Abstract

Carbon dioxide removal (CDR) involves capturing CO2 from the atmosphere and storing it for decades to millennia. Alongside deep emissions reductions, CDR is required for meeting the temperature goal of the Paris Agreement (IPCC 2022). However, parties to the agreement do not currently distinguish CDR from emissions reductions in their climate pledges. In this perspective, we argue that this lowers transparency and hinders the assessment of how credible and ambitious mitigation plans are.
