The water footprint has a significant impact on sustainability in textile production because the industry is one of the most water-intensive in the world. From the cultivation of raw fibers to the finishing of the finished fabrics, large amounts of water are used at every stage of production. The following sections address the most important questions regarding water consumption, environmental impact, and specific reduction measures.<\/p>\n
Textile production consumes enormous amounts of water worldwide. It is estimated that a single cotton T-shirt requires 2,000 to 2,700 liters of water, and a pair of jeans can require as much as 8,000 liters. This makes the textile industry one of the most water-intensive sectors of all, even ahead of many other manufacturing industries.<\/p>\n
Water demand does not arise in just one place, but accumulates throughout the entire supply chain. The largest share comes from raw fiber cultivation, particularly cotton, which, as a crop that requires irrigation, consumes a great deal of water. Added to this are the process steps in spinning, weaving, dyeing, and finishing, where water is used as a solvent, transport medium, and coolant. Anyone looking to reduce water consumption in the Textile industry<\/a> Anyone who wants to understand this must therefore keep the entire value chain in mind.<\/p>\n The three most water-intensive stages in textile production are raw fiber cultivation, wet finishing, and dyeing and finishing. Together, they account for the lion's share of the total water footprint. All three stages differ significantly in the way they use and impact water resources.<\/p>\n Cotton is the most water-intensive natural fiber. In growing regions such as Central Asia, India, and the United States, it is primarily irrigated. Cotton\u2019s water requirements exceed those of other fibers, such as linen or hemp, by a wide margin. The drying up of the Aral Sea in Central Asia is considered one of the best-known examples of the consequences that intensive cotton cultivation can have on regional water resources.<\/p>\n In wet finishing, textiles are washed, bleached, dyed, and treated with functional finishes. Each of these steps requires large amounts of water, which is also contaminated with chemicals. The dyeing process, in particular, is considered critical: unused dye residues and auxiliary chemicals often end up in wastewater and significantly pollute water bodies in producing countries. This is where a large portion of the so-called gray water footprint originates.<\/p>\n The water footprint is divided into three categories: blue represents surface water or groundwater consumed, green represents rainwater used, and gray represents the volume of water needed to dilute pollutants in wastewater to an acceptable level. These three categories help provide a nuanced assessment of water consumption.<\/p>\n For a comprehensive sustainability assessment in sustainable textile manufacturing, all three categories must be considered together, not just visible water consumption.<\/p>\n A high water footprint in textile production harms local ecosystems, depletes drinking water resources in regions that are already water-stressed, and creates risks throughout the entire supply chain. Companies that rely heavily on production in water-stressed regions also expose themselves to regulatory and reputational risks.<\/p>\n From an environmental perspective, excessive water extraction leads to falling groundwater levels, the drying up of wetlands, and damage to ecosystems. Wastewater from textile production that is discharged untreated into waterways contaminates drinking water sources and endangers the health of people in the region.<\/p>\n At the supply chain level, water scarcity creates risks: When production sites no longer have sufficient access to water, production disruptions occur. In addition, international regulations such as the EU\u2019s supply chain due diligence requirements are increasing the pressure on companies to actively manage water risks in their supply chains and report on them transparently.<\/p>\n Water consumption in textile production can be significantly reduced through a combination of technical innovations, improved use of raw materials, and intelligent process control. Many of these measures pay off not only environmentally but also economically.<\/p>\n Textile companies measure their water footprint using internationally recognized methods such as the Water Footprint Assessment based on the Water Footprint Network standard or the ISO 14046 standard. These methods track water consumption throughout the entire supply chain and break it down into blue, green, and gray water components.<\/p>\n For data collection, production data from the individual manufacturing stages is gathered, supplemented with consumption figures from supplier audits and databases, and then consolidated into a comprehensive overview. Without a structured database of in-house production data, reliable measurement is virtually impossible. This is where it pays off for companies that already have a comprehensive digital system in place for recording their operational data, for example through Operational Data Collection<\/a>.<\/p>\n Reporting often takes place as part of sustainability reports prepared in accordance with GRI (Global Reporting Initiative) standards or as part of ESG reports. More and more companies are required by regulatory mandates such as the EU Taxonomy or the Corporate Sustainability Reporting Directive (CSRD) to transparently disclose their water consumption and water risks. Companies that collect reliable data early on have a clear advantage when it comes to meeting these reporting requirements.<\/p>\n Sustainability in textile production begins with transparency regarding one\u2019s own processes.
