Paris goals demand rapid CDR scale-up

Deployment of new carbon dioxide removal technologies such as Beccs and Daccs must accelerate over the next decade, says University of Oxford report

New carbon dioxide removal (CDR) technologies such as bioenergy with CCS (Beccs) and direct air CCS (Daccs) must scale up “rapidly” over the next decade if the world is to reach the Paris Agreement goals, according to a new report led by the University of Oxford’s Smith School of Enterprise and the Environment. Virtually all scenarios that limit global warming to 1.5°C or 2°C require new, or “novel” CDR such as Beccs, biochar, Daccs and enhanced rock weathering, according to the report titled The state of carbon dioxide removal. Only a tiny fraction—0.002Gt/yr of CO₂—of current CDR is achieved via these methods, says the report, which was funded by organisations including financial instituti
