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.

Plus, the Trump administration appointed a new “beacon of rational thought.”
We got a look at another major tech company’s latest energy and carbon emissions data — and it’s a doozy. On Wednesday, Microsoft released its annual sustainability report, giving us another year’s worth of energy and emissions data for a company that Heatmap’s annual insiders poll once judged to be one of the best hyperscalers for climate change.
The headline: Microsoft’s climate pollution surged last year. Its carbon emissions increased 25% year-over-year, the biggest single-year rise since at least the pandemic. The company emitted the equivalent of 21 million tons of carbon dioxide in 2025, under standard measurement methods. (It emitted slightly less under its own bespoke measurement system, which counts fuel credits and customer energy use differently.)
Electricity, which the company is buying in larger amounts than ever before to power AI data centers, is driving a good share of that increase. In 2024, carbon pollution produced by generating electricity (as well as from making chilled water and steam) was responsible for 2% of Microsoft’s total corporate carbon footprint. In 2025, that same category made up 13% of its overall emissions. The company’s power use rose by more than 24% over the same period.
That means Microsoft’s power use isn’t rising as fast as other companies’. Google’s most recent sustainability report said its own electricity consumption leapt 37% during the same period.
The report suggests, too, that Microsoft is increasingly wary of local fights over data center development — and how water has come to play an outsize role in those battles. The company reports that 2025 was the first year ever that it “replenished” more water on global scales than it withdrew. But “the next phase of our work is increasingly local,” write Brad Smith, the company’s vice chair and president, and Melanie Nakagawa, its chief sustainability officer. That line is clearly in reference to water, specifically — Smith and Nakagawa add that the company hopes to “restore more water to the watersheds where we operate than we withdraw” — but it could also cover the widespread local opposition to data centers that has exploded over the same period.
There’s one more thing to flag about this report: Although it just came out, it covers Microsoft’s 2025 fiscal year, which began in July 2024 and ended more than a year ago. That means it’s inherently an out-of-date view — it shows us what Redmond was doing as the AI and data center boom got underway, but not what it’s doing now. We’ve known for some time that the company is struggling to meet booming AI power demand while maintaining its power commitments; it paused carbon removal buying in April and revised its own clean energy commitments in May.
I should add that Microsoft would prefer that we look at other numbers in the report. First, under its in-house measurement scheme, the company says it released only 20 million tons of carbon pollution over the past year, a figure that appears in its top-line charts. Second, Microsoft estimates that it would have done even more harm to the climate — producing 34 million tons of climate emissions — if not for its corporate policies of buying zero-carbon electricity, using renewable fuels, and improving the energy efficiency and carbon footprint of its XBox game consoles and Surface tablets.
We asked Microsoft for a follow-up interview, but unfortunately they didn’t make anyone available. I’ll be back tomorrow to look at Microsoft’s report in context with other hyperscalers.
Speaking of a sudden rise in gaseous emissions, the Trump administration today named a new leader of the federal government’s marquee in-house climate research office, the U.S. Global Change Research Program. Per Politico, the new top dog is Matthew Wielicki, a UCLA PhD who (1) has a Substack, (2) refers to himself (in the third person) as a “beacon of rational thought” and “professor in exile” on said Substack, and (3) has suggested on X that climate change belongs in the “Department of Imaginary Problems.”
What can I say? Back during President Trump’s first term, his administration tried to bury the publication of the National Climate Assessment by dumping it on a holiday weekend. Now it seems to have taken another strategy. All I can say is, Dr. Wielicki, from one beacon of rational thought to another: I look forward to following your work.
Water pollution in Wyoming has big implications for the future of data center development.
Did a Meta data center introduce a rare, dangerous bacteria into the sewers system of Wyoming’s capitol city? It’s an environmental pollution mystery with an answer that could decide the future of American AI infrastructure development.
