Here’s what the American Conservation Coalition hopes to hear at the first Republican debate.

After the first Republican presidential debate wraps up in Milwaukee on Wednesday night, the candidates will be invited to an unusual reception. The official afterparty has been sponsored by the American Conservation Coalition, a young conservative advocacy group that has made a name for itself advocating for Republican Party leaders to act on climate change.
The group was founded in 2017 by Benji Backer, a student at the University of Washington who wanted to see the party return to its Rooseveltian environmental roots, and was convinced that his peers felt the same. While polls consistently show that climate change is not a priority for Republican voters — many don’t even consider it a threat — the picture changes when broken down by age, with younger generations wanting the government to do more on the issue.
The ACC has since grown into a network of about 20,000 members and helped pass a handful of bipartisan bills under both the Trump and Biden administrations, including the Great Outdoors Act, which directed billions to the National Parks Service for deferred maintenance, and the Growing Climate Solutions Act, designed to help farmers engage in carbon markets. In general, the ACC wants to see the government invest more in innovation, conservation, and domestic energy production, and mostly get out of the market’s way. Most recently, it has been pushing for Congress to streamline environmental reviews to speed up energy development, an issue often summarized as “permitting reform.”
But the ACC has faced an uphill battle. Climate change is still polarizing in Congress, and solutions are increasingly framed by conservative officials and pundits in culture war terms. Now, gearing up for the first presidential election since the group’s founding, the ACC hopes to convince Republican candidates, who have been mostly reticent about the warming planet, to start talking about it. “Fewer than half of Americans believe that Biden's climate policies are taking the country in the right direction,” the ACC’s new president, Christopher Barnard, told me, citing a recent Pew survey. “That offers an incredible opportunity for Republicans to offer a more compelling alternative, and right now, we're not really doing that.”
I spoke to Barnard just after he landed in Milwaukee on Tuesday about the "electoral ticking time bomb" Republicans face, what questions he wants candidates to speak to at the debate, and the group's hopes for sponsoring the afterparty. Our conversation has been lightly edited for concision and clarity.

What has the American Conservation Coalition been up to in 2023 so far?
The 118th Congress marks the first time in quite a while that we've had Republicans in charge of the House of Representatives. We've looked at that as an opportunity for Republicans to take a seat at the table when it comes to pushing for policy that can help tackle climate change, strengthen energy security, and reduce emissions. And so we've done a lot of engagement on Capitol Hill on things like permitting reform, nuclear energy, the farm bill, nature-based solutions, critical minerals.
We feel like we're in a really interesting moment right now, where, from our perspective, all of the top solutions to climate and energy problems are things that conservatives can not only get behind, but can actually lead on.
When you say the top solutions are things that Republicans can lead on, are you seeing that leadership in this Congress?
Yeah. Especially on the policy side of things, we saw how much McCarthy and Congressman Graves and Chairman Westerman have been pushing for permitting reform. We obviously got a taste of that in the debt ceiling negotiation. We would like to see much more and that's something that Republicans are still pushing for, which I think is the number one thing right now we can do to tackle climate change.
There is still a little bit of a disconnect between that and their rhetoric on the issue. When it comes to nuclear or critical minerals or permitting reform, there's really a huge opportunity for Republicans to retake the climate and environmental conversation and say, Look, these are conservative, limited-government, small market-based solutions, that would actually really help climate change more than say, the Green New Deal. And they're not really putting it that way. So while I've been pleased with some of the policy progress, we want to see Republicans be bolder and more ambitious and really start saying the things that are going to win them back the youth vote that they've lost.
What kinds of questions do you hope to see the presidential candidates asked about climate change tomorrow?
If I were to ask them a question, I would ask, what do you tell a young conservative, who loves America, who is also concerned about environmental and climate issues? What is your positive vision of the future to tackle this problem?
