The clothing you wear has a larger price tag than what you see when it's hanging on the rack—it comes with costs to the environment, too. Unsustainable dyeing and processing practices in the fashion industry have had a major impact on water pollution. So, as part of the Detox Catwalk campaign, Greenpeace spent three years cataloging which major fashion brands deliver on their green promises and which are doing the bare minimum.

Phthalates, used particularly in plastic printed images like those on printed T-shirts, have been linked to all sorts of health problems like asthma and lowered IQ.

The main types of chemicals Greenpeace is calling for clothing companies to stop using are alkylphenol etheoxylates (APEOs), phthalates and PFCs. Many companies have set "acceptable limits" on APEOs, but because these harmful chemicals accumulate in nature, limits don't fix the problem. Phthalates, used particularly in plastic printed images like those on printed T-shirts, have been linked to all sorts of health problems like asthma and lowered IQ. PFCs are used in stain-resistant clothing and have been tied to thyroid damage.

As a result of its analyses, Greenpeace assigned brands one of three rankings: Detox Leaders, Greenwashers and Detox Losers.

Greenpeace has just been looking at major players to make the largest impact, but there are plenty of smaller companies that have already established that their clothing is sustainable by going organic. Essentially, the GOTS certification is to clothing what the USDA Organic certification is to food. For instance, it ensures that cotton is grown organically and dyed using sustainable practices.
