What we choose to wear can change the world
Ali Kelly

Our fashion system relies on overconsumption. Since the 1980s we have seen the rise of ‘Fast fashion’, a new business model which involves more fashion collections every year, quick turnarounds, lower prices and often lower quality items. It is trend driven and brands react quickly to capitalise on the latest looks.1 This system creates excessive waste at every stage of the process and is having a detrimental effect on our climate and biodiversity. Here are some of the facts: 

  • Climate Change: Our fast fashion habit is fuelling climate change. Across the full lifecycle of clothing globally, the industry has an annual carbon footprint of 3.3 billion tonnes CO2e. This is almost equivalent to the total carbon production of the EU 28 member states!2
  • Land Use: The most carbon intensive part of the process is the production of fibres such as cotton – and this is growing.  The industry is projected to use 35% more land for fibre production by 2030— an extra 115 million hectares that could be left for biodiversity or used to grow crops to feed our expanding population.3
  • Synthetic Fibres: An increasing number of garments are being made with synthetic fibres. These are often even more carbon intensive. A single polyester shirt has more than double the carbon footprint of a cotton shirt (5.5 kg  CO2e vs. 2.1 kg CO2e).4 The use of plastics in clothes is having a detrimental impact on animal and marine life. 20% to 35% of all primary source microplastics in the marine environment are from synthetic clothing.5 A single 6kg domestic wash has the potential to release as many as 700,000 fibres.6
  • The way we look after our clothes is changing too. We tend to wear our clothes for shorter periods of time, and buy new instead of making simple repairs. Around 300,000 tonnes of household waste each year is made up of garment waste.7 The ability to recycle textiles is limited and most recycling processes currently use damage the existing fibres. Most synthetic fibres are made from virgin, rather than recycled plastics due to the cost. 

And this is all before we consider the human rights abuses and social costs of the industry. However – it is not too late, if we can ACT NOW we can decrease the carbon cost of our clothes and the industry, but still enjoy the fun and creativity of fashion!
