The fight to preserve the Inflation Reduction Act’s tax credits begins in earnest this week.

More than 100 clean energy companies, trade associations, and other industry stakeholders are descending on Capitol Hill this week to amplify an ongoing lobbying push to preserve clean energy tax credits in the upcoming budget reconciliation bill. Groups such as Clean Energy for America, the Solar Energy Industries Association, and the Carbon Capture Coalition will be making their case alongside battery storage companies like Enphase, investors from CleanCapital, utility-scale wind and solar developers, small residential solar installers, and customers that have benefited, including school superintendents.
Their mission? Convince Republicans on the House Ways and Means committee that the clean energy tax credits in the Inflation Reduction Act are key to executing President Trump’s energy agenda.
The Ways and Means Committee oversees tax writing, meaning that it will be responsible for proposing which of Trump’s tax cuts to include in the upcoming budget reconciliation bill, how to pay for them, and which of the Inflation Reduction Act’s tax credits should stay or go. “That is where these decisions are being talked about behind closed doors,” Andrew Reagan, the president of Clean Energy for America, told me.
Although the Senate will also have a say, Reagan said that the signal in Washington right now is that whatever version of the bill the House passes is going to be pretty close to the final bill. “That’s why it’s so important for any Republican members who see the benefit of what’s happening in their communities and how their constituents are saving money on energy to be talking to their colleagues right now in Ways and Means.”
I talked to Reagan more about what the lobbying push this week will look like. Our conversation has been lightly edited for length and clarity.
First off, why is this push happening now? What’s going on this week?
Folks both in clean energy businesses and in trade associations have been meeting with Hill offices on an almost daily basis throughout this year to highlight the negative impacts that would happen if these priority energy tax credits are not preserved. What’s unique here is Congress is back in session, and we have the process moving in Ways and Means. And as Speaker Johnson and others have signaled, the House version is what they expect will be the final version of a reconciliation bill. So the time to preserve these energy tax credits is now.
Which tax credits are your priority? Is it a push for everything, or is it a push for specific policies?
We want to be a voice for both the clean energy workforce and companies in this industry. The unifying message is we need policy stability, and if we’re going to achieve the energy goals that the Trump administration has laid out, we can’t do that by repealing or curtailing many of the critical energy credits. There is a lot of importance on both 45X, clean manufacturing, and 48E and 45Y, the tech neutral [clean electricity production and investment] credits because that has such a broad effect across the entire industry, across the entire economy. They are going to be pivotal to continuing to lower energy costs and create jobs.
I don’t want to give short shrift to a lot of the others that are creating innovation. I’m not sure if you saw the Jesse Jenkins study recently, but things like 30D, the consumer EV credit — he projected that has a big impact on 45X. So I think it’s also important to educate folks that there is a real risk. Even if you keep a credit in place, if you take away too much of the underlying reinforcement in related credits, you can see these really negative effects where it might be the same as effectively killing or curtailing some of those credits.
Other than making the jobs argument and the consumer savings argument, what is your message for Republicans?
One of the really important but maybe underappreciated points is that if you take away many of these credits, you will see electricity prices across the board, both for consumers and for industry, rise. There’s a study that [the Clean Energy Buyers Association] put out that gave a state by state projection of how much energy costs would rise just by next year, just if the 48E and 45Y production and investment credits were taken out. In some cases, in some states, that’s an increase of anywhere from up to 6% or 10% on top of existing inflation. So I think when we’re talking to Republican offices and Democratic offices, the case that we’re making is, “You want to lower costs for consumers? The existing tax credits that are helping more energy be produced are pivotal to doing that.”
And then, to come back to the parts of President Trump’s energy agenda that I think we all can get behind, things like bringing back manufacturing to the United States — manufacturing uses an immense amount of energy, so rising electricity prices for commercial applications make it harder to manufacture. As well as the president’s promise to lower energy bills by half in 12 to 18 months — there’s no way to achieve that goal if you curtail or drastically cut the energy tax credit.
