REYKJAVIK, ICELAND - MAY 24: Plant manager Terence Tham walks past the Climeworks' Mammoth carbon removal plant on May 24, 2024 in Reykjavik, Iceland. Considered the largest direct-air capture plant in the world, Swiss start-up Climeworks and Icelandic partner Carbfix have collaborated on the Mammoth project, utilizing Climeworks' Direct Air Capture (DAC) technology to extract CO2 directly from the air using fans and special filters. Powered by clean geothermal energy, the CO2 is then pumped deep into Iceland's bedrock, locking it away permanently. Mammoth's annual capture of 36,000 tons of CO2 is seen as a significant step in fighting climate change. (Photo by John Moore/Getty Images)
