Material Cultivation
- Cotton cultivation uses 222 billion cubic meters of water annually
- Conventional cotton requires about 10,000 liters of water to produce 1 kilogram of fiber
- Organic cotton has the potential to reduce water consumption by 91% compared to conventional cotton
- 69% of the water footprint of the textile industry is related to agriculture (cotton farming)
- Leather production requires up to 17,000 liters of water per kg of leather produced (farming + tanning)
- Flax (Linen) requires roughly 6.4 liters of water to produce one shirt, significantly less than cotton
- Hemp consumes about 50% less water than cotton per season
- Viscose production is linked to water-intensive eucalyptus plantations affecting water tables
- Rain-fed cotton accounts for only 47% of global production; the rest relies on intense irrigation
- Polyester production requires less water than cotton (approx. 71 liters per kg for cooling), but more energy
- Lyocell (Tencel) production uses 20 times less water than cotton cultivation
- Wool production has a water footprint of 142,000 liters per kg if including feed irrigation (Green Water)
- 57% of cotton is grown in areas with high or extreme water stress
- In the Aral Sea region, 1.4 million hectares of river drying was caused by cotton irrigation
- BCI (Better Cotton Initiative) farmers used 22% less water on average in Pakistan
- Creating 1kg of cow leather for fashion utilizes 17,093 liters of water (global average)
- Cultivating 1kg of bast fibers (like Jute) requires around 174 liters of irrigation water

Interpretation
The fashion industry is guzzling water on an industrial scale, with conventional cotton and leather demanding thousands of liters per kilogram and even helping to dry river basins like the Aral Sea, while linen, hemp, lyocell, organic and recycled fibers can slash that footprint—so the smartest trend to follow is water conscious sourcing and design.
