Charting the technical landscape of marine carbon dioxide removal Dr Nils Thonemann and Mona Delval from the University of Leiden consider the scientific and technical requirements for effective evaluation of emerging marine carbon dioxide removal (mCDR) approaches. As the world strives to meet ambitious net-zero targets, the ocean is emerging as a potential key territory in the fight against climate change. Marine environments already absorb over a quarter of anthropogenic CO2 emissions each year (1); thus, scientists and innovators are currently exploring ways to actively enhance this natural sink through so-called marine carbon dioxide removal (mCDR) approaches.

Thonemann et al. (Fri,) studied this question.
