Global Conference for Decarbonization of Energy and Materials (GC-DEM2024). For millennia, humans are able to generate, accumulate, distill, and employ knowledge creatively so as to secure their own survival, comfort, and well-being on planet Earth.  Moving forward it is necessary for them to decarbonize energy and materials so as to ensure the well-being of ecosystems of Earth on which they invariably depend.  Means of decarbonisation of energy and materials are multi-faceted.  GC-DEM is a multi-disciplinary international conference on all aspects of decarbonisation.  This global conference aims to provide a high-quality platform for the exchange of scientific knowledge and technological innovations, dissemination of relevant research studies and findings, showcasing of scaled-up solutions, and advocating future-shaping priorities, policies, standards, and regulations.  All stakeholders are encouraged to participate in this knowledge-sharing event and contribute to shaping the desired shared future of humanity.
