This paper explores the implementation of Life Cycle Assessment (LCA) as a strategic framework for improving waste management practices in airports, with a particular focus on the Baltic region. By synthesising global research on LCA applications in aviation, it identifies both promising approaches and unresolved challenges. Findings indicate a growing international trend toward using LCA for waste reduction, emissions tracking, and material reuse in airports. However, methodological inconsistencies such as unclear system boundaries and a lack of regional data limit the comparability of studies. Notably, the Baltic region remains underrepresented in current LCA research. This paper advocates for region-specific studies to align airport waste strategies with EU sustainability directives and to support evidence-based environmental planning in the Baltic States.
