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.

Houston e-waste recycling business advances sustainability mission with new accreditation

seeing green

An innovative Houston company focused on sustainable tech recycling has expanded.

CompuCycle describes its unique Plastics Recycling System as the first and only certified, single solution e-waste recycling business. The company's unique process can now break down discarded technology products into single polymers that can then be reused in the manufacturing process.

“Properly managing all components of electronics is a cornerstone of sustainability and environmental responsibility,” Kelly Adels Hess, CEO of CompuCycle, says in a news release. “Making single polymer plastics that original equipment manufacturers (OEMs) can reuse to produce new electronics or other products, while adhering to international recycling standards, is a gamechanger for domestic companies and those that need their plastics shipped globally.”

As of now, CompuCycle reports that it's the only service in the country that can provide a recycling solution for both metals and plastics in-house. The company has met the Environmental Protection Agency’s two accredited certification standards, e-Stewards and R2 certification requirements, per the release.

“We saw an opportunity to solve an industry challenge by creating the first domestic, sustainable, single-solution e-waste plastics program that reduces the amount of plastic negatively impacting the environment, while also making it advantageous for companies to recycle and reuse. It’s truly a win for everyone involved,” adds Clive Hess, president at CompuCycle.

CompuCycle, which has over a 20-year history, added recycling electronics to its toolkit in 2019. While CompuCycle has focused on responsible electronics disposal since Kelly's father-in-law, John Hess, founded the company in 1996, certain recent events have increased the need to recycle more efficiently.

"China is no longer accepting scrap, which is where a lot of materials would go after it was dismantled," Kelly told InnovationMap in 2019. "That's why we've created this solution to be able to responsibly handle it here in the U.S."

EPA settles with Houston recycling company over Clean Air Act violations

paying penalties

Officials have reached an agreement with a Houston-based company over alleged violations of the federal Clean Air Act.

Under a proposed settlement with the U.S. Justice Department and the federal Environmental Protection Agency, Derichebourg Recycling USA Inc. will prevent the release of ozone-depleting refrigerants and non-exempt substitutes from refrigerant-containing items at its 10 scrap metal recycling facilities in Texas and Oklahoma. Derichebourg also will pay a $442,500 penalty.

Derichebourg Recycling USA’s parent company is France-based Derichebourg SA, an operator of scrap metal recycling facilities.

A complaint filed in federal court alleges Derichebourg Recycling USA failed to recover refrigerant from appliances and motor vehicle air conditioners before disposal, and failed to verify with the supplier that refrigerant had been properly recovered before delivery.

The complaint focuses on alleged Clean Air Act violations at three Derichebourg scrap metal recycling facilities in Houston: 7501 Wallisville Rd., 8202 W. Montgomery Rd., and 1 Wharf St. Environmental Protection Agency (EPA) inspections in 2018 led to the complaint.

Derichebourg operates three other facilities in the Houston area: 3515 Almeda Genoa Rd. and 6648 N. Eldridge Pkwy., both in Houston, and 13319 FM 1764 in Santa Fe.

“To continue protecting stratospheric ozone, we need companies like Derichebourg to comply with the Clean Air Act when recycling appliances and motor vehicles containing harmful refrigerants,” Todd Kim, an assistant U.S. attorney general, says in a January 7 news release.

The refrigerant, R-12, is one of the most destructive ozone-depleting substances and has a global warming potential greater than 10,000 times the power of carbon dioxide, according to the news release.

“Refrigerants that are not captured properly can be damaging to the earth’s ozone layer and are known to increase greenhouse gasses, which leads to climate change,” says Larry Starfield, acting assistant administrator of the EPA.

The agreement, called a consent decree, still requires approval from a federal judge in Houston. The consent decree is signed by two EPA attorneys and the CEO of Derichebourg Recycling USA, Philippe Leonard.

Houston continues its reign as the top city using renewables, per the EPA

seeing green

The City of Houston continues to electrify the country when it comes to the use of green power.

The U.S. Environmental Protection Agency (EPA) ranks the city first among municipal entities for the highest annual consumption of power from renewable sources. The list features participants in the EPA's Green Energy Partnership.

The EPA pegs the City of Houston's annual use of green power at a little over 1 billion kilowatt-hours. That's enough electricity to power more than 94,000 average U.S. homes in a year's time. No other municipal entity uses more than 1 billion kilowatt-hours of green power per year.