I think there's a tendency for questions around climate change to be loaded with words that are quite partisan. For example, the term climate crisis is incredibly unpopular with Americans in general and obviously Republicans don't respond very well to that. But asking about things like how do you tackle pollution? How do you make sure that we have a thriving planet for future generations? How do you ensure clean energy, all-of-the-above energy? Those are all things that Republicans are actually very on board with.
Also, what their plan is for American strength on the international stage. Battery technologies, EVs, wind and solar, critical minerals, all these crucial components of the clean energy future are being taken over by China because they see what's going to happen. They want to be the Saudi Arabia of clean energy, and we cannot allow that to happen. So any Republican answer on foreign policy should include, what are we going to do to be the most innovative country in the world? To have secure supply chains? To work with our allies? I think those are interconnected with other issues that Americans and Republicans care about, which is national security, energy security, etc.
What other climate-related messages or policies does the ACC want to hear the candidates talk about?
ACC has a platform called the Climate Commitment with six big ideas to tackle climate change rooted in limited government, market-based, conservative ideals. Some of those that I think would make perfect sense for a Republican candidate to bring up would be the importance of unleashing all American energy. So it's not just fossil fuels, but it’s unleashing nuclear energy, unleashing wind and solar, getting the government-imposed barriers out of the way of these energy sources and allowing them all to thrive and compete in the marketplace.
I think another one is how America's rural communities, farmers, ranchers, hunters, can be part of tackling climate change and protecting the environment. Those are super conservative, red parts of the country that actually have a huge role to play, whether it's farmers implementing sustainable practices on their land that reduces emissions, or rural communities hosting clean energy sites. There's so much that rural communities can do to be part of the solution.
What does it mean for ACC to be sponsoring the afterparty for the debate? What are you hoping to get out of it?
It’s to show that Republicans take this issue seriously now. They understand that they have a huge electoral ticking time bomb if they don't talk about it. We've seen already in the last few months how some of the impacts of climate change, whether it's heat waves, or whatever else it might be— people are realizing the importance of this.
ACC hosting this shows that it's entirely possible to be both an environmentalist and a conservative. They are, in many ways, two sides of the same coin. That's really the message that we want to bring to this, and to push Republicans, especially those standing up on the stage, to come up with a compelling vision of how they're going to tackle this issue that young conservatives can get excited about.
What did you mean when you said they have an electoral ticking time bomb?
If you look at demographic numbers, by 2028, millennials and Gen Z will be a majority of potential voters. By next decade, they will be over 60% of potential voters. Polling routinely shows that climate and environment are the top three, top five issues for them.
And young people are increasingly swinging elections. We saw in the midterms that in all the key Senate races that Republicans lost, young people showed out in historic numbers and overwhelmingly voted for Democrats. If Republicans don't regain the trust of young people on this issue, they face losing an entire generation of voters that are increasingly prioritizing this.
At this after-party, if you're coming face to face with the candidates, and you're trying to convince them why they should make climate change a bigger part of their campaign, what’s your argument? When right now, the majority of the Republican Party does not see it as a priority?
We know that this is an issue that matters enormously in general elections, whether it's trying to peel off independent voters, whether it's suburban moms, whether it's young voters. In some districts, it's just a few thousand votes that can make the difference. So I would tell them you need to, at the very least, have a bit of a platform to go off if you were to get to a general. I think DeSantis is really well-positioned for this, because he can point to his strong conservation track record in Florida in his time as governor — a lot of work on clean air, clean water, healthy communities. Base voters won't be upset about that, but that also allows him a jumping off point for a general election.
There's plenty of examples around the country of red states where governors have embraced things like EVs or wind and solar because they're creating jobs in their state. Wind and solar are much more popular with Republicans than people might think. And so I think there's ways that you can talk about this issue that don't evoke a negative reaction.
Which candidates are you most looking forward to hearing from tomorrow night?
