Compared to other forms of CDR, DACCS requires little land and carries fewer environmental risks. Still, scaling up DACCS technologies requires the support of a complex array of policies and infrastructure across multiple overlapping policy areas, such as climate, energy, technology innovation and natural resource management. DACCS policies will be built on the foundations of existing policies in these areas and will be influenced by the structure and content of this policy landscape. While the literature on DACCS and other CDR technologies acknowledges the path-dependent nature of policy development, it has tended to focus on abstract policy prescriptions that are not rooted in the specific political, social and physical (infrastructural) context of the implementing state. This thesis addresses this deficit by identifying the key policy foundations for developing and deploying DACCS at scale in Canada. Drawing on socio-technical transitions theory, particularly the multi-level perspective, I identify the constituent policy areas that are likely to form the future DACCS policy regime. The purpose of this policy review and analysis is to show that the policies used to deploy DACCS will need to address systemic issues of social acceptability; financing climate mitigation innovations; energy system and resource constraints; coordinating and regulating carbon storage and transport; and establishing general climate policies that support the role of DACCS in the transition process. Using a database of Canadian climate policies (n=457), I populate these key policy areas with existing policies, which enables me to map and analyze the emergent DACCS policy landscape in Canada. The growing body of literature on the policies needed for scaling up DACCS provides a basis for analyzing the adequacy of Canada’s current policies while creating system maps has allowed me to identify the potential trajectories of the system by identifying potential niches and broader landscape influences within the system, as well as identifying gaps and potential barriers to the system transition process. This thesis contributes to our understanding of national-level DAC policy development by providing a framework for identifying components of the DAC system and linking those components to desired policy outcomes.enclimate policynegative emissionsdirect air capturecarbon dioxide removalsystems analysisenvironmental governanceenergy transitionCanadian policycarbon capture and storageMaster Thesis
