Bad news, Houston. The Bayou City is the third worst metro when it comes to the country's greenest cities.

According to WalletHub's recently released Greenest Cities in America report, Houston is No. 98 out of 100 of the largest cities that were ranked in the study, which was based on information from the U.S. Census Bureau, U.S. Environmental Protection Agency, The Trust for Public Land, U.S. Department of Energy - The Alternative Fuels Data Center, and more.

“There are plenty of things that individuals can do to adopt a green lifestyle, from recycling to sharing rides to installing solar panels on their homes. However, living in one of the greenest cities can make it even easier to care for the environment, due to sustainable laws and policies, access to locally-grown produce and infrastructure that allows residents to use vehicles less often," says Chip Lupo, WalletHub Analyst. "The greenest cities also are better for your health due to superior air and water quality.”

Houston scored 36.88 points out of 100, and comes in dead last on the environment ranking. Here's how the city performs when it comes to the other metrics:

No. 87 for transportation
No. 52 for energy sources
No. 61 for lifestyle and policy
No. 91 for greenhouse-gas emissions per capita
No. 30 for percent of green space
No. 86 for median air quality index
No. 97 for annual excess fuel consumption
No. 56 for percent of commuters who drive
No. 39 for walk score
No. 33 for farmers markets per capita

The big winners on the report are mostly on the West Coast. Of the top 10, six cities are from California. These are the greenest cities, per the report:

San Diego, California
Washington, D.C.
Honolulu, Hawaii
San Francisco, California
San Jose, California
Seattle, Washington
Oakland, California
Portland, Oregon
Fremont, California
Irvine, California

Texas isn't seen on the list until Austin, which ranked No. 26. The rest of the major Lone Star State major metros include San Antonio at No. 44, Fort Worth at No. 76, and Dallas at No. 81.While this report is pretty damning, there's not a general consensus that all hope is lost for Houston when it comes to being green. Last year, the city was ranked as having the lowest carbon footprint, based on a report from Park Sleep Fly.

However, WalletHub's report has pretty consistently ranked Houston low on the list. Last year, Houston was slightly higher up at No. 95. In 2022 and 2021, the city claimed the No. 93 spot.

Artist collective brings carbon-absorbing murals to Houston

WHEN FINE ART MEETS FRESH AIR

Anthony Rose, the CEO of creative agency United By Design, is on a mission to brighten Houston’s urban spaces and improve the city’s air quality one carbon-absorbing mural at a time.

Rose originally founded United By Design, or UXD, in 2019 to connect muralists like himself and commercial businesses seeking to beautify their spaces and form brand identities. After creating vibrant murals for Lockhart Elementary School, the Houston Astros, and Smoothie King, Rose expanded UXD’s vision to include environmental sustainability in their artistic collaborations in 2022.

“This city’s vibrant art scene and growing focus on sustainability makes it an ideal location for our projects,” Rose says. “We’re not just creating eco-friendly murals, we’re reimagining how art can actively contribute to environmental solutions.”

In search of ecologically-conscious paints, Rose formed a partnership with Spain-based, natural paint company Graphenstone. Rose says he was drawn to the company’s eponymous Graphenstone coating because of its nontoxic ingredients and exclusively uses the product for UXD’s carbon-absorbing murals.

The Graphenstone coating consists of a limestone base which goes through a process called photocatalysis, during which carbon dioxide from the atmosphere is absorbed into the surface, and is then sealed in with graphene, a thin layer of carbon atoms. The murals absorb carbon dioxide throughout the coat’s drying process which typically takes 30 days.

“Each of our murals absorbs about 1600 grams of CO2 during that curing process which is the equivalent daily absorption of about 33 growing trees,” Rose explains.

UXD’s largest carbon-absorbing mural to date is a floor-to-ceiling panorama in downtown Houston’s historic Mellie Esperson building, home to the company’s new creative hub. Painted by Houston-born artist Emily Ding, the mural is a tribute to the establishment’s namesake: an innovative, early 20th century entrepreneur who constructed the opulent building.

Rose says UXD plans to expand their carbon-absorbing murals project in collaboration with more local artists and establishments, while creating an artist-in-residency program themed around sustainability. Though Rose acknowledges in the grand scheme of carbon pollution these murals are not a silver bullet, he says the non-toxic paints are encouraging conversations about how artists can be conservation-minded.

“We’re trying to figure out how art as a messaging tool can help break down scientific data, a language not many people practice daily, can break down barriers and help bridge the gap to a more intuitive knowledge of sustainability,” Rose says. “We’re bringing the community together, helping them feel empowered, and giving them actionable information to help them live more sustainable lives.”

