Carbon dioxide removal (CDR) will be needed, alongside deep emissions cuts, to achieve global temperature goals. o C or 2 o c, in line with the Paris Agreement, global carbon dioxide emissions must reach net-zero between 2050 and the early 2070s. Scientists have proposed a number of land- and ocean-based CDR techniques.
