In recent years, carbon capture, utilization and storage (CCUS), as one of the key technologies to address climate change, has attracted extensive attention from the international community. The Working Group III contribution to the IPCC Sixth Assessment Report (AR6) has repositioned CCUS, and assessed carbon capture and storage (CCS), carbon capture and utilization (CCU), bioenergy with carbon capture and storage (BECCS), direct air carbon capture and storage (DACCS) systematically and comprehensively, with focusing on mitigation potential and cost, comprehensive benefits and application prospects. The results show that CCUS is an indispensable combination of emission reduction technologies for the realization of global climate targets, which has the potential to achieve cumulative hundred-billion tons reduction effects by the middle of the 21st century. However, the current maturity of CCUS technology is overall at the demonstration stage and the cost is high, with mitigation potential to be further released. Considering CCUS can effectively reduce the risk of huge amount of stranded assets and has good social and environmental benefits, it’s necessary for China to regard CCUS as a strategic technology under the context of its own resource endowment. To promote the development of CCUS, China should coordinate top design, accelerate the construction of technology system, explore market incentive mechanism, and strengthen international cooperation.

Key words: Carbon capture, utilization and storage (CCUS), Technology assessment, Mitigation potential, Integrative benefit
