A progressive business group sued Texas on Thursday over a 2021 law that restricts state investments in companies that, according to the state, “boycott” the fossil fuel industry.

The American Sustainable Business Coalition filed suit against Attorney General Ken Paxton and Comptroller Glenn Hegar, alleging that the law, Senate Bill 13, constitutes viewpoint discrimination and denies companies due process, in violation of the First and Fourteenth Amendments. The group asked a federal judge in Austin to declare the statute unconstitutional and permanently block the state from enforcing it.

“Texas has long presented itself as a business-friendly state where limited state regulation facilitates the ability of businesses to conduct themselves as they see fit,” lawyers for the group wrote. “Yet in 2021, the Legislature passed SB 13 to coerce and punish businesses that have articulated, publicized, or achieved goals to reduce reliance on fossil fuels.”

Known as the “anti-ESG law” — which stands for “environmental, social and governance” — Senate Bill 13 requires state entities, including state pension funds and the enormous K-12 school endowment, to divest from companies that have reduced or cut ties with the oil and gas sector and that Texas officials deem antagonistic to the fossil fuel industry.

In approving the legislation, Republican officials looked to protect Texas oil and gas companies and to bite back at Wall Street investors pulling financial support from the industry in an effort to incorporate climate risk into their investments and respond to pressure to divest from fossil fuels, which play an outsized role in accelerating the climate crisis.

In March, Texas Permanent School Fund, Austin, cut ties with BlackRock, which managed roughly $8.5 billion of the $52.3 billion endowment and which was listed by Texas as one of the companies that should not handle state business.

The statute defines “boycott” as, “without an ordinary business purpose, refusing to deal with, terminating business activities with, or otherwise taking any action that is intended to penalize, inflict economic harm on, or limit commercial relations with” a fossil fuel company. It also prohibits state agencies from doing business with a firm unless it affirms that it does not boycott energy companies. And it charges the state comptroller with preparing and maintaining a blacklist of companies based on “publicly available information” and “written verification” from the company.

In a statement, Hegar, the comptroller, called the lawsuit an “absurd” attempt to “force the state of Texas and Texas taxpayers to invest their own money in a manner inconsistent with their values and detrimental to their own economic well-being.”

“This left-wing group suing Texas,” he said, “is hiding their true intent: to force companies to follow a radical environmental agenda that is often contrary to the interests of their shareholders and to punish those companies that do not fall into lockstep and put politics above earnings.”

Paxton’s office did not immediately reply to a request for comment.

Texas has blacklisted more than 370 investment firms and funds, including BlackRock and funds within major banks like Goldman Sachs and J.P. Morgan. BlackRock, among other companies, pushed back on its designation as “boycotting” fossil fuels, calling the decision “not a fact-based judgment” and citing over $100 billion in investments in Texas energy companies.

“Elected and appointed public officials have a duty to act in the best interests of the people they serve,” a BlackRock spokesperson said at the time. “Politicizing state pension funds, restricting access to investments, and impacting the financial returns of retirees, is not consistent with that duty.”

In Thursday’s suit, the American Sustainable Business Coalition argued that the physical and financial risks posed by climate change are a legitimate investment and business consideration and cause for efforts to reduce carbon emissions.

The group said the Texas law was enacted to go after what Republican lawmakers saw as a “burgeoning fossil fuel discrimination movement,” and that it effectively “infringes rights of free speech and association under a scheme of politicized viewpoint discrimination” and allows Texas officials to “punish companies they believe are insufficiently supportive of the fossil fuel industry.”

The group argued that the law penalizes companies for their energy policies and membership in certain business associations, and compels them to adopt positions that align with Texas officials “as a condition” of doing business with state entities.

The suit also alleged that the law violates companies’ right to due process because vagueness in the statute “encourages arbitrary enforcement” and fails to provide blacklisted companies a fair process to contest their designation.

Texas blacklisted “the flagship investment funds” of Etho Capital and Sphere, two climate-focused firms represented by the American Sustainable Business Coalition, according to the lawsuit.

