Unit Load Devices (ULD) play a critical role in global air cargo operations, supporting safety, efficiency, and standardized handling across the supply chain. As sustainability expectations grow across the aviation sector, interest in comparing the environmental performance of products and equipment such as like ULDs has also increased. Yet existing approaches often fall short.
New IATA Guidance for ULD Life Cycle Assessment
To address these gaps and support consistent evaluation practices, IATA has developed dedicated guidance for conducting Life Cycle Assessments (LCA) for ULDs. This guidance is an adaptation of the IATA Life Cycle Assessment Methodology for Single-Use Plastic Products in the Airline Sector (2025), a comprehensive ISO-aligned framework. While the single-use plastics methodology remains the core reference, the ULD-specific guidance highlights additional considerations essential to the category, including durability, repair and refurbishment, pooling and repositioning dynamics, and end-of-life pathways.
The guidance has been reviewed by the IATA ULD Board (ULDB) to ensure technical robustness and industry relevance, and it has now been formally incorporated into the IATA Unit Load Device Regulations (ULDR) as Appendix J, making it directly accessible for operational and procurement decision-making. Readers are encouraged to use the single-use plastics methodology as the baseline and apply the ULD-specific guidance to ensure these factors are consistently captured.
Harmonization Offers A Path Forward
As of today, many life cycle assessments rely heavily on tare weight as a proxy for environmental performance. While mass does influence fuel burn, it captures only a fraction of a ULD’s true environmental footprint. A ULD’s impact extends far beyond its weight: manufacturing processes, material extraction, repair cycles, repositioning movements, and end‑of‑life treatment all contribute significantly to its overall sustainability profile. This means a more holistic methodology is essential: one that can assess all stages of a ULD’s life rather than focusing on a single attribute.
In addition, aviation stakeholders operate under diverse regional rules and expectations for environmental reporting and product end‑of‑life management. This fragmentation can make it difficult for airlines, ULD manufacturers, and service providers to align on consistent performance measures.
The harmonized, ISO‑aligned IATA LCA methodology offers a path forward. It ensures that environmental assessments consider all materially relevant impact categories, enabling more meaningful comparisons and supporting sustainability improvements across the related to ULDs sector.
