Climeworks AG is a Swiss company headquartered in Zurich, founded in 2009, specializing in direct air capture (DAC) technology for carbon dioxide removal.
The company develops, builds, and operates modular DAC plants that filter CO₂ directly from ambient air using renewable energy-powered adsorption-desorption processes. Captured CO₂ is either permanently stored underground, such as through mineralization in Iceland via partnerships like Carbfix, or supplied for uses including carbon-neutral fuels and materials.
Key facilities include Orca (4,000 tons CO₂/year) and Mammoth (36,000 tons/year), the world's largest operational DAC plant, both in Iceland. Climeworks provides high-quality carbon removal services to companies seeking net-zero goals and has raised over $1 billion in funding to scale toward gigaton capacity.
