Overview
Climeworks removes carbon dioxide from the atmosphere using modular direct air capture collectors. The captured CO2 can be permanently stored through mineralization or reused as a raw material in various industries. The company sells CO2 removal services and carbon credits to individuals and businesses, offering both subscriptions and one-time purchases, as well as partnerships to meet sustainability goals. Its approach centers on scalable, modular plants, including a large facility in Iceland, making it a leader in direct air capture since 2017. The goal is to help achieve net-zero emissions by providing a scalable solution to remove CO2 and support climate-positive outcomes.
