This special issue on Carbon Capture, Utilization, and Storage (CCUS) addresses the critical role of CCUS in mitigating climate change by bridging energy needs and environmental goals. It explores various aspects of CCUS, including enhanced oil recovery (EOR) technologies, geological storage mechanisms, and CO₂ utilization methods. The articles delve into factors influencing CO₂-EOR efficiency, innovative materials for profile control in high-temperature applications, and the potential of mineralization-driven storage in sandstones and shales. Additionally, the issue examines safety concerns related to wellbore integrity and proposes solutions for long-term infrastructure durability. Contributions also highlight the development of CO₂-mineralized materials from industrial waste, showcasing the integration of decarbonization and waste management. This collection of research aims to foster meaningful discussions and guide future investigations in the field of CCUS.

In the ever-evolving landscape of geospatial technology, innovations are steadily advancing our capabilities in Earth monitoring and urban planning. Precise positioning technologies and geoinformation science have become essential for various applications, from scientific research on global climate change and earthquake monitoring to supporting major initiatives in satellite navigation and smart city development. This article explores recent advancements in the field, including improvements in Terrestrial Reference Frame accuracy, real-time seismic monitoring through Global Navigation Satellite Systems (GNSSs), the development of advanced hyperspectral imaging systems, new techniques for ionospheric irregularity detection, and the creation of three-dimensional (3D) building space datasets for urban planning. These developments, while incremental, collectively enhance our ability to understand and manage our planet's resources and urban environments with greater precision and insight.
