5 facts about scrubbing carbon from the air

Direct air capture systems use chemical filters or liquid solvents to pull carbon dioxide from ambient air.

Removing carbon from air is energy intensive because it exists in such low concentrations.

Captured carbon can be stored permanently underground or converted into products like concrete and fuel.

The Mammoth project in Iceland is a milestone facility capable of capturing 36,000 tonnes of carbon annually.

Capturing half a million tonnes of carbon via direct air capture requires significantly less land than reforestation.
