Why Your Sustainability Report Isn't Enough Anymore: What Buyers Are Now Asking For

Publishing a sustainability report used to be enough to satisfy procurement teams. It isn't anymore. This post covers the shifts that have changed what buyers actually ask for — from commitments to verified evidence, from theoretical recyclability to real end-of-life outcomes, and from vague claims to lifecycle assessment data. It also addresses the microplastics question, which has moved rapidly up the procurement agenda. Brands that can answer the new questions with specificity win. Brands still leading with directional language are losing procurement decisions to those who can.

Not long ago, having a sustainability report was enough. You published one, it said the right things about your carbon commitments and your packaging targets, and buyers ticked their compliance box and moved on. That era is ending faster than most brands realise.

The buyers asking the new questions aren't necessarily more ideologically committed to sustainability than their predecessors. They're responding to a different set of pressures — incoming legislation, investor scrutiny, their own customers' expectations, and a growing awareness that vague sustainability claims create real legal and reputational risk. They've learned to ask harder questions, and they know which answers are real.

What Buyers Actually Want to See Now 

The first shift is from commitments to evidence. A sustainability report that says "we are committed to reducing our packaging footprint by 2030" used to satisfy procurement teams. Now those same teams want to know:

• What is the actual footprint today, in numbers?

• What was it last year?

• What specific material or process changes are driving any reduction?

• How are those changes being verified by a third party?

For packaging specifically, this means having lifecycle assessment data — actual numbers on carbon emissions per unit, material weight, and end-of-life breakdown rates. Buyers are increasingly asking for third-party verified LCA data, not internal estimates. If you don't have it, getting it is worth treating as urgent. If your packaging supplier can't provide it, that gap is itself something worth paying attention to.

For DTC brands specifically, the compliance miscalculation is one of the most common and costly packaging mistakes made at scale. [What DTC Brands Get Wrong About Sustainable Packaging at Scale] covers that and the other four places where sustainable packaging decisions tend to break down as volumes grow.

The End-of-Life Question

The second shift is around end of life. For years, "recyclable" was the gold standard sustainability claim for packaging. It's no longer sufficient, partly because buyers understand the gap between theoretical recyclability and actual recycling rates, and partly because EPR legislation has changed the financial calculus around different end-of-life categories significantly.

The questions you should be ready to answer with real data:

• What happens to this packaging at end of life under actual real-world conditions, not ideal ones?

• What percentage of it actually gets recycled, composted, or biodegraded in practice?

• What EPR category does it fall into in each market you sell into?

• What will that cost the buyer over meaningful volume?

Brands that can answer these questions confidently — with numbers, not intentions — are in a materially stronger position than those who can't. For brands still using EPS, the EPR and landfill cost implications are worth understanding in detail. [The Hidden Cost of EPS: Landfill Fees, EPR Contributions, and Returns from Damaged Product] covers exactly what that picture looks like.

The Microplastics Problem

A specific end-of-life concern that has moved rapidly up the procurement agenda is microplastics. Legislation targeting microplastic contamination is developing in multiple markets simultaneously, and buyers, particularly in food, beauty, and consumer goods, are increasingly asking whether their packaging sheds microplastics into the supply chain or the environment during degradation.

EPS and conventional plastic foam packaging breaks into microplastic fragments as it degrades. This isn't theoretical — it's documented, measurable, and increasingly regulated. Bio-composite materials made from natural fibres and bio-resins produce no microplastics and leave no toxic residue when they biodegrade. That's a straightforward answer to a question that's increasingly hard to answer with conventional materials.

What Convinces a Buyer These Days 

Buyers who are asking the new questions aren't expecting perfection. They're expecting honesty, specificity, and a credible direction of travel backed by evidence. The answers that land well share a few qualities:

• Quantified rather than directional

• Third-party verified rather than self-reported

• Addressing the full lifecycle rather than just the production phase

• Honest about the gap between current performance and stated goals

The answers that don't land are the ones that repackage vague commitments as data, cite recycling rates that don't reflect real-world outcomes, or claim sustainability credentials for materials that carry known environmental liabilities.

Your sustainability report is still worth publishing. But treat it as the beginning of a conversation, not the resolution of one. The brands winning procurement decisions right now are the ones who can go further than the report — with data, certifications, and packaging that holds up to scrutiny not just on paper but in the actual end-of-life scenarios buyers are now asking about.

Before You Walk Into That Buyer Conversation

The sustainability conversation has moved from intentions to evidence, and it's not moving back. Brands that can show verified lifecycle data, real end-of-life outcomes, and a clear EPR position in every market they sell into are winning procurement decisions that brands relying on directional language are losing. The report still matters. But the data behind it matters more, and the packaging it describes matters most of all. If your materials can't hold up to the questions buyers are now asking, the report won't cover for them.