The City of Houston has held the No. 1 spot on the municipal list since 2014. Among all users of green power in the U.S. that participate in the EPA's Green Energy Partnership, the city ranks 19th.

Since July 2020, all City of Houston facilities have been powered by 100 percent renewable energy derived from solar and wind sources. Houston-based NRG supplies the electricity for those facilities.

In an August 11 news release, Houston Mayor Sylvester Turner says 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."

The news release points out that green power helps offset damage from ozone, acid rain, haze, fine particles, and other harmful pollutants. Fine particles come primarily from exhaust produced by vehicles, as well as from the burning of coal, wood, and heating oil, and from forest fires and grass fires.

The City of Houston isn't the only municipal outfit in Texas that shines on the EPA list. Here's are four others among the top 30 municipal users of green power:

  • City of Dallas, ranked second, 701.8 million kilowatt-hours of green power used each year.
  • Dallas-Fort Worth International Airport, ranked fifth, 450.2 million kilowatt-hours of green power used each year.
  • City of Austin, ranked sixth, 325.3 million kilowatt-hours of green power used each year.
  • City of Irving, ranked 30th, 24.9 million kilowatt-hours of green power used each year.

Nationally, these five Texas businesses rank among the top corporate users of green power:

  • Dallas-based AT&T, ranked seventh, 2.36 billion kilowatt-hours of green power used each year.
  • Irving-based Kimberly-Clark, ranked 18th, 1.03 billion kilowatt-hours of green power used each year.
  • Round Rock-based Dell, ranked 46th, 365.6 million kilowatt-hours of green power used each year.
  • Houston-based Solvay America, ranked 61st, 220 million kilowatt-hours of green power used each year.
  • Plano-based Cinemark USA, ranked 95th, 120.2 million kilowatt-hours of green power used each year.

Two Texas schools appear on the list of the top colleges and universities for use of green power:

  • University of North Texas in Denton, ranked 17th, 80.3 million kilowatt-hours of green power used each year.
  • Fort Worth-based Tarrant County College District, ranked 25th, 57.1 million kilowatt-hours of green power used each year.

Four Texas institutions show up on the list of the top K-12 users of green power:

  • Austin ISD, ranked second, 19.8 million kilowatt-hours of green power used each year.
  • Lake Travis ISD (select schools), ranked 12th, 960,000 kilowatt-hours of green power used each year.
  • The da Vinci School in Dallas, ranked 15th, 237,990 kilowatt-hours of green power used each year.
  • The Empower School in Austin, ranked 17th, 115,314 kilowatt-hours of green power used each year.

The EPA's ranking of the largest users of green power across the country "is proof that good business practices can also benefit the environment," says James Critchfield, director of the EPA's Green Power Partnership.

Houston researchers find new eco-friendly way to preserve produce

preventing waste

Hunger impacts over 800 million people worldwide, leaving nearly 10 percent of the population suffering from chronic undernourishment. The distressing reality of food shortages co-exists in a world where 1.3 billion tons of food — nearly a third of what's produced — is wasted each year, according to the Food and Agriculture Organization of the United Nations. Rice University's scientific research team's latest discovery takes a crack at ending food shortages and improving sustainability with a common kitchen necessity: eggs.

The discovery of egg-based coating is promising to researchers, as it manages to both prolong produce shelf-life by double while impacting the environment.

"We are reducing the cost, and at the same time we are reducing the waste," says Muhammad M. Rahman, a research scientist at Rice University. "One in every eight people are hungry...on the other side, 33 percent of food is wasted."

It's no secret that overflowing landfills contribute to the climate crisis, piling high with food waste each year. While the United States produces more than seven billion eggs a year, manufacturers reject 3 percent of them. The Rice University researchers estimate that more than 200 million eggs end up in U.S. landfills annually.

According to the Environmental Protection Agency, half of all landfill gas is methane, a hazardous greenhouse gas that contributes to detrimental climate change. Landfills are the third-largest contributor to methane emissions in the country, riding the coattails of agriculture and the energy industry.

COVID-19 has upended supply chains across the nation, and in recent months food waste has become an even more pressing issue. The disruptions of consumer purchasing habits and the indefinite closures of theme parks and select restaurants put a burden on farmers who planned for larger harvests and restaurants unsure of how to adjust. With more Americans cooking at home, panic-buying from grocery stores is also playing a role in accumulating waste.