I'm interested in seeing what DeSantis has to say after his campaign faltering, and seeing if he can stage a comeback and what that might look like. And in the past, ACC has been impressed by things that Tim Scott has said and done. I'll be interested to see what his “happy warrior” approach will look like in the debate. We did a video with Nikki Haley about what the conservative alternative to the green New Deal looks like, and so I’m interested to see what she's going to bring to the table.
What does it say to you that Donald Trump has decided not to participate in the debate tomorrow?
I was honestly very disappointed by it. Because my general sense is that if you want to have the American people vote for you, you should be willing to stand on stage and make that case why they should vote for you.

Current conditions: The Pineapple Express, an atmospheric river originating in the Pacific near Hawaii, is arriving in the Southwest laden with heavy rain that’s set to flood the region • Indonesia has the worst air quality in the world as forest fires rage along Sumatra’s southern coast • A cross-country storm will soak much of the United States on Tuesday’s Election Day.
The Senate’s grand compromise to simplify federal permitting on energy projects would likely drop emissions slightly as the benefits to accelerating deployments of clean energy infrastructure outweigh the boost the legislation could give to fossil fuels. Even under the worst-case scenario, emissions remain on the same trajectory as today. That’s according to a hotly anticipated new analysis by the Rhodium Group, the consultancy whose U.S. emissions estimates are among the most widely cited in American politics. The report, shared first with my colleague Emily Pontecorvo, found that provisions in the Bipartisan American Affordability and Jobs Act largely counteract each other on climate. The bill makes building transmission lines much easier, a key step to patching more renewables onto the grid. But it also makes new gas pipelines simpler to permit, clearing the way for a buildout of the infrastructure for the fossil fuel already dominating U.S. electricity and heating systems. Still, under the best-case scenario, the legislation could cut U.S. economy-wide emissions by 5% below where they would otherwise go in 2040. The bill could also slash energy bills by $78 per year and support construction of more than 200 gigawatts of clean energy capacity, as compared to a world where it didn’t pass. The Rhodium report is at least the second analysis yet to find that the bill could modestly lower emissions. The first, as I reported last week, came from the think tank Resources for the Future, which saw a slight drop in power-sector emissions relative to a world without BAAJA.
If overhauling national permitting rules to make building green energy infrastructure easier doesn’t work to lower emissions, traditional negotiations in favor of regulations that can deliver cuts looks no more promising. Two weeks of United Nations-led talks in Armenia ended Saturday without a settled approach to meeting 2030 deadlines for preserving more nature. “We don’t need to spend more to close the biodiversity funding gap, we need to spend better,” Marina Von Weissenberg, a Finnish senior ministerial advisor, said in a statement. “Governments have a real opportunity here to reshape public spending with future generations in mind, but they can’t do it alone. International coordination is key to giving governments the confidence to lead change.”
Last week, my colleague Katie Brigham published a detailed feature highlighting China’s tightening grip over the global supply chain for electrolyzers, the technology that zaps water with electricity to separate the molecule’s hydrogen from its oxygen and harvest the former as fuel. Keen readers of this newsletter recognize the story. Even before the Iran War, China had beefed up its public support for green hydrogen and related technologies. After the conflict constricted the flow of oil through the Strait of Hormuz, the People’s Republic redoubled its efforts. Quite literally. New data from the National Energy Administration shows that investments into the hydrogen industry doubled in the first nine months of this year, according to Hydrogen Insight.
Fermi America went public in a gangbusters initial public offering last year as the company, with a board of directors including former Texas governor and U.S. Secretary of Energy Rick Perry, pledged to build the world’s largest data center and power the facility with gas and four large-scale Westinghouse AP1000 nuclear reactors. In April, the chief executive and chief financial officer quit. The board room drama continued into the next month. The company’s stock recovered somewhat over the summer as investors bet on a turnaround pegged to a series of deals with companies looking to lease space on its future servers. But fresh chaos enveloped the startup Friday when The Texas Tribune reported that Perry had failed to earn enough support from the board of directors to win reelection to his seat.
