Turns out — Texas might not be as green as you thought.
A new report from WalletHub looked at 25 key metrics — from green buildings per capita to energy consumption from renewable resources — to evaluate the current health of states' environment and residents’ environmental-friendliness. Texas ranked No. 38, meaning it was the thirteenth least green state, only scoring 50.40 points out of 100.
“It’s important for every American to do their part to support greener living and protect our environment. However, it’s much easier being green in some states than others," writes Cassandra Happe, a WalletHub Analyst, in the report. "For example, if a state doesn’t have a great infrastructure for alternative-fuel vehicles, it becomes much harder for residents to adopt that technology. Living in a green state is also very beneficial for the health of you and your family, as you benefit from better air, soil and water quality.”
Here's how Texas ranked among a few of the key metrics:
No. 35 for air quality
No. 38 for soil quality
No. 38 for water quality
No. 26 for LEED-certified buildings per capita
No. 32 for percent of renewable energy consumption
No. 45 for energy consumption per capita
No. 38 for gasoline consumption (in gallons) per capita
Despite Texas' solar energy generation surpassed the output by coal last month, according to a report from the Institute For Energy Economics and Financial Analysis, the Lone Star State has room for improvement.
California was ranked as the greenest state, with Vermont, New York, Maryland, and Washington, respectively, rounding out the top five. The country's least green state is West Virginia, followed by Louisiana, Alabama, Mississippi, and Kentucky.
The report also zeroed in on how politics play into a state's climate system. Democrat-led states ranked around No. 15 on average, whereas Republican states fell at around No. 36.
For the first time in Texas, according to a recent report, solar energy generation surpassed the output by coal.
The report — from the Institute For Energy Economics and Financial Analysis — sourced the Energy Information Administration’s hourly grid monitor for March 2024. This shift in a predominantly oil and gas dominated history of Texas energy output, was due to solar power’s 3.26 million megawatt-hours to Electric Reliability Council of Texas (ERCOT) grid, compared to coal’s 2.96 million MWh.
In addition, coal’s market share fell below 10 percent to 9 percent for the first time ever, to just over 9 percent. The increase in solar energy pushed solar’s share of ERCOT generation to more than 10 percent for the month, which was also a first.
Due to its sheer size, Texas is the No.1 state for solar capacity. According to the report from SmartAsset, the Lone Star State has the most clean energy capacity at 56,405 megawatts, but continues to trail states with similar geographic characteristics in overall clean energy prevalence.
Texas only 38 percent of the state’s electricity capacity comes from clean electricity, and it has the second-largest solar capacity, which means Texas has the most means, space, and potential to accommodate cleaner electricity. Texas as a whole, ranked No. 22 on the list for states with the most clean energy in the SmartAsset report.
In Texas, generation in March 2024 was 1.17 million MWh more year-over-year, which is a 56 percent increase. ERCOT data shows that the system currently has 22,710 megawatts (MW) of operational solar capacity according to IEEFA, and is expected to expand by almost one-third by the end of 2024 with an additional 7,168 MW of capacity added. The number just considers Texas solar projects that have set aside the financing required to get onto the ERCOT grid and that have a signed interconnection agreement.
Texas burned 50.7 million tons of coal for electricity, which was 13 percent of the U.S. total in 2023 according to the EIA grid monitor. Coal's annual share of ERCOT demand ranged from 36 percent to 40 percent from 2003 through 2014. The last year percent. In 2020, coal was under 20 percent in 2020; and was less than 15 percent in 2023 supplying just 13.9 percent of the system’s total demand.
The IEEFA notes coal’s low March production is important because in recent years it has been the moderate temperatures of April and May and steady winds that have affected the usage and the market share.
There’s a reason “carbon footprint” became a buzzword. It sounds like something we should know. Something we should measure. Something that should be printed next to the calorie count on a label.
But unlike calories, a carbon footprint isn’t universal, standardized, or easy to calculate. In fact, for most companies—especially in energy and heavy industry—it’s still a black box.
That’s the problem Planckton Data is solving.
On this episode of the Energy Tech Startups Podcast, Planckton Data co-founders Robin Goswami and Sandeep Roy sit down to explain how they’re turning complex, inconsistent, and often incomplete emissions data into usable insight. Not for PR. Not for green washing. For real operational and regulatory decisions.
And they’re doing it in a way that turns sustainability from a compliance burden into a competitive advantage.
From calories to carbon: The label analogy that actually works
If you’ve ever picked up two snack bars and compared their calorie counts, you’ve made a decision based on transparency. Robin and Sandeep want that same kind of clarity for industrial products.
Whether it’s a shampoo bottle, a plastic feedstock, or a specialty chemical—there’s now consumer and regulatory pressure to know exactly how sustainable a product is. And to report it.
But that’s where the simplicity ends.
Because unlike food labels, carbon labels can’t be standardized across a single factory. They depend on where and how a product was made, what inputs were used, how far it traveled, and what method was used to calculate the data.
Even two otherwise identical chemicals—one sourced from a refinery in Texas and the other in Europe—can carry very different carbon footprints, depending on logistics, local emission factors, and energy sources.
Planckton’s solution is built to handle exactly this level of complexity.
AI that doesn’t just analyze
For most companies, supply chain emissions data is scattered, outdated, and full of gaps.
