Given that the clothing business is predicted to grow to $2.25 trillion by 2025, the fashion sector has a substantial impact on the world economy. Its impacts on the environment, particularly its use of water, are alarming, though. The industry uses 93 billion cubic meters of water annually and contributes around 20% of the world’s wastewater. Understanding fashion’s water footprint is essential for businesses and consumers to support sustainable practices in an era of growing water shortages.

Understanding Water Footprint

Including both direct and indirect water use along the supply chain, the phrase “water footprint” describes the overall amount of freshwater utilized to generate goods and services. This includes everything from cultivating cotton crops to dying textiles and completing clothing in the fashion sector.

1. Direct Water Use

Recent estimates place the annual water use of the textile sector at about 79 billion cubic meters, with dyeing and washing accounting for a sizable amount of this total. For example, 50 to 100 liters of water are needed for every kilogram of cloth produced just for the dyeing process. Many manufacturers are now using water-efficient technology in response to growing environmental concerns. These technologies can help businesses lessen their ecological impact by reducing their direct water use by up to 30%.

2. Indirect Water Use

When all stages of the production process are taken into account, from cultivation to processing, it is estimated that 10,000 to 20,000 liters of water can be used to produce 1 kilogram of cotton. Over 90% of a product’s overall water use is frequently attributed to its invisible water footprint. Brands are spending more money on recycled materials and certified organic cotton as a result of the increased awareness of sustainable practices. These investments can significantly reduce the indirect water consumption related to textile production.

The fashion industry is often heavily dependent on the use of water, which causes extreme impacts in regions suffering from water scarcity. For instance, approximately 7,500 liters of water are consumed to produce one pair of jeans, an environmental cost that is stunningly disproportionate to the low price of the garment.

The Water Footprint of Raw Material Production

Different materials have varying water footprints, influencing their environmental impacts and sustainability.

a. Cotton

One kilogram of a traditional cotton t-shirt requires roughly 10,000 liters of water, making cotton a crop that uses a lot of water. In nations like India, where water stress is already a problem, this is a major problem. Supporting organic cotton is a step in the direction of sustainability because it consumes less water and fewer pesticides.

b. Polyester

The production of polyester, a synthetic textile derived from petrochemicals, also uses a significant amount of water—roughly 200 liters per kilogram. Despite using less water than cotton, polyester’s production process uses a lot of energy and can lead to microplastic contamination, which has a big impact on marine ecosystems.

c. Wool

The water footprint of wool must also be carefully considered, particularly when it comes to sheep farming methods. More than 171,000 liters of water are typically used to produce one kilogram of wool. The overall effect is greatly influenced by elements such as animal care and grazing methods.

d. Leather

Cattle leather manufacture uses a significant amount of water—on average, 15,000 gallons for every kilogram produced. The procedures of tanning and rearing animals are the causes of this high usage. Concerns regarding land use, deforestation, and greenhouse gas emissions are also brought up by the manufacture of leather, which affects sustainability in general.

e. Hemp

Hemp is a sustainable fiber with a very low water footprint of less than 600 liters per kilogram, needing less water than cotton and growing in various climates. It contributes to soil improvement and requires fewer pesticides and fertilizers, making it an eco-friendly fiber. Further, hemp contributes to a versatile, sustainable textile industry.

The Manufacturing Process and Water Use

Beyond just raw materials, the fashion industry’s water footprint is greatly influenced by a number of manufacturing processes. It is necessary to comprehend their contributions in order to promote more sustainable activities.

• Dyeing Processes use up to 200 liters of water per kilogram of fabric, and this huge consumption is adding significant costs to pollution.
• Environmental Laws: A lot of dyeing plants are located in places with lax laws, which results in hazardous runoff that taints nearby water supplies.
• Water-Efficient Technologies: Water consumption in dyeing may be greatly decreased by implementing techniques like digital printing and dry dyeing.
• Finishing Treatments: Various washing and finishing cycles pose quite a burden on the environment, sometimes overweighing that of the basic material.

Strategies to Reduce Water Footprint in Fashion

Due to awareness of related environmental impacts being generated in the fashion sector, several other ways can be employed to reduce water consumption and pollution.

1. Sustainable Practices

Brands should implement water-efficient practices throughout their supply chains. This means implementing better irrigation practices and using cotton-growing materials with less water footprints.

2. Recycling and Circular Fashion

The overall water footprint can be considerably decreased by promoting circular fashion, in which items are made to last and eventually be recycled. Businesses can reduce their need for new materials by urging consumers to recycle their old clothes and purchase used goods.

3. Innovative Water Management

Water waste can be reduced by putting water management systems into practice. Additionally, sophisticated filtering systems can aid in purifying dyeing water so that it can be used repeatedly.

4. Consumer Education

Demand for more environmentally friendly products may increase if customers are made aware of how the clothes they buy affect the environment. This type of shift in consumption patterns might be made possible by awareness campaigns and projects aimed at improving industry standards.

5. Collaboration and Transparency

An initiative that may actually help firms push supply chain transparency and sustainable sourcing is the Transparency in Supply Chains Act of 2010, which obliges the firm to take greater responsibility for its environmental impact.

Conclusion

Consumers, brands, and legislators must all take action to address the fashion industry’s water footprint. Fast fashion is not sustainable because it uses a lot of water to produce raw materials and clean clothing. The industry may lessen its impact on water by adopting sustainable practices and encouraging openness. A more responsible fashion industry that strikes a balance between environmental stewardship and profitability can be fostered by raising customer knowledge.
