3 takeaways from COP28 from Houston biotech, sustainability founder

Before he even had a chance to recover from the jetlag, Moji Karimi was thinking about his biggest takeaways from 2023 United Nations Climate Change Conference or Conference of the Parties, more commonly known as COP28.

Karimi, CEO and co-founder of Cemvita, a biotech company with sustainable solutions for the energy transition, joined the Houston Innovators Podcast this week to discuss what his biggest takeaways were.

"It was a pretty amazing experience," Karimi says, comparing the event to how CERAWeek has evolved to really have a strong presence in its innovation-focused track called Agora. "This year you had a massive section for innovation and sustainability. I think that will become a theme in COP29 and beyond to bring entrepreneurs, investors, and more participating in the event."

Karimi's three big observations are outlined below, as is the full podcast with him sharing more about Cemvita's growth this year.


Expanding the environmental footprint

One of the big things Karimi observed was that there seems to be a rising conversation about not only how carbon emissions are effecting climate change, but that companies and countries need to look more broadly at their environmental impacts.

Specifically, Karimi learned about the new framework Task Force on Nature-Related Financial Disclosures (TNFD), an addition to Task Force on Climate-Related Financial Disclosures (TCFD), which was introduced a few years back.

"TNFD is the new framework to capture non-carbon emissions-related aspects of an impact on the environment, such as biodiversity loss," he says.

Language has evolved to reflect this shift too, Karimi says, referencing "nature-positive tech" and "nature tech." He says he feels like Europe has led the way so far, but in the next year or two the conversations will come to the United States.

"Some of this is driven by COP30 being in Brazil and being focused on biodiversity," he adds.

A major focus on nuclear

Karimi says he saw a lot of support for nuclear energy, which can lower the cost and carbon intensity of power. Personally, Karimi is wondering what happens if and win nuclear is better adapted, solving the current challenges the power industries face.

"What I'm interested in is so many other climate tech applications that are enabled once you have low-cost, and low-carbon power from nuclear energy. That will be interesting to watch," he says.

Actionism, not activism

Lastly, Karimi says he saw a huge push toward action, not simply advocacy. The emphasis on "actionism" included activations for COP28 attendees to share what actions could be taken now.

"The point was to all come together, no matter where you come from, and focus on what actions you can take," he says. "It was interesting to bring people together in a different way. We'll see how that translates into actions from here on."

Sage Geosystems, a Houston-based developer of geothermal power systems, has chosen a site in Nevada for its commercial-scale Project Vector facility.

The company’s two-well enhanced geothermal system (EGS) will deliver around-the-clock geothermal heat to Ormat Technologies’ Blue Mountain geothermal power plant in Winnemucca, Nevada.

The startup expects to begin drilling the first well later this year, with the first electricity to be generated in 2027 and full-scale production to start in 2028.

In the Nevada system, fluid will circulate through an engineered subsurface reservoir, absorb heat from the surrounding rock and return heat to the surface. The heat will be delivered to the Blue Mountain plant for conversion into electricity.

Project Vector builds on the performance of Sage’s SMECI facility in South Texas. That facility’s results, combined with Sage’s digital twin platform, will be used to shape to the design and development of Project Vector.

Project Vector supports Sage’s growing commercial pipeline, including a 150-megawatt geothermal power agreement with Meta Platforms, the parent company of Facebook and Instagram.

“Blue Mountain is an ideal location for Sage to take the next step in continuing to commercialize our proprietary EGS approach,” Jason Peart, chief operating officer at Sage, said in a release. “By delivering geothermal heat into an existing power plant, Project Vector can demonstrate the model for bringing firm, 24/7 geothermal power to market at scale.”

Project Vector extends Sage’s relationship with Ormat.

In August 2025, Sage and Ormat agreed to accelerate commercialization of Sage’s geothermal technology at an Ormat power plant. This January, Ormat co-led Sage’s $97 million Series B funding round.

Sage, founded in 2020, has raised about $159 million across three funding rounds.

As the startup ramps up its ESG platform, Sage is targeting data centers as customers, among other large-scale users of electricity.

“The energy needs are huge, and they need it now,” CEO Cindy Taff said on Data Center Frontiers’ podcast. “They can’t depend on the grid anymore.”