Our drama begins in Cheyenne, Wyoming, where the city’s board of public utilities just wrapped up a lengthy investigation into the presence of Cupriavidus gilardii, a potentially lethal bacteria resistant to heavy metals, in the city’s wastewater treatment systems. Apparently, in February, board staff detected the contamination and shut off public access to the city’s water reuse system, a supply of treated non-potable water fed with treated wastewater and used for lawns, athletic fields, and other green spaces. Officials were worried that spraying this water could release into the environment a bacteria found to cause fatal health outcomes in immunocompromised or elderly people who are infected by it.
The board then identified a culprit – Goat Systems LLC, a Delaware-registered firm without a website Meta tasked with overseeing its large $800 million hyperscale project in Cheyenne dubbed Project Cosmo. Goat Systems lost its wastewater disposal permit. The board plans to also fine Goat Systems for violating city code “along with additional fees for our remediation efforts,” board public affairs coordinator Erin Lamb told me in an email. (The only person publicly affiliated with Goat Systems is Pamela Gregorski, an employee for a company that specializes in creating LLCs. Gregorski, who is linked to other LLCs handling Meta projects across the country, did not reply to requests for comment.)
In public comments and statements to me, the board linked the bacteria to water used to flush the Meta data center’s closed-loop cooling system so debris could be removed before the facility was operational. “We were able to connect the Meta data center campus to this through sampling their site,” Lamb said.
This finding led Cheyenne to also indefinitely ban data center projects in the city from ever disposing of “fill-and-flush water” in the sewer system again.
Meta has not denied contamination was found by the city, but says repeated sampling at its project site failed to come up with any evidence confirming they were the source. One can imagine a scenario where the data center and its design played no role in this bacteria showing up, or that city officials erroneously tagged the tech company with responsibility at a time when they’re dealing with political troubles already.
But what is happening in Cheyenne, first reported last week by Wyoming local press, will have consequences for the future of AI infrastructure whether or not Meta was actually even responsible. Right now, all over the country, tech companies are failing to get permits for their data centers because people are worried about water use. These closed-loop data center designs are supposed to address those concerns, letting large hyperscalers contain, cycle, and reuse the water they use for months or even years. A story like this gaining traction in public discourse around data centers will inevitably damage the sector’s public image unless rectified – and fast.
Cheyenne’s claims about the Meta data center being responsible for the bacteria have already metastasized on social media, disseminated through channels often cited by data center opponents on the ground elsewhere in the country. “REPORT: ‘RARE’ BACTERIA DISCHARGED INTO WYOMING WATERSHED LINKED TO DATA CENTER,” reads one post by a Facebook user Izzy Bella that has been shared more than 2,600 times. “Think of this the next time you hear blatant greenwashed lies like ‘closed loop cooling.” This post has been shared by major anti-data center groups on Facebook, including Pennsylvania Data Center Resistance, a social media page for organizing against projects in the Keystone State.
Going solely off what happened in Wyoming, some in the state are concerned the process of cleaning these loops before opening a data center can produce some nasty byproducts. Dr. Jonathan Brand, a civil engineering professor at University of Wyoming, has been studying the data center buildout in Wyoming for years, watching what’s happened in Cheyenne closely, and like me has way more questions than answers.
Usually, Brand said, a company using water in metal-intensive industrial applications – think a metal plating facility – has to test that fluid before it’s dumped into a municipal sewer system. The chain of events spelled out by the board left him “guessing that didn’t happen here,” and he’s worried the bacteria formed within whatever petri dish-like environment was created inside the network of looping pipes before it was flushed.
“The bacterium was the canary they saw, but you could have a lot of residual metals, which is not something we normally test for at a wastewater plant,” he said. “What else was in that discharge? Nobody else has let us know that and they’re probably not going to.”
