JOSEPHINE COPELAND and her 20-year-old daughter, Jo Jo, visited Primark at the Peacock Center mall here, in the London suburbs, to buy presents for friends, but ended up loaded with clothes for themselves: boots, a cardigan, a festive blouse, and a long silver coat with faux fur trim, which cost £12 but looks like a million bucks. “If it falls apart, you just toss it away!” said Jo Jo, proudly wearing her purchase. Environmentally, that is more and more of a problem.

With rainbow piles of sweaters and T-shirts that often cost less than a sandwich, stores like Primark are leaders in the quick-growing “fast fashion” industry, selling cheap garments that can be used and discarded without a second thought. Consumers, especially teenagers, love the concept, pioneered also by stores like H&M internationally and by Old Navy and Target in the United States, since it allows them to shift styles with speed on a low budget.

But clothes — and fast clothes in particular — are a large and worsening source of the carbon emissions that contribute to global warming, because of how they are both produced and cared for, concludes a new report from researchers at Cambridge University titled “Well Dressed?”

The global textile industry must become eco-conscious, the report concludes. It explores how to develop a more “sustainable clothing” industry — a seeming oxymoron in a world where fashions change every few months.

“Hmmm,” said Sally Neild, 44, dressed in casual chic, in jeans and boots, as she pondered such alien concepts, shopping bags in hand. “People now think a lot about green travel and green food. But I think we are a long way from there in terms of clothes. People are mad about those stores.”

It is hard to imagine how customers who rush after trends, or the stores that serve them, will respond to the report’s suggestions: that people lease clothes and return them at the end of a month or a season, so the garments can be lent again to someone else — like library books — and that they buy more expensive and durable clothing that can be worn for years.

In terms of care, the report highlights the benefits of synthetic fabrics that require less hot water to wash and less ironing. It suggests that consumers air-dry clothes and throw away their tumble dryers, which require huge amounts of energy.

But some big retailers are starting to explore their options. “Our research shows that customers are getting very concerned about environmental issues, and we don’t want to get caught between the eyes,” said Mike Barry, head of corporate social responsibility at Marks & Spencer, one of Britain’s largest retailers, which helped pay for the Cambridge study. “It’s a trend that we know won’t go away after a season, like a poncho.”

Customers “will ask ‘what are you doing?’ ” Mr. Barry said, noting that 70 percent of Britons shop at his chain. “So we’re doing a lot of thinking about what a sustainable clothing industry could look like in five years.”

Consumers spend more than $1 trillion a year on clothing and textiles, an estimated one-third of that in Western Europe, another third in North America, and about a quarter in Asia. In many places, cheap, readily disposable clothes have displaced hand-me-downs as the mainstay of dressing.

“My mother had the same wardrobe her entire life,” Ms. Neild said. “For my daughter, styles change every six months and you need to keep up.” As a result, women’s clothing sales in Britain rose by 21 percent between 2001 and 2005 alone to about £24 billion ($47.6 billion), spurred by lower prices, according to the Cambridge report.

And while many people have grown accustomed to recycling cans, bottles and newspapers, used clothes are generally thrown away. “In a wealthy society, clothing and textiles are bought as much for fashion as for function,” the report says, and that means that clothes are replaced “before the end of their natural life.”

Dr. Julian Allwood, who led a team of environmental researchers in conducting the report, noted in an interview that it is now easier for British consumers to toss unwanted clothes than to take them to a recycling center, and easier to throw clothes into the hamper for a quick machine wash and dry than to sponge off stains.

He hopes his report will educate shoppers about the costs to the environment, so that they change their behavior. There are many examples of how changing consumer priorities have forced even the most staid retailers to alter the way they do business.
