Good question! And it’s well-timed, because it feels as though fast fashion is trying every greenwashing trick in the book to convince us that they are “going green”.
Let’s unpack that.
First let’s remind ourselves about what fast fashion is. Fast fashion is a fashion business model that aspires to ever-increasing profits and economic growth. Overproduction and overconsumption are the drivers of this growth.
Enabling overproduction and overconsumption means creating clothing (typically made from synthetic plastic fibers) that is cheaply made, mass-produced, and rapidly produced. This clothing copies styles worn on runways, by celebrities, on social media, and created by independent designers.
Some fast fashion retailers might even copy from other fast fashion brands’ designs (or knock-offs).
Fast fashion brands, such as Zara and H&M, release new styles on the weekly. Now we’re also seeing the rise of ultra-fast fashion giants — including Shein, Boohoo, and Pretty Little Thing — that introduce thousands of new styles daily.
Fast fashion is artificially cheap. Prices are kept low so that people don’t think twice about buying more. These low prices enable corporations to produce more, because it costs so little. This low cost hides the true environmental cost of this overproduction which includes carbon emissions, plastic pollution, excessive water use, and loss of biodiversity.
This cheap clothing affects people too. The people in fast fashion supply chains are stuck in cycles of poverty, because they are not paid living wages. The health of communities in garment production regions suffer because of the use of toxic chemicals and pollution. And communities in the Global South, as well as natural environments, shoulder the burden of the waste that comes from creating too much clothing.
So this business model is fundamentally dependent on unjust exploitation and extraction. Exploitation and extraction will never be sustainable.
Because of this, the simple answer to your question is: no, fast fashion as a business model will never be sustainable.
But here’s where the confusion comes in. As we live through a climate crisis and the sustainable fashion movement continues to grow, fast fashion has caught onto these rising sustainability concerns.
In attempts to remain relevant and retain — or even grow — their customer base, they are trying everything from conscious collections made with natural and recycled fibers, in-store take-back programs that promise to recycle your old clothes, to sustainability reports, and sustainable fashion certifications.
To be clear, this still doesn’t make fast fashion sustainable. It’s a flawed business model, because the speed and volumes that these corporations produce completely overshadow any material innovations they are trying to convince us of.
We call these efforts greenwashing, because these companies are choosing sustainability efforts that align with their growth objectives. Instead of pointing out what they are doing, we need to ask ourselves what they are not telling us.
A topic you’ll never hear fast fashion addressing is improving the livelihoods of their workers and paying living wages. Sustainability isn’t only about eco-friendly materials, it’s also about ethics and caring for the people in your supply chain.
Another thing you’ll never hear fast fashion corporations talking about and advocating for is slowing down and degrowth. Unless they start producing less, their harm will always remain — no matter how much marketing fuss fast fashion brands make about their material innovations and attempts to go circular.
The mounds of clothing flooding Global South communities, like the Kantamanto market in Ghana, will continue to grow — even if they are now made of vegan leather or recycled polyester.
The reason that fast fashion brands are pushing their eco-friendly initiatives, without slowing down or improving the lives of workers, is that they see it as another opportunity for growth. And yet another opportunity for us to buy more. Fast fashion wants to “go green” without compromising on their profit margins and taking accountability for its social and environmental injustices.
So let’s be clear: the fast fashion business model is the fashion industry’s sustainability problem. Unless the business model changes, nothing else ever will.
But as a reminder, this doesn’t mean we should shame people who buy fast fashion when it’s what is most accessible to them. And wearing and loving the fast fashion garments you already own will always be sustainable. But more on that another time!
