Amid remarkable fund allocation towards tackling environmental, social, and corporate governance issues, investors deeply concerned about climate change exert substantial leverage on firms and regulators to make reforms.

Furthermore, the Securities and Exchange Commission has proposed new rules requiring all publicly listed corporations to disclose climate change risks in their regular filings with clear reporting obligations, such as information on direct greenhouse gas emissions (Scope 1), indirect emissions from purchased electricity or other forms of energy (Scope 2), as well as GHG emissions from upstream and downstream activities in the value chain (Scope 3).

Although sustainability has invariably moved to the top of the corporate agenda across various sectors, businesses still face challenges in effectively implementing these transformative changes. Many companies are still dealing with questions like:

  • What problems and possibilities should they prioritize?
  • Where should they devote time, effort, and money to have the most long term effect via business processes?
  • What principles, policies, and internal standards should be implemented to initiate the process and get good ESG ratings?
  • When do corporate sustainability challenges necessitate collaborations with other businesses to meet commitments and achieve goals?
  • What organizational behavior and change management measures should be incorporated to induce sustainability into the corporate culture?

One-fifth of businesses still need a sustainability plan in place, and fewer than 30 percent feel the effect of that strategy is evident to all employees.

Introducing climate-related practices across businesses and corporations takes time and effort. Since sustainability transformation initiatives span multiple business functions and units, whether they are helping or hurting the bottom line is often a fuzzy picture. It is not easy to quantify near-term profitable impacts directly emanating from sustainable strategies, disincentivizing many businesses from setting ambitious carbon reduction targets.

Businesses often struggle with what they intend to assess and what "good enough" performance looks like for the firm. Furthermore, sustainability performance reporting is infested with the inherent stakes of the legitimacy of data collection, defining the metrics and materiality, accountability to the stakeholders, the dynamism of the business environment, the complexity of reporting standards, and the risk of obsolescence of the tool.

For context, there are approximately 600 sustainability reporting standards, industry efforts, frameworks, and recommendations worldwide. Additionally, the one-directional data collection method used by the carbon market trading systems for scoring analyses often leads to intentional or unintentional greenwashing.

So then, what is the path forward?

An effective strategy would involve adopting a synergistic approach, just like the yin and the yang elements that embody balance and harmony on two distinct yet interconnected levels. The yin aspect, prevailing at the government level, would require a robust standardization of reporting frameworks via policymaking and regulations that can effectively implement suitable transformation engines for businesses. It will entail developing adaptable market mechanisms to successfully guide businesses and consumers to identify, plan, navigate, strategize, and execute greenhouse gas reduction initiatives. It will require answers to foundational questions like:

  • What tools and resources can help businesses improve their financial performance by reducing energy waste and energy costs?
  • How do manufacturers engage their suppliers in low-cost technical reviews to improve process lines, use materials more efficiently, and reduce waste?
  • How can waste management and recycling help a business by saving money, energy, and natural resources?

There is a dire need to standardize and consolidate the industry benchmarks and reporting frameworks against which businesses can assess their performance for climate action and potentially improve their bottom line by investing in appropriate carbon mitigation activities. This will create a fundamental shift in the mindset of corporates and raise the level of conversation from "Should we implement sustainable business frameworks?" to "How we could best implement sustainable frameworks for better ROI and an impactful bottom line?"

On the other hand, the yang element operates at the business or corporation level. Successful execution of sustainability strategies entails interweaving the sustainability thread into the business core across strategies and processes, operations and personnel, and products and services.

What is the business case for sustainability efforts? From operational cost savings to expansion in new markets, from enhanced brand equity to investor interest and share expansion, companies that incorporate robust and scalable sustainable practices have opportunities to unlock new sources of value capture and new markets that can deliver immediate financial rewards. Such measures will demonstrate the overall sustainability transformation's power and potentially provide money or cost savings to fund other components.

One way to do it is by introducing circular business models to reshape the whole product usage cycle: re-engineering product designs with more sustainable materials, redesigning the manufacturing lifecycle, recycling products, packaging, and waste, and reducing emissions in transportation, water, and energy consumption activities. By leveraging technology and AI in the extended system of interactions within and outside the business, companies can monitor, predict, and reduce the carbon emissions in their supply chains and yield immediate financial results.

Designing, implementing, and managing the foundational governance of sustainable business practices, strategies, structure, and tactics will require robust governance of sustainability efforts in all key business areas, including marketing, sales, product development, and finance. Additionally, organizational values, leadership initiative from the CEO and board level to the employees, and stakeholder interest are necessary to drive value for business policy. Involving employees in decision-making will help induce better commitment and accountability to implementing economic, social, environmental, and technologically sustainable interventions and initiatives.

Finally, businesses need to understand that they could truly develop long-term business success and shareholder value when they stop viewing sustainability from a compliance or ESG reporting lens. Long-term business success cannot be achieved solely by maximizing short-term profits but through market-oriented yet responsible behavior that automatically drives enhanced business bottom lines. This demands a collaborative partnership between policymakers, the private sector, nonprofit organizations, academia, and civic society to usher in economic growth, competitiveness, and consumer interest. This partnership is essential for environmental protection and social responsibility to ensure a sustainable future.

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.

Houston maritime startup raises $43M to electrify cargo vessels

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."
