Some climate policies are safe. Some are not.
Absent a last-minute deal between a bipartisan group of senators and the Republican-led House, the federal government will shut down on Sunday. With much of the Biden administration’s climate agenda a work in progress, a shutdown could grind time-sensitive rulemakings and grantmaking activities to a halt, not to mention regular environmental protection.
But it’s not so simple. Thanks to the Inflation Reduction Act and the Infrastructure Investment and Jobs Act, much of the government’s climate work has been funded outside of the annual appropriations process and could prove fairly resilient to a shutdown. However, few agencies have released their contingency plans, and so it’s hard to parse exactly which activities will continue. The White House has been eager to use the prospect of government responsibilities going unfulfilled as leverage against Republican leaders in the House.
When we reached out to federal agencies and the White House for more information, they either declined to comment or referred us to the Office of Management and Budget. That office did not answer questions but a spokesperson said in an email that “shutdowns are disruptive and distracting, making it difficult for agencies to deliver for the American people at the same pace — even for programs with available funding — given how much time and attention must go to managing the impacts of a shutdown.”
The clock is ticking on several key upcoming climate and clean energy rules, due to the Congressional Review Act. The law allows Congress to overturn new federal rules within 60 legislative days — which can actually stretch months — by a simple majority vote, and with the president’s signature. That means if the rules aren’t finalized in time and Biden loses his re-election bid, some of the headway his agencies make to cut emissions could quickly be erased.
We talked to former staffers and lobbyists to get a handle on how a shutdown would affect climate and environmental programs throughout the federal government.

Yes, the IRS has an important role to play here. Much of the Inflation Reduction Act’s implementation is actually up to the IRS writing rules outlining how companies can qualify for tax credits. For example, the agency has yet to even propose rules to claim the lucrative tax credits for producing clean hydrogen, or finalize others on electric vehicle battery and mineral sourcing requirements, or apprenticeship requirements, or how tax-exempt entities can qualify for funding.
It’s not clear whether the IRS would continue to chip away at these processes if there’s a shutdown. When one loomed last year, the agency’s contingency plan said that its more than 80,000 employees would still be able to work thanks to “supplemental appropriations available through September 30, 2031.” But whether that will be the case this year remains unclear.
The National Treasury Employees Union, which represents IRS workers, told its members that the IRS would “partially close” should a funding deal not be reached by September 30, according to the Federal News Network. The NTEU did not respond to a request for comment. A Treasury spokesperson also declined to comment and said that contingency plans would be released later this week.
Even if the IRS continues working on the rules, it will likely not be able to engage directly with industry or outside groups while the government remains closed, a former Department of Energy official, who asked not to be named, told us. “There’s still a lot of guidance that we’re waiting for, it’s critically important that it continues to move forward,” the former official said. “Activities that are people driven — negotiating, educating, and guidance — those are going to be much more impacted.”
There also wouldn’t be any of the announcements and public and private engagement that takes up much of the rulewriting process, the former official said.
And even if the IRS continues to work at something like its full potential, any work it has to do with other agencies whose funding runs out could be impacted, a lobbyist who works on energy issues pointed out to us. “Carryover funds may mean a short shutdown isn't a big deal, but a prolonged one could compound what is already a huge strain on agency resources and bandwidth,” the lobbyist said.
The EPA is in the middle of several rulemakings that are essential to U.S. climate progress, including regulations on cars and trucks, as well as power plants, and the experts we spoke with did not think a government shutdown would put the rules at risk. Stan Meiburg, a former EPA acting deputy director, told us he noticed the agency had denied petitions from stakeholders to extend the comment period for the car emissions proposal, which tells him staffers are trying to get the rules out the door to safeguard them from a future administration.
“I think both of those standards, while they may be delayed a couple of weeks from their original time tables, will still meet the deadlines the agency has in mind for them,” he told us.
The EPA is also the lead administrator for about $41 billion from the Inflation Reduction Act, including billions in clean energy grants. That’s not expected to be affected by a shutdown, since the IRA included some budget for staffing. However, the agency’s regular grant work, including funding distributed to states to conduct their environmental protection work, will come to a screeching halt, said Nicole Cantello, a lawyer at the agency who spoke with us in her capacity as president of the government employees union local in Chicago.