In a statement posted to X on Friday evening, Fermi said that neither Perry nor investor Jeffrey Stein had been removed from the company’s board. “In fact, both Governor Perry and Jeffrey Stein received a majority of the votes cast by shareholders,” the statement read. “Let’s be clear: Governor Perry and Mr. Stein remain members of Fermi’s Board of Directors and will continue serving until their successors are duly elected. Both remain eligible for reelection.”

If you thought the fine particulate matter from last year’s catastrophic Los Angeles firestorm was bad, you weren’t thinking imaginatively enough about just how dangerous all that airborne material could be. A new study published in the journal Science Advances suggests that upward of 7 million people were exposed to high levels of airborne lead and other toxic metals released when homes and vehicles caught flame. The January 2025 Eaton inferno that destroyed more than 9,400 buildings and killed 19 people spewed 80 times the normal concentration of lead found in the atmosphere through a plume that settled over 70% of the Los Angeles metropolitan area. “I can envision that in the future we have these evacuation zones for smoke exposure as well,” Haroula Baliaka, the study’s lead author, who was a PhD candidate at Caltech last year, told Bloomberg. “Unfortunately, this is not a one-time event. It’s a new reality and we need to adapt to it and we need to do it sooner rather than later.”
The findings come a week after a study published in JAMA Pediatrics showed a link between wildfire smoke exposure during pregnancy and autism diagnoses in children. The research from Rutgers University examined 893,212 mother-child pairs enrolled in Medicaid, with children born between 2007 and 2014. Each increase of 0.75 micrograms per cubic meter in average concentrations of wildfire-related air pollution during pregnancy was associated with a 30% higher risk of a subsequent autism diagnosis. Exposure in the second and third trimesters had the highest risk. “Wildfire smoke can travel far beyond the communities where fires are burning, and exposure may occur even when smoke is not visible,” Stefania Papatheodorou, an epidemiologist at the Rutgers School of Public Health and lead author of the study, said in a press release. “Our findings highlight the importance of awareness of wildfire events and their potential effects on air quality during pregnancy.”
The United Kingdom is building out more than 10 gigawatts of offshore wind as London looks to shore up its electricity supplies amid the global energy shock. But Chancellor of the Exchequer John Healey said he would veto any offshore wind projects that don’t lower bills. While clean power is “how we break the grip of international gas prices on our bills,” he said the infrastructure “has to come at the right pace, in the right places, with the grid to carry it.” The statement fueled what The Guardian called “concerns that the government is moving away from the pro-renewables agenda.”
Meanwhile, the U.S. midterms aren’t the only election this week. In Sunday’s runoff election, Bulgaria’s pro-Russian acting President Iliana Iotova appeared to eke out a victory over the former prime minister Andrei Gyurov, a pro-Western banker. Her win unites the government with her close ally, Prime Minister Rumen Radev, ensuring stronger support for the leader’s two signature energy policies. One, a plan to build a pair of Westinghouse AP1000s at the Kozloduy nuclear plant, is scheduled to advance to the next planning stage next year. The other, the easing of sanctions on Russian uranium to ensure a supply of fuel for the plant’s existing reactors, looks likely to continue under Iotova’s friendly diplomacy with the Kremlin.
William Nordhaus, the pioneering Yale University economist who won the Nobel Prize in 2018 for integrating climate change into macroeconomic analysis, has died at 85 following a battle with an aggressive form of brain cancer. His nephew, Ted Nordhaus of the Breakthrough Institute, referred to his father, Robert Nordhaus, as “the original environmental lawyer and Bill as the original environmental economist,” he wrote in a blog post after his uncle’s passing. “It is safe to say that the Nordhaus brothers were doing environmental law and economics, respectively, long before either label existed. Not bad for two kids who grew up in the intellectual hotbed of Albuquerque, New Mexico, population 40,000, during and after the second world war.” Their legacies are something of the Nordhaus family brand: Pragmatism. May his memory be a blessing.
