The ruling was brought after a challenge to a lower court opinion brought by Texas and more than a dozen other states.
Vaibhav Bahadur, an associate professor in the Cockrell School of Engineering at the University of Texas at Austin called the SCOTUS decision significant, noting that Texas is the biggest energy producer in the U.S., and produces more energy than the United Kingdom.
“Power generation accounts for a significant fraction of U.S. carbon emissions, and the EPA loses its ability to control what's happening in about half of that sector,” Bahadur said. “And it's not just the U.S., I think people and environmentalists on pretty much anywhere on the planet will be disappointed because this is going in the wrong direction. We know we want to be decarbonizing, and this is essentially putting a roadblock on progress toward decarbonization.”
So, we’re going to need some insurance, Bahadur says. He’s carrying out work that’ll act as such through his research on carbon capture and sequestration (CCS), the process of sucking carbon from the air and burying it.
For the past five years, he’s been working on a novel approach to storing carbon. It involves supercharging the formation of carbon dioxide-based crystal structures and storing billions of tons of carbon under the ocean floor.
“If all of this is successful, then we will have another option for safely and responsibly storing carbon at the bottom of the seabed for essentially eternity,” Bahadur said.
Still, Bahadur talked about a different approach to responsibly cutting down emissions in the next decade, and doing so in a meaningful and substantial way, then the environment will eventually heal itself and we might not need CCS.
But that’s not the path we’re headed down.
“We're already starting to see temperature records being shattered this year, and we're still to hit peak summer,” Bahadur said. “All of this just makes me think that we need CCS to a larger extent, and possibly sooner than what a lot of scientists anticipate, especially if we can't keep our emissions in check.”
Gary Rochelle, a professor in the department of chemical engineering at UT, thinks CCS was ready to be deployed in 2010 and those 12 years have made a difference.
“But now we've emitted all that CO2,” Rochelle said. “And unfortunately, unlike other pollutants, when you emit CO2, it's there. It's not going away.”

Still, the delay is good in that now researchers like him have had time to learn about and improve the technology, allowing for fewer problems once it's deployed.
In December, UT announced a licensing agreement with advanced technology company Honeywell. The technology from that is targeted at power, steel, cement and other industrial plants to lower emissions.
Rochelle has been working on the technology since 2000 as part of an international collaborative effort. When he talked to Austonia on Thursday, he had just had calls with collaborators in Germany and Norway. Currently, he’s working with some Ph.D. students on addressing a chemical reaction that can happen with the technology known as oxidation that could lead to ammonia emissions and cause problems for a large-scale commercial unit.
Rochelle says he’s driven to this work because he wants to make a contribution.
“We're trying to develop this technology so that we can make a difference,” Rochelle said. “It's a nice problem to work on. The students are motivated and those are the primary things which drive us.”
Meanwhile, Texas Gov. Greg Abbott celebrated the high court’s decision which acted as a blow to President Joe Biden’s plan to reduce emissions.
“Today’s landmark victory against an out-of-control administration is also a big win for Americans who worry about skyrocketing energy costs due to expensive federal regulations that threaten our energy industry,” Abbott said. “President Biden cannot keep attacking the energy industry and the hardworking men and women who power our nation.”
