New research reveals the U.S. has a plausible but narrow path to accomplishing its international climate commitments.
Here’s the good news: The United States is closer than it’s ever been to reaching its ambitious Paris Agreement goals. For the first time since President Joe Biden set a new and aggressive carbon-reduction target in 2021 — and for the first time, arguably, since the climate accord was signed in 2016 — America has a plausible path to accomplishing its international climate commitments.
Here’s the bad: The country still needs a few more big policies to get over the line. Cities, states, companies, and the federal government must slash carbon pollution in ways that go beyond what the Inflation Reduction Act, Biden’s signature climate law, will achieve. Even then, emissions must plunge more than twice as fast over the next seven years as they did over the past 17.
Those are the headline findings of a new report from the Rhodium Group, a California-based energy-research firm that produces independent analyses of American climate policy.
The report finds that in order to make its 2030 goal, the U.S. needs to cut emissions about 40% faster than current estimates project. That is doable, but it will require a broad societal effort, Ben King, an author of the report and an associate director at the Rhodium Group, told me. Rhodium dubs this playbook the “joint action” scenario.
“It’s totally appropriate to look at it and say [the Paris goals] are within reach,” he said. “But being within reach doesn’t mean it’s an easy reach.”
Those policies will not be easy to pass, although according to King, they should make economic sense: The policies and actions necessary to make the Paris goal should help American households somewhere on the order of $290 to $350 a year.
The high, mid, low ranges reflect uncertainty around future fossil fuel prices, economic growth, and clean-energy technology costs.The Rhodium Group
Under the Paris Agreement, the U.S. has committed to reducing its annual emissions 50 to 52% by 2030, as compared to the all-time high that they reached in 2005. For reference, American emissions were about 15.5% below their all-time high last year, according to an early estimate. So the country obviously has a long way to go.
Some emissions cuts are already baked in, however. Thanks to the Inflation Reduction Act, or IRA, America is on track to get its emissions about 40% below their all-time high by 2030, the report says. (There’s some uncertainty here: If fossil-fuel prices spike and the IRA is more successful than hoped, American emissions could fall as much as 42% below their all-time high; if fossil-fuel prices crash, renewable prices spike, and the IRA founders, then emissions may only fall 32% of the way below their all-time high.) So in order to make its Paris goal, the country must find an extra 10 percentage points of emissions cuts — and it must do so quickly enough to make a difference eight years from now.
So what will that require? Consider this a check list to making America’s Paris Agreement goals:
First, the Environmental Protection Administration must adopt a robust set of anti-pollution rules across several parts of the economy, King said. It must use the Clean Air Act to pass stringent new limits on how much greenhouse-gas pollution that power plants can pump into the atmosphere — and it must tighten existing rules on conventional air pollution, including toxic airborne mercury and smog that crosses state lines. The EPA also has to finalize its rules on methane pollution from oil and gas facilities, and it has to strengthen its rules for tailpipe pollution from cars and trucks so that they run to 2030.
Other federal agencies must take new actions, too. The Department of Energy needs to strengthen its energy-efficiency standards, which apply to home appliances, building equipment, and industrial machinery, King said. And the Department of Agriculture must finish setting up a program that pays farmers and foresters to use climate-smart practices.
These executive actions must then survive judicial scrutiny and remain on the books until 2030, enduring a change of presidential administration in 2024 or 2028. How likely is that? Not as improbable as you might think. Many of the rules, including the Energy Department standards and most of the EPA’s regulation, clearly falls within their respective agency’s authority, and Congress has already funded the program for climate-smart farming. But some rules, particularly the EPA’s greenhouse-gas rules for power plants, could test the conservative Supreme Court’s limits. Last year, that court struck down the EPA’s attempt to establish a carbon cap-and-trade scheme under the Clean Air Act; the justices also claimed the right to strike down any executive action that raises a “major” political question. But that ruling didn’t forbid the EPA from everissuing carbon-related regulations, and the agency could publish a new and much simpler rule that will accomplish the same carbon cuts at greater cost.
Yet even an aggressive suite of federal rules won’t be enough to achieve the country’s 2030 goal, the report found. When layered on top of the IRA, those federal programs will get the country’s emissions only about 46% below their all-time high. The country still needs to find another four to six percentage points of emissions cuts in order to lock in Paris.