Even in the worst case scenario, BAAJA wouldn't increase emissions, an analysis by the Rhodium Group concludes.
The bipartisan permitting reform bill is likely to slightly cut greenhouse gas emissions and lower electricity bills by 2040 — or at worst leave emissions on the same trajectory that they are on today — as compared to the status quo, according to a new analysis of many of its provisions by the Rhodium Group, an independent research firm.
The analysis examines the policies in the Bipartisan American Affordability and Jobs Act, or BAAJA, that would have the most-clear cut effects on climate pollution and the energy system. It is the most comprehensive account of the bill’s effects on emissions so far, although it does not examine all of its provisions.
The bill is hard to analyze because — unlike recent partisan energy bills, such as the Inflation Reduction Act or President Trump’s tax and spending bill — its effects on the climate are more ambiguous and often seem to counteract each other. BAAJA will make it easier to build not only long-distance transmission lines, which are essential for clean energy, but also natural gas pipelines, which can expand fossil fuel production.
Yet the climate benefits likely outweigh or balance out the harms, at least among the studied policies, the report finds. In the best case scenario, the bill could cut U.S. economy-wide emissions by 4%, reduce energy bills by $78 per year, and drive more than 200 gigawatts of new clean energy capacity by 2040, compared to status quo policy. In a worst case scenario, greenhouse gas emissions would remain unchanged on their current trajectory.
The results should be viewed as more directionally instructive than a precise accounting of the legislation, Ben King, an energy and climate director at Rhodium, told me.
“We don’t see emissions increasing because of the bill,” King said. “This bill should drive some emission reductions, it should drive some more clean energy on the grid, and it should drive electricity bills down. And given the complexity of the bill, that’s what we can say at this point.”
The analysis does not look at the bill’s permitting certainty provisions, which Democrats initially sought to stop President Trump’s war on wind but have become one of its thorniest sections. Rhodium’s modeling is also a crude tool for assessing transmission policy, since the model can look only at economic inputs such as supply and demand, and not the physical reality of the U.S. grid, such as where transmission lines run or where the bottlenecks are.
It is the second analysis to find that the bill could modestly lower carbon pollution. A more limited report focusing only on the power grid, published last week by the think tank Resources for the Future, found the legislation could cut electricity emissions by 6% while reducing power bills by $350 billion through 2041.
The effects of the bill may sound small, but BAAJA is not a climate bill. It’s not engineered to reduce reliance on fossil fuels or boost clean energy technologies. Its overarching purpose is to address various federal bottlenecks that bog down America’s ability to build stuff, whether that’s a pipeline or a highway or a power line or a solar farm. So it’s not entirely surprising that it’s not expected to have a dramatic effect on emissions.
The reason it’s a priority for Senate climate champions is that many of its provisions are important precursors to decarbonizing the U.S. economy more quickly. By enabling faster expansion of the power grid, the bill would put the country in a much better position to transition to clean energy. After Joe Biden’s big climate bill, the Inflation Reduction Act, passed in 2022, Princeton University researchers found that the country’s slow buildout of transmission lines would be a major obstacle to gleaning the law’s benefits. Unless the country more than doubled the rate of transmission expansion, they wrote, more than 80% of the IRA’s emission reduction potential by 2030 would be lost.
BAAJA could nearly triple the build rate of high-voltage transmission, the Rhodium Group found, from an average of about 0.7 terawatt-miles added per year over the past decade to an average annual pace of 1.9 to 2.6 terawatt-miles through 2040. Because Republicans and President Trump have repealed so many of the IRA’s provisions, this won’t drive as much clean energy as the Princeton researchers expected, but Rhodium estimates that by 2040, BAAJA would help between 17 and 249 gigawatts of clean resources get built compared to a world without it.
The growing grid is the main reason why the bill cuts energy costs, because it enables more lower-cost resources to connect to the grid. The bill’s requirement that data centers pay the full cost of connecting to the grid also puts downward pressure on electricity rates.
