Conventional cotton
A natural fibre with an outsized pesticide, water and forced-labour footprint unless certified.
Also listed as: non-organic cotton, BCI cotton, '100% cotton'
What it is
Conventional cotton is grown from treated, often GM seed with heavy synthetic inputs, then ginned, spun and dyed through supply chains that frequently cross five or more countries before the garment is sewn.
Why it's worth avoiding
The impact sits upstream where no consumer can see it: irrigation drawdown, pesticide exposure for farm workers, effluent from dye houses, and — in some regions — state-imposed labour.
What the evidence says
Cotton accounts for roughly 4.7% of global pesticide sales on about 2.4% of arable land (Pesticide Action Network). Xinjiang produced around 20% of world cotton before import bans over forced-labour findings.
How it's regulated
The US UFLPA presumes goods with Xinjiang inputs are made with forced labour and bars import unless rebutted. The EU's forced-labour regulation adopted in 2024 introduces a comparable market ban.
Label clues
- '100% cotton' with no GOTS, OCS, Fairtrade or regenerative certification
- No country of origin or spinner named anywhere on the site
- Very low price points with high color saturation
- 'Cotton blend' hiding a majority-polyester composition
Safer swaps
- GOTS-certified organic cotton with a licence number
- Recycled cotton (GRS) for lower-input basics
- Hemp, linen or lyocell for durability with lower irrigation
- Secondhand and deadstock, which add no new farming impact
Where it shows up
Frequently asked
Is BCI cotton the same as organic?+
No. Better Cotton is a mass-balance improvement programme without an organic input ban, and the fibre in your garment may not be Better Cotton at all. GOTS certifies the physical product.
Is recycled cotton as good as organic?+
For impact per kilo, often better — no new farming. Fibre length is shorter, so it is usually blended, which can complicate future recycling.

How to spot Conventional cotton on a label
Conventional cotton rarely appears under that exact name on packaging. Manufacturers use trade names, umbrella terms such as "fragrance" or "performance finish", or simply omit process chemicals that are not classed as intentional ingredients. That is why reading a claim ("free from", "non-toxic", "natural") tells you far less than reading the composition and the certifications behind it.
The practical approach is to work backwards from certifications that test finished products rather than from ingredient lists alone. A scheme with residue limits and third-party lab testing catches substances that a marketing claim will never mention, including contamination introduced during dyeing, coating or packaging.
Exposure also depends on use. The same substance matters much more in something worn against skin all day, heated, chewed, or used on broken skin than in a rigid object handled briefly. Judge risk by contact, duration and temperature, not by the scariness of the name.
Claim vs. verification
| What you see | What it proves | What to do |
|---|---|---|
| “Free from” on the front of pack | Nothing verifiable on its own — unregulated wording | Look for a named standard or test method |
| Full ingredient or fibre list | Intentional inputs only, not process residues | Cross-check against a residue-tested certification |
| Third-party certification | Audited limits, usually with lab testing | Confirm scope, product line and expiry date |
| Published test report | Strongest evidence available | Check the lab, the date and the method used |
Safer-swap checklist
- Prefer residue-tested schemesOEKO-TEX, GOTS and equivalents set limits and test finished goods.
- Cut the coatingsStain-, water- and wrinkle-resistant finishes are the most common carriers of unwanted chemistry.
- Mind the heatHeat and abrasion increase migration; choose plainer materials for anything hot or worn.
- Ask for the certificateA brand that holds one will send the number; a brand that does not will change the subject.