City officials claim the water was tested before it entered the sewer and was missed, but there’s a trust deficit between locals and the government on what happened. Little of this information was public until a few weeks ago. Cheyenne residents first learned trouble was afoot on June 26, when the board posted a press release “reminding all residential, commercial, and industrial customers that the discharge of hazardous substances into the sanitary sewer system is strictly prohibited.” Nothing was included about data centers at all; all the board said was that the bacteria was dumped by “an industrial user within the system.”
Then Exie Brown, a Cheyenne resident and GOP candidate for state house, blasted a press release out on social media declaring “a credible source with knowledge of the [board] investigation and sampling” told him the “industrial user” was a data center.
I reached out to Brown asking how he learned about this. His answers were cryptic. “I was given a piece of paper with that name of a bacteria on it,” he told me over the phone, declining to name the “very credible source” who told him about the contamination. “That it was released into our waste water system, that it came from a data center, that it was Meta, that they found out in February, and I needed to check into this.” When I asked why the piece of paper, he replied: “Because they [the source] wanted to keep this quiet. Off the phones and stuff.”
City officials deny any malintentions behind the delay and claim they’re learning about all of this at the same pace as the average resident. “We learned here a week or so ago,” Cheyenne mayor Patrick Collins told me in an interview. He added this wouldn’t have stirred as much interest “had it been something else,” referencing the fact it was from a data center.
“As I understand it, the contractor that was building the site was flushing out a closed-loop cooling system, and when they tested the water everything seemed to be fine, but when it was released into our system, bacteria had grown and was released into our wastewater treatment,” Collins said. “It just happened to be a data center. It’s an unfortunate and highly regrettable situation.”
The mayor acknowledged this contamination will make it “a little tougher” to argue for more data centers in the city. There are currently 10 operational data centers in Cheyenne and surrounding Laramie County, according to estimates from pro-business group Cheyenne LEADS, which has said five projects are under construction – including the Meta facility – and at least nine others are “in various stages of planning or due diligence.”
On Monday, the Cheyenne city council will vote on whether to annex land owned by various nearby property owners for more data center deals, including parcels owned by the family of U.S. Senator Cynthia Lummis. Before this event, Cheyenne was incredibly resistant to the anti-data center backlash, handily rejecting proposals to pause development.
Collins thinks Cheyenne will still be open to the tech sector. But the bacteria changed things. “I recognize there’s going to be challenges as we move forward. It’s something we’re going to have to look into. This was a regrettable situation that happened.”
We will see more transparency soon from the Cheyenne city government about the contamination. The board tells me it’s planning a press conference next week where Lamb told me “more information will be made available.”
Francis Brennan, a public affairs manager in the company’s strategic response division, provided me with a statement from an unnamed “Meta spokesperson” claiming that Fortis – the construction company hired by Meta and Goat Systems LLC – was directly handling water disposal on site. After the board “shared that it found a substance in the city’s wastewater” the construction company “began hauling it offsite.” Meta claimed Fortis has not been able to corroborate the presence of this bacteria in comparable water samples.
“Meta is committed to being a good neighbor in Cheyenne, including through the protection of local water resources, and will continue encouraging collaboration between Fortis and the board until this situation is revoked,” the statement read. Meta declined to answer follow-up questions..
Fortis confirmed they were responsible for dumping water on site when the contamination was discovered. They stated they’ve been unable to confirm the presence of the bacteria. In a statement provided to me, the company said: “Immediately upon learning of the issue, we stopped discharging water into the city’s wastewater system. We have since engaged in a thorough investigation that has included ongoing repeat testing by independent environmental specialists and have found no trace of the substance.”
A conversation with Ross Marchard of the Taxpayers Protection Alliance
This week’s conversation is with Ross Marchard, executive director for the Taxpayers Protection Alliance, a center-right advocacy group that focuses on what it sees are onerous policies potentially hindering responsible collection and use of tax dollars. TPA’s position on AI clearly skews pro-free market, as they’ve recently defended Anthropic from Trump administration attacks. TPA also recently took on the mantle of defending data centers from noise complaints, publishing a paper on Tuesday “debunking myths about data centers being excessively noisy.” The paper references various analyses of data centers by state legislators and local regulators to argue that claims the sector is generally noisy are false.
