How does Climeworks' direct air capture technology work?
Why do we need direct air capture?
Why don't we just plant trees?
Why not capture CO₂ from point sources, e.g. directly from a smokestack, where the CO₂ concentration is much higher?
How much energy is required to run Climeworks' direct air capture process?
Do Climeworks' direct air capture machines operate better at higher levels of CO₂ in the air?
Is the air really free from carbon dioxide when it leaves the Climeworks CO₂ collector?
What can the CO₂ produced by direct air capture be used for?
Your machines capture carbon dioxide. But how much carbon dioxide is caused by the production, commissioning and recycling of your machines?
How many direct air capture machines have you sold?
Is it safe to remove carbon dioxide from the atmosphere and turn it into stone?
How does Climeworks remove the CO₂ I have subscribed for and how long does it take?
What is the difference between Climeworks' carbon dioxide removal service and traditional carbon offsetting?
Do I get some sort of certificate?
How can I edit or cancel my subscription?
