hemp, organic linen, organic bamboo, Tencel, Econyl, Ramie and recycled polyester (made from plastic bottles). However, beware of companies that claim their items are made using recycled materials - most often these companies only use these materials to make 2% of the item and try to mislead you with 'green' marketing. 
    Here are some to avoid - conventional cotton, synthetics (polyester, nylon, acrylic, viscose/rayon), wool, leather, down, most bamboo (this is a very grey area) and fur.
