The word "sustainable" gets stamped on everything from t-shirts to sneakers, but a label on a hangtag doesn't tell you much on its own. Greenwashing thrives on vague language and good intentions, so the only real way to separate a genuinely responsible brand from a well-marketed one is to ask sharper questions. Here are ten worth running through before you decide a brand deserves the label.
1. Does the brand publish where its products are made? A truly transparent company can name the factories, regions, or at least the countries involved in production. If sourcing information stops at "ethically made" with no further detail, that's a red flag rather than a reassurance.
2. Can the brand show how it pays the people making its clothes? Sustainability isn't only about materials, it includes the wages and working conditions of garment workers. Look for specifics on living wage commitments and independent audits rather than general statements about "fair treatment."
3. What percentage of the collection is actually made from lower-impact materials? A brand might highlight one capsule collection made from organic cotton while the rest of its catalog uses conventional synthetics. Ask for the proportion of the full range, not just the marketing highlight.
4. Are the certifications real and verifiable? Logos like GOTS, OEKO-TEX, or Fair Trade carry weight because they involve independent verification. A brand that references "eco-friendly standards" without naming a certifying body is likely relying on the feeling of credibility rather than the substance of it.
5. Does the brand disclose its supply chain beyond the final stitching? Many garments pass through spinning, dyeing, and finishing stages before assembly, and each step carries its own environmental footprint. Full traceability, not just the last link in the chain, is what separates real transparency from selective storytelling.
6. Is there a repair program or guidance for extending a product's life? Brands serious about reducing waste often provide repair services, spare parts, or care instructions designed to keep garments in use longer. The absence of any repair option suggests the business model still depends on frequent replacement.
7. What happens to returned or unsold stock? Ask whether returned items are resold, donated, recycled, or destroyed. Some retailers have been found quietly discarding unsold inventory, which undercuts any sustainability claim made on the shop floor.
8. Does the brand set measurable targets with deadlines? Statements like "committed to a greener future" mean little without numbers attached. Look for specific goals, such as a percentage reduction in emissions by a stated year, along with regular progress reporting.
9. How does the brand handle packaging and shipping? Sustainability claims that stop at the product itself but ignore plastic mailers, excess packaging, or shipping practices are only telling part of the story.
10. Would the brand's claims hold up if a customer asked for the data behind them? This is the simplest test of all. A brand confident in its practices will usually welcome scrutiny and provide sources, reports, or third-party verification. One that responds with vague reassurance is often hoping the conversation ends there.
Worth flagging specifically: claims like "climate neutral," "carbon neutral," or "carbon positive" that rely mainly on offsetting rather than real reductions are a classic greenwashing tactic. Under the EU's Empowering Consumers for the Green Transition Directive, these kinds of unsubstantiated neutrality claims become explicitly banned across the bloc from September 2026, alongside vague generic terms like "eco-friendly" used without proof. Any brand still leaning on offsets as its main sustainability pitch is worth an extra dose of skepticism.
Running a brand through these ten questions won't give a perfect score, but it will separate genuine effort from marketing polish. Sustainability is rarely all-or-nothing, and most companies are somewhere in the middle of a long transition. The goal isn't to find a flawless brand, it's to reward the ones being honest about where they stand and where they still have work to do.
