Box TS.10 | Carbon Dioxide Removal (CDR) Carbon Dioxide Removal (CDR) is necessary to achieve net zero CO; and GHG emissions both globally and nationally, counterbalancing “hard-to-abate’ residual emissions. CDR is also an essential element of scenarios that limit warming to 1.5°C or below 2°C (>67%) by 2100, regardless of whether global emissions reach near zero, net zero or net negative levels. While national mitigation portfolios aiming at net zero emissions or lower will need to include some level of CDR, the choice of methods and the scale and timing of their deployment will depend on the achievement of gross emission reductions, and managing multiple sustainability and feasibility constraints, including political preferences and social acceptability CDR refers to anthropogenic activities removing CO, from the atmosphere and durably storing it in geological, terrestrial, or ocean reservoirs, or in products....
