Sustainable transportation systems are undergoing a significant transformation driven by technological innovations, climate considerations, and changing policy frameworks. The International Sustainable Transportation Symposium (ISTRAS'25) examines the multi-disciplinary and cross-sectoral dimensions of sustainable mobility, focusing on areas such as aviation, smart urban transit, green logistics, renewable energy integration, and digital infrastructure. The symposium brings together cutting-edge research and practical approaches across land, air, and sea transport, with a strong emphasis on energy efficiency, emissions reduction, intelligent systems, and policy development. Topics covered include decarbonization pathways for aviation, smart transport networks, hydrogen and electric mobility, sustainable airport and seaport management, and integrated multimodal solutions. Contributions are organized into thematic sessions to ensure comprehensive coverage of technical, operational, and regulatory aspects and present original studies, case analyses, or concept-driven reviews.

Development Prospects for Sustainable Transport: Proceedings of the International Sustainable Transportation Symposium 2025 offers valuable expert-authored papers and keynote presentations that provide insights and guidance for researchers, practitioners, and policymakers striving to shape the future of sustainable mobility, particularly in the realms of aviation and transport innovation.