“If your goal is to do climate policy in the future, this is an important down payment to making progress there,” King said.
The authors studied the bill’s provisions under a range of economic assumptions, including a “best case” scenario in which clean energy gets cheaper and easily outcompetes natural gas, and a “worst case” scenario where natural gas prices collapse and the inexpensive fuel keeps dominating the U.S. energy system.
The authors limited their analysis to the bill’s provisions that speed up transmission line and natural gas pipeline permitting. They assumed that when you make it easier to approve transmission lines, the lines get cheaper to build and get built more quickly. The same goes for gas pipelines. Then they looked at how the energy system would respond. Would we build more power plants? Would there be more natural gas production? Where will that gas go?
The caveats, aside from omitting the bill’s “project certainty” provisions, are that they did not account for policies that support geothermal energy, virtual power plants, advanced transmission technologies, or the ways in which the bill would reduce congestion on the grid — all of which could result in fewer emissions. At the same time, the modeling assumes that all of the data centers that get built between now and 2040 connect to the grid, even though today, many data centers are planning to run on inefficient off-grid natural gas plants. That means this modeling likely underestimates emissions from data centers. (Although the authors did a separate exercise that went deeper into data centers, which I’ll explain shortly.)
The report also limited its analysis to the United States. While the modeling found that liquified natural gas exports would increase by 8% to 15% under BAAJA, the authors did not account for how those exports could affect the energy mix or emissions in the rest of the world.
They found that the bill’s changes to the Clean Water Act and the National Environmental Policy Act would enable more gas pipeline development, which, in isolation, would increase emissions relative to a world without BAAJA. More pipelines means more production of oil and natural gas, which means higher methane and CO2 emissions throughout the fossil supply chain. Under a worst case scenario, they estimate a 4% increase in the amount of new gas capacity, although gas-fired generation as a whole increases by less than 1% in 2040. Even then, emissions would simply be flat compared to current expectations.
“On net, the emissions increases that we see there are outweighed by the emissions benefits that come from the transmission provisions of the bill,” King said.
The report also studied how BAAJA might affect data center emissions. Its “base case” scenario — which includes all the analysis I’ve shared with you so far — assumes data centers will make up about 17% of electricity demand by 2040. That figure already supposes huge growth in data center energy consumption, because data centers only use about 5% of U.S. electricity today.
But what if data center demand grows even faster than that? The authors modeled two additional scenarios to see what would happen if data center electricity demand instead accounted for more than a quarter of U.S. electricity demand in 2040.
While BAAJA would make it easier for data centers to connect to the grid, it also includes ratepayer protection provisions that would make it more expensive to do so — roughly 10% more for a 1 gigawatt data center, Rhodium estimates. Determining whether that will drive developers on-grid or off-grid was beyond the scope of the analysis, so the modelers looked at the two extremes — a world where all additional data center demand hooks up to the grid and one where none of it does.
For the on-grid scenario, whether or not that additional demand is met with mostly gas plants or cleaner sources largely depends on the price of fossil versus clean generation. But even if most of the demand was met by natural gas plants on the grid, emissions would still be 30% lower than if it was met by natural gas plants off the grid, Rhodium found.
And more of the week’s top fights around development.
1. Richland Parish, Louisiana – Gird your loins for the coming fight over the Meta Hyperion data center’s gas pipeline.
2. Spartanburg County, South Carolina – I have one last data center race to tell you to watch on Tuesday: South Carolina’s 4th, on the northern rim of the state.
3. Goodhue County, Minnesota – Google reached a settlement with an environmental group suing to stop its data center in the small southern Minnesota town of Pine Island, resulting in what local press are saying will be the Land of 10,000 Lakes first state-level environmental review of a data center project.
4. Trumbull County, Ohio – Ohio looks like it just got a tad friendlier for data center opponents.
