Polyester/cotton blends have a lower CO2 footprint [than 100% cotton]
When measuring the CO2 footprint from cradle to cradle, workwear made of a polyester/cotton blend emits 10% less CO2 than 100% cotton workwear. The figures below take the following into account: fibre production, production of fabric and garments, use and laundering, distribution and disposal
This brochure is based on a comprehensive Life Cycle Assessment published by the Danish Technical University.

Now a Master thesis doesn't strike me as the ultimate word on this matter (and it's also from two decades ago), so is the claim that polyester-cotton blends have lower CO2 footprint than pure cotton consistent with other studies on this matter?
