    Clothing rental is a hot new industry and retailers (零售商) are demanding to get on board in hopes of attracting green shopper.

But is renting fashion actually more environmentally-friendly than buying it, and if so, how much more? Journalist and author Elizabeth Cline investigated (调查) this question and concluded that it's not as sustainable as it seems.

Take 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 of our collective fashion habit after manufacturing.

She writes, ''An item ordered online and then returned can send out 20 kilograms of carbon each way, and increases up to 50 kilograms for rush shipping. By comparison, the carbon impact of a pair of jeans purchased from a physical store and washed and worn at home is 33.4 kilograms, according to a 2015 study by Levi's.''

Then there's the burden of washing, which has to happen for every item when it's returned, regardless of whether or not it was worn. For most rental services, this usually means dry cleaning, a high impact and polluting process. All the rental services that Cline looked into have replaced perchloroethylene (氯乙烯), a carcinogenic (致癌的) air pollutant, still used by 70 percent of US dry cleaners, with alternatives, although these aren't great either.

Lastly, 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 waste more precisely because a product or service is shared and thus is regarded as more eco-friendly. Uber is one example of this, advertised as ''a way to share rides and limit ear ownership.'' and yet ''it has been proven to discourage walking,bicycling, and public transportation use.''

Renting clothes is still preferable to buying them cheap and throwing them in the dustbin after a few wears, but we shouldn't let the availability of these services make us too satisfied. There's an even better step — that's wearing what is already in the closet.
