<p>Greenhouse gas (GHG) emissions pose a significant threat to climate change, with projections estimating emissions to range between 48 and 55&#xa0;Gt per year by 2050. CO₂ is the dominant contributor to GHG emissions, accounting for over 80% of the total emissions. Carbon Capture, Utilization, and Storage (CCUS) has emerged as a crucial strategy for reducing these emissions, with solid adsorbents offering a promising alternative for post-combustion CO₂ capture. This study provides a comprehensive review of recent advancements in sustainable solid adsorbents, including zeolites, mesoporous silica, carbonaceous materials, and metal–organic frameworks (MOFs). The performance of these materials has been critically analyzed in terms of adsorption capacity, selectivity, stability, and regeneration efficiency. A key challenge in the commercialization of CO₂ adsorption technologies is the high energy demand for regeneration. This review further evaluates emerging regeneration techniques, such as microwave, ultrasound, magnetic, and electrochemical methods, which offer the potential for more energy-efficient and rapid desorption processes. By systematically comparing adsorbent properties and regeneration strategies, this study identifies research gaps and highlights pathways for the development of cost-effective and sustainable CO₂ capture technologies. These findings contribute to the advancement of solid-adsorbent-based CCUS solutions, supporting global efforts toward achieving carbon neutrality.</p> Graphical Abstract <p></p>