Cancello said that overall, the agency would be “profoundly affected” by a shutdown with 93% of its staff expected to be furloughed. A lot of the country’s air and water quality monitoring occurs at the state and local level, but some environmental enforcement capacity will certainly be lost, she told us. During the last government shutdown, she was in the middle of an enforcement case where the agency was collecting air quality data at the fenceline of a polluting facility that was directly next to a neighborhood. All of the data was coming into employees’ inboxes, she said, “and they couldn’t look to see whether or not that data showed that these people were endangering that community or not. I remember how frustrating that felt.”
Meiburg, who was with the agency through several shutdowns, told us they have disrupted time-sensitive research projects and caused supply chain breakdowns. The EPA inspects all pesticides that are imported into the country, and during past shutdowns the pesticides began piling up in warehouses, he said.
But Meiburg said there’s typically a small number of people who will still be on call in case of an environmental disaster, like the Maui wildfires or the toxic train derailment in East Palestine.
The Department of Energy plays a major role in climate policy, including overseeing the Loan Programs Office and making grants and funding demonstration projects for early stage energy technology like long duration batteries, advanced geothermal, and direct air capture. Many of those activities would likely continue.
According to the agency’s publicly available “lapse plan,” about 5,500 of its around 14,000 full-time employees would stay on in case of a shutdown. The multi-year appropriations provided by IRA and the infrastructure law would keep just over 1,000 of those employees on the job, according to the document: “As of August 4, 2023, 1,040 DOE employees were fully or partially funded by multi-year appropriations; these employees would continue to perform funded work after the exhaustion of DOE base funding.” Around 3,000 employees of the Bonneville Power Administration, the public power company in the Pacific Northwest, would continue working because it funds itself through power sales.
In the case of a shutdown lasting less than about a week, “It is anticipated that there would be no disruption to DOE operations during a short lapse in appropriations,” a guide to the shutdown published on the DOE website says. “DOE has historically had sufficient previously appropriated funds that remain available to support operations during a short term lapse.”

Instead of rocket fuel, they’re using biomass.
Arbor Energy might have the flashiest origin story in cleantech.
After the company’s CEO, Brad Hartwig, left SpaceX in 2018, he attempted to craft the ideal resume for a future astronaut, his dream career. He joined the California Air National Guard, worked as a test pilot at the now-defunct electric aviation startup Kitty Hawk, and participated in volunteer search and rescue missions in the Bay Area, which gave him a front row seat to the devastating effects of wildfires in Northern California.
That experience changed everything. “I decided I actually really like planet Earth,” Hartwig told me, “and I wanted to focus my career instead on preserving it, rather than trying to leave it.” So he rallied a bunch of his former rocket engineer colleagues to repurpose technology they pioneered at SpaceX to build a biomass-fueled, carbon negative power source that’s supposedly about ten times smaller, twice as efficient, and eventually, one-third the cost of the industry standard for this type of plant.
Take that, all you founders humble-bragging about starting in a dingy garage.
“It’s not new science, per se,” Hartwig told me. The goal of this type of tech, called bioenergy with carbon capture and storage, is to combine biomass-based energy generation with carbon dioxide removal to achieve net negative emissions. Sounds like a dream, but actually producing power or heat from this process has so far proven too expensive to really make sense. There are only a few so-called BECCS facilities operating in the U.S. today, and they’re all just ethanol fuel refineries with carbon capture and storage technology tacked on.
But the advances in 3D printing and computer modeling that allowed the SpaceX team to build an increasingly simple and cheap rocket engine have allowed Arbor to move quickly into this new market, Hartwig explained. “A lot of the technology that we had really pioneered over the last decade — in reactor design, combustion devices, turbo machinery, all for rocket propulsion — all that technology has really quite immediate application in this space of biomass conversion and power generation.”
Arbor’s method is poised to be a whole lot sleeker and cheaper than the BECCS plants of today, enabling both more carbon sequestration and actual electricity production, all by utilizing what Hartwig fondly refers to as a “vegetarian rocket engine.” Because there’s no air in space, astronauts have to bring pure oxygen onboard, which the rocket engines use to burn fuel and propel themselves into the stratosphere and beyond. Arbor simply subs out the rocket fuel for biomass. When that biomass is combusted with pure oxygen, the resulting exhaust consists of just CO2 and water. As the exhaust cools, the water condenses out, and what’s left is a stream of pure carbon dioxide that’s ready to be injected deep underground for permanent storage. All of the energy required to operate Arbor’s system is generated by the biomass combustion itself.