So I think it’s important to really link for offices, if you are a Republican who wants to see President Trump’s energy agenda succeed, all of those things are reliant upon the existing energy credits. This is not a choice of, do they need to go against the president? This is something where they can still help their consumers, advance the parts of the president’s agenda that are related to energy, and they don’t have to make that choice.
Are you pushing for blanket protection for some of these tax credits? Or are you talking through potential compromises that legislators can make while still preserving the biggest benefits?
Clean Energy for America and the companies we work with, we’ve really just focused on education and the broader picture. I’ve been astounded by how many offices didn’t even know about some of the big projects in their district that were benefiting from tax credits. So I think there’s a lot more education needed about some of the very basics at this point. There are others with much more policy expertise equipped to get into some of those conversations. But again, at Clean Energy for America, our focus has been, here are all the benefits being created in your district, in your state, and backing that up with the data and the real voices of both companies and workers.
What does the fight to save the IRA on the Hill look like? Who are the main players to convince?
The first thing I would say is, the framing of “saving the IRA” — that’s not how we, or I think anyone else, thinks about it. A lot of the credits that we’re talking about predated the IRA, and so we really try to move the conversation on to, here are the pieces of these tax credits that both existed before and are currently benefiting your district. Brian Fitzpatrick on Ways and Means, he was instrumental in 2020 on some of the [investment tax credit] provisions.
We published a story this morning about the tough budget math that’s going to make it a lot harder to preserve the IRA. How is that playing into this lobbying push?
One thing I would say is, without getting too far in the weeds, I think the debate around “current policy baseline,” for how the tax package is paid for, is going to be probably the single most important thing. Even if you repealed all of the things we’re talking about, there’s no way to advance what the president wants in a tax package out of the House without a current policy baseline framework. So I think that is probably, even more so than the math of the current credits, going to be the pivotal piece of this larger policy.
Does that mean that you support a current policy baseline?
We have not advocated specifically, publicly on that issue. I’m just speaking from a process standpoint, that I would be very surprised if there’s a way that Republicans can get something out of the House if they don’t implement that current policy baseline.

Agriculture startups are suddenly some of the hottest bets in climate tech, according to the results of our Insiders Survey.
Innovations in agriculture can seem like the neglected stepchild of the climate tech world. While food and agriculture account for about a quarter of global emissions, there’s not a lot of investment in the space — or splashy breakthroughs to make the industry seem that investible in the first place. In transportation and energy, “there is a Tesla, there is an EnPhase,” Cooper Rinzler, a partner at Breakthrough Energy Ventures, told me. “Whereas in ag tech, tell me when the last IPO that was exciting was?”
That may be changing, however. Multiple participants in Heatmap’s Insiders Survey cited ag tech companies Pivot Bio and Nitricity — both of which are pursuing alternate approaches to conventional ammonia-based fertilizers — as among the most exciting climate tech companies working today.
Studies estimate that fertilizer production and use alone account for roughly 5% of global emissions. That includes emissions from the energy-intensive Haber–Bosch process, which synthesizes ammonia by combining nitrogen from the air with hydrogen at extremely high temperatures, as well as nitrous oxide released from the soil after fertilizer is applied. N2O is about 265 times more potent than carbon dioxide over a 100-year timeframe and accounts for roughly 70% of fertilizer-related emissions, as soil microbes convert excess nitrogen that crops can’t immediately absorb into nitrous oxide.
“If we don’t solve nitrous oxide, it on its own is enough of a radiative force that we can’t meet all of our goals,” Rinzler said, referring to global climate targets at large.
Enter what some consider one of the most promising agricultural innovations, perhaps since the invention of the Haber–Bosch process itself over a century ago — Pivot Bio. This startup, founded 15 years ago, engineers soil microbes to convert about 400 times more atmospheric nitrogen into ammonia than non-engineered microbe strains naturally would. “They are mini Haber–Bosch facilities, for all intents and purposes,” Pivot Bio’s CEO Chris Abbott told me, referring to the engineered microbes themselves.
