<p>Alongside substantial and rapid emissions reductions, Carbon Dioxide Removal (CDR) is necessary to keep global warming to well below the 2&deg;C temperature goal set by the Paris Agreement. The Intergovernmental Panel on Climate Change (IPCC) and the global community have emphasised the importance of CDR to reduce atmospheric CO2 and manage potential overshoot scenarios. While the attention has so far predominantly focused on land-based CDR methods, marine CDR (mCDR) approaches have increasingly moved into the spotlight. What significant challenges does the implementation of mCDR methods face? How can dedicated political solutions help address the challenges associated with mCDR? What are the strengths and limitations of the most prominent mCDR approaches?</p>
