Conference on Carbon Dioxide Removal

Removal of non CO2 gases This category focuses on approaches to remove greenhouse gases other than carbon dioxide, such as methane and nitrous oxide. Discussions may explore emerging technologies, natural processes, and monitoring approaches aimed at reducing atmospheric concentrations of these gases. Contributions examining their potential climate benefits, feasibility, and integration with broader mitigation strategies are encouraged. CDR scenarios and temperature overshoot This category focuses on the role of CDR within climate scenarios that aim to achieve net-zero or net-negative emissions. Discussions may address the feasibility and scale of different CDR pathways, the role of CDR in addressing temperature overshoot, and the interaction between removals and residual emissions. Contributions may draw on scenario modelling, integrated assessment models, or other approaches to explore implications for climate targets and near-term decision-making. Pathways for CDR uptake This category explores mechanisms and enabling conditions that support the deployment and adoption of CDR approaches. Topics may include innovation systems, financing models, policy instruments beyond carbon markets, and opportunities for scaling across sectors. Discussions may also address potential co-benefits, additionalities, and interactions with other technologies and sustainability objectives. Justice, ethics, and social perceptions of CDR This category addresses the ethical, social, and governance dimensions of carbon dioxide removal. Topics may include distributive and procedural justice, public participation, societal acceptance, and the ethical implications of deploying CDR at scale. Contributions may also explore public attitudes, stakeholder perspectives, and the broader societal considerations that shape responsible research, development, and governance of CDR. Policy, economics and upscaling This category explores the policy frameworks, economic instruments, and governance mechanisms needed to support the development and large-scale deployment of CDR. Topics include regulatory approaches, incentive structures, public and private investment, market mechanisms, and cost assessments. Contributions may analyse policies at international, national, regional, or sub-national levels and examine how they influence innovation, adoption, and responsible scaling of CDR technologies and practices. Fundamental Science and Technology This category focuses on advances in the fundamental scientific and technological understanding underpinning carbon dioxide removal (CDR). Discussions may address the physical, chemical, and biological processes that enable carbon removal and storage, as well as laboratory and early-stage technological developments. Contributions exploring mechanisms, experimental results, modelling, and innovations that improve the effectiveness, efficiency, or durability of CDR approaches are welcome. Climate system effects of net-negative emissions This category examines how net-negative emissions influence the climate system. Discussions may explore climate feedbacks, atmospheric responses, and the potential reversibility or irreversibility of climate impacts following carbon removal. Contributions may also address the implications of temporary or impermanent removals and the broader physical climate consequences of large-scale deployment of CDR. CDR interactions: mitigation & adaptation pathways This category examines how CDR interacts with wider climate mitigation and adaptation strategies. Contributions may analyse synergies and trade-offs between carbon removal and sectoral decarbonisation, residual emissions, land use, and adaptation planning. Discussions may consider how CDR can be integrated into comprehensive climate strategies while managing potential risks and unintended consequences. Measurement, Reporting and Verification This category addresses innovations in measurement, reporting, and verification (MRV) systems for carbon dioxide removal. Discussions may include new methodologies, monitoring technologies, and data integration approaches that improve transparency, accuracy, and credibility in CDR accounting. Particular attention is given to the integration of emerging tools such as artificial intelligence and Earth observation with conventional monitoring methods at project, organisational, or national levels. Lifecycle & techno-economic assessment/integration This category focuses on evaluating the performance and feasibility of CDR approaches across their lifecycle and supply chains. Topics include lifecycle assessment (LCA), techno-economic analysis (TEA), and the integration of CDR within broader energy, industrial, and land systems. Contributions may examine system-level impacts, resource requirements, and the role of CDR in integrated climate mitigation pathways using modelling or other analytical frameworks.
