In 2018, the Intergovernmental Panel on Climate Change sounded the alarm that if we don't rein in global warming to 1.5°C—we're already at 1°C above preindustrial levels—the impacts would be catastrophic. For its part, the clothing industry produces up to 10 percent of global carbon emissions. If business doesn't adapt, it'll claim three times as many resources by 2050. Considering how much stuff is already out there, reselling clothing should theoretically be a part of every brand's DNA. Plus, shoppers are already game. According to ThredUp, resale grew 25 times faster than traditional retail in 2019 and is poised to hit $64 billion by 2024. But for true circularity, brands have to implement the infrastructure so they're creating their own upcycling stream, rather than relying on other platforms to do the work for them.
