A public life cycle assessment of CO₂ dyeing technology is unavailable, but a private study has been carried out by DyeCoo Textile Systems BV [1] that compares CO₂ dyeing with industry averages of best available technology over the last seven years.

From this, Adidas claims that the dyeing of a conventional T-shirt requires 25 litres of water, whereas the dyeing of CO₂ dyed "DryDye" T-shirt requires none. In addition, CO₂ dyeing "uses 50% less energy and 50% fewer chemicals" [1]. This will reduce carbon emissions and waste water production.
