The Problem With 'Eco-Friendly' Merch Claims
Only 1 in 5 consumers believe brands accurately communicate their sustainability efforts. The other four have been burned by vague promises and empty labels.
The merch industry has a greenwashing problem. Terms like "eco-friendly," "green," and "sustainable" get applied to products with no certifications, no specifics, and no accountability. Meanwhile, the fashion industry produces 92 million tonnes of textile waste every year and accounts for roughly 10% of global carbon emissions.
To compound the problem, 75% of consumers cannot correctly identify which of two products has a higher carbon footprint. The knowledge gap is real, and it is being exploited. This guide offers practical, honest information about what sustainable custom printing actually looks like.
Why Sustainable Merch Matters More Than Ever
Consumer expectations have shifted dramatically. According to Blue Yonder's 2025 survey of over 5,000 consumers, 78% of global shoppers now consider sustainability an important factor in their purchasing decisions. Among Gen Z, that figure jumps to 88%.
This is not just a B2C trend. In the corporate world, 69% of employees prefer sustainably made gifts and company swag. Among those aged 25 to 34, 70% say their opinion of a company improves when gifts are made with sustainability in mind. If you are ordering branded merch for your team, the materials matter as much as the logo.
The market reflects this shift. The sustainable clothing segment is valued at $10.09 billion globally and is projected to reach $24.99 billion by 2035, growing at a 9.49% CAGR. Demand is accelerating, not plateauing.
Regulations are catching up, too. The EU's Corporate Sustainability Reporting Directive (CSRD), rolling out through 2025 and 2026, is pushing brands to prove their sustainability claims with verifiable data. Making a claim is no longer enough; you need to back it up.
Overproduction accounts for 40% of global textile waste. Custom merch ordered in bulk, stored in a warehouse, and never distributed is a direct contributor to that statistic. The old model of ordering thousands of units "just in case" is not just financially wasteful; it is environmentally reckless.
Decoding Sustainability Certifications: What They Actually Cover
Not all certifications are created equal. Each one covers a different slice of the supply chain, and understanding those differences is critical to making informed decisions.
GOTS (Global Organic Textile Standard) is the gold standard for organic textiles. It covers the entire supply chain, from raw fibre harvesting through processing, manufacturing, and labelling, and includes social criteria like fair wages and safe working conditions. If a garment carries a GOTS label, it has been verified at every stage.
OEKO-TEX Standard 100 is often confused with GOTS, but it serves a very different purpose. OEKO-TEX tests the finished product for harmful chemicals, including heavy metals, formaldehyde, and pesticides. It does not certify organic farming practices or fair labour conditions. It tells you the product is safe to wear, not how it was made.
GRS (Global Recycled Standard) certifies the percentage of recycled content in a product and tracks the chain of custody from recycled input to finished good. GRS does not address labour practices or agricultural methods. It answers one question: how much of this product is actually recycled?
Fair Wear Foundation focuses exclusively on labour rights and factory working conditions, auditing factories for fair wages, reasonable working hours, and safe environments. It does not cover environmental impact.
FSC (Forest Stewardship Council) certification applies to paper-based packaging and printed materials, not garments. If your merch includes hang tags, boxes, or paper inserts, FSC certification ensures those materials come from responsibly managed forests.
The key takeaway: a truly sustainable product ideally combines multiple certifications. One certification alone rarely tells the full story. When evaluating a supplier, ask which certifications apply and to which part of the product they refer.
Printing Methods Ranked by Environmental Impact
The garment is only half the equation. How your design gets onto that garment matters just as much.
Embroidery is one of the most sustainable decoration methods available. No inks, no chemicals, no water waste. The result is durable and long-lasting, which means fewer replacements over time. If your design works as embroidery, it is worth serious consideration.
DTG (Direct-to-Garment) printing uses water-based inks applied directly to the fabric. It produces minimal waste, requires no screens or setup materials, and works on a per-order basis with no minimum quantities. The global DTG market is expected to grow from $3.2 billion in 2025 to around $9.1 billion by 2035, a 184% increase driven partly by sustainability demand.
Screen printing remains the industry workhorse, but its environmental profile depends heavily on the inks used. Traditional plastisol inks contain PVC and phthalates. Water-based alternatives exist and are significantly cleaner, but they remain less common than they should be. Always ask which ink type your printer uses.
Dye sublimation produces vivid, full-color results but requires polyester fabric. Polyester is petroleum-derived, takes 20 to 200 years to decompose, and sheds microplastics with every wash. Synthetic fibres from fashion account for 35% of all primary microplastic pollution in the ocean.
