Abstract: Amid the accelerating global response to climate change, carbon capture, utilization, and storage （CCUS） technologies have attracted increasing international attention due to their indispensable role in carbon-neutrality strategies. In recent years, governments across multiple countries have actively advanced CCUS demonstration projects through diverse policy instruments, including legislation, fiscal incentives, and technology roadmaps, in order to expedite commercialization. Against this backdrop, this study systematically reviews global CCUS-related policies from 1970 to 2024 using the International Energy Agency （IEA） policy database, categorizing them into 13 policy tools according to functional attributes, target groups, and implementation pathways, and developing a four-dimensional framework comprising economic incentives, national strategies, legislative and regulatory measures, and social demand. Using the top ten countries by announced project numbers as the sample, we identify 178 policy texts and 319 project cases for integrated qualitative and quantitative analysis. The results reveal three concurrent trends in the global CCUS policy landscape: Temporal acceleration, diversification of policy types, and cross-country heterogeneity. Specifically, economic incentives are most prevalent in the United States （19%）, national strategies in the United Kingdom （16%）, legislative and regulatory measures in the United States （53%）, and social demand policies in Australia （15%）. Furthermore, a panel fixed-effects regression further indicates a significant positive correlation between policies and the number of project announcements, with the dynamic effect of economic incentives being the most pronounced—highlighting the critical role of fiscal and subsidy instruments in facilitating project implementation. Guided by China’s dual-carbon targets, policy design could draw on international experience by establishing diversified, CCUS-specific economic incentive mechanisms within the existing carbon market, while continuously strengthening regulatory frameworks and deepening international cooperation to achieve policy synergies and accelerate large-scale CCUS deployment.
