People looking to travel to a sustainable city probably don’t have Texas spots at the top of their lists. Images of oil, cars, and blasting air conditioners spring up. The Texas power grid, no one need remind us, is barely hanging on.

But Texas blew other states away for lowest carbon footprint per capita, landing Houston at the top of the list compiled by travel blog Park Sleep Fly. Austin followed (No. 3), then San Antonio (No. 4) and Dallas (No. 9). Only Florida appeared twice in the top 10, and none matched Texas with four cities.

Among the 50 most visited in the U.S., those with the lowest carbon footprint are:

1. Houston
2. Los Angeles
3. Austin
4. San Antonio
5. Tampa, Florida
6. Salt Lake City
7. Phoenix
8. Miami
9. Dallas
10. Portland, Oregon

Houston is not exactly a green place, with less-than-ideal utilization of public transportation. It and Dallas tied for third place among least sustainable cities in the same report.

“Public transit isn’t the most popular mode of transportation in Houston, but it does exist,” an online publication called TripSavvy drably admits. The city takes credit for employing “nearly one third” of the nation’s oil and gas extraction workers.

On the renewable side, however, Houston claims more than 100 solar energy companies, and at least half of its corporate research and development centers pursue “energy technology and innovation.” And its huge population spreads the load, leaving only 14.6 metric tons of carbon dioxide per resident — the same as Los Angeles. Big cities seem to have an advantage in this rating system.

Austin is just behind Houston at 15 metric tons per capita, neck-and-neck with San Antonio at 15.2. These two cities have smaller populations to distribute their total footprint, but are generally seen as eco-friendly. Austin got a big head start in 1991 with the introduction of the Austin Energy Green Building program — the first of its kind in the whole country — which created an evaluation system for individual building sustainability that’s still in use. Dallas' carbon footprint is the largest of the Texas cities in the ranking, at 16.5 metric tons per capita.

As such a multifaceted issue (especially tied up in economic concerns), sustainability is hard to pin down from city to city. The multiplicity of this list is yet another indicator that Texas as a whole is a much more nuanced place than many people think.

Houston space tech companies land $25 million from Texas commission

Out Of This World

Two Houston aerospace companies have collectively received $25 million in grants from the Texas Space Commission.

Starlab Space picked up a $15 million grant, and Intuitive Machines gained a $10 million grant, according to a Space Commission news release.

Starlab Space says the money will help it develop the Systems Integration Lab in Webster, which will feature two components — the main lab and a software verification facility. The integration lab will aid creation of Starlab’s commercial space station.

“To ensure the success of our future space missions, we are starting with state-of-the-art testing facilities that will include the closest approximation to the flight environment as possible and allow us to verify requirements and validate the design of the Starlab space station,” Starlab CEO Tim Kopra said in a news release.

Starlab’s grant comes on top of a $217.5 million award from NASA to help eventually transition activity from the soon-to-be-retired International Space Station to new commercial destinations.

Intuitive Machines is a space exploration, infrastructure and services company. Among its projects are a lunar lander designed to land on the moon and a lunar rover designed for astronauts to travel on the moon’s surface.

The grants come from the Space Commission’s Space Exploration and Aeronautics Research Fund, which recently awarded $47.7 million to Texas companies.

Other recipients were:

  • Cedar Park-based Firefly Aerospace, which received $8.2 million
  • Brownsville-based Space Exploration Technologies (SpaceX), which received $7.5 million
  • Van Horn-based Blue Origin, which received $7 million

Gwen Griffin, chair of the commission, says the grants “will support Texas companies as we grow commercial, military, and civil aerospace activity across the state.”

State lawmakers established the commission in 2023, along with the Texas Aerospace Research & Space Economy Consortium, to bolster the state’s space industry.

Houston experts: Can AI bridge the gap between tech ambitions and market realities?

guest column

Despite successful IPOs from the likes of Ibotta, Reddit and OneStream, 2024 hasn’t provided the influx of capital-raising opportunities that many late-stage tech startups and venture capitalists (VCs) have been waiting for. Since highs last seen in 2021—when 90 tech companies went public—the IPO market has been effectively frozen, with just five tech IPOs between January and September 2024.

As a result, limited partners have not been able to replenish investments and redeploy capital. This shifting investment landscape has VCs and tech leaders feeling stuck in a holding pattern. Tech leaders are hesitant to enter the public markets because valuations are down 30 percent to 40 percent from 2021, which is also making late-stage fundraising more challenging. After all, longer IPO timelines mean fewer exit opportunities for VCs and reduced capital from institutional investors who are turning toward shorter-term investments with more liquid exit options.

