Air scrubbing machine in Iceland

In this September 2021 image provided by Climeworks AG, CEOs Jan Wurzbacher and Christoph Gebald appear in front of an air-scrubbing machine where fans suck air into big, black collection boxes where the carbon dioxide accumulates on a filter at Climeworks’ Orca plant near Reykjavik, Iceland. The Iceland plant is the largest such facility in the world, capturing about 4,000 metric tons of carbon dioxide per year. (Climeworks AG via AP)