KBR announces name, brand for government services spinoff

new identity

Houston-based KBR Inc.'s new Mission Technology Solutions unit officially has a name.

The previously announced government services spinoff, which until now has been nicknamed SpinCo, will now be known as Trinzic. The company said in a news release that the name was inspired by the word intrinsic, "reflecting essential, built-in capabilities and deep expertise operating in some of the world’s most complex and mission-critical environments."

New York-based firm Siegel + Gale developed the company's new brand. In addition to the new name, the company shares that its new logo will feature a stylized letter N, with brand colors in orange and gray.

“Trinzic represents who KBR Mission Tech has always been at our core: an essential partner bringing innovation and trusted execution to the missions that matter most,” Stuart Bradie, KBR President and CEO, said in the release. “The new Trinzic brand represents both our strong heritage and the tremendous opportunity ahead. Our teams aim to deliver solutions that address some of the world’s most critical national priorities every day, and this new identity captures the purpose-driven culture and mission focus that we expect to continue to define the company moving forward.”

KBR expects the spin-off to be completed in January 2027. At that time, Trinzic will operate as an independent, publicly traded company that will focus on technology and engineering services for the space and national security sectors.

KBR will remain a separate publicly traded company that will focus on sustainable technology and services to support the energy transition. KBR first announced the spinoff plans in October 2025.

Last month, KBR announced two C-suite hires for Trinzic, or what was then known as SpinCo.

Michael LaRouche will serve as Trinzic's inaugural president and CEO. LaRouche is currently CEO of Serco North America, a Virginia-based government services contractor. Nicholas Veasey, current CFO of Virginia-based MAG Aerospace, was named Trinzic's CFO. Bradie will remain chairman, president and CEO of KBR.

Rice lands $19M NSF grant to build AI-driven quantum materials lab

Quantum Boost

Rice University has received a $19.9 million award from the National Science Foundation to increase the production of quantum and electronic materials by using a combination of artificial intelligence, cloud-based labs and robotics.

The four-year project will create a remote and automated research platform that aims to accelerate discovery and the testing process, according to Rice. The aptly titled project, "Revolutionizing AI-Driven Autonomous Experimentation for Next-Generation Semiconductor Synthesis” (READINESS), will be led by Rice materials scientist Jun Lou, who serves as principal investigator. SUNY Polytechnic Institute and the University of Texas at Austin will collaborate with Rice on the project.

At first, READINESS will focus on two-dimensional materials, oxide semiconductors and diamond thin films that can support emerging technologies, like quantum devices.

READINESS is one of 20 projects selected for the NSF's Programmable Cloud Laboratories Test Bed initiative, which aims to provide more U.S. researchers with access to automated scientific tools.

Additionally, the project aligns with the Department of Energy’s Genesis Mission, which recently selected four projects from Houston universities and companies, including two from Rice. The national initiative aims to unite government, industry, academia and philanthropy to lead to breakthroughs in energy, scientific discovery and national security.

READINESS will offer more advanced lab systems remotely via a cloud interface to assist startups, other research groups, and companies that don’t have the resources, staffing or equipment to produce quantum materials and advanced electronics. READINESS will also allow researchers to simulate experiments via virtual experiments or digital twins before they conduct the physical experiment.

Rice says this will be particularly useful in quantum materials research, which is often met with barriers— like the adjustments of chemical composition, gas flow, pressure, and temperature—that can change the properties of a material.

“This project will give researchers access to capabilities that have traditionally been available only in a handful of laboratories,” David Sholl, executive vice president for research at Rice, said in a news release. “By lowering those barriers, READINESS can accelerate discovery and expand who can participate in cutting-edge materials research.”

Additionally, the project’s AI aspect will offer recommendations for new tests, recognize safety limits and analyze results to assist researchers.

“Responsible AI should complement researchers’ capabilities rather than replace their judgment,” Luay Nakhleh, Dean of Rice’s George R. Brown School of Engineering and Computing, added in the release. “READINESS embodies this principle by combining automated systems with transparency, safeguards and human oversight at critical decision points.”

READINESS’ lab will be based out of Rice’s Ralph S. O’Connor Building for Engineering and Science. Partner sites will also contribute equipment, expertise and workforce development programs, according to Rice.

Ultimately, READINESS aims to elevate the speed, reliability and reproducibility of experiments, and to promote access to automated scientific tools for U.S. researchers.

“Our goal is to create a laboratory that researchers from across the country can use to produce advanced electronic and quantum materials on demand,” Lou added in the release. “By integrating robotics, AI and digital twins, we aim to learn from every experiment and shorten the pathway from scientific discovery to practical technology.”
