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:

  1. San Diego, California
  2. Washington, D.C.
  3. Honolulu, Hawaii
  4. San Francisco, California
  5. San Jose, California
  6. Seattle, Washington
  7. Oakland, California
  8. Portland, Oregon
  9. Fremont, California
  10. 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.

Report: Here's how Houston ranks among the country's greenest cities

Seeing green

Houston may be the energy capital of the world, but it apparently isn't the capital of "greenness."

The Bayou City lands at No. 93 among the 100 largest U.S. cities in a new WalletHub ranking of the country's greenest places. Houston held the same spot in last year's ranking. Aside from being the eighth worst city in the 2021 study, Houston is the lowest-ranked city in Texas.

To determine the cities promoting an environmentally friendly lifestyle, WalletHub compared the 100 largest cities across 28 key "green" indicators. Those factors include greenhouse gas emissions per capita, number of smart energy policies and initiatives, and green job opportunities.

Unfortunately, Houston's overall showing isn't impressive. Here is a sampling, with No. 1 being best, No. 50 being average, and No. 100 being worst:

  • Excess fuel consumption per year, No. 97.
  • Greenhouse gas emissions per capita, No. 94. Houston tied with five other cities for the worst greenhouse gas emissions.
  • Median air quality index, No. 72.
  • Share of commuters who drive, No. 54.
  • Percentage of green space, No. 37.
  • Farmers markets per capita, No. 35.
  • Walkability, No. 34.

Here is how other Texas cities fared:

  • Austin, No. 26.
  • Garland, No. 44.
  • San Antonio, No. 46
  • Laredo, No. 68.
  • El Paso, No. 69.
  • Irving, No. 74.
  • Plano, No. 79.
  • Lubbock, No. 83.
  • Arlington, No. 85.
  • Dallas, No. 89.
  • Corpus Christi, No. 90.

San Diego tops the WalletHub list.As Houston hangs out toward the bottom of the WalletHub ranking, government and business leaders in the region are striving to make Houston greener.

For instance, the City of Houston in August launched a pilot project that will speed up the permitting process for environmentally friendly stormwater projects.

And just this month, Houston Mayor Sylvester Turner declared October 6 as Energy Efficiency Day. The occasion encouraged residents and businesses to support the city's clean energy goals. "Implementing energy efficiency measures is the cheapest, fastest, and cleanest way to reduce Houston's energy demand," the mayor's office says.

In a news release, Laura Patiño, the city's interim chief resilience officer, says Houston must come up with solutions to combat climate change, ensure a "just and equitable" transition to clean energy, and "promote economic growth in an inclusive and transparent manner."

Despite the poor performance in the WalletHub study, Houston continues to make headway in green energy.

For example, Turner in August touted Houston's status as the No. 1 municipal entity in the U.S. for the most annual consumption of power from renewable sources. The U.S. Environmental Protection Agency (EPA) list features participants in its Green Energy Partnership.

In a news release, Turner said the EPA recognition is "great news for the city of Houston and, by extension, for the rest of the world. We are going big to set the example for cities around the world. If 100 percent renewable energy can happen in Houston, it can happen in any other city."

Axis Research & Technologies, a California-based healthcare innovation solutions and medical research company, has expanded into the Houston area via a new 10,800-square-foot bioskills lab in Shenandoah last month.

The facility includes a main lab that’s configurable into a single space with over 20 stations, two more lab suites for specialized bioskills training, a conference room for presentations and a large multipurpose area.

Medical professionals can simulate a fully functional operating room in the lab for training and education. It also has the capability of handling cadaver specimens.

The company says the new facility aims to serve surgeons, medical device companies, hospitals and research institutions.

Axis was attracted to Houston thanks to the Texas Medical Center and other world-class medical groups, according to a release from the company. The facility in Shenandoah will be near medical facilities in The Woodlands.

“We are thrilled to expand into the Houston market,” Jill Goodwin, COO of Axis, said in a news release. “This new facility was driven by demand from our clients who have expressed a need for a high-quality bioskills lab in Houston. We repeatedly heard this feedback at the most recent American Academy of Orthopaedic Surgeons (AAOS) conference, which reinforced our decision to bring Axis to the region.”

Axis hosted its first lab event at its Houston-area venue on Feb. 22. The facility is currently accepting bookings for medical trainings, research collaborations and use of its bioskills lab.

“Our goal is to create an environment where groundbreaking medical advancements can take place,” Goodwin added in a news release. “Houston is home to one of the largest medical communities in the country, making it a perfect fit for our expansion.”

Axis' other bioskills labs are located in Nasvhille; Irvine, California; and Columbia, Maryland.

Texas institute grants $12M to bring leading cancer researchers to Houston

cha-ching

Rice University has recruited a prominent Swedish cancer researcher thanks to a $6 million grant from the Cancer Prevention and Research Institute of Texas.

It’s among $68 million in research grants recently awarded by the state agency, and six recruitment grants totaling $16 million to bring leading cancer researchers to Texas.

A news release from the Cancer Prevention and Research Institute of Texas (CPRIT) describes Pernilla Wittung-Stafshede of the Chalmers University of Technology in Gothenburg, Sweden, as “an accomplished and highly gifted biophysical scientist tackling complicated biological questions regarding the role of metals and metal dysregulation in various diseases. She pioneered a new research field around the role of metal ions in the folding and function of metalloproteins.”

Metalloproteins account for nearly half of all proteins in biology, according to the National Institutes of Health. They “catalyze some of the most difficult and yet important functions in [nature], such as photosynthesis and water oxidation,” the federal agency says.

Wittung-Stafshede, a professor of chemical biology and life sciences at Chalmers, is a former professor at Rice.

Aside from the money for Wittung-Stafshede, Houston recruitment grants also went to:

  • University of Texas M.D. Anderson Cancer Center: $2 million to recruit Rosalie Griffin of the Mayo Clinic
  • Baylor College of Medicine: $2 million to recruit Dr. Nipun Verma of the Yale University School of Medicine
  • Baylor College of Medicine: $2 million to recruit Xin “Daniel” Gao of Harvard University and the Massachusetts Institute of Technology

In Houston, cancer research grants were given to:

  • Baylor College of Medicine: $7.8 million
  • M.D. Anderson Cancer Center: $20.7 million
  • Rice University: $ 1 million
  • University of Houston: $1.2 million
  • University of Texas Health Science Center at Houston: $4.5 million

“The awards … represent the depth and diversity of CPRIT funding for cancer research in Texas,” says Kristen Doyle, CEO of CPRIT. “These grants develop new approaches to preventing, diagnosing, treating, and surviving cancer for all Texans.”
