The establishment of stringent climate goals resulted in the development of various technologies contributing to climate change mitigation. While most of them were developed, at least partially, for other purposes, carbon dioxide removal (CDR) and carbon dioxide capture, utilization and storage (CCUS) are the only technologies developed solely for the purpose of mitigation. Direct air capture (DAC) contributes to climate-change mitigation through CDR and the supply of low-emission fuels. Integrated assessment models (IAMs) have incorporated the latest mitigation technologies, supporting technology development and deployment as well as climate policy formulation. Most scenario studies targeting DAC have applied IAMs with partial equilibrium models at their core. This study developed a computable general equilibrium (CGE) model capable of analyzing mitigation scenarios considering DAC-related technologies.