“Among ASBC’s many projects are efforts to encourage sustainable investing and sustainable business practices,” the lawsuit reads. “These are all cornerstones of the modern Texas economy. Yet, SB 13 takes aim at, and punishes, companies that speak about, aspire to, and achieve this goal.”

Houston cleantech company closes $12M seed round

fresh funding

Houston-based Helix Earth Technologies has closed a $12 million Seed 2 funding round to scale manufacturing of its energy-efficient commercial HVAC add-on technology.

Veriten, a Houston-based energy investment firm, led the round. Rua Ventures, Carnrite Ventures, Skywriter LLC and Textbook Ventures also participated.

Helix Earth—which was founded based on NASA technology, spun out of Rice University and has been incubated at Greentown Labs—is developing high-efficiency retrofit dehumidification systems that aim to reduce the energy consumption of commercial HVAC units. The company reports that its technology can lead to "healthier indoor air, lower energy bills, reduced building maintenance, and more comfortable spaces for building owners and occupants."

"Building owners are dealing with rising energy costs, uncontrolled humidity, and aging infrastructure with no viable, cost-effective path forward. We are in the field today solving these problems for commercial customers, and this capital puts us on an aggressive path to scale,” Rawand Rasheed, Helix Earth co-founder and CEO, said in a news release.

“The strength of this round reinforces our team's conviction that we can transform innovation-starved sectors with transformational solutions that deliver order-of-magnitude improvements to owners and operators, for both their bottom line and the environment,” Rasheed added.

Maynard Holt, Veriten’s founder and CEO, said that the investment firm is tripling its investment in Helix Earth.

"The team has built breakthrough technology with real applicability across multiple industries,” Holt said in the release. “Their first product will have an immediate and measurable impact on our energy system, and they are already pursuing adjacent innovations to help heavy industries operate more efficiently and with less waste. This is a well-rounded team with a proven track record of strong execution and disciplined capital management.”

Helix Earth also closed a $5.6 million seed funding round in 2024, led by Veriten.

Last year, the company secured a $1.2 million Small Business Innovation Research (SBIR) Phase II grant and won in the Smart Cities, Transportation & Sustainability contest at the 2025 SXSW Pitch Showcase. Rasheed was also named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

SLB and NVIDIA expand partnership to scale AI across energy sector

AI partnership

Houston-based energy technology company SLB has expanded its 18-year tech collaboration with chipmaker NVIDIA to include the development of an “AI factory for energy.”

Through their partnership, SLB and NVIDIA will create AI infrastructure and models built around SLB’s existing digital platforms to help energy companies scale AI for data and operations.

In addition to the development of the “AI factory,” SLB will:

  • Provide modular design services to enhance NVIDIA’s blueprint for building, launching and operating gigawatt-scale AI data centers. In this case, modular design involves manufacturing data center components off-site.
  • Use NVIDIA’s AI infrastructure to improve the processing of large datasets and AI models across SLB’s digital platforms.

Energy companies generate vast amounts of operational data, which can slow down and silo decision-making, SLB says. By combining NVIDIA’s Omniverse libraries and its Nemotron open models with SLB’s digital and AI platforms, the companies aim to more rapidly transform data into actionable insights.

Omniverse libraries are sets of prebuilt 3D elements, such as objects, surfaces and interactive features, that make it easier to construct detailed virtual spaces without having to design everything manually. They’re commonly used for building immersive environments, digital replicas of real-world systems and simulation scenarios.

Nemotron open models are AI models that are freely available to download and modify. Instead of relying on a hosted service, you can run them on your own infrastructure and tailor them to fit specific needs.

Vladimir Troy, vice president of AI infrastructure at NVIDIA, says the energy sector is at the forefront of AI driving a “new industrial revolution.”

“The winners in AI will be companies with the best data, the deepest domain expertise, and the ability to scale,” Demos Pafitis, SLB’s chief technology officer, added. “By collaborating with NVIDIA to advance modular data center construction and harness our domain expertise and digital platforms, we’re enabling the energy industry to deploy AI at scale and transform operational data into smarter decisions.”