The startup has now raised over $600 million in total funding and is valued at over $2 billion. And after toiling in the ag tech trenches for a decade and a half, this will be the first full year the company’s biological fertilizers — which are applied to either the soil or seed itself — will undercut the price of traditional fertilizers.
“Farmers pay 20% to 25% less for nitrogen from our product than they do for synthetic nitrogen,” Abbott told me. “Prices [for traditional fertilizers] are going up again this spring, like they did last year. So that gap is actually widening, not shrinking.”
Peer reviewed studies also show that Pivot’s treatments boost yields for corn — its flagship crop — while preliminary data indicates that the same is true forcotton, which Pivot expanded into last year. The company also makes fertilizers for wheat, sorghum, and other small grains.
Pivot is now selling these products in stores where farmers already pick up seeds and crop treatments, rather than solely through its independent network of sales representatives, making the microbes more likely to become the default option for growers. But they won’t completely replace traditional fertilizer anytime soon, as Pivot’s treatments can still meet only about 20% to 25% of a large-scale crop’s nitrogen demand, especially during the early stages of plant growth, though it’s developing products that could push that number to 50% or higher, Abbott told me.
All this could have an astronomical environmental impact if deployed successfully at scale. “From a water perspective, we use about 1/1000th the water to produce the same amount of nitrogen,” Abbott said. From an emissions perspective, replacing a ton of synthetic nitrogen fertilizer with Pivot Bio’s product prevents the equivalent of around 11 tons of carbon dioxide from entering the atmosphere. Given the quantity of Pivot’s fertilizer that has been deployed since 2022, Abbott estimates that scales to approximately 1.5 million tons of cumulative avoided CO2 equivalent.
“It’s one of the very few cases that I’ve ever come across in climate tech where you have this giant existing commodity market that’s worth more than $100 billion and you’ve found a solution that offers a cheaper product that is also higher value,” Rinzler told me. BEV led the company’s Series B round back in 2018, and has participated in its two subsequent rounds as well.
Meanwhile, Nitricity — a startup spun out of Stanford University in 2018 — is also aiming to circumvent the Haber–Bosch process and replace ammonia-based and organic animal-based fertilizers such as manure with a plant-based mixture made from air, water, almond shells, and renewable energy. The company said that its proprietary process converts nitrogen and other essential nutrients derived from combusted almond shells into nitrate — the form of nitrogen that plants can absorb. It then “brews” that into an organic liquid fertilizer that Nitricity’s CEO, Nico Pinkowski, describes as looking like a “rich rooibos tea,” capable of being applied to crops through standard irrigation systems.
For confidentiality reasons, the company was unable to provide more precise technical details regarding how it sources and converts sufficient nitrogen into a usable form via only air, water, and almond shells, given that shells don’t contain much nitrogen, and turning atmospheric nitrogen into a plant-ready form typically involves the dreaded Haber–Bosch process.
But investors have bought in, and the company is currently in the midst of construction on its first commercial-scale fertilizer factory in Central California, which is expected to begin production this year. Funding for the first-of-a-kind plant came from Trellis Climate and Elemental Impact, both of which direct philanthropic capital toward early-stage, capital-intensive climate projects. The facility will operate on 100% renewable power through a utility-run program that allows customers to opt into renewable-only electricity by purchasing renewable energy certificates,
Pinkowski told me the new plant will represent a 100‑fold increase in Nitricity’s production capacity, which currently sits at 80 tons per year from its pilot plant. “In comparison to premium conventional fertilizers, we see about a 10x reduction in emissions,” Pinkowski told me, factoring in greenhouse gases from both production and on-field use. “In comparison to the most standard organic fertilizers, we see about a 5x reduction in emissions.”
The company says trial data indicates that its fertilizer allows for more efficient nitrogen uptake, thus lowering nitrous oxide emissions and allowing farmers to cut costs by simply applying less product. According to Pinkowski, Nitricity’s current prices are at parity or slightly lower than most liquid organic fertilizers on the market. And that has farmers really excited — the new plant’s entire output is already sold through 2028.
