Carbon Dioxide Removal (CDR) to reach net-zero and return from overshoot: knowledge gaps and research priorities

About

This session addresses carbon dioxide removal (CDR), which was found to be unavoidable to reach net-zero CO2 or GHG emissions in AR6 WG III & SYR, and which is an essential element of returning from a temporary temperature overshoot, via net-negative CO2 emissions.


Since COP21 in Paris, there has been a clear trend to increasingly integrate CDR in climate policymaking (considerations), which may accelerate with the emerging discussion on overshoot trajectories for 1.5C. This can, for example, be detected in AR6 products, but also annual reports like the UNEP Emissions Gap Report 2023. It can be expected that CDR will play a bigger role during the Seventh Assessment Cycle than in AR6.


After an initial presentation on the AR6 approach, speakers IPCC AR6 authors will provide insights on emerging research areas and persisting knowledge gaps, including on Earth System responses, CDR and natural ecosystems, CDR innovation and policymaking, overlaps/delineations between CDR, CCS and CCU, and CDR in global mitigation scenarios.
