State of the Ocean Report

The new UNESCO-IOC State of the Ocean Report is out. Miranda Böttcher, member of CDRmare / ASMASYS co-authored the section on mCDR. This chapter gives an overview over proposals to increase the ocean’s carbon drawdown capacity using so-called ‚marine carbon dioxide removal‘ (mCDR) techniques. The recent surge of interest in mCDR techniques poses many technical, environmental, political, legal and regulatory challenges. These techniques are all still at early stages of development with much still to be learned about them and their effects before any decisions could be made about large-scale deployment.