“Arbor is the first to bring forward a technology that can provide clean baseload energy in a very compact form,” Clea Kolster, a partner and Head of Science at Lowercarbon Capital told me. Lowercarbon is an investor in Arbor, alongside other climate tech-focused venture capital firms including Gigascale Capital and Voyager Ventures, but the company has not yet disclosed how much it’s raised.
Last month, Arbor signed a deal with Microsoft to deliver 25,000 tons of permanent carbon dioxide removal to the tech giant starting in 2027, when the startup’s first commercial project is expected to come online. As a part of the deal, Arbor will also generate 5 megawatts of clean electricity per year, enough to power about 4,000 U.S. homes. And just a few days ago, the Department of Energy announced that Arbor is one of 11 projects to receive a combined total of $58.5 million to help develop the domestic carbon removal industry.
Arbor’s current plan is to source biomass from forestry waste, much of which is generated by forest thinning operations intended to prevent destructive wildfires. Hartwig told me that for every ton of organic waste, Arbor can produce about one megawatt hour of electricity, which is in line with current efficiency standards, plus about 1.8 tons of carbon removal. “We look at being as efficient, if not a little more efficient than a traditional bioenergy power plant that does not have carbon capture on it,” he explained.
The company’s carbon removal price targets are also extremely competitive —- in the $50 to $100 per ton range, Hartwig said. Compare that to something like direct air capture, which today exceeds $600 per ton, or enhanced rock weathering, which is usually upwards of $300 per ton. “The power and carbon removal they can offer comes at prices that meet nearly unlimited demand,”Mike Schroepfer, the founder of Gigascale Capital and former CTO of Meta, told me via email. Arbor benefits from the fact that the electricity it produces and sells can help offset the cost of the carbon removal, and vice versa. So if the company succeeds in hitting its cost and efficiency targets, Hartwig said, this “quickly becomes a case for, why wouldn’t you just deploy these everywhere?”
Initial customers will likely be (no surprise here) the Microsofts, Googles and Metas of the world — hyperscalers with growing data center needs and ambitious emissions targets. “What Arbor unlocks is basically the ability for hyperscalers to stop needing to sacrifice their net zero goals for AI,” Kolster told me. And instead of languishing in the interminable grid interconnection queue, Hartwig said that providing power directly to customers could ensure rapid, early deployment. “We see it as being quicker to power behind-the-meter applications, because you don’t have to go through the process of connecting to the grid,” he told me. Long-term though, he said grid connection will be vital, since Arbor can provide baseload power whereas intermittent renewables cannot.
All of this could serve as a much cheaper alternative, to say, re-opening shuttered nuclear facilities, as Microsoft also recently committed to doing at Three Mile Island. “It’s great, we should be doing that,” Kolster said of this nuclear deal, “but there’s actually a limited pool of options to do that, and unfortunately, there is still community pushback.”
Currently, Arbor is working to build out its pilot plant in San Bernardino, California, which Hartwig told me will turn on this December. And by 2030, the company plans to have its first commercial plant operating at scale, generating 100 megawatts of electricity while removing nearly 2 megatons of CO2 every year. “To put it in perspective: In 2023, the U.S. added roughly 9 gigawatts of gas power to the grid, which generates 18 to 23 megatons of CO2 a year,” Schroepfer wrote to me. So having just one Arbor facility removing 2 megatons would make a real dent. The first plant will be located in Louisiana, where Arbor will also be working with an as-yet-unnamed partner to do the carbon storage.
The company’s carbon credits will be verified with the credit certification platform Isometric, which is also backed by Lowercarbon and thought to have the most stringent standards in the industry. Hartwig told me that Arbor worked hand-in-hand with Isometric to develop the protocol for “biogenic carbon capture and storage,” as the company is the first Isometric-approved supplier to use this standard.
But Hartwig also said that government support hasn’t yet caught up to the tech’s potential. While the Inflation Reduction Act provides direct air capture companies with $180 per ton of carbon dioxide removed, technology such as Arbor’s only qualifies for $85 per ton. It’s not nothing — more than the zero dollars enhanced rock weathering companies such as Lithos or bio-oil sequestration companies such as Charm are getting. “But at the same time, we’re treated the same as if we’re sequestering CO2 emissions from a natural gas plant or a coal plant,” Hartwig told me, as opposed to getting paid for actual CO2 removal.
