Cotton Vs. Hemp: Water Demand

The Stockholm Environment Institute published a major 39-page report in 2015 that compared the ecological footprint of various fibers. In terms of water consumption, each kilogram of cotton requires 9,758 kilograms of water use, compared to as little as 2,401 kilograms for each kilogram of hemp. Estimates suggest that growing cotton requires 2 to 5 times more water than growing hemp.
