Not needing to wash your clothes as much helps, too. To minimize this footprint, wash using cooler water and line-dry your items, experts recommend. While the biggest share of the emissions tied to apparel comes from textile production - 41% - the second largest source is from consumption, which largely comes down to the energy associated with washing and drying. The way you wash your clothes also matters from a climate perspective. That means someone would have to wear them more than 30 times to get the most out of them. Led by the Ellen MacArthur Foundation, a coalition of academic experts, brands, retailers, manufacturers and others developed jeans guidelines, deciding that jeans should be able to withstand a minimum of 30 washes at home while still retaining their high quality. Perhaps the closest thing to this number is a new durability metric for jeans. On its current path, the Ellen MacArthur Foundation estimated, the industry could use up more than 26% of the carbon budget remaining if we are to limit global warming to 2 degrees Celsius by 2050. Big fashion accounts for 2% to 8% of global carbon emissions, according to the UNEP. It’s no secret that the fashion industry has a pollution problem. The numbers are undeniable: “It wouldn’t be physically possible to get as much wear out of your items as it previously had because people have got a lot sitting in their wardrobes.” “The way that the sales were growing, people were starting to own more and more clothes,” said Laura Balmond, Ellen MacArthur Foundation’s Fashion Initiative lead. But skyrocketing clothing sales suggest many people worldwide are buying more than they used to just a couple decades ago - and also buying more than they can really use. If you’re someone who wears clothes until they fall apart, ripped and ragged, this hot climate tip is not for you. Here’s why: Wearing the stuff you already own likely means that you will buy less in the future, thus preventing the greenhouse gas emissions generated during the production of new items.
People doing so could reduce the related emissions impact of clothing by 44%, according to a 2017 report from the charity Ellen MacArthur Foundation, later echoed by the United Nations Environment Programme (UNEP). A small, simple and cheap way to prevent some future climate pollution is to wear the clothes already in your closet roughly twice as many times as you might have otherwise before tossing them.
