The carbon dioxide capture, utilization and geological storage (CCUS) is one of the key technologies to reduce emissions of greenhouse gases (GHGs) in fighting against global climate change. With rapid economic development in China, the energy conservation and the GHG emission reduction are important, especially for the sustainable development of green gross domestic producst. In September 2011, "Technology Roadmap Study on Carbon Capture, Utilization and Storage in China" was issued by the Department of S&T for Social Development, Ministry of Science and Technology of the People's Republic of China and the Administrative Center for China's Agenda 21. This first CCUS roadmap sets some milestone objectives in 2015, 2020 and 2030, as well as some suggestions for priority technical development of fundamental researches and applied technology researches for the demonstration objectives. The first milestone (2015) has just reached. This paper reviews the latest literature and expert panel discussions, and it is shown that China has built a number of CCUS pilot and demonstration projects, and the priority deployment has also made some progress, but on the whole the current progress lags behind the target by about 2-3 years. In this context, this paper suggests that, to achieve the milestone object of 2020, it is necessary to solve the financing problem of large scale integrated projects to improve the economic efficiency of CCUS technology, and at the same time, and to solve the scale-up problems of all key technologies of CCUS technology. Finally, it is shown that when setting new targets for a coming China's CCUS roadmap (updated edition), in addition to considering the development level of mainstream technologies and emerging technologies, the impact of national policies on choices and applications of the technologies for CCUS projects should be considered.
