Abstract: Carbon Capture and Storage (CCS) project, as an emerging emission reduction technology to solve the global warming climate problem, needs to explore its promotion mechanism from a multidimensional microscopic perspective. The perceptions and responses of human to information that refers to global carbon emissions, carbon emission reductions and climate change (hereinafter referred to as carbon emotions), will also affect the low-carbon behaviors of government, enterprises and citizens by influencing their perception of the riskiness of carbon emissions. In this paper, the influence of carbon emotions of participants is introduced to the game analysis framework, and Rank-Dependent Expected Utility (RDEU) theory and game theory are combined to explore the micro-mechanism of carbon emotions affecting the development of CCS projects. First, based on the development status of CCS projects, a RDEU-game model between government and energy enterprises is constructed. Second, five heterogeneous emotion combinations are proposed, including “government and energy enterprises are both rational”, “government and energy enterprises are both pessimistic”, “government and energy enterprises are both optimistic”, “government is pessimistic and energy enterprises are optimistic”, “government is optimistic and energy enterprises are pessimistic”. Under the above five heterogeneous emotion combinations, the equilibrium strategy choicesof government and energy enterprises are analyzed.Finally, taking Guohua Shenmu Oxygen-Enriched Combustion Reform Project as an example, the above game equilibrium results are simulated and the following important conclusions are drawn.When the two participants are both rational, their willingness to participate in CCS projects is very low, which is consistent with the current development status of international CCS projects.The more pessimistic the two participants are, the more likely the government take no action and the energy sectors choose CCS technology transformation, which is a manifestation of the optimization of social resource allocation.When the two participants are both optimistic, moderate optimism is conducive to stimulating the benign development of CCS projects, and excessive optimism will hinder the development of CCS projects. Therefore, countermeasures are proposed to manage social carbon emotions from the perspective of carbon emotion guidance, in order to accelerate the scale and commercial operation of CCS projects.
