Challenge your assumptions: how LCA reveals the true impact of packaging
By Barbara Nebel, thinkstep-anz. Demand for more sustainable packaging is rising across the food sector. Consumers want to buy ‘greener’ choices. Retailers are tightening expectations. Regulators are increasing scrutiny. For food brands, the focus is on avoiding costly packaging changes, protecting market access and making claims that can stand up to scrutiny. Decisions on packaging changes are not taken lightly. But what is perceived as environmentally friendly is not always the option that reduces impact. Paper can feel like the safer choice. Compostable packaging can sound like the lower-impact option. Plastic is often assumed to perform poorly from an environmental perspective. In reality, packaging impacts are rarely that simple. Packaging impact is easy to misread Packaging choices affect more than waste. They can influence transport emissions and food waste too. Looking at recyclability or compostability alone can miss the biggest impacts. For example: Heavier packaging can increase transport emissions across Australia’s long supply chains. Compostable packaging may not deliver benefits if there is no collection or processing infrastructure to support it. Packaging that reduces shelf life can increase food waste, which can outweigh the impact of the packaging itself. For food brands, this matters. Packaging is not just a wrapper. It is part of the whole product system. How Life Cycle Assessment helps With retailers, regulators and consumers scrutinising environmental claims, assumptions aren’t just risky – they threaten market access. This is why evidence, rather than intuition, is essential. This is where Life Cycle Assessment (LCA) comes in. It is a tool that measures environmental impact across a product’s full life cycle – from raw materials and manufacturing to use and disposal. It considers inputs like energy, materials and transport, and outputs like emissions, waste and pollution. LCA answers the crucial question: Which packaging choice reduces environmental impact when the […]
