Direct Air Carbon Capture
Technologies that pull carbon dioxide directly out of ambient air will be required if humanity is to get its CO2 emissions down to zero. Direct air capture will be a useful last resort to offset CO2 emissions that are impossible, impractical or too expensive to eliminate or capture at their source.

Methane has a greenhouse effect 80 times worse than carbon dioxide over a 20-year period, and emissions are skyrocketing even as we start reducing CO2. That makes UCF's new hydrocarbon-capturing, sunlight-powered catalyst a very compelling idea. -
Captura Corporation has developed a revolutionary plan to remove carbon emissions by creating an aquatic purification facility in the middle of the sea. The company intends to extract carbon dioxide from ocean water using only renewable electricity. -
An ambitious startup called Climeworks is looking to eat into the world's carbon emissions and has just taken its biggest bite yet, flicking the switch on the largest direct air capture and CO2 storage plant on the planet.