That’s where Planckton’s use of AI becomes transformative.
It standardizes data from multiple suppliers, geographies, and formats.
It uses probabilistic models to fill in the blanks when suppliers don’t provide details.
It applies industry-specific product category rules (PCRs) and aligns them with evolving global frameworks like ISO standards and GHG Protocol.
It helps companies model decarbonization pathways, not just calculate baselines.
This isn’t generative AI for show. It’s applied machine learning with a purpose: helping large industrial players move from reporting to real action.
And it’s not a side tool. For many of Planckton’s clients, it’s becoming the foundation of their sustainability strategy.
From boardrooms to smokestacks: Where the pressure is coming from
Planckton isn’t just chasing early adopters. They’re helping midstream and upstream industrial suppliers respond to pressure coming from two directions:
Downstream consumer brands—especially in cosmetics, retail, and CPG—are demanding footprint data from every input supplier.
Upstream regulations—especially in Europe—are introducing reporting requirements, carbon taxes, and supply chain disclosure laws.
The team gave a real-world example: a shampoo brand wants to differentiate based on lower emissions. That pressure flows up the value chain to the chemical suppliers. Who, in turn, must track data back to their own suppliers.
It’s a game of carbon traceability—and Planckton helps make it possible.
Why Planckton focused on chemicals first
With backgrounds at Infosys and McKinsey, Robin and Sandeep know how to navigate large-scale digital transformations. They also know that industry specificity matters—especially in sustainability.
So they chose to focus first on the chemicals sector—a space where:
Supply chains are complex and often opaque.
Product formulations are sensitive.
And pressure from cosmetics, packaging, and consumer brands is pushing for measurable, auditable impact data.
It’s a wedge into other verticals like energy, plastics, fertilizers, and industrial manufacturing—but one that’s already showing results.
Carbon accounting needs a financial system
What makes this conversation unique isn’t just the product. It’s the co-founders’ view of the ecosystem.
They see a world where sustainability reporting becomes as robust as financial reporting. Where every company knows its Scope 1, 2, and 3 emissions the way it knows revenue, gross margin, and EBITDA.
But that world doesn’t exist yet. The data infrastructure isn’t there. The standards are still in flux. And the tooling—until recently—was clunky, manual, and impossible to scale.
Planckton is building that infrastructure—starting with the industries that need it most.
Houston as a launchpad (not just a legacy hub)
Though Planckton has global ambitions, its roots in Houston matter.
The city’s legacy in energy and chemicals gives it a unique edge in understanding real-world industrial challenges. And the growing ecosystem around energy transition—investors, incubators, and founders—is helping companies like Planckton move fast.
“We thought we’d have to move to San Francisco,” Robin shares. “But the resources we needed were already here—just waiting to be activated.”
The future of sustainability is measurable—and monetizable
The takeaway from this episode is clear: measuring your carbon footprint isn’t just good PR—it’s increasingly tied to market access, regulatory approval, and bottom-line efficiency.
And the companies that embrace this shift now—using platforms like Planckton—won’t just stay compliant. They’ll gain a competitive edge.

Houston climatech company Gold H2 completed its first field trial that demonstrates subsurface bio-stimulated hydrogen production, which leverages microbiology and existing infrastructure to produce clean hydrogen.
“When we compare our tech to the rest of the stack, I think we blow the competition out of the water," Prabhdeep Singh Sekhon, CEO of Gold H2 Sekhon previously told Energy Capital.
The project represented the first-of-its-kind application of Gold H2’s proprietary biotechnology, which generates hydrogen from depleted oil reservoirs, eliminating the need for new drilling, electrolysis or energy-intensive surface facilities. The Woodlands-based ChampionX LLC served as the oilfield services provider, and the trial was conducted in an oilfield in California’s San Joaquin Basin.
According to the company, Gold H2’s technology could yield up to 250 billion kilograms of low-carbon hydrogen, which is estimated to provide enough clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent.
“This field trial is tangible proof. We’ve taken a climate liability and turned it into a scalable, low-cost hydrogen solution,” Sekhon said in a news release. “It’s a new blueprint for decarbonization, built for speed, affordability, and global impact.”
Highlights of the trial include:
First-ever demonstration of biologically stimulated hydrogen generation at commercial field scale with unprecedented results of 40 percent H2 in the gas stream.
Demonstrated how end-of-life oilfield liabilities can be repurposed into hydrogen-producing assets.
The trial achieved 400,000 ppm of hydrogen in produced gases, which, according to the company,y is an “unprecedented concentration for a huff-and-puff style operation and a strong indicator of just how robust the process can perform under real-world conditions.”
The field trial marked readiness for commercial deployment with targeted hydrogen production costs below $0.50/kg.
“This breakthrough isn’t just a step forward, it’s a leap toward climate impact at scale,” Jillian Evanko, CEO and president at Chart Industries Inc., Gold H2 investor and advisor, added in the release. “By turning depleted oil fields into clean hydrogen generators, Gold H2 has provided a roadmap to produce low-cost, low-carbon energy using the very infrastructure that powered the last century. This changes the game for how the world can decarbonize heavy industry, power grids, and economies, faster and more affordably than we ever thought possible.”