So states must step up. About 20 states belong to the U.S. Climate Alliance, a pact of largely Democratic governors who committed to meeting the Paris Agreement goals. Those states must adopt “best-in-class policies,” King said, including clean-energy standards, zero-emissions targets, and low-carbon fuel standards. They must fund and grow their public-transit systems. But even that won’t be enough. In order for the U.S. to meet its goals, every utility with a clean-electricity pledge in 2030 or 2050 must have either achieved its goal or be well on its way to doing so.
If all that happens — and fossil-fuel prices don’t collapse, solar-panel and wind-turbine prices don’t spike, and the IRA isn’t rendered ineffectual or repealed outright — then the U.S. could barely make its 2030 Paris goals.
This litany of policies might seem far-fetched, but remember: The IRA, which will take America most of the way to meeting its 2030 goal, itself once seemed impossible. Finishing that journey will require many smaller impossibilities. But such is the work when the prize — a wealthy economy that is well on its way to total decarbonization — is so sweet.

Rob and Jesse talk with John Henry Harris, the cofounder and CEO of Harbinger Motors.
You might not think that often about medium-duty trucks, but they’re all around you: ambulances, UPS and FedEx delivery trucks, school buses. And although they make up a relatively small share of vehicles on the road, they generate an outsized amount of carbon pollution. They’re also a surprisingly ripe target for electrification, because so many medium-duty trucks drive fewer than 150 miles a day.
On this week’s episode of Shift Key, Rob and Jesse talk with John Henry Harris, the cofounder and CEO of Harbinger Motors. Harbinger is a Los Angeles-based startup that sells electric and hybrid chassis for medium-duty vehicles, such as delivery vans, moving trucks, and ambulances.
Rob, John, and Jesse chat about why medium-duty trucking is unlike any other vehicle segment, how to design an electric truck to last 20 years, and how President Trump’s tariffs are already stalling out manufacturing firms. Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Here is an excerpt from our conversation:
Robinson Meyer: What is it like building a final assembly plant — a U.S. factory — in this moment?
John Harris: I would say lots of people talk about how excited they are about U.S. manufacturing, but that's very different than putting their money where their mouth is. Building a final assembly line, like we have — our team here is really good, that they made it feel not that hard. The challenge is the whole supply chain.
If we look at what we build here in-house at Harbinger, we have a final assembly line where we bolt parts together to make chassis. We also have two sub-component assembly lines where we take copper and make motors, and where we take cells and make batteries. All three of those lines work pretty well. We're pumping out chassis, and they roll out the door, and we sell them to people, which is great. But it’s all the stuff that goes into those, that's the most challenging. There's a lot of trade policy at certain hours of the day, on certain days of the week — depending on when we check — that is theoretically supposed to encourage us manufacturing.
But it's really not because of the volatility. It costs us an enormous amount to build the supply chain, to feed these lines. And when we have volatile trade policy, our reaction, and everyone else's reaction, is to just pause. It’s not to spend more money on U.S. manufacturing, because we were already doing that. We were spending a lot on U.S. manufacturing as part of our core approach to manufacturing.
The latest trade policy has caused us to spend less money on U.S. manufacturing — not more, because we're unclear on what is the demand environment going to be, what is the policy going to be next week? We were getting ready to make major investments to take certain manufacturing tasks in our supply chain out of China and move them to Mexico, for example. Now we’re not. We were getting ready to invest in certain kinds of automation to do things in house, and now we're waiting. So the volatility is dramatically shrinking investment in US manufacturing, including ours.
Meyer: And can you just explain, why did you make that decision to pause investment and how does trade policy affect that decision?
Harris: When we had 25% tariffs on China, if we take content out of China and move it to Mexico, we break even — if that. We might still end up underwater. That's because there's better automation in China. There's much higher labor productivity. And — this one is always shocking to people — there’s lower logistics costs. When we move stuff from Shenzhen to our factory, in many cases it costs us less than moving shipments from Monterey.

On xAI, residential solar, and domestic lithium
Current conditions: Indonesia has issued its highest alert level due to the ongoing eruption of Mount Lewotobi Laki-laki • 10 million people from Missouri to Michigan are at risk of large hail and damaging winds today • Tropical Storm Erick, the earliest “E” storm on record in the eastern Pacific Ocean, could potentially strengthen into a major hurricane before making landfall near Acapulco, Mexico, on Thursday.
