I warmly welcome you to the 4th International Conference on Green Sustainable Technology and Management (ICGSTM) 2025. On behalf of the organising committee, I extend warm greetings to all of you as we come together to deepen our commitment to sustainability and innovation.

Our conference is a global platform that brings together academics, researchers, and professionals from many fields. This year, we hope to build on the success of the previous three editions by encouraging collaboration and knowledge sharing in fields spanning from engineering and information technology to health, education, business, and management, all in line with the United Nations Sustainable Development Goals.

I warmly thank all of our presenters for their essential contributions, which will inspire conversations on critical problems of green technology and sustainability. I'd also want to thank our eminent keynote speakers for sharing their profound ideas and contributing to our collective understanding.

I'd want to take this opportunity to thank the ICGSTM 2025 organising committee, session chairs, and masters of ceremonies for their unwavering commitment. Your contributions are critical to the success of this conference, and I am certain that we will once again foster an environment conducive to research, collaboration, and the quest of a greener future.

Here's to a conference full of insightful talks and collaborative efforts.

Thank you for being a part of this transformational experience.

Associate Professor Dr. Douglas Law,

Conference Chair,
