A system-wide transition is needed “immediately” to reduce environmental costs of the fashion industry, a new study from Finnish school Aalto University concludes in Nature Reviews Earth & Environment journal.
Fundamental changes to the fashion business model, including an urgent transition away from ‘fast fashion’, are needed to improve the long-term sustainability of the fashion supply chain, argue Kirsi Niinimäki and colleagues in their article published in Nature Reviews Earth & Environment.
The fashion industry is the second largest industrial polluter after aviation, and accounts for up to 10% of global pollution, it states.
Slow fashion is the future, but we need a new system-wide understanding of how to transition towards this model
However, the industry continues to grow, despite rising awareness of the environmental impacts, in part owing to the rise of fast fashion, which relies on cheap manufacturing, frequent consumption, and short-lived garment use.
The authors identify the environmental impacts of the fashion supply chain, from production to consumption, focusing on water use, chemical pollution, CO2 emissions and textile waste.
For example, the industry produces over 92 million tonnes of waste and consumes 79 trillion litres of water per year, with developing countries often bearing the burden for developed countries.
These impacts highlight the need for substantial changes in the industry, including deceleration of manufacturing and introduction of sustainable practices throughout the supply chain, the authors say.
“Slow fashion is the future”, Niinimäki and co-authors conclude, but “we need a new system-wide understanding of how to transition towards this model, requiring creativity and collaboration between designers and manufacturers, various stakeholders, and end consumers.”
A joined-up approach is required with the textile industry investing in cleaner technologies, the fashion industry developing new sustainable business models, and policy-makers modifying legislation, the study found.
Consumers also have a crucial role and must change their consumption habits and be ready to pay higher prices that account for the environmental impact of fashion, it says.
