Show moreLooking for a global and corrective measure to reduce greenhouse gas emissions from international civil aviation has been facing legal obstacles. These obstacles took the form of conflicts of norms linked to the general challenge of the interactions between international aviation law, climate change law and the law of the European Union. Using evolutionary interpretation of the Chicago Convention in order to reconcile norms of substantive and institutional nature emerged as the best solution. However, this method perpetuates legal uncertainty and poses the general challenge of flexibly and elasticity of the Chicago Convention in response to the climate change challenge. This study examines the above mentioned issues of interactions between legal orders and provides recommendations to restore legal certainty needed to ensure sustainable development of international civil aviation. More specifically, this study reveals the underestimated relevance of the ongoing distinction between the legal regimes of air navigation and international air transport, which is a key legal element in the search for a global and corrective solution to the impact of international civil aviation on climate change.
