The world’s biggest carbon-sucking machine is switching on in Iceland

Operated by the Swiss engineering startup Climeworks, the plant, known as Orca, will annually draw down a volume of emissions equivalent to about 870 cars. Orca will boost total global DAC capacity by about 50%, adding to the dozen or so smaller plants that are already operational in Europe, Canada, and the US. The plant is composed of eight boxes about the size of shipping containers, each fitted with a dozen fans that pull in air.
