A new report underscores an “urgent need” for health care systems in the Houston area to combat climate change and avoid an environmental “code blue.”

“By adopting collaborative strategies and leveraging technological innovations, health care providers can play a pivotal role in safeguarding the health of Houston’s residents against the backdrop of an evolving climate landscape,” says the report, published by the Center for Houston’s Future.

Among the report’s recommendations are:

  • Advocate for policies that promote decarbonization.
  • Create eco-friendly spaces at hospitals and in low-income communities, among other places.
  • Recruit “champions” among health leaders and physicians to help battle climate change.
  • Establish academic programs to educate health care professionals and students about climate health and decarbonization.
  • Bolster research surrounding climate change.
  • Benchmark, track, and publish statistics about greenhouse gas emissions “to foster accountability and reduce environmental impacts of the health care sector.” The report notes that the U.S. health care sector emits 8.5 percent of the country’s greenhouse gases.

“By embracing collaborative strategies, acting with urgency and implementing sustainable practices, our region’s health care providers can play a pivotal role in creating a healthier, more resilient Houston,” says Brett Perlman, outgoing president and CEO of the Center for Houston’s Future. “If we work together, given all the collective wisdom, resources and innovation concentrated in our medical community, we can tackle the challenges that are confronting us.”

The report highlights the threat of climate-driven disasters in the Houston area, such as extreme heat, floods, and hurricanes. These events are likely to aggravate health issues like heatstroke, respiratory illnesses, cardiovascular diseases, and insect-borne diseases, says the report.

St. Luke’s Health, a nonprofit health care system with 16 hospitals in the Houston area and East Texas, provided funding for the report.

City of Houston issues report highlighting progress of climate, sustainability plans

checking in

Houston is making strides in its commitment to combat climate change and build a more resilient future for its residents, according to a recent report.

Three years after Resilient Houston and the Climate Action Plan launched in 2020, the Mayor’s Office of Resilience and Sustainability, in collaboration with other departments, has issued a report on the progress of both plans.

"The creation of the Mayor's Office of Resilience and Sustainability (MORS) as a combined office in October 2021 is a visionary and bold step that brings a holistic perspective to the practice of resilience and sustainability in Houston," Priya Zachariah, chief resilience and sustainability officer, writes in the report.

"When Houston talks about resilience – it means building capacity in our most vulnerable communities to respond, grow, and thrive in the face of climate shocks and stressors," she continues. "When Houston talks about sustainability – it means reducing greenhouse gas (GHG) emissions, but it also means energy affordability, energy reliability, and energy access for everyday Houstonians."

The report identified some of the biggest wins within the city's plans, including highlighting that 172 out of 201 Resilient Houston sub-actions and 69 out of 96 Climate Action Plan actions have been completed or are in progress. The combined efforts have led to a series of accomplishments over the past year that are driving Houston toward becoming a more sustainable, equitable, and climate-resilient city.

“Earth Day HTX 2023 marked three years of laser-focused cooperation between all city departments and our dedicated community partners to push forth initiatives for a cleaner, greener Houston and I’m proud to say that we are exceeding expectations mapped out in these two plans,” Mayor Sylvester Turner says in a statement. “We track 30 measurable goals and are transparent with where we are on each one of them. We are on track to meet or exceed almost every goal and even though this is my last year in office, the wheels are in motion for future administrations to continue building on this success.”

One of the highlights from the report is the city's reduction of greenhouse gas emissions. The greenhouse gas emissions inventory for 2020 showed a notable 10 percent reduction from the baseline established in 2014.

The city's dedication to sustainability and transparency has also been recognized by external organizations. The Carbon Disclosure Project, or CDP, awarded Houston an A rating in 2022 for its efforts, including public disclosure of climate-related information, a community-wide emissions inventory, and the implementation of a climate risk and vulnerability assessment.

Furthermore, Houston has achieved the Gold designation as a Leadership in Energy and Environmental Design, or LEED, for cities by the U.S. Green Building Council (USGBC). This recognition highlights the city's commitment to green building practices and environmental responsibility.