“Being able to mitigate emissions certainly helps, but it’s not what closes the deal,” he told me. “It’s kind of like the icing on the cake.”
Initially, the startup is targeting the premium organic and sustainable agriculture market, setting it apart from Pivot Bio’s focus on large commodity staple crops. “You saw with the electrification of vehicles, there was a high value beachhead product, which was a sports car,” Pinkowski told me. “In the ag space, that opportunity is organics.”
But while big-name backers have lined up behind Pivot and Nitricity, the broader ag tech sector hasn’t been as fortunate in its friends, with funding and successful scale-up slowing for many companies working in areas such as automation, indoor farming, agricultural methane mitigation, and lab-grown meat.
Everyone’s got their theories for why this could be, with Lara Pierpoint of Trellis telling me that part of the issue is “the way the federal government is structured around this work.” The Department of Agriculture allocates relatively few resources to technological innovation compared to the Department of Energy, which in turn does little to support agricultural work outside of its energy-specific mandate. That ends up meaning that, as Pierpoint put it, ”this set of activities sort of falls through the cracks” of the government funding options, leaving agricultural communities and companies alike struggling to find federal programs and grant opportunities.
“There’s also a mismatch between farmers and the culture of farming and agriculture in the United States, and just even geographically where the innovation ecosystems are,” Emily Lewis O’Brien, a principal at Trellis who led the team’s investment in Nitricity, told me of the social and regional divides between entrepreneurs, tech investors and rural growers. “Bridging that gap has been a little bit tricky.”
Still, investors remain optimistic that one big win will help kick the money machines into motion, and with Pivot Bio and Nitricity, there are finally some real contenders poised to transform the sector. “We’re going to wake up one day and someone’s going to go, holy shit, that was fast,” Abbott told me. “And it’s like, well you should have been here for the decade of hard work before. It’s always fast at the end.”
The most popular scope 3 models assume an entirely American supply chain. That doesn’t square with reality.
“You can’t manage what you don’t measure,” the adage goes. But despite valiant efforts by companies to measure their supply chain emissions, the majority are missing a big part of the picture.
Widely used models for estimating supply chain emissions simplify the process by assuming that companies source all of their goods from a single country or region. This is obviously not how the world works, and manufacturing in the United States is often cleaner than in countries with coal-heavy grids, like China, where many of the world’s manufactured goods actually come from. A study published in the journal Nature Communications this week found that companies using a U.S.-centric model may be undercounting their emissions by as much as 10%.
“We find very large differences in not only the magnitude of the upstream carbon footprint for a given business, but the hot spots, like where there are more or less emissions happening, and thus where a company would want to gather better data and focus on reducing,” said Steven Davis, a professor of Earth system science in the Stanford Doerr School of Sustainability and lead author of the paper.
Several of the authors of the paper, including Davis, are affiliated with the software startup Watershed, which helps companies measure and reduce their emissions. Watershed already encourages its clients to use its own proprietary multi-region model, but the company is now working with Stanford and the consulting firm ERG to build a new and improved tool called Cornerstone that will be freely available for anyone to use.
“Our hope is that with the release of scientific papers like this one and with the launch of Cornerstone, we can help the ecosystem transition to higher quality open access datasets,” Yohanna Maldonado, Watershed’s Head of Climate Data told me in an email.
The study arrives as the Greenhouse Gas Protocol, a nonprofit that publishes carbon accounting standards that most companies voluntarily abide by, is in the process of revising its guidance for calculating “scope 3” emissions. Scope 3 encompasses the carbon that a company is indirectly responsible for, such as from its supply chain and from the use of its products by customers. Watershed is advocating that the new standard recommend companies use a multi-region modeling approach, whether Watershed’s or someone else’s.