Of course, there’s always an exception. And in the case of a slowed IPO market, a select slice of tech companies—AI-related companies—are far outperforming others. While not every tech startup has AI software or infrastructure as their core offering, most can benefit from using AI to revise their playbook and become more attractive to investors.

Unlocking Growth Potential with AI

While overall tech startup investment has slowed, the AI sector burns bright. This presents an opportunity for companies that strategically leverage AI, not just as a buzzword but as a tool for genuine growth and differentiation. Imagine a future where AI-powered insights unlock unprecedented efficiency, customer engagement and a paradigm shift in value creation. This isn’t just about weathering the current storm of reduced access to capital; it’s about emerging stronger, ready to lead the next wave of tech innovation.

Here's how to navigate the AI frontier and unlock its potential:

  1. Understand that data is the foundation of AI success. AI is powerful, but it’s not magic. It thrives on high-quality, interconnected data. Before diving into AI initiatives, companies must assess their data health. Is it structured in a way that AI can understand? Does it go beyond raw numbers to capture context and meaning—like customer sentiment alongside sales figures? Rethinking data infrastructure is often the crucial first step.
  1. Focus on amplifying strengths, not reinventing the wheel. The allure of AI can tempt companies into pursuing radical reinvention. However, a more effective strategy is to leverage AI to enhance existing strengths and address core customer needs. Why do customers choose your company? How can AI supercharge your value proposition? Consider Reddit’s strategic approach: They didn’t overhaul their platform before their 2024 IPO. Instead, they showcased the value of their vast online communities as fertile ground for AI development, leading to a remarkable first-day stock surge of 48 percent.

  2. Use AI as a customer-centric force multiplier. Companies with a deep understanding of their customer base are primed for AI success. By integrating AI into the very core of their product or service—the reason customers choose them—they can create a decisive competitive advantage based on delivering tangible customer value.

From Incremental Gains to Transformative Growth

This practical, customer-centric approach has the potential to help companies generate immediate growth while laying the foundation for future reinvention. By leveraging AI to optimize operations, deepen customer relationships, and redefine industry paradigms, late-state tech startups can not only survive but thrive in a dynamic market. The future belongs to those who embrace AI not as a destination but as a continuous journey of innovation and growth.

Houston joint venture secures $5.2M for AI-powered methane tracking tech

Fresh Funds

Houston-based Envana Software Solutions has received more than $5.2 million in federal and non-federal funding to support the development of technology for the oil and gas sector to monitor and reduce methane emissions.

Thanks to the work backed by the new funding, Envana says its suite of emissions management software will become the industry's first technology to allow an oil and gas company to obtain a full inventory of greenhouse gases.

The funding comes from a more than $4.2 million grant from the U.S. Department of Energy (DOE) and more than $1 million in non-federal funding.

“Methane is many times more potent than carbon dioxide and is responsible for approximately one-third of the warming from greenhouse gases occurring today,” Brad Crabtree, assistant secretary at DOE, said in 2024.

With the funding, Envana will expand artificial intelligence (AI) and physics-based models to help detect and track methane emissions at oil and gas facilities.

“We’re excited to strengthen our position as a leader in emissions and carbon management by integrating critical scientific and operational capabilities. These advancements will empower operators to achieve their methane mitigation targets, fulfill their sustainability objectives, and uphold their ESG commitments with greater efficiency and impact,” says Nagaraj Srinivasan, co-lead director of Envana.

In conjunction with this newly funded project, Envana will team up with universities and industry associations in Texas to:

  • Advance work on the mitigation of methane emissions
  • Set up internship programs
  • Boost workforce development
  • Promote environmental causes

Envana, a software-as-a-service (SaaS) startup, provides emissions management technology to forecast, track, measure and report industrial data for greenhouse gas emissions.

Founded in 2023, Envana is a joint venture between Houston-based Halliburton, a provider of products and services for the energy industry, and New York City-based Siguler Guff, a private equity firm. Siguler Gulf maintains an office in Houston.

“Envana provides breakthrough SaaS emissions management solutions and is the latest example of how innovation adds to sustainability in the oil and gas industry,” Rami Yassine, a senior vice president at Halliburton, said when the joint venture was announced.
