It is with great honor and enthusiasm that I welcome you to the Fourth International Conference on Sustainable Mobility Applications, Renewables and Technology (SMART 2025), hosted by the College of Engineering at King Faisal University (KFU) in the historic and forward-looking city of Al-Ahsa, Kingdom of Saudi Arabia.

This conference stands as a beacon of collaboration at a time when the world demands bold ideas and transformative solutions. From sustainable transportation systems to clean energy innovations and smart urban environments, SMART 2025 brings together global pioneers from academia, industry, and government to shape the technologies and policies that will define our collective future.

Under the guiding vision of Saudi Arabia’s Vision 2030, the College of Engineering at KFU is proud to lead this international forum that not only showcases cutting-edge research, but also cultivates the partnerships needed to translate innovation into impact. The themes explored here reflect the urgency of our time reducing carbon footprints, advancing energy efficient systems, and building resilient, smart infrastructures.

Beyond the technical sessions, SMART 2025 offers a unique opportunity to connect with peers, explore new perspectives, and engage in meaningful dialogue that transcends disciplines and geographies. We invite you to fully immerse yourself in this experience — to learn, to contribute, and to collaborate.

As General Chairman, I extend my deepest appreciation to our keynote speakers, authors, reviewers, sponsors, and organizing committees who have dedicated their time and expertise to making this event a success. I also thank each of you — the participants — for your commitment to innovation and sustainability.

Together, let us make SMART 2025 not only a platform for knowledge exchange, but a catalyst for action and enduring progress.

Welcome to Al-Ahsa. Welcome to SMART 2025.

Warm regards,