To understand the challenges of the food industry, it's important to acknowledge the biggest menace to the supply chain: perishability. Fruits and vegetables only last a few days once arriving in grocery stores due to culprits like dehydration, texture deterioration, respiration and microbial growth. Rice University researchers sought to create a coating that addresses each of these issues in a natural, cost-effective way.

Brown School of Engineering materials scientist, Pulickei Ajayan, and his colleagues, were looking for a protein to fight issues like food waste. Rahman, a researcher in Ajayan's lab, received his Ph.D. from Cornell University studying the structure-property relationship in green nanocomposites. He and his fellow researchers found that egg whites were a suitable protein that wouldn't alter the biological and physiological properties of fruit. The study published in Advanced Materials took one year and three months to complete.

According to Rahman, the egg-based coating is non-toxic, biodegradable and healthier than other alternatives on the market. Wax is one common method of fruit preservation that can result in adverse effects on gut cells and the body over time.

"Long-term consumption of wax is not actually good and is very bad for your health," says Dr. Rahman. After wax is consumed, gut cells fragment the preservatives in wax to ions. This process can have a negative impact on "membrane disruption, essential metabolite inhibition, energy drainage to restore homeostasis, and reductions in body-weight gain," according to the research abstract.

Preservation efforts like wax, modified atmospheric packaging and paraffin-based active coatings are not only more expensive and less healthy, but they also alter the taste and look of fruits.

"Reducing food shortages in ways that don't involve genetic modification, inedible coatings or chemical additives is important for sustainable living," Ajayan states in a press release.

The magic of preservation is all in the ingredients. Rice University's edible coating is mostly made from household items. Seventy percent of the egg coating is made from egg whites and yolk. Cellulose nanocrystals, a biopolymer from wood, are mixed with the egg to create a gas barrier and keep the produce from shriveling. To add elasticity to the brittle poly-albumen (egg), glycerol helps make the coating flexible. Finally, curcumin—an extract found in turmeric—works as an antibacterial to reduce the microbial growth and preserve the fruit's freshness.

The experiment was done by dipping strawberries, avocados, papayas and bananas in the multifunctional coating and comparing them with uncoated fruits. Observation during the decaying process showed that the coated fruits had about double the shelf-life of their non-coated counterparts.

For people with egg allergies, the coating can be removed simply by rinsing the produce in water. Rice University researchers are also beginning to test plant-based proteins for vegan consumers.

For its first iteration, Rahman finds that the coating shows "optimistic results" and "potential" for the future of food preservation.

"These are already very green materials. In the next phase, we are trying to optimize this coating and extend the samples from fruits to vegetables and eggs," says Rahman.

Researchers will also work to test a spray protein, making it easier for both commercial providers as well as consumers looking for an at-home coating option. From a lab in Rice University to a potential shelf life in stores, the innovation of food coating is just beginning.

National report declares Texas dim when it comes to energy efficiency

Power Problems

For a state that's home to the "Energy Capital of the World," Texas falls flat when it comes to energy efficiency. WalletHub, a personal finance site, ranked the most and least energy-efficient states, and Texas was named No. 42 of the 48 states evaluated.

The states were scored on home and auto efficiency out of an available 100 points. Home efficiency was calculated based on the ratio of total residential energy consumption to annual degree days, the days of the year in each region that require buildings to engage heating or cooling. Auto efficiency was established by factoring in the annual miles driven per year, gallons of gasoline consumed, and population. At the top of the national ranking were New York, Vermont, Utah, Rhode Island, and Massachusetts.

Texas, with its hot climate and underdeveloped public transportation systems, scored only 33.34 total points on the report. The state ranked No. 35 on home energy efficiency and No. 42 for auto energy efficiency. Texans drive over 271 billion miles annually and use over 19 billion gallons of gas, the second worst and worst rankings, respectively, among the states considered for this study.

The Environmental Protection Agency's research tells a different story of Texas' sustainability. The EPA's Green Power Partnership named its 2018 top local governments, and Texas cities claimed three spots in the top five. Houston was ranked No. 1, followed by Dallas at No. 2 and Austin at No. 5. This ranking is based on the annual green power usage — Houstonians use almost 1.1 million kilowatt hours of wind and solar energies annually.

