Understanding the true environmental impact of packaging requires looking beyond materials and design.
Lifecycle assessment (LCA) and carbon footprinting have emerged as essential tools for evaluating packaging sustainability, enabling businesses to quantify emissions, identify hotspots, and make informed decisions about reducing their environmental footprint.

With growing consumer and regulatory pressure to cut carbon emissions, interest in packaging LCA and carbon footprint analysis has never been higher.
The importance of lifecycle assessment in packaging
A packaging lifecycle assessment analyses a product’s entire journey—from raw material extraction and manufacturing to distribution, use, and disposal. By measuring impacts across each stage, LCAs offer a holistic perspective that single-point assessments cannot match.
For packaging manufacturers and brands, conducting an LCA reveals which stages contribute most to greenhouse gas emissions, resource depletion, or waste generation.
For example, a lightweight plastic pouch may seem environmentally preferable to a heavier glass jar, but an LCA might show the pouch relies on fossil-based materials and energy-intensive processes, leading to a higher carbon footprint overall.

LCA results can also guide packaging design choices, encouraging the selection of materials with lower embodied energy or easier recyclability.
Reusable and refillable packaging systems often show significant emissions reductions over single-use options when analysed over multiple cycles, reinforcing their value in circular economy strategies.
Measuring and reducing carbon footprint of packaging
Carbon footprinting is a focused measure of greenhouse gas emissions associated with packaging, typically expressed as kilograms of CO₂ equivalent (CO₂e) per unit produced.
It provides a straightforward metric for comparing the climate impacts of different packaging options and tracking emissions reductions over time.
Calculating a packaging carbon footprint involves assessing energy use in manufacturing, transportation emissions, and end-of-life treatment. Businesses increasingly rely on international standards such as ISO 14067 and the Greenhouse Gas Protocol to ensure accurate and consistent carbon accounting.
Reducing packaging’s carbon footprint often starts with material choice. Shifting from virgin to recycled content can cut emissions substantially; for instance, using recycled aluminium requires up to 95% less energy than producing new aluminium from bauxite.
Similarly, innovations in lightweighting reduce material use without compromising performance, lowering both resource consumption and transport-related emissions.
Optimising packaging design to improve pallet efficiency or reduce void space can also shrink the carbon footprint by enabling more goods to ship per lorry or container, thus decreasing emissions per product delivered.
At end of life, designing for recyclability or compostability diverts packaging from landfill and reduces methane emissions, further lowering the overall carbon impact.
Challenges and future trends in packaging sustainability assessments
While lifecycle assessment and carbon footprinting provide invaluable insights, they can be complex and resource-intensive processes.
Gathering accurate data across global supply chains remains a significant challenge, especially for small and medium-sized enterprises lacking in-house expertise or budget for comprehensive studies.
Data gaps can introduce uncertainty into results, which may limit the confidence of stakeholders relying on the findings.
However, advancements in digital tools are helping to simplify and democratise packaging LCA and carbon accounting.
Cloud-based software platforms now allow brands to input material and production data to quickly estimate carbon footprints, offering a more accessible entry point for businesses seeking to measure and improve their environmental performance.
Another emerging trend is the inclusion of broader environmental and social metrics into packaging assessments. While carbon emissions are a critical factor, issues such as water use, biodiversity loss, and social impacts of sourcing materials are increasingly considered in holistic sustainability strategies.
This multi-dimensional view supports the growing consumer expectation for truly sustainable packaging that respects both people and the planet.
Looking ahead, as extended producer responsibility (EPR) regulations spread globally, more companies will need to document the environmental impact of their packaging.
EPR schemes often include eco-modulated fees—charging lower rates for easily recyclable or low-carbon packaging—which directly incentivises sustainable design choices.