“I think we are definitely going to need government procurement or involvement to actually hit one, five, 10 gigatons per year of carbon removal,” Hartwig said. Globally, scientists estimate that we’ll need up to 10 gigatons of annual CO2 removal by 2050 in order to limit global warming to 1.5 degrees Celsius. “Even at $100 per ton, 10 gigatons of carbon removal is still a pretty hefty price tag,” Hartwig told me. A $100 billion price tag, to be exact. “We definitely need more players than just Microsoft.”
New research out today shows a 10-fold increase in smoke mortality related to climate change from the 1960s to the 2010.
If you are one of the more than 2 billion people on Earth who have inhaled wildfire smoke, then you know firsthand that it is nasty stuff. It makes your eyes sting and your throat sore and raw; breathe in smoke for long enough, and you might get a headache or start to wheeze. Maybe you’ll have an asthma attack and end up in the emergency room. Or maybe, in the days or weeks afterward, you’ll suffer from a stroke or heart attack that you wouldn’t have had otherwise.
Researchers are increasingly convinced that the tiny, inhalable particulate matter in wildfire smoke, known as PM2.5, contributes to thousands of excess deaths annually in the United States alone. But is it fair to link those deaths directly to climate change?
A new study published Monday in Nature Climate Change suggests that for a growing number of cases, the answer should be yes. Chae Yeon Park, a climate risk modeling researcher at Japan’s National Institute for Environmental Studies, looked with her colleagues at three fire-vegetation models to understand how hazardous emissions changed from 1960 to 2019, compared to a hypothetical control model that excluded historical climate change data. They found that while fewer than 669 deaths in the 1960s could be attributed to climate change globally, that number ballooned to 12,566 in the 2010s — roughly a 20-fold increase. The proportion of all global PM2.5 deaths attributable to climate change jumped 10-fold over the same period, from 1.2% in the 1960s to 12.8% in the 2010s.
“It’s a timely and meaningful study that informs the public and the government about the dangers of wildfire smoke and how climate change is contributing to that,” Yiqun Ma, who researches the intersection of climate change, air pollution, and human health at the Yale School of Medicine, and who was not involved in the Nature study, told me.
The study found the highest climate change-attributable fire mortality values in South America, Australia, and Europe, where increases in heat and decreases in humidity were also the greatest. In the southern hemisphere of South America, for example, the authors wrote that fire mortalities attributable to climate change increased from a model average of 35% to 71% between the 1960s and 2010s, “coinciding with decreased relative humidity,” which dries out fire fuels. For the same reason, an increase in relative humidity lowered fire mortality in other regions, such as South Asia. North America exhibited a less dramatic leap in climate-related smoke mortalities, with climate change’s contribution around 3.6% in the 1960s, “with a notable rise in the 2010s” to 18.8%, Park told me in an email.
While that’s alarming all on its own, Ma told me there was a possibility that Park’s findings might actually be too conservative. “They assume PM2.5 from wildfire sources and from other sources” — like from cars or power plants — “have the same toxicity,” she explained. “But in fact, in recent studies, people have found PM2.5 from fire sources can be more toxic than those from an urban background.” Another reason Ma suspected the study’s numbers might be an underestimate was because the researchers focused on only six diseases that have known links to PM2.5 exposure: chronic obstructive pulmonary disease, lung cancer, coronary heart disease, type 2 diabetes, stroke, and lower respiratory infection. “According to our previous findings [at the Yale School of Medicine], other diseases can also be influenced by wildfire smoke, such as mental disorders, depression, and anxiety, and they did not consider that part,” she told me.
Minghao Qiu, an assistant professor at Stony Brook University and one of the country’s leading researchers on wildfire smoke exposure and climate change, generally agreed with Park’s findings, but cautioned that there is “a lot of uncertainty in the underlying numbers” in part because, intrinsically, wildfire smoke exposure is such a complicated thing to try to put firm numbers to. “It’s so difficult to model how climate influences wildfire because wildfire is such an idiosyncratic process and it’s so random, ” he told me, adding, “In general, models are not great in terms of capturing wildfire.”