According to the WalletHub report, each American household spends at least $2,000 annually on utilities and another $1,968 on gasoline and oil, which is up $59 from last year. New technologies and energy-efficient measures can reduce household utility costs by up to 25 percent, and a fuel-efficient car could save drivers over $700 annually, says WalletHub. The report's experts advised in properly weatherproofing homes; smart technology, such as thermostats; solar panels; and more.

Shipley Donuts launches AI-powered ordering assistant

fresh tech

Popular Houston-born doughnut chain Shipley Donuts has added a first-of-its-kind AI-powered assistant to its online ordering platform.

The new assistant can create personalized order recommendations based on individual or group preferences, according to a news release from the company. Unlike standard chatbox features, the new assistant makes custom recommendations based on multiple customer factors, including budgetary habits, individual flavor preferences and order size.

"We're not just adding AI for the sake of innovation — we're solving real customer pain points by making ordering more intuitive, personalized and efficient," Kerry Leo, Shipley Vice President of Technology, said in the release.

The system also works for larger events, as it can make individual orders and catering recommendations for corporate events and meetings by suggesting quantities and assortments based on group size, event type and budget.

According to Shipley, nearly 1 in 4 guests have completed orders with the new AI technology since it launched on its website.

“The integration of the AI ordering assistant into our refreshed website represents a significant leap forward in how restaurant brands can leverage technology to enhance the customer experience,” Leo added in the release.

Houston company wins AHA competition for pediatric heart valve design

winner, winner

Houston-based PolyVascular, which develops minimally invasive solutions for children with congenital heart disease, was named the overall winner of the American Heart Association’s annual Health Tech Competition earlier this month.

The company was founded in 2014 by Dr. Henri Justino and Daniel Harrington and was part of TMCi's 2017 medical device cohort. It is developing the first polymer-based transcatheter pulmonary valve designed specifically for young children, allowing for precise sizing and redilation as the child grows while also avoiding degradation. PolyVascular has completed preclinical studies and is working toward regulatory submissions, an early feasibility study and its first-in-human clinical trial thanks to a recent SBIR grant from the National Heart, Lung, and Blood Institute.

With the new AHA honor, PolyVascular will be invited to join the association’s Center for Health Technology & Innovation Innovators’ Network, which connects entrepreneurs, providers and researchers to share and advance innovation in cardiovascular and brain health.

“This is a tremendous honor for PolyVascular—we’re especially proud to bring hope to families and children living with congenital heart defects,” Justino said in a news release. “Our technology—a minimally invasive valve that can be expanded over time to grow with the child—has the potential to dramatically reduce the need for repeated open-heart surgeries.”

The Health Tech Competition is a live forum for health care innovators to present their digital solutions for treating or preventing cardiovascular diseases and stroke.

Finalists from around the world addressed heart failure, hypertension, congenital heart defects and other issues that exist in cardiovascular, brain and metabolic health. Solutions were evaluated on the criteria of validity, scientific rigor and impact.

The judges included Texas-based Dr. Eric D. Peterson, professor of medicine in the division of cardiology at UT Southwestern Medical Center, and Dr. Asif Ali, clinical associate professor of cardiovascular medicine at the University of Texas Medical School in Houston and director at Cena Research Institute.

According to the American Heart Association, nearly half of U.S. adults live with some form of cardiovascular disease or stroke.

“The American Heart Association plays a pivotal role in advancing innovative care pathways, and we’re excited that our solution aligns with its guidelines and mission,” Justino said in a news release. “It’s time these life-changing technologies reach the youngest patients, just as they already do for adults.”

EO Houston is where ambitious founders go to scale smarter

Don't Go It Alone

Scaling a business from early traction into true growth is one of the most exciting — and punishing — chapters of entrepreneurship. Houston founders know this better than most. Our city is built on ambition: fast-moving industries, talent from around the world, and opportunities that expand as large as the Texas sky.

But as many entrepreneurs eventually learn, scaling isn’t simply “more of what worked.” It requires new systems, new thinking, and often, a new version of the founder. Even the most capable founders eventually face decisions, pressures, and turning points that only other entrepreneurs can truly understand.

Entrepreneurs’ Organization, a global peer-to-peer network of more than 18,000 business owners across 220 chapters in 75+ countries, exists for exactly this stage. One of the largest chapters in the organization, EO Houston brings that global community to life locally, offering founders the connection, learning, and accountability needed to grow sustainably and to grow up as leaders.

