Sustainable aviation is a long-term strategy to provide innovative solutions to the industry's environmental challenges. The International Symposium on Sustainable Aviation is a multi-disciplinary symposium that presents research on current sustainability-based issues and future trends in aviation from an economic, social, and environmental perspective. The conference provides a platform offering insights on a broad range of current issues in aviation, such as aviation and environment, commercial air transport, regulations and policy, sustainable aerospace vehicles and technologies, and environmental modeling and measurements. The ISSA symposium allows researchers, scientists, engineers, practitioners, policymakers, and students to exchange information, present new technologies and developments, and discuss future direction, strategies, and priorities in sustainable aviation topics.
