PhD Project
Alongside deep emission reductions, carbon dioxide removal (CDR) is increasingly recognized as a necessary component of Germany’s climate commitment to reach net-zero emissions by 2045. However, large-scale CDR deployment is typically assessed in terms of cost-effectiveness and large-scale technological feasibility, while questions of local feasibilities, sustainability and environmental justice remain underexplored.
This dissertation project investigates how place-specific dynamics and interdependencies between sub-national social, ecological and technological systems (SETS) influence the just and sustainable deployment of CDR in Germany. Using a multi-methods research design across three interrelated studies, the project examines both nature-based and novel CDR approaches.
Study 1 develops a spatial multicriteria analysis to identify regional synergies and trade-offs for nature-based CDR options by integrating environmental conditions, land-use constraints and policy priorities. Study 2 builds on these findings by conducting an in-depth case study, combining qualitative stakeholder input with agent-based modeling to explore decision-making logics and institutional barriers. Study 3 shifts the focus to novel CDR options, particularly BECCS and DACCS. Drawing on expert interviews, it examines the local environmental, social, and justice challenges associated with building CO2 transport and storage infrastructure in Germany.
By integrating social, environmental, and technological dimensions of CDR through the SETS perspective, the project contributes to academic and policy debates on CDR governance and supports the development of context-sensitive, just, and sustainable climate policy in Germany.
