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.”

Oxy CEO Vicki Hollub to retire, Reuters reports

retirement plans

Vicki Hollub, CEO of Houston-based Occidental (Oxy), is set to retire this year, Reuters first reported Thursday.

Hollub has held the top leadership position at Oxy since 2016 and has been with the oil and gas giant for more than 40 years. Before being named CEO, she served as chief operating officer and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Reuters reports that a firm date for her retirement has not been set. Richard Jackson, who currently serves as Oxy's COO, is expected to replace Hollub in the CEO role.

Oxy is leading a number of energy transition projects.

It's subsidiary 1PointFive is developing a $1.3 billion direct air capture (DAC) project in the Midland-Odessa area that is slated to be the largest facility of its kind in the world. Known as STRATOS, it's designed to capture up to 500,000 metric tons of CO2 per year.

The company shared recently that Phase 1 of the project is expected to go online in Q2, with Phase 2 ramping up through the remainder of 2026.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos last year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” she added.

Oxy was one of the first to set ambitious net-zero goals. In a 2020 interview during CERAWeek, Hollub outlined Oxy's future as a “carbon management company.”

“Ultimately, I don’t know how many years from now, Occidental becomes a carbon management company, and our oil and gas would be a support business unit for the management of that carbon. We would be not only using [CO2] in oil reservoirs [but] capturing it for sequestration as well,” Hollub said.

Oxy opened its Oxy Innovation Center in the Ion last year, focused on advancing low-carbon technology. It also operates Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others.

Hertha Metals named world's  No. 1 most innovative manufacturing co. of 2026

top innovators

Led by Conroe-based Hertha Metals, five organizations in the Houston area earned shoutouts on Fast Company’s list of the World’s Most Innovative Companies of 2026.

Hertha Metals ranked No. 1 in the manufacturing category.

Last year, Hertha unveiled a single-step process for steelmaking that it says is cheaper, more energy-efficient and just as scalable as traditional steel manufacturing. It started testing the process in 2024 at a one-metric-ton-per-day pilot plant.

At the same time, Hertha announced more than $17 million in venture capital funding from investors such as Breakthrough Energy, Clean Energy Ventures, Khosla Ventures, and Pear VC.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Laureen Meroueh, founder and CEO of Hertha, said at the time.

Meroueh was also recently named to Inc. Magazine's 2026 Female Founders 500 list.

Hertha, founded in 2022, says traditional steelmaking relies on an outdated, coal-based multistep process that is costly, and contributes up to 9 percent of industrial energy use and 10 percent of global carbon emissions.

By contrast, Hertha’s method converts low-grade iron ore into molten steel or high-purity iron in one step. The company says its process is 30 percent more energy-efficient than traditional steelmaking and costs less than producing steel in China.

Last year, Hertha said it planned to break ground in 2026 on a plant capable of producing more than 9,000 metric tons of steel per year. In its next phase, the company plans to operate at 500,000 metric tons of steel production per year.

Here are Fast Company’s rankings for the four other Houston-area organizations:

  • Houston-based Vaulted Deep, No. 3 in catchall “other” category.
  • XGS Energy, No. 7 in the energy category. XGS’ proprietary solid-state geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock is located. While Fast Company lists Houston as XGS’ headquarters, and the company has a major presence in the city, XGS is based in Palo Alto, California.
  • Houston-based residential real estate brokerage Epique Realty, No. 10 in the business services category. Epique, which bills itself as the industry’s first AI brokerage, provides a free AI toolkit for real estate agents to enhance marketing, streamline content creation, and improve engagement with clients and prospects.
  • Texas A&M University’s Nanostructured Materials Lab in College Station. The lab studies nano-structured materials to make materials lighter for the aerospace industry, improve energy storage, and enable the creation of “smart” textiles.
