When I first started researching fabrics for what would later become Treehouse, I knew that the very basic starting point for me would be cotton, but not just any cotton, and let me explain why.
Let’s start with the simple part: yes, cotton is a renewable resource. It comes from a plant that can be regrown year after year. But here’s the catch: renewable doesn’t always mean sustainable. How cotton is grown, processed, and dyed can completely change its environmental and health impact. And that matters.
So if you’ve ever wondered whether cotton is truly a good choice for your kids and the planet, let’s break it down properly, no fluff, no greenwashing, just facts every parent should know.
How Cotton Is Made
Before we decide if cotton is “good,” it helps to understand what it actually takes to turn a fluffy white plant into the soft fabric in your child’s t-shirt.
Cotton is grown in warm climates, such as India, the U.S., China, and Turkey. The plant’s seeds produce the fluffy fiber we know as the cotton boll. Once harvested, those fibers go through ginning (removing seeds), then spinning (turning fibers into yarn), and finally weaving or knitting (to make fabric).
The last stage, finishing, is where the biggest red flags appear. This is when conventional cotton is often bleached, softened, and dyed, sometimes with formaldehyde-based resins or heavy-metal dyes that can linger in the final product. That’s why not all cotton is created equal, and why certifications matter so much.
What “Renewable” Really Means, And Why It’s Only Part of the Story
“Renewable” simply means something can grow back within a human lifetime, wood, wool, bamboo, or cotton. But that’s just biology. It says nothing about how responsibly it’s produced or what it means when worn on our skin.
Cotton plants regrow each year, so yes, they’re renewable. But the farming methods used to grow them can either nurture the soil or destroy it. A field drenched in synthetic fertilizers and pesticides is technically renewable, but not remotely sustainable.
Think of it this way: sugar is “natural,” too, but that doesn’t mean eating a bowl of it for breakfast is healthy. The same logic applies to cotton. It’s not just what it is, but how it’s made that matters.
Environmental Impacts of Cotton Production: What to Watch For
Even though cotton is renewable, its environmental footprint depends entirely on how it’s cultivated and processed. For parents who care about both their child’s health and the planet’s, here’s what you should know.
Water Usage in Cotton Production
Cotton is one of the thirstiest crops on earth. According to the International Science Council, it can take around 2,700 liters of water to produce one t-shirt, enough for a person to drink for 2.5 years.
That number isn’t the same everywhere: cotton grown in dry regions like Pakistan or parts of India relies heavily on irrigation, while in rain-fed areas like Brazil, the impact is lower.
Organic cotton, however, uses up to 90% less blue water (the kind diverted from rivers and lakes) thanks to healthier soil that retains moisture better and a total ban on toxic fertilizers that degrade water systems.
Pesticides, Fertilizers, and Soil Health
Conventional cotton farming accounts for up to 16% of the world’s insecticide use, more than any other crop (World Wildlife Fund). These chemicals don’t just affect pests; they harm the farmers applying them, poison waterways, and reduce biodiversity.
For children, residues from these substances can linger in finished clothing and irritate sensitive skin.
Organic cotton farming bans synthetic pesticides and relies instead on composting, crop rotation, and beneficial insects to manage pests naturally, building healthier soil and safer fibers from the ground up.
Land Use in Cotton Farming
Cotton takes up about 2.5% of the world’s farmland, and in some areas it competes directly with food crops for space and water. That’s where sustainability comes in again: organic cotton fields often integrate crop rotation, which restores soil nutrients and allows more efficient use of land.
As a parent, you can think of it this way: every time you choose organic cotton, you’re voting for soil that stays fertile, farmers who aren’t exposed to toxins, and a planet that can keep growing what our kids will need tomorrow.
Organic Cotton vs. Conventional Cotton: The Differences That Matter
You’ve probably seen “100% cotton” on a tag and assumed that meant safe. Sadly, that’s not always true.
Conventional cotton can still be genetically modified, sprayed with chemicals, and dyed with substances banned in baby products in other parts of the world.
Organic cotton, on the other hand, is grown without GMOs or synthetic pesticides, uses less water, and must meet strict social and environmental standards under certifications like GOTS (Global Organic Textile Standard).
A 2014 Life Cycle Assessment found that organic cotton has 46% less global warming potential than conventional cotton. And the difference is visible: when I visited our suppliers in India, one organic field buzzed with life, butterflies, insects, and cover crops. The conventional field beside it looked silent and gray. That moment changed everything for me.

Certifications & “Better Cotton” Programs, What to Trust
With so many “eco” labels floating around, it’s no wonder parents feel confused. Here’s what actually means something:
-
GOTS (Global Organic Textile Standard): The gold standard. Covers both environmental and social criteria from seed to finished product, from no GMOs or harmful dyes to fair wages.
-
OEKO-TEX® Standard 100: Tests the finished fabric for toxic residues.
-
Fairtrade Organic: Focuses on fair wages and community development.
-
BCI (Better Cotton Initiative): Improves practices but still allows synthetic inputs, so better than conventional, but not organic.
At Treehouse, our fabrics are both GOTS-certified and OEKO-TEX® tested, so they meet the highest safety standards for your child’s skin and the planet.

Circularity: Can Cotton Be Recycled or Biodegraded?
Cotton’s other advantage is its end of life. It’s biodegradable, and pure cotton can break down in compost in a few months. But there’s a catch: if it’s blended with polyester or finished with synthetic coatings, it no longer composts cleanly.
Cotton can also be mechanically recycled, though each cycle shortens the fibers, meaning recycled cotton often needs to be mixed with new fibers for strength. Still, it’s a promising path toward circular fashion, especially for kids’ clothes that are quickly outgrown.
Practical Takeaways for Parents
If you’re trying to make more mindful choices, here’s where to start:
When buying:
-
Look for GOTS-certified organic cotton.
-
Avoid “wrinkle-free” or “easy-care” claims; they usually mean chemical coatings.
-
Choose undyed or options dyed with GOTS-certified dyes.
-
Support small brands that publish their sourcing (yes, that matters).
-
Buy fewer, better-made basics that can be passed down.
When caring for cotton:
-
Wash on cold, it saves energy and protects fibers.
-
Skip fabric softener; a bit of vinegar in the rinse works wonders.
-
Line dry when possible.
-
Mend small holes and donate what still has life.