I asked TPA’s executive director to chat with me about why and how the organization will try to quell these fears. The conversation was really interesting so I decided to share it with you in full, sans light editing for clarity and consistency.
What prompted you to write this report?
Obviously, data center projects have been getting so much media attention. With that attention there’s an outsized share of misinformation in coverage of these data center projects, and politicians have irresponsibly spread this misinformation to try and enact moratoria and heavy-handed restrictions on these projects
TPA wanted to get the truth out. Make sure local residents living alongside these data centers have access to all the information they need. Make sure this misinformation is countered.
Before we get into the noise aspect, how is this focusing on “taxpayer protection”?
Sure, well, great case in point is Loudon County. They’ve embraced data centers and look what’s happened, they take in a billion dollars a year in revenue from these data centers and it’s allowed them to lower property taxes. You see a wider pattern across communities. They rake in a tremendous amount of tax revenue and increasingly common well-paying jobs, six-figure blue collar jobs that are a direct result of allowing data centers into communities.
I know you’re based in D.C., near Loudon County. I went to a data center in Sterling, Virginia, in that county, and it was especially noisy. Sort of a worst case scenario on that. Your report talks about misinformation around noise and data center – where is the misinformation happening on this issue?
We saw a recent court case out of New Jersey that alleges data centers generally are as loud as helicopters. Look, anything is possible for a particular project. But what we can say based on our analysis of the data, studies and sound impact assessments, and analyses by state and local governments is that this isn’t the case for the vast majority of data centers.
No use of land is going to be sound-free. I live right on Georgia Avenue in Washington, D.C., so I know noise. But everything we analyzed showed data centers and energy generation on site are going to make some noise but not enough to be harmful to human health. Often it’s no louder than the typical conversation between two people.
Speaking of Loudon County, though, I can point to an example of a project I myself visited that was I’m sure welcomed at first on tax revenue grounds. Now people seem to regret that decision.
As someone trying to address those who are concerned, is it helpful for you to really just call this concern rooted in misinformation? Is this really going to be potent when projects like the one in Sterling exist?
First and foremost, it’s very important to listen to people and their concerns. If folks are living alongside a data center and say they’re hearing loud noises, that warrants investigation. But it’s also important to look at the full array of evidence and we’ve done that. So far, it does not appear to be the case based on the overwhelming amount of evidence that is publicly available that data centers use a lot of water, use inordinate amounts of electricity, or are loud in a way that disrupts human health.
What do you think the policy solutions are to address these noise concerns? How do you listen to people, without going into overgeneralization, as you put it?
People tend to point out the loudest data centers are the ones with on site energy generation. If you ask the operators of data centers and the companies building data centers, they’ll tell you more often than not the reason they’re putting generation on site because the utility permitting process takes far too long. That’s the result not necessarily of utility regulations but state regulations foisted upon utilities. So you have to look at everything from state regulation to grid operation regulation. If you make the process easier for data centers to get hooked up to the grid, you’ll see less on site energy generation, and a lot of the noise complaints will go away.
So from your standpoint, a solution to the noise complaint is that it should be easier to hook up to the grid?
Yes. If you allow data centers to get hooked up to the grid, you’ll see fewer diesel generators and that’ll mean fewer noise complaints.
Now, I want to be clear, the vast majority of data centers with noise complaints – those are usually because of on-site energy generation – are not unduly noisy. If you want to cut down on those complaints, what makes the most sense is to make it easier for data centers to hook up.
Fun question to close: what was the last song you listened to?
“Yellow” by Coldplay.
Are you listening to “Yellow” while you’re writing about data centers?
I listen to the song sometimes when I’m writing about data centers. It’s also a very good somber reflection song, which is a pretty common sentiment amongst millennials.
