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.

Houston-based ENGIE to add new wind and solar projects to Texas grid

coming soon

Houston-based ENGIE North America Inc. has expanded its partnership with Los Angeles-based Ares Infrastructure Opportunities to add 730 megawatts of renewable energy projects to the ERCOT grid.

The new projects will include one wind and two solar projects in Texas.

“The continued growth of our relationship with Ares reflects the strength of ENGIE’s portfolio of assets and our track record of delivering, operating and financing growth in the U.S. despite challenging circumstances,” Dave Carroll, CEO and Chief Renewables Officer of ENGIE North America, said in a news release. “The addition of another 730 MW of generation to our existing relationship reflects the commitment both ENGIE and Ares have to meeting growing demand for power in the U.S. and our willingness to invest in meeting those needs.”

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada, and 52.7 gigawatts worldwide. The company is targeting 95 gigawatts by 2030.

ENGIE launched three new community solar farms in Illinois since December, including the 2.5-megawatt Harmony community solar farm in Lena and the Knox 2A and Knox 2B projects in Galesburg.

The company's 600-megawatt Swenson Ranch Solar project near Abilene, Texas, is expected to go online in 2027 and will provide power for Meta, the parent company of social media platform Facebook. Late last year, ENGIE also signed a nine-year renewable energy supply agreement with AstraZeneca to support the pharmaceutical company’s manufacturing operations from its 114-megawatt Tyson Nick Solar Project in Lamar County, Texas.

Houston geothermal company raises $97M Series B

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.
