One would be surprised to associate jeans with global warming. However, the garment industry is a resource-intensive sector that accounts for 10% of global carbon emissions, making it the second largest polluting industry behind the oil industry. [1][2] Given its resource reliance, climate change\u2019s effects on resource availability is poised to introduce severe shocks into the garment industry\u2019s supply chain, affecting its ability to meet customer demand. A few companies, however, are taking proactive stances to reduce their raw material footprint, thereby re-introducing stability into their supply chains. One such company is Levi Strauss, which made a high-profile commitment in 2008 to reduce their climate footprint by five percent annually up to 2020.<\/p>\n
Climate change will adversely affect the garment industry\u2019s access to its required raw materials, including cotton and water. First, climate change affects the yields on cotton crops, pushing up the price of cotton. One study projects yields on US crops, such as cotton, will decrease by 30-82% at the end of the century, depending on the degree of temperature increase. [3] Another study projects a price increase of 135% assuming a 5\u00b0C temperature increase. [4] If the trend continues, cotton will be too expensive or scarce for the industry to maintain its current ~7% margin profile. [5]<\/p>\n
Second, cotton products need significant amounts of water. More than 100 gallons of water is required to cultivate a single pound of raw cotton. [6] In 2009, Levi\u2019s estimated that a pair of blue jeans consumes 919 gallons of water during its life cycle, from production to wash cycles. [7] On the other hand, access to water will shrink significantly. By 2030, demand may outstrip water supply by 40%. According to some projections, by 2090, 30% of the earth\u2019s surface could be in severe drought, up from 1-2% today. [8] As water supply shrinks, not only will crop yields continue to decline, but garment manufacturers, such as Levi\u2019s, will lack access to the water required to cultivate cotton and manufacture jeans.<\/p>\n
While the garment industry is only now taking action in response to climate change, Levi\u2019s has been leading the charge. Since 2007, they have introduced sustainability goals at each step of their supply chain, with an overarching goal of sourcing sustainable cotton and reduce water consumption across the supply chain.<\/p>\n
The \u201cBetter Cotton Initiative\u201d (BCI) is one of their higher-profile efforts to change how cotton is grown, from improving labor standards to decreasing the environmental impact of cotton farming. BCI works directly with farmers to improve yields while reducing water usage. Techniques cover a wide range of agricultural practices, including efficient irrigation. BCI then certifies farms that meet its strict standards. Farms that adhere to BCI standards use 23% less water than their non-BCI counterparts. [9] In a particularly successful deployment, BCI helped over 75,000 cotton farmers in Pakistan reduce their water consumption by 39%. [10]<\/p>\n
Levi Strauss sourced 12 percent of their total cotton in 2015 from BCI-certified farms, up 5% from 2014. [11] Their goal is to source 100% sustainable cotton by 2020. Given the projected decrease in cotton yields and water availability, Levi Strauss\u2019 investment in programs like the BCI will help them insulate their supply chain while reducing their impact on the environment.<\/p>\n
Levi Strauss\u2019 other high-profile effort is the \u201cWater + Production\u201d program, which aims to reduce water usage in the manufacturing process. Levi Strauss pioneered methods to reduce water usage in certain stages of the production cycle, aiming to cut down on the 919 gallons of water required during the lifecycle of a pair of jeans. Since rolling out these methods in 2011, they have saved over one billion gallons of water and reintroduced 30 million gallons of water back into the ecosystem. They project they can save up to 96% of water in the finishing process for certain style of jeans. Levi\u2019s hopes to increase the percentage of products using these water saving techniques, to 80% in 2020 from 25% today. [12]<\/p>\n
Levi Strauss\u2019 sustainability programs are a classic example of incentives aligning, as climate change will not only increase their raw material and production costs, but these programs introduce an opportunity for them to improve their production costs today and align with changing customer preferences in terms of sustainable manufacturing practices. However, they can, and should, set loftier goals. They can achieve those via a tighter supply chain integration \u2013 for example, via vertical integration or strict standard enforcement. Their collaboration with BCI is a first step, but those standards are not quantitative and are easy to skirt. They could also work with local governments to tighten environmental regulations that target water usage and water-system pollution. These efforts, and others, could further differentiate Levi Strauss beyond what they are doing today to fight climate change.<\/p>\n