A community where founders learn at the highest level
The real value of EO emerges in the lived experiences of other entrepreneurs. When Houston-area founders talk about the moments growth nearly broke their companies, a universal theme appears: you can’t do it alone.

EO Houston member Robert De Los Santos of Sky High Party Rentals learned this the hard way when rapid post-COVID growth made expansion feel limitless — until it wasn’t.

“After COVID, we doubled every year and assumed inventory was the limit. In 2023 we overbought, only to realize demand had peaked. That taught us a hard truth: growth in one city has ceilings. Expanding into Austin and Dallas — the Texas Triangle — gave us new markets to put our inventory to work while we figured out how to penetrate Houston better. The challenge shifted from a strategy of ‘buy more units for demand’ to learning how to tackle the challenges of ‘leading across cities.’”

Founders often enter EO exhausted from trying to maintain control as things grow more complex. Many discover, like Jarred King of Summit Firms, that scaling requires the difficult shift from doing everything to building the team that can.

“We grew quickly because of my network, relationships, and hustle… but I was doing all the work,” King says. “I realized at that point you have to delegate — not just busy work, but important decisions to your key team, as well as set up really effective SOPs.”

“The uncomfortable truth is that you are no longer the best person for most jobs in your company," agrees Darren Randle of Houston Tents & Events. "Your inability to delegate or hire people smarter than you in key leadership and management level roles will become the single biggest drag on the entire business. You have to accept that your original 'hustle' is now a scalability risk."

Making hard decisions, such as walking away from customers or contracts, can feel like less of a sting when you know others have also been faced with tough choices. Aaron Gillaspie of West U's My Salon Suite recalls, “You can’t be everything to everyone, it’s ok to say no, and just understand some customers aren’t the right fit. It’s a two way street and both must win.”

Perspective is perhaps the most important reality check that members find at EO.

“Bigger volume will not make problems go away — you just got to get used to walking the tightrope," says Roger Pombrol of Emerald Standard. "Develop a system for good balance and do not freak out. Scared is no way to live your life. It’s ok if you fall. Your family will still love you. Money is just money. Love is love. The world tries to make you conflate them, but don’t."

Actionable insights from entrepreneurs who’ve already scaled
Conversations like these are happening every month inside EO Forum Meeting. Each EO chapter is divided into several small Forums. These confidential, committed group of 7–10 entrepreneurs who meet to share the real five percent of what they’re experiencing. It’s not advice, but experience — shared candidly, respectfully, and with the kind of vulnerability that leads to breakthroughs.

What makes Forum so impactful is the honesty it draws out. Entrepreneurs are often surrounded by employees, partners, and even family members who rely on them for answers, but seldom do they have a group where vulnerability is not only welcomed, but expected.

Learning experiences that match your ambition
EO supports that growth far beyond peer groups. Through the organization’s global partnerships with institutions like Harvard, Oxford, and INSEAD, Houston members gain access to executive-level learning experiences designed specifically for entrepreneurs.

These programs help founders step out of the day-to-day and think strategically about competitive advantage, innovation, and organizational leadership. Paired with ongoing learning through EO Jumpstart, Nano Learning, and its global library of member-created content, founders stay informed, challenged, and ahead of emerging trends.

And through global communities — ranging from EO Women and EO Under 35 to industry-specific groups — Houston members tap into expertise that spans continents and sectors. Whether someone is navigating M&A, exploring international expansion, or integrating new technologies, the right perspectives are always within reach.

What truly distinguishes EO Houston, however, is its culture. Houston’s entrepreneurial landscape is uniquely diverse and resilient, filled with founders who are hungry to build, innovate, and elevate the city’s business community. EO Houston amplifies that spirit, creating relationships that are as supportive as they are strategic. Many members describe the chapter not simply as a network, but as a catalyst for becoming better leaders, better thinkers, and — just as importantly — better human beings.

Your next level starts here
For entrepreneurs who are ready to scale—beyond their first million, beyond their current comfort zone, and toward a future that requires sharper leadership and stronger community—EO Houston offers an unmatched platform. It is a place where ambitious founders grow faster, think bigger, and gain the confidence to take bold next steps.

If you’re ready to elevate your business and your leadership alongside people who understand the journey, EO Houston is ready to welcome you. Your next level starts with the peers who can help you reach it. Learn more and become a member here.
