A technology that once existed only in science fiction soon could emerge as a viable solution to climate change. The city of Flagstaff has added carbon dioxide removal to its plan to reach carbon neutrality by 2030.
Flagstaff officials say once the technology is proved and deployed, it will extract and neutralize carbon and other pollutants from the atmosphere.
In recent years, significant progress has been made in developing systems that can remove greenhouse gases from the atmosphere.
Ramon Alatorre is climate and energy coordinator for the northern Arizona city. He said it could be one of the first in the country to implement a climate plan to capture and store carbon dioxide.
"We can do as much reducing as possible, but we're still going to be producing some emissions," said Alatorre. "And so there's going to, by necessity, be the other half of the equation. In order to be net zero, we're going to have to remove emissions from the atmosphere."
Alatorre said demonstration projects in Iceland and around the world show promise, but are not yet ready for commercial deployment.
He said his office also is working closely with the Center for Negative Carbon Emissions at Arizona State University to develop CDR technology.
Alatorre said Flagstaff is part of the Four Corners Coalition with other governments across the region - including Boulder County, Colorado - seeking to obtain the new technology when it becomes available.
"If we join with Boulder and half a dozen other communities," said Alatorre. "And suddenly we've got an aggregated demand and an aggregated pool of resources that really might attract somebody that wouldn't have looked at Flagstaff by ourselves."
Alatorre said while communities such as Flagstaff eventually will utilize a variety of solutions for removing greenhouse gases, he believes CDR will play a major role in cleaning the atmosphere.
He said while the technology may be expensive, the cost of not dealing with climate change could be much higher.
"Cost curve reduction could be achieved certainly by mid-century if we get started now," said Alatorre. "But that we need those early projects to get the ball rolling, that it's really going to be deployment-led innovation that result in cost coming down and scalability coming up."

Nine in 10 people in Virginia and across the globe are worried about climate change and want governments to do something about it, according to a new survey but they mistakenly assume others do not share their view.
Anthony Leiserowitz, director of the Yale Program on Climate Change Communication, called it a perception gap.
"The average person believes that other people in their own country tend not to worry about climate change that much," Leiserowitz reported. "When, in fact, the majority of people in most countries do worry about climate change."
The gap in perception has real-world policy implications. In the U.S., almost 80% of congressional staffers underestimated their constituents' support for reducing climate pollution, sometimes by more than 50 percentage points.
Leiserowitz stressed helping more people understand they are not in the minority could unlock a social tipping point, moving leaders to act.
He pointed to one example where 96% of liberal Democrats and 78% of conservative Republicans supported helping farmers protect and restore soil to absorb more carbon dioxide. He acknowledged progress is stymied by misperceptions.
"If your perception is that Republicans are absolutely against climate policy, then many people might then conclude -- especially if you're a policymaker -- that we shouldn't be taking action," Leiserowitz outlined. "When, in fact, there's overwhelming support, even among conservative Republicans."
Decades of misinformation campaigns, aiming to protect fossil-fuel company profits, play a big role in perception gaps. Leiserowitz added gaps also persist because any two individuals, not knowing what the other thinks, are likely to avoid topics they believe are controversial, including climate change.
"That leads neither of us to talk about it," Leiserowitz observed. "Well, now expand that to 300 million people, and you can see that we start slipping down this 'spiral of silence.' Nobody talks about it, so nobody talks about it. Which means nobody talks about it."

New Mexico's decades-long drought combined with climate change have more farmers and ranchers embracing the six healthy soil principles, tailoring how each parcel of land is managed.
New Mexico's farming practices date back at least 2,500 years but the state's Healthy Soil Working Group said the arid climate and diverse ecology make a one-size-fits-all approach ineffective.
Dave Dubois, climatologist at New Mexico State University, said the recent storm should improve this year's snowpack but farmers and ranchers must plan five or 10 years into the future.
"The scenarios from climate change models are showing warmer temperatures, hotter droughts and then more evaporation," Dubois explained. "How do you manage all that in a system where we still have agriculture as our cultural identity?"
Agriculture is the state's third-largest industry after energy and aerospace. The majority of New Mexico's farmland is heavily dedicated to growing grass, which feeds livestock, provides sod and serves as a cover crop to protect soil health between harvests.
Many factors contribute to soil degradation: intensive farming practices, deforestation, overgrazing, urbanization and erosion.
Ernest Diswood, a Navajo conservation leader, said using regenerative techniques, he has been improving his range soil since 2009.
"We're seeing, despite the drought now, about 21 species of grasses and we're probably between 700 to 1,000 pounds an acre," Diswood outlined. "For the Navajo Indian Reservation, that's usually a pretty good number."
Keeping soil covered is one of the six healthy soil principles.
Ralph Vigil, owner of Molino de la Isla Organics and an eighth-generation acequia farmer, changed his practices nearly 20 years ago. A lack of moisture led him to reduce the East Pecos land where he grows organic vegetables from five acres, to a half-acre. To improve the soil, he now uses drip irrigation and other conservation techniques.
"The acequia sees less water; I've done more cover-cropping to try to help build my soil, keeping my cover present at all seasons because (of) no snowpack, lack of rain and wind," Vigil emphasized. "Wind is beating us up and it doesn't go away. So, just trying to keep that soil covered at all times."
Significant cuts made by the Trump administration to the Natural Resources Conservation Service are expected to reduce climate-friendly programs nationwide.