The NAACP and the Southern Environmental Law Center said Tuesday that they intend to sue Elon Musk’s artificial intelligence company xAI over alleged Clean Air Act violations at its Memphis facility. Per the lawsuit, xAI failed to obtain the required permits for the use of the 26 gas turbines that power its supercomputer, and in doing so, the company also avoided equipping the turbines with technology that would have reduced emissions. “xAI’s turbines are collectively one of the largest, or potentially the largest, industrial source of nitrogen oxides in Shelby County,” the lawsuit claims.
The SELC has additionally said that residents who live near the xAI facility already face cancer risks four times above the national average, and opponents have argued that xAI’s lack of urgency in responding to community concerns about the pollution is a case of “environmental racism.” In a statement Tuesday, xAI responded to the threat of a lawsuit by claiming the “temporary power generation units are operating in compliance with all applicable laws,” and said it intends to equip the turbines with the necessary technology to reduce emissions going forward.
Shares of several residential solar companies plummeted Tuesday after the Senate Finance Committee declined to preserve related Inflation Reduction Act investment tax credits. As my colleague Matthew Zeitlin reported, Sunrun shares fell 40%, “bringing the company’s market cap down by almost $900 million to $1.3 billion,” after a brief jump at the end of last week “due to optimism that the Senate Finance bill might include friendlier language for its business model.”
That never materialized. Instead, the Finance Committee’s draft proposed terminating the residential clean energy tax credit for any systems, including residential solar, six months after the bill is signed, as well as the investment and production tax credits for residential solar. SolarEdge and Enphase also suffered from the news, with shares down 33% and 24%, respectively. You can read Matthew’s full analysis here.
Chevron announced Tuesday that it has acquired 125,000 net acres of the Smackover Formation in southwest Arkansas and northeast Texas to get into domestic lithium extraction. Chevron’s acquisition follows an earlier move by Exxon Mobil to do the same, with lithium representing a key resource for the transition from fossil fuels to renewable energy sources “that would allow the company to pivot if oil and gas demands wane in the coming decades,” Bloomberg writes.
“Establishing domestic and resilient lithium supply chains is essential not only to maintaining U.S. energy leadership but also to meeting the growing demand from customers,” Jeff Gustavson, the president of Chevron New Energies, said in a Tuesday press release. The Liberty Owl project, which was part of Chevron’s acquisition from TerraVolta Resources, is “expected to have an initial production capacity of at least 25,000 tonnes of lithium carbonate per year, which is enough lithium to power about 500,000 electric vehicles annually,” Houston Business Journal reports.
The Federal Emergency Management Agency prepared a memo titled “Abolishing FEMA” at the direction of Homeland Security Secretary Kristi Noem, describing how its functions can be “drastically reformed, transferred to another agency, or abolished in their entirety” as soon as the end of 2025. While only Congress can technically eliminate the agency, the March memo, obtained and reviewed by Bloomberg, describes potential changes like “eliminating long-term housing assistance for disaster survivors, halting enrollments in the National Flood Insurance Program, and providing smaller amounts of aid for fewer incidents — moves that by design would dramatically limit the federal government’s role in disaster response.”
In May, FEMA’s acting administrator, Cameron Hamilton, was fired one day after defending the existence of the department he’d been appointed to oversee when testifying before the House Appropriations subcommittee. An internal FEMA memo from the same month described the agency’s “critical functions” as being at “high risk” of failure due to “significant personnel losses in advance of the 2025 Hurricane Season.” President Trump has, on several occasions, expressed a desire to eliminate FEMA, as recommended by the Project 2025 playbook from the Heritage Foundation. The March “Abolishing FEMA” memo “just means you should not expect to see FEMA on the ground unless it’s 9/11, Katrina, Superstorm Sandy,” Carrie Speranza, the president of the U.S. council of the International Association of Emergency Managers, told Bloomberg.
