Sustainability claims in the promotional products and custom apparel industry range from genuinely meaningful to almost entirely decorative. "Eco-friendly," "green," and "sustainable" are applied to products that span from properly certified organic textiles to items that are marginally less harmful than their conventional equivalent and marketed aggressively for it.

Here's how to tell the difference, and what to actually look for if sustainability matters to your brand or event.

The greenwashing problem

A product being described as "eco" or "sustainable" tells you almost nothing without certification or specifics. Cotton grown with conventional pesticides and dyed with synthetic chemicals can be described as "natural." A plastic bottle made from 10% recycled content can be called "recycled." A product manufactured in a facility with no environmental standards can ship in recycled packaging and be marketed as a "green choice."

The question to ask isn't "is this described as sustainable?" It's "what specifically makes this more sustainable than the alternative, and is that claim verified by a third party?"

Certifications that actually mean something

GOTS (Global Organic Textile Standard) is the most rigorous certification for organic textiles. It covers the entire supply chain — from raw fibre through dyeing and finishing to final product — and requires that at least 70% of fibre content is certified organic. It also covers social criteria (fair labour conditions). A GOTS label on a garment means the organic claim has been independently verified at every stage. This is the gold standard.

OEKO-TEX Standard 100 certifies that a product has been tested for harmful substances and is considered safe for human use. It doesn't certify that the product is made from organic or recycled materials — it certifies that it doesn't contain dangerous chemicals. This matters for safety and is a meaningful certification, but it's not the same as a sustainability certification.

Better Cotton Initiative (BCI) supports more sustainable cotton farming practices but doesn't require organic certification. It's a step up from conventional cotton in terms of water and pesticide use, but not as rigorous as GOTS. Many mainstream brands source BCI cotton and it's a legitimate (if more modest) claim.

Recycled claim standards (GRS — Global Recycled Standard): For recycled content — particularly recycled polyester made from plastic bottles — the GRS certifies that the recycled content claim is accurate and traces the material through the supply chain. Look for GRS certification on products claiming to be made from recycled materials.

Materials worth understanding

Organic cotton (GOTS certified): Grown without synthetic pesticides or fertilisers. Uses less water than conventional cotton in many (though not all) growing systems. Genuinely more sustainable than conventional cotton if certified. Available in tees, tote bags, and some fleece products. Costs more per unit — typically 20–40% above comparable conventional cotton.

Recycled polyester (rPET): Made from post-consumer plastic bottles or other recycled plastic. Reduces virgin plastic demand and diverts waste from landfill. Widely available in performance fabrics, bags, and some branded apparel. A meaningful improvement over virgin polyester with GRS certification to back the claim.

Bamboo: Heavily marketed as sustainable, the reality is more complicated. Bamboo grows rapidly and requires no pesticides in its natural state — that part is true. But converting bamboo into soft fabric requires significant chemical processing, and most "bamboo fabric" is technically bamboo-derived viscose/rayon. The sustainability of the end product depends heavily on how the processing is managed. Not inherently greenwashed, but the claims are often overstated.

"Recycled" products with minimal recycled content: A product described as made from recycled materials should tell you the percentage. 100% recycled is very different from 20% recycled. Anything under 50% recycled content as the primary sustainability claim is worth scrutinising.

Practical options in Australia

Stanley/Stella, Continental Clothing, and Earth Positive offer GOTS-certified organic cotton blanks available through Australian decorators. AS Colour offers some GOTS and recycled options in their range, though it's not their primary focus. For tote bags, organic canvas options are available from several promotional product suppliers and can be decorated via screen print or embroidery in the same way as conventional canvas.

The honest bottom line

If sustainability is genuinely important to your brand or event audience, look for GOTS certification on cotton products and GRS certification on recycled materials. Be prepared to pay a modest premium. Don't rely on marketing language alone — ask for the specific certification before committing.

If sustainability is a secondary consideration and you're primarily looking for a product that's "a bit better" without the full premium, BCI cotton and products with verified recycled content are reasonable middle-ground choices.

What's not worth doing: choosing a product because it's labelled "eco" without understanding what that means, then communicating that claim to your audience. In an environment where greenwashing is increasingly scrutinised, a vague sustainability claim is worse than no claim at all.
