A large group of Republican attorneys general on Monday took legal action against the Biden administration and California over new emissions limits for trucks.

Nebraska Attorney General Mike Hilgers is leading the group of GOP attorneys general who filed a petition with the U.S. Court of Appeals for the District of Columbia Circuit to overturn an Environmental Protection Agency rule limiting truck emissions.

Texas joined Nebraska's latest action against the EPA, along with Alabama, Florida, Georgia, and several others.

A separate lawsuit against California claims a phased-in ban on internal-combustion trucks is unconstitutional and will hurt the U.S. economy.

Hilgers in a statement said the EPA and California rules “will devastate the trucking and logistics industry, raise prices for customers, and impact untold number of jobs across Nebraska and the country.”

“There’s not one trucking charging station in the state of Nebraska,” Hilgers later told reporters. “Trying to take that industry, which was built up over decades with diesel and fossil fuels-based infrastructure, and transforming it to an electric-based infrastructure – it’s probably not feasible.”

EPA officials have said the strict emissions standards will help clean up some of the nation’s largest sources of planet-warming greenhouse gases.

The new EPA rules are slated to take effect for model years 2027 through 2032, and the agency has said they will avoid up to 1 billion tons of greenhouse gas emissions over the next three decades.

Emissions restrictions could especially benefit an estimated 72 million people in the U.S. who live near freight routes used by trucks and other heavy vehicles and bear a disproportionate burden of dangerous air pollution, the agency has said.

A spokesperson for the EPA declined to comment on the legal challenge to the new rules Monday, citing the pending litigation.

California rules being challenged by Republican attorneys general would ban big rigs and buses that run on diesel from being sold in California starting in 2036.

An email seeking comment from California’s Air Resources Board was not immediately answered Monday.

California has been aggressive in trying to rid itself of fossil fuels, passing new rules in recent years to phase out gas-powered cars, trucks, trains and lawn equipment in the nation’s most populous state. Industries, and Republican leaders in other states, are pushing back.

Another band of GOP-led states in 2022 challenged California’s authority to set emissions standards that are stricter than rules set by the federal government. The U.S. Court of Appeals for the District of Columbia Circuit last month ruled that the states failed to prove how California’s emissions standards would drive up costs for gas-powered vehicles in their states.

Solidec secures pre-seed funding from Houston VC firm

fresh funding

Houston-based Flathead Forge Fund 1 has invested in Houston startup Solidec, which specializes in modular onsite chemical manufacturing.

The investment was part of Solidec’s recent round of more than $2 million in pre-seed funding. The amount of Flathead Forge’s investment wasn’t disclosed.

“Flathead Forge brings exactly the kind of domain-specific capital and operational network that a company at our stage needs. Their focus on water and critical minerals makes this a genuinely strategic relationship,” Ryan DuChanois, co-founder and CEO of Solidec, said in a news release.

Other investors in the round included New Climate Ventures, Collaborative Fund, Echo River Capital, Ecosphere Ventures, Plug and Play Ventures, Safar Partners and Semilla Climate Capital.

Solidec produces industrial chemicals, including hydrogen peroxide, formic acid and acetic acid, using only air, water and electricity. Its modular reactors eliminate the need for energy-intensive production and long-haul distribution.

“Solidec’s platform cuts cost, emissions, and supply-chain fragility at the source,” Douglas Lee, managing director of Flathead Forge, added in the statement.

DuChanois said in an email that the company plans to use the funding to "scale (its) modular chemical manufacturing platform."

Solidec recently announced a pilot project with Lynas Rare Earths, the world’s only commercial producer of separated light and heavy rare earth oxides outside China, for production of hydrogen peroxide for a Lynas facility in Australia.

Solidec, a member of Greentown Labs Houston, spun out of associate professor Haotian Wang’s lab at Rice University in 2024. Wang focuses on developing new materials and technology for energy and environmental uses, such as energy storage and green synthesis.

Greentown Labs names new COO, appoints new Head of Houston

new leaders

Greentown Labs has reshuffled its leadership, elevating Houston leaders into new roles.