The Spanish government on Tuesday released its report on the causes of the April 28 blackout that left much of the nation, as well as parts of Portugal, without power for more than 12 hours. Ecological Transition Minister Sara Aagesen, who heads Spain’s energy policy, told reporters that a voltage surge in the south of Spain had triggered a “chain reaction of disconnections” that led to the widespread power loss, and blamed the nation’s state-owned grid operator Red Eléctrica for “poor planning” and failing to have enough thermal power stations online to control the dynamic voltage, the Associated Press reports. Additionally, Aagesen said that utilities had preventively shut off some power plants when the disruptions started, which could have helped the system stay online. “We have a solid narrative of events and a verified explanation that allows us to reflect and to act as we surely will,” Aagesen went on, responding to criticisms that Spain’s renewable-heavy energy mix was to blame for the blackout. “We believe in the energy transition and we know it’s not an ideological question but one of this country’s principal vectors of growth when it comes to re-industrialisation opportunities.”

Shares in Sunrun, SolarEdge, and Enphase are collapsing on the Senate’s new mega-bill draft.
The residential solar rescue never happened. Shares in several residential solar companies plummeted Tuesday as the market reacted to the Senate Finance Committee’s reconciliation language, which maintains the House bill’s restriction on investment tax credits for residential solar installers and its scrapping of the tax credit for homeowners who buy their own systems.
The Solar Energy Industries Association, a solar trade group, criticized the Senate text, saying that it had only “modest improvements on several provisions” and would “pull the plug on homegrown solar energy and decimate the American manufacturing renaissance.”
Sunrun shares fell 40% Tuesday, bringing the company’s market cap down by almost $900 million to $1.3 billion, a comparable loss in value to what it sustained the day after the passage of the House reconciliation bill. The stock price had jumped up late last week due to optimism that the Senate Finance bill might include friendlier language for its business model.
Instead the Finance Committee proposal would terminate the residential clean energy tax credit for any systems, including residential solar, six months after the bill is signed. The text also zeroes out investment and production tax credits for residential solar when “the taxpayer rents or leases such property to a third party,” a common arrangement in the industry pioneered by Sunrun.
Sunrun’s third party ownership model well predates the Inflation Reduction Act and is about as old as the company itself, which was founded in 2007. The company had been claiming investment tax credits for solar before the IRA made them tech neutral. The company began securitizing solar deals in 2015 and in a 2016 securities filling, the company said that it had six deals where investors would be able to garner the lease payments and investment tax credits.
“Ain’t no sunshine for resi,” Jefferies analyst Julien Dumoulin-Smith wrote in a note to clients on Tuesday. “Overall, we view Senate's version as a negative” for Sunrun, as well as SolarEdge and Enphase, the residential solar equipment companies, whose shares are down by about 33% and 24% respectively.
“If this language is not adjusted before the bill passes the Senate floor,” Morgan Stanley analyst Andrew Perocco wrote in a note to clients, “we believe Sunrun, SolarEdge, and Enphase will trade towards our bear cases.”
Morgan Stanley had earlier estimated that cutting off home solar from tax credits would lead to a “85% contraction in residential solar volumes” due, in many cases, to solar products no longer resulting in savings on electricity bills.
That’s because the ability to lease solar equipment (or have homeowners sign power purchase agreements) and then claim tax credits sits at the core of the contemporary residential solar model.
“Our core solar service offerings are provided through our lease and power purchase agreements,” the company said in its 2024 annual report. “While customers have the option to purchase a solar energy system outright from us, most of our customers choose to buy solar as a service from us through our Customer Agreements without the significant upfront investment of purchasing a solar energy system.”
This means that to claim tax credits for the projects, they have to be investment tax credits, not home energy credits. These credits play a role in Sunrun’s extensive business raising money from investors to finance solar projects, which can then be partially monetized via tax credits.
Fund investors “can receive attractive after-tax returns from our investment funds due to their ability to utilize Commercial ITCs,” the company said in its report. The financing then “enables us to offer attractive pricing to our customers for the energy generated by the solar energy system on their homes.”
Without the ability to claim investment tax credits, Sunrun could be left having to charge higher prices to homeowners and face a higher cost of capital to raise money from investors.
“Last night’s draft text confirms the Senate intends to abruptly repeal tax credits available to homeowners who want to go solar – effectively increasing costs and limiting choice for countless Americans,” Chris Hopper, chief executive of Aurora Solar, said in an emailed statement.