Despite their few reservations, both Qiu and Ma emphasized the importance of studies like Park’s. “There are no really good solutions” to reduce wildfire PM2.5 exposure. You can’t just “put a filter on a stack” as you (sort of) can with power plant emissions, Qiu pointed out.
Even prescribed fires, often touted as an important wildfire mitigation technique, still produce smoke. Park’s team acknowledged that a whole suite of options would be needed to minimize future wildfire deaths, ranging from fire-resilient forest and urban planning to PM2.5 treatment advances in hospitals. And, of course, there is addressing the root cause of the increased mortality to begin with: our warming climate.
“To respond to these long-term changes,” Park told me, “it is crucial to gradually modify our system.”
On the COP16 biodiversity summit, Big Oil’s big plan, and sea level rise
Current conditions: Record rainfall triggered flooding in Roswell, New Mexico, that killed at least two people • Storm Ashley unleashed 80 mph winds across parts of the U.K. • A wildfire that broke out near Oakland, California, on Friday is now 85% contained.
Forecasters hadn’t expected Hurricane Oscar to develop into a hurricane at all, let alone in just 12 hours. But it did. The Category 1 storm made landfall in Cuba on Sunday, hours after passing over the Bahamas, bringing intense rain and strong winds. Up to a foot of rainfall was expected. Oscar struck while Cuba was struggling to recover from a large blackout that has left millions without power for four days. A second system, Tropical Storm Nadine, made landfall in Belize on Saturday with 60 mph winds and then quickly weakened. Both Oscar and Nadine developed in the Atlantic on the same day.

The COP16 biodiversity summit starts today in Cali, Colombia. Diplomats from 190 countries will try to come up with a plan to halt global biodiversity loss, aiming to protect 30% of land and sea areas and restore 30% of degraded ecosystems by 2030. Discussions will revolve around how to monitor nature degradation, hold countries accountable for their protection pledges, and pay for biodiversity efforts. There will also be a big push to get many more countries to publish national biodiversity strategies. “This COP is a test of how serious countries are about upholding their international commitments to stop the rapid loss of biodiversity,” said Crystal Davis, Global Director of Food, Land, and Water at the World Resources Institute. “The world has no shot at doing so without richer countries providing more financial support to developing countries — which contain most of the world’s biodiversity.”
A prominent group of oil and gas producers has developed a plan to roll back environmental rules put in place by President Biden, The Washington Post reported. The paper got its hands on confidential documents from the American Exploration and Production Council (AXPC), which represents some 30 producers. The documents include draft executive orders promoting fossil fuel production for a newly-elected President Trump to sign if he takes the White House in November, as well as a roadmap for dismantling many policies aimed at getting oil and gas producers to disclose and curb emissions. AXPC’s members, including ExxonMobil, ConocoPhillips, and Hess, account for about half of the oil and gas produced in the U.S., the Post reported.
A new report from the energy think tank Ember looks at how the uptake of electric vehicles and heat pumps in the U.K. is affecting oil and gas consumption. It found that last year the country had 1.5 million EVs on the road, and 430,000 residential heat pumps in homes, and the reduction in fossil fuel use due to the growth of these technologies was equivalent to 14 million barrels of oil, or about what the U.K. imports over a two-week span. This reduction effect will be even stronger as more and more EVs and heat pumps are powered by clean energy. The report also found that even though power demand is expected to rise, efficiency gains from electrification and decarbonization will make up for this, leading to an overall decline in energy use and fossil fuel consumption.

The world’s sea levels are projected to rise by more than 6 inches on average over the next 30 years if current trends continue, according to a new study published in the journal Nature. “Such rates would represent an evolving challenge for adaptation efforts,” the authors wrote. By examining satellite data, the researchers found that sea levels have risen by about .4 inches since 1993, and that they’re rising faster now than they were then. In 1993 the seas were rising by about .08 inches per year, and last year they were rising at .17 inches per year. These are averages, of course, and some areas are seeing much more extreme changes. For example, areas around Miami, Florida, have already seen sea levels rise by 6 inches over the last 31 years.
“As the climate crisis grows more urgent, restoring faith in government will be more important than ever.” –Paul Waldman writing for Heatmap about the profound implications of America becoming a low-trust society.