One additional detail worth noting: OEKO-TEX certified water-based inks can reduce water consumption and harmful chemical output by up to 60% compared to traditional plastisol inks. Ask your printer specifically which inks they use and whether those inks carry any certifications.
The Full Lifecycle of Sustainable Merch
Sustainability is not a single attribute. It spans every stage of a product's life: raw materials, printing, packaging, shipping, and end-of-life disposal.
Raw materials: It takes approximately 2,700 litres of water to produce a single conventional cotton T-shirt, roughly 2.5 years of drinking water for one person. Organic cotton and recycled fibres dramatically reduce this footprint. Yet only 8% of textile fibres in 2023 came from recycled sources. Choosing recycled-content garments is a meaningful differentiator, not a marginal one.
Packaging: According to Shorr's 2025 survey of over 2,000 U.S. consumers, 90% are more likely to purchase from a brand with eco-friendly packaging. Ask about recycled poly mailers, plastic-free options, and compostable bags. By 2030, an estimated 60 to 70% of packaging print decisions are expected to be sustainability-led.
Shipping: Where your order is produced matters. Local or regional production hubs reduce carbon emissions from international fulfillment. If your printer manufactures overseas and ships globally, the transportation footprint can undermine the sustainability of the product itself.
End-of-life: Natural fibres like organic cotton biodegrade. Synthetic blends persist in landfills for centuries. The material choice you make today determines the waste legacy decades from now.
Print-on-demand as a structural solution: Made-to-order production eliminates deadstock entirely. No overproduction, no unsold inventory sitting in warehouses, no bulk orders destined for landfill. Given that overproduction causes 40% of textile waste, the print-on-demand model addresses one of the industry's biggest problems at a structural level.
Your Greenwashing Red Flags Checklist
Use this checklist to evaluate any supplier's sustainability claims before you order:
- Vague language: Terms like "eco-friendly," "green," or "sustainable" with no named certifications or specific materials listed.
- Stock imagery of nature: Forests, leaves, and green color palettes with no verifiable supply chain information behind them.
- No third-party certification logos, or logos that link to no verification page when clicked.
- "Carbon neutral" claims without a named offset partner, methodology, or third-party audit.
- "Recycled" claims without specifying the percentage of recycled content or providing GRS certification.
- No transparency about where garments are manufactured or where printing is fulfilled.
If a supplier triggers multiple items on this list, proceed with caution. Legitimate sustainability is specific, verifiable, and documented.
Questions to Ask Your Custom Printer Before You Order
These questions will help you separate genuine sustainability practices from surface-level marketing:
- What certifications do your blank garments carry? Specifically, are they GOTS, OEKO-TEX, or GRS certified?
- What type of inks do you use, and are they OEKO-TEX certified or water-based?
- Where are garments manufactured, and where is printing fulfilled?
- Do you offer plastic-free or recycled packaging options?
- Is production made-to-order, or do you hold pre-printed inventory?
- Can you provide a carbon impact estimate or transparency report for my order?
Suppliers with genuine sustainability practices will answer these questions readily and with specifics. Those making surface-level claims will deflect, generalize, or go silent. The questions themselves are the filter.
How to Choose Sustainable Custom Merch That Actually Delivers
The decision framework is straightforward: evaluate certifications, understand the printing method, consider the full lifecycle, and verify transparency at every step.
The sustainable clothing market is growing fast, and suppliers are responding with better options every year. In April 2024, TPOP launched a full carbon-neutral custom apparel range using GOTS-certified organic cotton and OEKO-TEX certified water-based inks, complete with a per-order carbon impact transparency tool. This is the direction the industry is heading.
Consumer willingness to pay supports the shift. Research from Bain and Company shows that 80% of consumers will pay more for eco-friendly products, with an average premium tolerance of around 12%. Sustainability is not a cost center; it is a value proposition.
Treat sustainability as a supply chain question, not a marketing label. Ask for specifics. Demand documentation. Choose suppliers who can show you their certifications, explain their processes, and tell you exactly where your product is made.
EU CSRD and broader ESG regulations mean that sustainable sourcing is becoming a business requirement, not just a preference. Brands ordering custom merch today need to future-proof their choices for a regulatory environment that will only get stricter.
At Varaprint, we believe transparency is the foundation of genuine sustainability. We encourage you to ask us, and every supplier you evaluate, the hard questions outlined in this guide. That is how the industry gets better, one informed order at a time.
