Greenwashing 101: How to Read a Sustainability Claim

If a brand puts a leaf on the packaging, you should probably distrust them more, not less. Here's a working checklist.

The Six Sins of Greenwashing

Researchers at TerraChoice catalogued how companies mislead. The classics are still everywhere:

1. Hidden trade-off. "Made with recycled paper!" (true) — but the paper is laminated with plastic and isn't recyclable.
2. No proof. "Eco-friendly" with no certification, lifecycle data, or detail.
3. Vagueness. "Clean," "natural," "green," "earth-conscious." None of these have a legal definition.
4. Irrelevance. "CFC-free!" — CFCs were banned in 1996.
5. Lesser of two evils. "Organic cigarettes." Sustainable single-use plastic.
6. Fibbing. Outright false claims. Rare, but they happen.

Words to distrust

These mean nothing without backup:

• "Clean"
• "Natural"
• "Eco" / "Eco-friendly"
• "Conscious"
• "Plant-based" (when describing packaging that's still plastic)
• "Biodegradable" (without a timeframe and conditions)
• "Recyclable" (without saying *where*)

Words to trust (a little more)

These have actual standards behind them:

• USDA Organic — defined ingredient list
• Cradle to Cradle Certified — full lifecycle assessment
• B Corp — verified social and environmental performance
• EWG Verified — ingredient transparency
• TÜV OK Compost INDUSTRIAL — certified to break down in industrial composting
• FSC — paper from responsibly managed forests

These aren't perfect — certifications have their own gaps — but they're a hundred times more meaningful than a leaf icon.

The five questions to ask

When evaluating a brand's sustainability claim, run through:

1. What specifically is sustainable? Formula, packaging, supply chain, all three?
2. Compared to what? "50% less plastic than our previous version" is useful. "Sustainable" alone isn't.
3. End-of-life? Recyclable curbside, or only at a special drop-off?
4. Verified by whom? Self-claimed or third-party?
5. Is the rest of the brand congruent? A "sustainable" line from a parent company that makes 99% disposable plastic is greenwashing the parent.

A real-world example

Brand A says: "Plant-based formula. Packaging is 100% PLA, certified TÜV OK Compost INDUSTRIAL. Composts in 12 weeks in industrial facilities. No microplastics in the formula."

Brand B says: "Conscious beauty. Clean. Eco-friendly packaging."

Brand A told you what, how, and how fast. Brand B told you nothing.

Why this matters

When greenwashing works, it siphons demand away from brands actually doing the work, and rewards brands doing the marketing. You vote with your spend. A few minutes of label-reading is one of the highest-leverage things you can do.
