ESG has certainly come a long way, but has it come too far, actually? Photo via Getty Images

Whose responsibility is it to care for the social good? That’s an important, yet hopelessly complex question, particularly when aimed at sustainability.

When it comes to businesses and other profit-seeking firms, they tend to search for a balance between success today and success overtime. Too much focus in either direction can be deadly.

An apt analogy is a virus: too much reproduction too fast and the host dies, which is why the most successful viruses find the threshold for maximizing reproduction without overly weakening the host.

Payment is about to be due, but from whom?

The ESG movement encapsulates targets from ethical investing related to environmental issues, social values and corporate governance. As it relates to climate, people are working hard to determine how much cumulative effect of human activity is too much for our survival. And there continues to be open questions about how businesses should react to the scientific consensus that climate conditions will continue getting worse, without immediate and severe corrective action. If the consensus is that this is a problem for businesses to fix, whose money do they spend to do it?

Greed was good, once

Nobel-winning economist Milton Friedman famously advocated for firms to focus primarily on returning value to shareholders. With respect to social good, he advocated that shareholders use their returns to pursue them; businesses should just chase profit. His 1970 article in the New York Times Magazine is worth a read, particularly his last paragraph, where he observes that corporate dollars spent advancing social responsibility represent the theft of money from investors, customers, or employees. The challenge is, how many negative externalities do we absorb before seeking to redirect corporate profits?

Making impact be part of the analysis

Others have argued that firms have a social responsibility and should pursue, using the term John Elkington coined in 1994, a triple bottom line approach, focusing on profit, people, and planet. Adherents to this approach believe you only get what you measure, and therefore,businesses should measure more than just profit. The challenge is, who is smart enough to balance these accounts?

ESG to the rescue?

The term ESG itself was the result of good intentioned actors in the investment space who wanted to track the efficacy of investing in businesses that scored well for social responsibility. They theorized, and had some support, that these companies outperformed the market. The result was the formation of the Principles for Responsible Investment in 2013, with its six core principles for “incorporating ESG issues into investment practice.”

ESG has certainly come a long way from Milton Friendmen, though it’s challenging to say how the movement is going. From one perspective, it looks like everyone is in trouble. Banks for investing in companies who are not moving fast enough. Energy companies and other producers of consumer products for greenwashing their efforts. Private equity firms for forcing ESG standards that some view as a step-too-far. Financial service companies for assisting in greenwashing. And, of course, the worst offenders are “the woke.” From the other perspective, we are finally starting to see some incentives for companies to address and solve long-ignored problems.

One size fits no one

The question of “Who is responsible for ESG?” reminds me of a presentation I attended in spring 2022, given by a senior executive of a large landfill operator. Before he began his discussion of the environmental impacts of operating a landfill, he noted that his billion dollar company did not really create any trash, it simply collected and received trash from all of us! He was begging the question, “Am I solely responsible for your bad decisions?”

And that’s really the issue with ESG, is it not? Who, for example, is responsible for creating pollution? The energy companies for producing oil and natural gas from underground reserves, or the members of the public who drive cars, buy plastic goods, and flip on the lights? The government for letting those things happen? The answer is sadly both none of us and all of us.

Regulators, mount up

Regulating and investing are often in conflict, but they share one common characteristic: few people have ever done either well. That doesn’t mean we quit trying. There are those among us who can find the signal in the noise, who can stare at a pile of numbers and find the rule that answers the question, or at least correlates well to the desired outcome.

People change expensive behaviors

Charlie Munger famously said, “Show me the incentive, and I’ll show you the outcome.” If I had a magic wand, I would want the power to create global markets for the right to release harmful pollutants / emissions or deposit certain types of waste in landfills. It has worked before, and it will likely be what leads us where we need to go. Until we create marketplaces limiting the release of pollutants and disposal of waste, society will continue to fall prey to complex regulatory solutions that are easy for incumbent industries to strike down. Instead, putting a price on these activities will allow the incumbents to innovate and new companies to compete.

When it comes to ESG, I think we fear two outcomes equally: a world that feels a little out of control and a class of people, or institutions of government, who appear all too confident they have the answers. Maybe we can turn the heat down in the ESG debate by prioritizing what we measure and report and creating marketplaces that incentivize people to solve the most pressing problems.

Greening the bottom line: Houston expert on the ups and downs of sustainability transformation, reporting

guest column

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."
