Towards harmonised life cycle assessment in aviation: Barriers, enablers, and a roadmap for sector-wide inventory data

Kurzfassung

Life Cycle Assessment (LCA) is key to evaluating aviation’s environmental impacts, but fragmented Life Cycle Inventory (LCI) data limits the consistency and comparability of results. This research proposes an initial roadmap for a common, aviation-specific LCI database, structured around governance, policy drivers, data requirements, and the role of LCA practitioners in stakeholder engagement. It identifies critical gaps and offers a blueprint for more transparent, comparable assessments across the sector.
