What is sustainable packaging? A practical definition for brands
Sustainable packaging is more than a label — it's a measurable balance of materials, end-of-life and supply chain. Here's how to define it for your brand.
'Sustainable packaging' is one of the most overused phrases in consumer goods. To make it useful for procurement, design and marketing, brands need a working definition with measurable criteria — not a marketing slogan.
The four pillars
1) Material: recycled, renewable or bio-based input with verifiable certification (FSC, PCR %, TÜV OK Compost).
2) End-of-life: a realistic disposal pathway your customers can actually access — curbside recycling, industrial composting or in-store drop-off.
3) Carbon: lower cradle-to-gate CO₂e than the incumbent pack, ideally validated by an LCA.
4) Supply chain: produced in mills running on renewable energy and shipped close to your fulfilment hub.
What it is not
'Bio-based' alone is not sustainable — sugar-cane PE still ends up as plastic litter without a collection system.
Single attributes (FSC paper with a PE laminate, for example) often cancel out under LCA scrutiny.
How to apply it
Score each SKU against the four pillars on a 0–3 scale. Anything scoring 8+ out of 12 can credibly carry a 'sustainable' claim with on-pack proof points.
Re-score annually — supplier mix, recyclate availability and certifications all shift.
