Swiss company Climeworks has developed a system to remove carbon dioxide from the air and keep it from being re-released into the atmosphere.
Their technology uses a process called direct air capture, which processes air through filters that can capture and trap carbon dioxide. The air exits the system with 90 percent less carbon than air entering the system. At a geothermal plant in Iceland, Climeworks technology has been used to create the world’s first negative emission power plant, which removes more CO2 from the air than it produces.
While captured carbon can be used to create carbon-neutral fuel, plastic and a range of other materials, the Iceland plant has found a way to inject it underground and transform it into stone, preventing the carbon from being re-released into the atmosphere for millions of years.
So far, direct air capture is only a small part of the global effort to mitigate climate change. It is currently prohibitively expensive and small in scale, but is developing quickly and attracting funding from power investors like Bill Gates.
For the world to meet the goals laid out in the Paris Agreement, we’ll very likely need to not only reduce carbon emissions but also remove emissions from the air. Direct air capture plants like Climeworks and others aim to do so while providing jobs and powering a “new, clean economy.”

Solar Trumps Coal When It Comes to Jobs, Cash Handouts Deter Crime in California and More
Solar Now Provides Twice As Many Jobs As the Coal Industry, Co.Exist
While the coal industry faces a sharp decline, solar power is growing at record levels — adding jobs at a rate 17 times faster than the overall workforce. The industry is also a more lucrative option for people without higher education. As one advocate puts it, “This is just an incredible example of the opportunities that exist for people that need these opportunities the most.”
Building Trust Cuts Violence. Cash Also Helps. The New York Times
A radical approach to gun violence has helped reduce the homicide rate by nearly 60 percent in Richmond, Calif., formerly one of the nation’s most dangerous cities. Spearheaded by DeVone Boggan, a NationSwell Council member, the program identifies those most likely to be involved in violent crimes and pays them a stipend to turn their lives around. Aside from the cash benefits, participants receive mentoring from “neighborhood change agents” who have come out of lives of crime themselves.
Iceland Knows How to Stop Teen Substance Abuse but the Rest of the World Isn’t Listening, Mosaic Science
In the last two decades, Iceland has implemented an ambitious social program that’s nearly eliminated substance abuse among teens. After research showed that young people were becoming addicted to the changes in brain chemistry brought on by drugs and alcohol, experts decided to “orchestrate a social movement around natural highs,” offering extensive after-school programs in sports, dance, music — anything that could replicate the rush of drugs. This, coupled with stricter laws and closer ties between parents and schools, led to a huge societal makeover. Proponents of the program hope to recreate it in the U.S., but funding and public opinion remain obstacles.
