By capturing straight air, carbon is taken out of the air. Climeworks opened the biggest carbon capture plant in Iceland this year, but it’s not the only way to cut down on pollution.
Changemakers in the Climate
These people and groups are ready to face the climate disaster head-on. In 2009, Christoph Gebald and Jan Wurzbacher were “young, motivated, and maybe a little naive” when they chose to start a business based on technology that could pull carbon dioxide out of the air.

Future ways to deal with climate change
The two Mechanical engineers met at ETH Zürich. They saw directly how climate change was affecting their favorite ski area in France, where the glacier was quickly melting, and they decided to do something about it. Climeworks is a company in Zurich, Switzerland, that forever stores carbon dioxide in the ground by pulling it out of the air.It’s easy to understand what direct air capture is all about.
This stuff is made up of chemicals called amines, which bind carbon dioxide when they combine with it. When a filter is full, it is heat to about 100°C. This breaks the weak chemical bonds between the amine and carbon dioxide, which lets the carbon dioxide be gather and turn into a liquid. Getting rid of carbon dioxide is only about half done. Next, make sure it stays safe and sound.
Climeworks has teamed up with Carbfix, an Icelandic company that came up with a way to mix carbon dioxide with water and pump it down into rocks, where it reacts with the water and turns the carbon dioxide into stone. Climeworks’ pieces are made up of separate parts, so the system can be made bigger or smaller. The amines that are us in the filters are easy to find and don’t cost much. Geology that stores things underground can be found all over the world, and it only releases about 10% of the CO2 that it collects over its entire life.

Increasing Direct Air Capture
Wurzbacher says that Climeworks would need about 750,000 of their units to soak up 1% of the world’s CO2 emissions in a year. He thought it was too much until he learned that every two weeks, which is one of the busiest ports in the world. “It’s possible,” he says. “It’s not insignificant, but it’s doable.” When done on that scale, direct air collection would almost likely cost less than $1,000 per tonne, maybe even $100 per tonne.
Fight CO2 Emissions Around the World
Frank Jotzo, director of the Australian National University’s Centre for Climate Economics and Policy in Canberra, Australia, and batteries for electric vehicles shows how costs go down as technologies get bigger. He thinks that direct air capture will follow the same path. When that happens, direct air capture and other technologies very important in stopping the last few hard-to-avoid emissions that can’t be stop any other way.
What we do know is that some operations that emit CO2 or other greenhouse gases will be so expensive to decarbonize that it will be cheaper to draw down atmospheric CO2 instead,” says Jotzo. Companies like Microsoft, Stripe, Shopify, and Audi are now using Climeworks to reduce their carbon footprints. At the same time, they are keeping an eye on that French glacier that is melting away. “We must mitigate,” Wurzbacher states, “but that will not be enough; we will have biological remedies, but they will not be enough.” “Because of this, technical solutions are need.”
The Future of Direct Air Capture Technology
Direct air capture (DAC) is rapidly emerging as one of the most promising technological solutions in the fight against climate change. While reducing emissions remains the top priority, from the atmosphere is equally critical to meet global climate targets. DAC systems, like those developed by Climeworks, use advanced chemical processes to capture CO₂ directly from ambient air and store it permanently underground, preventing it from re-entering the atmosphere.
As the technology scales, costs are expect to decline significantly—similar to what happen with solar energy and electric vehicles. Today, carbon removal costs can range widely, but innovations and large-scale deployment are already pushing prices downward, making DAC more commercially viable for industries and governments.
Moreover, DAC offers a unique advantage: does not require large land areas like forests or bioenergy systems. This flexibility makes it a powerful complement to renewable energy and other climate solutions. Although challenges such as high energy use and infrastructure development remain, direct air capture as a key pillar in achieving net-zero emissions by mid-century.
Conclusion
Direct air capture represents a groundbreaking, the technology is evolving quickly, with falling costs, increasing global investment, and growing corporate adoption. However, DAC is not a silver bullet; strategies such as clean energy transition and conservation efforts. If scaled effectively, direct air capture could play a crucial role in stabilizing global temperatures and securing a sustainable future for generations to come.
FAQs
Q: What is direct air capture?
Direct air capture is a technology that removes carbon dioxide, directly from the air using chemical filters and stores it underground or reuses it.
Q: Why is DAC important for climate change?
Because reducing emissions alone is not enough—DAC helps remove existing CO₂ already in the atmosphere.
Q: Is DAC technology expensive?
Yes, currently it is costly, ranging from about $100 to $2,000 per ton, but prices are expect to decrease as the technology scales.
Q: Can DAC completely stop climate change?
No, it is not a standalone solution. It must be us alongside renewable energy, emission reductions, and natural solutions.
Q: Where is DAC currently being us?
DAC plants are operating in countries like Iceland, the United States, and Canada, with more projects under development globally.
