Climate & Environment at Imperial Blog: What to do with all the carbon dioxide?
"It has long been assumed that carbon capture and storage (CCS) will cover an important portion of the emissions that need to be reduced to avoid the risk of dangerous levels of climate change. But the technology has yet to be deployed on a scale large enough to do that.

This is where negative emissions technologies (NETs), which rely in large part on CCS (see box on NETs), come in."