Lawson Gow was named COO of the Houston- and Boston-based climatech incubator in February 2026. In his new role, he will focus on optimizing Greentown's structure, building new internal and external systems and developing a plan for growth.

Gow was named Head of Houston in July. He previously founded The Cannon, a coworking space with eight locations in the Houston area, with additional partner spaces. He also recently served as managing partner at Houston-based investment and advisory firm Helium Capital. Gow is the son of David Gow, founder of Energy Capital's parent company, Gow Media.

Kelsey Kearns, who previously served as Director of Community Strategy at Greentown, was named as Gow's replacement in the Houston-focused role. As the new Head of Houston, she will lead daily operations, work to connect the city's climate and innovation ecosystem and founders, strengthen partnerships and accelerate solutions.

"I'm honored and grateful to step into this new role," Kearns said in an email. "My goal is for Greentown to thrive so our founders can thrive! That means supporting their connection to the capital, pilots, and customers they need to grow while building partnerships across Houston's innovation ecosystem. I want Greentown Houston to become the playbook for every future Greentown expansion."

Before joining Greentown Houston, Kearns served as director of business development at Howdy.com, an Austin-based technology staffing company.

"Kelsey is such a perfect fit to lead Greentown Houston," Gow added in an email. "She's deeply passionate about the entrepreneurial community here and has worked throughout and across the ecosystem for years. She's built an awesome dream team here and has helped reinvigorate Greentown's presence and role in Houston's innovation economy."

Earlier this year, Greentown also named Julia Travaglini as the Head of its Boston incubator. Travaglini has held multiple leadership roles at Greentown since 2016. The organization named Georgina Campbell Flatter as its new CEO in early 2025.

Texas sees 5th highest surge in gas prices in the U.S. since 2025

Pay at the Pump

Residents all around Texas are seeing soaring prices for regular and diesel fuel in 2026.

In fact, the Lone Star State has seen the fifth-highest percentage increase in gas prices in the country from April 2025 to April 2026, a just-released SmartAsset study has found. The current cost of a regular gallon of gas is 36.1 percent higher now than it was a year ago, and diesel is 60.9 percent more expensive.

The report, "Gas Prices Hit Records in 2026: State by State Breakdown," compared average gas prices from AAA from April 1, 2025 and April 1, 2026 and calculated the one-year change across all 50 states. The study looked at the price of a gallon of regular, premium, and diesel.

According to AAA, the cost of a regular gallon of gas in Texas at the start of April was $3.77, while premium is $4.62 per gallon. Diesel ticked over $5 a gallon — ouch — at $5.11.

Houston gas prices aren't much cheaper than the statewide average. A gallon of regular costs up to $3.76 at some Houston-area pumps, and diesel is $5.05 per gallon. AAA says the highest recorded average price for gas in the city was in June 2022, when a gallon of regular cost $4.68 and diesel cost $5.24.

Though Texas' gas prices are continuing to climb, it ranks 35th in the national ranking of states with the highest cost for regular gas as of April 2026. Texas' diesel prices are the 14th highest nationwide.

With the national average price for gas at $4.06, SmartAsset said the sudden surge in prices can be attributed to the United States' war on Iran, and "subsequent pressure on the Strait of Hormuz."

"Many states have experienced a 33 percent year-over-year increase in the cost of a gallon of regular gas – and in some places it’s even higher," the report's author wrote. "Commercial and public programs may be feeling similarly pinched, with diesel prices upwards of $6.00 per gallon in many states."

California currently has the highest average price for regular and diesel — $5.89 per gallon and $7.52 per gallon, respectively.

Arizona leads the nation with the highest one-year increase in gas prices. Regular gas in the Grand Canyon State is nearly 38 percent more expensive than it was last year, at $4.70 per gallon, and diesel is about 69 percent higher at $6.04 for a gallon.

The state with the cheapest gas prices in April is Oklahoma, where regular costs $3.27 per gallon, premium is $3.97, and diesel is $4.49.
