What to know about the new emission inspection to register your car in Texas

Beginning January 1, 2025, Texas vehicle owners will no longer need to obtain a safety inspection prior to vehicle registration. House Bill 3297, passed during the 88th Legislature in 2023, eliminates the safety inspection program for non-commercial vehicles.

Under the new law, the $7.50 fee that drivers had to pay as a safety inspection fee has not gone away. It now appears on your registration notice under a new name: "Inspection Program Replacement Fee."

This name change comes courtesy of the legislature, who want to keep collecting this fee because the funds go to state programs such as construction and expansion of state highways — funds they previously collected from the Safety Inspection Fee. Continue reading.

As the holiday season comes to a close, you might be wondering what's the most sustainable way to say goodbye to your beloved Christmas tree. A city program has your solution.

The city of Houston's Solid Waste Management Department has opened 22 residential tree drop-off recycling locations throughout the area. Locals can take their live trees to one of these centers across the city, where they will be repurposed for mulch or other landscape materials.

This tree recycling program, which runs Thursday, December 26, 2024, through Friday, January 24, 2025, is part of the city of Houston for the 34rd annual tree mulching event. Continue reading.

Verde Clean Fuels announced the entry into a stock purchase agreement with Cottonmouth Ventures, a wholly-owned subsidiary of Diamondback Energy.

With the deal, Midland, Texas-based Cottonmouth will make a $50 million equity investment into Houston-based Verde.

The investment will consist of the purchase of 12.5 million shares of Verde’s Class A common stock at a purchase price of $4.00 per share. Closing of the investment is anticipated to occur during the first quarter of the new year, which will be subject to satisfaction of customary closing conditions. The investment would represent the second investment by Cottonmouth in Verde over the past two years, which would equal a total investment of $70 million. This would make Cottonmouth the second largest shareholder of Verde.

“We are pleased to further our relationship with Diamondback and continue advancing our plans to deploy our technology through the development of commercial production plants,” Ernest Miller, CEO of Verde, says in a news release. “Diamondback is a strategic industry partner at the forefront of bringing sustainable operational practices to the oilfield and supporting the overall transition to clean energy.” Continue reading.

Houston's William P. Hobby Airport is generating its own clean energy.

Houston Aiports announced that Hobby's red garage is now home to a "solar canopy" that is producing energy at 100 percent capacity to power daily operations. The photovoltaic (PV) solar system generated more than 1.1 gigawatt-hours of electricity in testing, and is expected to produce up to 1 megawatt-hour now that it's operating at full power.

“This project is proof that sustainability can be practical, visible and directly tied to the passenger experience,” Jim Szczesniak, director of aviation for Houston Airports, said in a news release. “Passengers now park under a structure that shields their cars from the Texas sun while generating clean energy that keeps airport operations running efficiently, lowering overall peak demand electrical costs during the day and our carbon footprint. It’s a win for travelers, the city and the planet.”

The project was completed by Texas A&M Engineering Experiment Station (TEES) and CenterPoint Energy. It's part of Houston Airport's efforts to reduce carbon emissions by 40 percent over its 2019 baseline.

In a separate announcement, the airport system also shared that it recently reached Level 3 in the Airports Council International (ACI) Airport Carbon Accreditation program after reducing emissions by 19 percent in three years. This includes reductions at George Bush Intercontinental Airport (IAH), Hobby and Ellington Airport/Houston Spaceport.

The reductions have come from initiatives such as adding electric vehicles to airport fleets, upgrading airfield lighting with LED bulbs, adding smarter power systems to terminals, and improving IAH's central utility plant with more efficient equipment. Additionally, the expansion to Hobby's West Concourse and renovations at IAH Terminal B incorporate cleaner equipment and technology.

According to Houston Airports, from 2019 to 2023:

  • IAH reduced emissions by 17 percent
  • Hobby reduced emissions by 32 percent
  • Ellington Airport reduced emissions by 4 percent

"I see firsthand how vital it is to link infrastructure with sustainability,” Houston City Council Member Twila Carter, chair of the council’s Resilience Committee, said in the release. “Reducing carbon emissions at our airports isn’t just about cleaner travel — it’s about smarter planning, safer communities and building a Houston that can thrive for generations to come.”
