Fashion designer Stella McCartney condemned her industry as “incredibly wasteful and harmful to the environment” as she joined forces with the round-the-world sailor and environmental campaigner Dame Ellen MacArthur to call for a systemic change to the way clothing is produced and used.
In a report published on Tuesday, MacArthur’s foundation exposes the scale of the waste, and how the throwaway nature of fashion has created a business which creates greenhouse emissions of 1.2bn tonnes a year – larger than that of international flights and shipping combined.
It warns that “if the industry continues on its current path, by 2050, it could use more than 26% of the carbon budget associated with a 2C pathway.”
The report also reveals that less than 1% of material used to make clothing is recycled into new clothing; the estimated cost to the UK economy of landfilling clothing and household textiles each year is about £82m; a truckload of clothing is wasted every second across the world; the average number of times a garment is worn before it ceases to be used has decreased by 36% in 15 years; and that half a million tonnes of plastic microfibres are released per year from washed clothes contribute to ocean pollution.
MacArthur, who gained the support of industry leaders including the C&A Foundation, H&M, and Nike for her report, is calling for a circular textile economy to be created to make fashion more sustainable.
The report calls for four actions to be taken: to phase out substances of concern and microfibre release; increase clothing utilisation, for example by the industry supporting and promoting short-term clothing rental businesses; to radically improve recycling; to move to renewable materials.
McCartney said the ideas in the report provided solutions for an industry that was incredibly wasteful and harmful to the environment.
The report said more than half of “fast” fashion produced is disposed of in less than a year. In the US, clothes are only worn for around a quarter of the global average. The same pattern is emerging in China, where clothing utilisation has decreased by 70% over the last 15 years. Sixty percent of German and Chinese citizens admit to owning more clothes than they need.
Clothing production has nearly doubled in the last 15 years, and the growth is not just confined to the west. “Demand for clothing is continuing to grow quickly, driven particularly by emerging markets, such as Asia and Africa,” the report said.
“Should growth continue as expected, total clothing sales would reach 160m tonnes in 2050 – five times today’s amount.”
Greg Stanton, the mayor of Phoenix, Arizona, who is endorsing the report, said his city was attempting to create a circular economy out of textile waste: “Each year more than 18,000 tonnes of textiles find their way into … waste and recycling streams. Our city is working on creative solutions to redirect textiles from the waste stream … as a valuable resource, to ultimately stimulate the local economy.”
In east London, Cyndi Rhoades, founder of WornAgain, is working on the development of a new technology to separate and recapture polyester and cotton from textiles to be reintroduced back into the supply chain as new, raw materials.
She said: “We already have enough clothing and textiles in existence today to satisfy our annual demand of new raw materials for new clothing; all we have to do is make sure it doesn’t end up in the bin, and processes like ours are scaled as rapidly as possible.”