In terms of green infrastructure, Houston has continued to prioritize tree planting efforts. Per the report, 214,134 trees were planted in 2022, contributing to a total of over 1.4 million trees since 2019. The goal is to plant 4.6 million trees by 2030, effectively reducing urban heat island effects, improving air and water quality, and providing numerous ecological benefits.

In addition, Houston has taken proactive measures to protect its natural habitats and enhance climate resilience. The City Council approved the Nature Preserve Ordinance in 2022, safeguarding 7,423 acres of natural habitat in city parks. These nature preserves will serve as vital spaces for native wildlife, mitigate flooding, and support carbon sequestration.

Houston's commitment to sustainable transportation is also evident. The city has expanded its bike infrastructure, adding 20 miles of high-comfort bike lanes in 2022. This brings the total bikeway miles to 406 out of a goal of 500 miles, promoting alternative and eco-friendly modes of transportation.

The city's efforts extend to municipal operations as well. Houston adopted a Municipal Building Decarbonization and Benchmarking policy in 2022, setting the stage for a more sustainable approach to building management. Additionally, the Houston Airport System has taken significant steps towards achieving carbon neutrality by engaging in the Airport Carbon Accreditation program.

Houston's commitment to renewable energy has also yielded positive results. The city has witnessed an increase in local solar generation, with annual solar generation reaching 148,030 MWh in 2021. Efforts to promote solar investments, including a group-buying campaign with Solar United Neighbors, have contributed to this upward trend.

The city's commitment to electrification is evident in its municipal fleet. Houston has expanded its electric vehicle fleet, operating 333 hybrid electric vehicles and 88 battery electric vehicles. An additional 107 battery electric vehicles and 41 hybrid electric vehicles are expected to be added within the next year. Charging infrastructure is also expanding, with 57 installed chargers and plans for an additional 144.

Mayor Turner's leadership in climate action has extended beyond the city's borders. The mayor led a delegation to Mexico City to launch the Resilient Cities Network initiative, Women in Resilience, highlighting Houston's role in international climate leadership. The city aksi hosted Queen Maxima of the Netherlands and signed a letter of intent with the city of Rotterdam to collaborate on community and energy resilience.

The full report tracking the initiatives' progress is available online.

Texas City ammonia plant acquired by Yara in $1.3 billion deal

Ammonia Acquisition

Yara North America, a subsidiary of Norwegian fertilizer and ammonia producer Yara International, has agreed to buy an ammonia production plant in Texas City for $1.3 billion.

The seller is GCA Holdings, an affiliate of Texas City-based chemical manufacturer Gulf Coast Ammonia, which is owned by private equity firms Lotus Infrastructure Partners and MB Energy.

The Texas City plant, with an eventual annual capacity of 1.3 million metric tons, is expected to start full production by the end of this year. Yara says the ammonia produced by the plant will serve its own fertilizer production system and its key customers.

During a recent call with analysts and investors, Magnus Ankarstrand, executive vice president and CFO of Yara International, said the plant holds the potential to become one of the company’s most profitable plants. The $1.3 billion purchase price, he added, “is a very attractive entry ticket to ammonia production in the U.S. at a very attractive cost.”

The Texas City plant will add to Yara’s holdings in the Lone Star State, as Yara is the majority owner of an ammonia, hydrogen and nitrogen production plant in Freeport.

Construction of the ammonia plant began in 2020, but technical and infrastructure issues delayed the project. On its website, Gulf Coast Ammonia says the plant represented a $600 million investment.

“Gulf Coast Ammonia is a world-class asset that required disciplined execution across development, financing, construction, and commercial structuring,” Philipp Pletka, managing director of Lotus Infrastructure Partners, says in a news release.

Trexlertown, Pennsylvania-based Air Products, which owns and operates the country’s largest hydrogen pipeline network, will continue to supply hydrogen and nitrogen for the plant under a long-term deal with Yara, according to the release.

However, the news comes two days after Yara International announced that it would no longer be purchasing ammonia assets in the Louisiana Clean Energy Complex (LCEC) from Air Products. In a separate release, Yara said it planned to reallocate funds toward "alternative mature U.S. ammonia investment opportunities with more competitive returns."

Houston hypersonic engine company lands $91M to accelerate production

Clean Speed

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were also named to the World Economic Forum's Technology Pioneers community earlier this summer.
