Most carbon capture technologies create more emissions than they save  | Tallbloke’s Talkshop

Most carbon capture and utilisation (CCU) technologies, which pull carbon dioxide from the air and use it for other emissions-lowering processes, emit more carbon than they capture, reports New Scientist.

Kiane de Kleijne at Radboud University in the Netherlands and her colleagues assessed the life cycles of more than 40 CCU processes against three criteria: could they permanently store CO2; does the CO2 they collect come from atmospheric and natural sources; and does the process have zero emissions.

Kleijne and her team found that the majority of these technologies failed to meet these criteria, with 32 of the 40 emitting more carbon than they captured.
