Carbon is the cornerstone of the industrial era of human society. The carbon dioxide (CO 2) produced by human beings using carbon-containing resources should not be a threat to human society or the terminator of carbon resource utilization, but a resource that could be made full use of to achieve sustainable development. Based on the rapid development of CO 2 utilization technology in China, this study proposes several CO 2 reduction schemes that may be suitable for China in the future, with large-scale CO 2 utilization as the core, including the CO 2 conversion and utilization technology coupled with fossil energy or zero-carbon energy, and the direct conversion and utilization technology of CO 2 under mild conditions. Fossil energy coupled with CO 2 conversion and utilization technology, which has experienced rapid growth in recent years due to the easy access and low cost of fossil energy, will bring huge carbon emission reduction potential and economic benefits in the near future. Meanwhile, nuclear/renewable energy assisted CO 2 to fuel and chemicals technology, boosted by the advancement of zero-carbon power generation technologies, promises to be one of the most competitive controllable CO 2 reduction technologies in the medium term. Solar-driven CO 2 conversion technology, which can realize the ecological carbon cycle, is expected to be the most promising CO 2 reduction technology in the long run.
