Trivium Packaging’s 2021 Global Buying Green Report found that consumers have a measurable and growing preference for sustainable packaging when choosing food and beverage products. But consumer preference doesn’t automatically become retail practice, and for most retailers, packaging is the highest-volume, highest-visibility sustainability decision they make every year.
Here’s how to approach it with specificity rather than aspiration.
The Packaging Audit Comes First
Before selecting materials, you need a baseline. Which packaging formats generate the most waste volume? Outer shipping cartons? Polybags? Tissue paper? Protective fill? The answer varies significantly by category, and the environmental return from improvement varies with it.
A simple audit (one week of cataloguing what leaves your facility by weight and material type) is usually enough to identify the two or three categories where changes will have the most impact. Target those first rather than trying to improve everything at once.
Two certification frameworks that matter here: the Forest Stewardship Council (FSC) for paper and cardboard verifies responsible sourcing. The How2Recycle label from the Sustainable Packaging Coalition provides standardized consumer guidance on how to dispose of each packaging component. Both are widely recognized by environmentally engaged consumers and appear on credible sustainability marketing.
Material Choices With Real Impact
Switching from virgin to recycled polyethylene terephthalate (rPET) in retail packaging can reduce carbon emissions by up to 79%. Adding recycled HDPE can cut packaging emissions by up to 71%. These are material science outcomes, not marketing claims.
For e-commerce specifically, right-sizing packaging is the highest-leverage change. Oversized boxes with excessive fill material increase shipping weight, volume, and cost simultaneously. A design investment in packaging that fits the product (with purpose-built inserts rather than generic filler) typically pays back within two to three shipping cycles.
The BioPak and FSC certifications are worth seeking out in packaging suppliers before committing to volume. They verify that your materials meet minimum environmental standards, which matters both for internal accountability and for external communication credibility.
Reusable packaging (where the container is returned, cleaned, and refilled rather than discarded) is the most environmentally excellent option and the most operationally complex. Companies like Lush, Rituals, and Elate Cosmetics have built refill programs, but these require customer behavior change and reverse logistics infrastructure. Start here only if you have the operational capacity to support it consistently.
The most powerful packaging improvement available to most retailers costs nothing: use less of it. Right-sizing boxes, eliminating unnecessary inner packaging, and reducing dunnage weight produce environmental and cost improvements simultaneously.
Waste Reduction Beyond Packaging
Packaging is the most visible category, but retail waste reduction extends further.
Composting unsold food (for food retailers and restaurants) is a mandatory starting point, not just for environmental reasons, but for the methane calculation. Food in landfill generates methane at 25 times the global warming potential of CO2. Diverting it to composting eliminates that problem while creating a marketable soil amendment.
Employee education on waste reduction is more effective when it’s specific rather than motivational. Clear instructions on what goes in which bin, regular waste audits that show staff where the waste is actually coming from, and visible tracking of progress toward targets all outperform general “please reduce waste” communication.
Donating unsold product to food banks or community organizations reduces waste while creating a deductible charitable contribution and a community relationship. The organizational friction of building that donation pipeline is real but one-time; once the relationship is established, the diversion becomes routine.
P.S. Before ordering any new sustainable packaging, request samples and test how your customers actually dispose of them in your market: “recyclable” packaging that ends up in landfill because your customers don’t have curbside recycling access isn’t achieving its purpose.
