LEVI’S 501 DAY | CUTTING FROM A GREENER DENIM CLOTH
If you had to pick just one article of clothing to represent pure American style– what would it be? For me it would without a doubt be the Levi’s 501 jean without a doubt. It embodies so much of this great country’s heritage– from tough prospecting roots, to a symbol of 1950′s teenage rebellion and everything in between– it’s a staple of everyday life, and at the same time a firmly established fashion icon that still inspires designers here and abroad.
Buying a new pair of 501′s has long been a ritual of love for me. Going through the stack, looking for little signs that will lead me to the perfect pair– side belt loops stitched directly to the back-yoke seam, side seam spread wide to provide great wear ‘tracks’ down the road, maybe even a little hint of leg twist already apparent…
To celebrate this year’s 501 Day (on May 1st of every year) Levi’s is launching an organic update of the classic 1947 501 jean. It’s a reflection of their ongoing commitment to move towards more humane and environmental practices for their workers and the planet.
From the San francisco Business Times–
For the world’s oldest and most iconic jeans maker, going green is about more than doing what’s right.
“In one way, it’s a matter of survival as a company,” said Michael Kobori, vice president of supply chain, social and environmental sustainability at Levi.
Levi Strauss & Co., born in 1853 at the height of the Gold Rush, has always prided itself in its corporate citizenship. It has been a leader in AIDS support and prevention and has formed initiatives to address institutional racism and programs to assist employees in becoming U.S. citizens. Founder Levi Strauss was a well-known philanthropist.
But its new vision, the one that will determine if Levi can survive and thrive for another 150 years and beyond, is as much about the bottom line as it is about helping the Earth.
Levi adopted a new mission statement in March 2008: “We will build sustainability into everything we do so our profitable growth helps restore the environment.”
The company has just received the results of a lifecycle analysis for its Levi 501 jeans and Dockers brand Original Khaki. The study looked at the impact their production has on the environment from the cotton field to a consumer’s closet, all the way to what happens to jeans once they’ve enjoyed their last wear. The point is to figure out how to reduce its impact on the environment, head off risk associated with increasingly strict environmental regulations, cut rising energy costs and bolster profits.
Jeans production is resource intensive: Levi’s lifecycle analysis showed that one pair of jeans produces 33.2 kilograms of carbon dioxide, and uses 3,480.5 liters of water and 400.1 megajoules of energy. That’s the equivalent of driving a car 78 miles, taking 53 showers and watching a plasma TV screen for 318 hours.
“If we can consume less energy, materials, and water, we can reduce our costs, and those cost savings drop to the bottom line,” Kobori said.
Denim’s carbon footprint
The inherent challenges to document, let alone reduce, its impact on the environment are obvious for Levi.
The company is dependent on the notoriously pesticide- and water-intensive cotton industry. Levi also has a massive, worldwide supply chain. That complicates its ability to trace its environmental footprint as materials move from growers to the processors and millers, to the dyers and sewers and finally to retail stores.
Armed with the results of the life cycle analysis, the company will look for ways to reduce energy use along its supply chain. It’s encouraging suppliers to recycle process water and experiementing with finishing techniques that would use less water in making jeans. It’s also commissioned a study of its facilities’ greenhouse gas emisisons and will set targets to reduce those next year after results are finalized.
Cold water, tumble dry warm
Some of the changes are simple.
In initial studies, Levi discovered that the two phases that account for the most energy use and greenhouse gas emissions along the life cycle of a pair of jeans are the fabric-production phase — 21 percent of the total climate change impact — and the consumer use phase, which accounts for 58 percent of a pair of jeans’ climate impact.
People tend to keep the same pair of jeans for years and they might wash them hundreds of times. For decades Levi has instructed people to wash jeans in warm or hot water and tumble dry.
“We can’t change consumer behavior but we can certainly change what we’re directing them to do, so we’re changing all of our care labels worldwide to say wash in cold water, tumble dry warm,” Kobori said.
If customers follow those instructions, they could reduce energy used over the life of their jeans by 87 percent and reduce carbon emissions by 90 percent. And the company is considering how to use fabrics that don’t need to be washed as often and, at the retail level, about encouraging customers to wash jeans less to conserve water and energy.
The company is also working on sharing water quality standards from its factories with other companies and has started a sustainable cotton group to look at the environmental issues around cotton and what changes Levi could make.
Levi is phasing in organic cotton into one line of its products and has joined the Organic Exchange, which supports organic farming and works with companies to use more organic products. So far 1 percent of the cotton Levi uses is organic and goes into its “eco” line of products, which also contains 20 percent post-consumer denim. Organic cotton makes up less than one percent of all the cotton grown in the world, so even if Levi wanted to switch to 100 percent organic cotton for all of its products, it most likely couldn’t find the supply.
“Their effort is similar to what other companies are doing,” said Rebecca Calahan Klein, director of program development for the Berkeley-based Organic Exchange, which supports organic farming. “They have not transitioned all of their product. They’re being structured and systematic about how they’re integrating organic cotton into their product offering. And that’s good. We want people to be thoughtful about how they do it because we want it to be sustainable.”
Levi is smart to be looking at these issues before it is forced to, said Gil Friend, president and CEO of Berkeley-based strategic consulting firm Natural Logic.
“From a company point of view you can see this as a market share growing strategy or a risk-mitigation strategy,” he said. “What you really can’t do any more is an ‘I’m going to sit on my hands until I have to do something strategy.’ It’s not good business management any more.”
FROM COTTON FIELDS TO RECYCLE BIN
Levi Strauss & Co. recently commissioned a study to find out the climate impact in making Levi’s 501 jeans. The company will use the results to reduce the impact of its products over their entire life cycle.

78 miles driven by the average auto in the
