2024 // ASMASYS Report

Unified ASsessment framework for proposed methods of MArine CDR and interim knowledge SYnthesiS (ASMASYS)

In ASMASYS, one of the main goals is to establish a comprehensive assessment framework for marine carbon dioxide removal (mCDR) and marine carbon storage (mCS) options, serving as a foundational tool for evaluating various methods uniformly. This is essential for several reasons: As the marine environment offers enormous potential for mCDR and mCS initiatives to remove and store significant amounts of CO2 from the atmosphere, these methods also come with unique challenges and risks, particularly in terms of environmental impact and regulatory compliance. By creating a comprehensive assessment framework, policy makers, scientists and stakeholders can evaluate and assess the feasibility, effectiveness, environmental and ethical implications of marine mCDR/mCS methods.

9 Propositions on the Ethics of Marine-based Carbon Dioxide Removal (mCDR)

Should we intervene in marine biological and geochemical processes in order to protect the climate? An answer to this question must be informed by natural science and economic research. However, we also must face questions of justice and morality, questions about our norms and values and how marine-based carbon dioxide removal (mCDR) relates to them. This poster presents nine propositions on the ethics of using the ocean to intentionally remove CO2 from the atmosphere.
