    ①An increasing number of young people tend to rent clothes recently. Clothing rental is a hot new industry and retailers are entering this in hopes of attracting newly conscientious shoppers. This past summer alone, Urban Outfitters, Macy’s , Bloomingdale’s, American Eagle, and Banana Republic have all announced rental services—a sure sign of changing times.

②But is renting fashion actually more environmentally-friendly than buying it, and if so, how much more? Journalist and author Elizabeth Cline explored into this question and she concluded that its not as sustainable as it seems.

③Take shipping, for example, which has to go two ways if an item is rented—receiving and returning. Cline writes that consumer transportation has the second largest carbon footprint（碳足迹）of our collective fashion habit after manufacturing.

④She writes, “An item ordered online and then returned can emit（排放）20 kilograms of carbon each way, and up to 50 kilograms for rush shipping. By comparison, the carbon impact of a pair of jeans purchased in physical stores and washed and worn at home is 33.4 kilograms, according to a 2015 study by Levi's.”

⑤Then there’s the burden of washing, which has to happen for every item when returned, regardless of whether or not it was worn. For most rental services, this usually means dry-cleaning, a high-impact and polluting process. 70 percent of US dry cleaners used perchloroethylene, a carcinogenic（致癌的）air pollutant, which can produce harmful waste and air pollution .

⑥Le Tote is the only service that uses ‘wet cleaning’ for 80 percent of its items and strives to avoid dry cleaning unless absolutely necessary.

⑦Lastly, Cline fears that rental services will increase our appetite for fast fashion, simply because it’s so easily accessible. There’s something called ‘share-washing’ that makes people engage in more wasteful behaviors precisely because a product or service is shared and thus is perceived as more eco-friendly.

⑧Renting clothes is still preferable to buying them cheap and pitching them in the trash after a few wears, but we shouldn’t let the availability of these services make us complacent（自鸣得意的）. There’s an even better step --and that’s wearing what is already in the closet.