Davis walked me through a hypothetical example to illustrate how these models work in practice. Imagine a company that manufactures exercise bikes — it assembles the final product in a factory in the U.S., but sources screws and other components from China. The typical way this company would estimate the carbon footprint of its supply chain would be to use a dataset published by the U.S. Environmental Protection Agency that estimates the average emissions per dollar of output for about 400 sectors of the U.S. economy. The EPA data doesn’t get down to the level of detail of a specific screw, but it does provide an estimate of emissions per dollar of output for, say, hardware manufacturing. The company would then multiply the amount of money it spent on screws by that emissions factor.
Companies take this approach because real measurements of supply chain emissions are rare. It’s not yet common practice for suppliers to provide this information, and supply chains are so complex that a product might pass through several different hands before reaching the company trying to do the calculation. There are emerging efforts to use remote sensing and other digital data collection and monitoring systems to create more accurate, granular datasets, Alexia Kelly, a veteran corporate sustainability executive and current director at the High Tide Foundation, told me. In the meantime, even though sector-level emissions estimates are rough approximations, they can at least give a company an indication of which parts of their supply chain are most problematic.
When those estimates don’t take into account country of origin, however, they don’t give companies an accurate picture of which parts of their supply chains need the most attention.
The new study used Watershed’s multi-region model to look at how different types of companies’ emissions would change if they used supply chain data that better reflected the global nature of supply chains. Davis is the first to admit that the study’s findings of higher emissions are not surprising. The carbon accounting field has long been aware of the shortcomings of single-region models. There hasn’t been a big push to change that, however, because the exercise is already voluntary and taking into account global supply chains is significantly more difficult. Many countries don’t publish emissions and economic data, and those that do use a variety of methods to report it. Reconciling those differences adds to the challenge.
While the overall conclusion isn’t surprising, the study may be the first to show the magnitude of the problem and illustrate how more accurate modeling could redirect corporate sustainability efforts. “As far as I know, there is no similar analysis like this focused on corporate value chain emissions,” Derik Broekhoff, a senior scientist at the Stockholm Environment Institute, told me in an email. “The research is an important reminder for companies (and standard setters like the Greenhouse Gas Protocol), who in practice appear to be overlooking foreign supply chain emissions in large numbers.”
Broekhoff said Watershed’s upcoming open-source model “could provide a really useful solution.” At the same time, he said, it’s worth noting that this whole approach of calculating emissions based on dollars spent is subject to significant uncertainty. “Using spending data to estimate supply chain emissions provides only a first-order approximation at best!”
The decision marks the Trump administration’s second offshore wind defeat this week.
A federal court has lifted Trump’s stop work order on the Empire Wind offshore wind project, the second defeat in court this week for the president as he struggles to stall turbines off the East Coast.
In a brief order read in court Thursday morning, District Judge Carl Nichols — a Trump appointee — sided with Equinor, the Norwegian energy developer building Empire Wind off the coast of New York, granting its request to lift a stop work order issued by the Interior Department just before Christmas.
Interior had cited classified national security concerns to justify a work stoppage. Now, for the second time this week, a court has ruled the risks alleged by the Trump administration are insufficient to halt an already-permitted project midway through construction.
Anti-offshore wind activists are imploring the Trump administration to appeal this week’s injunctions on the stop work orders. “We are urging Secretary Burgum and the Department of Interior to immediately appeal this week’s adverse federal district court rulings and seek an order halting all work pending appellate review,” Robin Shaffer, president of Protect Our Coast New Jersey, said in a statement texted to me after the ruling came down.
Any additional delays may be fatal for some of the offshore wind projects affected by Trump’s stop work orders, irrespective of the rulings in an appeal. Both Equinor and Orsted, developer of the Revolution Wind project, argued for their preliminary injunctions because even days of delay would potentially jeopardize access to vessels necessary for construction. Equinor even told the court that if the stop work order wasn’t lifted by Friday — that is, January 16 — it would cancel Empire Wind. Though Equinor won today, it is nowhere near out of the woods.
More court action is coming: Dominion will present arguments on Friday in federal court against the stop work order halting construction of its Coastal Virginia offshore wind project.
