Current conditions: Dangerous flash flooding could hit the south-central United States today, with some areas facing the potential for 8 inches of rain in 12 hours • The U.N. is warning countries in Northwest Africa that weather conditions are favorable to locust swarms • Temperatures in parts of Pakistan today will approach 122 degrees Fahrenheit, the global record for April.
After 100 days in office, President Trump has the lowest job approval rating of any president at this point in their tenure in the past 80 years. “Chaos, uncertainty, ‘we don’t know yet.’ These are words I’ve heard more during Donald Trump’s first 100 days back in the White House than I’ve heard at any other time as a reporter,” my colleague Emily Pontecorvo writes for Heatmap (something I can vouch for, too). From his slashing of the federal workforce to regulatory rollbacks to his unpopular tariffs and targeted attacks on “climate” in every form, Trump is reshaping the economic and policy environment from the top down.
Emily put together five charts yesterday to help visualize the impact of Trump’s second term to date. Some of the most striking takeaways include:
You can read Emily’s full story — with charts! — here.
Emily also reviewed the first draft of the House Transportation and Infrastructure Committee’s budget, which was released on Tuesday. “Remember, the name of the game for Republicans is to find ways to pay for Trump’s long list of tax cuts,” she writes. In the proposed budget, the Transportation Committee puts forward one new revenue-generating program — an annual fee of $200 on electric vehicles and $20 on conventional gas-powered cars to pay into the Highway Trust Fund — plus a list of “rescissions” of unobligated funds from the Inflation Reduction Act. That list includes efforts to claw back more than $1.7 billion for improving the efficiency of government buildings, as well as whatever remains of the $3.2 billion allocated to the Federal Highway Administration to promote improved walkability and transportation access, along with five other key IRA grant programs. But “this is just a first pass,” Emily reminds us, “and this is all subject to change.”
COP30 President André Corrêa do Lago warned that as the U.S. retreats from the fight against global warming, it will become increasingly difficult to persuade other countries to commit to the energy transition. Speaking at the BloombergNEF Summit in New York, approximately six months out from COP30 in Belém, Brazil, Corrêa do Lago stressed that “There is obviously some that say ‘God, how am I going to convince my people to lower emissions when the richest country isn’t doing the same.’”
It is unclear what sort of delegation the U.S. will send to COP30, given the Trump administration’s severing of global climate research and its exit from the Paris Climate Agreement. China, meanwhile, has announced its intention to commit to stricter climate goals ahead of the November meetings in Brazil. “China is demonstrating an absolute conviction that it's the right way to go,’’ Corrêa do Lago said.
Ford’s director of electrified propulsion engineering announced on LinkedIn that the company has made a significant breakthrough in battery technology, the Detroit Free Press reports. “This isn’t just a lab experiment,” the director, Charles Poon, wrote. “We’re actively working to scale [Lithium Manganese Rich] cell chemistry and integrate them into our future vehicle lineup within this decade.” LMR replaces commonly used nickel and cobalt with manganese, which Poon says costs less and helps approach “true cost parity with gasoline vehicles” as well as “higher energy density” that “translates to greater range, allowing our customers to go further on a single charge.”
Many companies have made advances in LMR, which is not a new technology, but Ford clarified in comments to the Free Press that it has overcome some of the technical challenges of LMR, like voltage decay, while “not sacrificing energy density.” Still, Ford was short on details, leaving some skeptical of the supposed revolution in battery technology. Sam Fiorani, vice president of global vehicle forecasting at AutoForecast Solutions, thinks Ford “found a workaround, but this is far from a breakthrough,” according to Autoevolution. “However, such efforts are welcome as carmakers try to push the envelope of current battery technology.”
The largest bank in Canada, the Royal Bank of Canada, announced on Tuesday that it is “retiring” its sustainable finance goals and will not disclose its findings on how its high-carbon energy financing compares with its low-carbon energy financing, according to the Canadian Press. Per RBC, the move is due to regulatory changes, including Canada’s Competition Act, which was designed to prevent corporate greenwashing by requiring climate reporting to be backed by internationally recognized measures, The Globe and Mail explains.
By backing off its target, RBC is abandoning a $500 billion commitment to sustainable finance this year. The bank previously exited the Net-Zero Banking Alliance, a global initiative spearheaded by Mark Carney, who was elected to a term as prime minister earlier this week. While “campaigners worry banks are seizing on a shift in the political climate, particularly under U.S. President Donald Trump, to dilute commitments to act quickly on decarbonising their portfolios” — per Reuters — RBC said it has not abandoned its intentions of addressing climate change and that it should be considered the “bank of choice” for the energy transition.
A startup in Switzerland is installing removable solar panels in the unused space between train tracks. The company, Sun-Ways, says that if it installs panels across the entire 3,300 miles of the Swiss rail network, it could generate one billion kilowatt-hours of solar power per year, equivalent to approximately 2% of the nation’s electricity needs.

The data center boom is everywhere you look in U.S. economic and emissions data.
This is an edition of Heatmap Daily, an evening review of the day’s news written by our executive editor. Sign up for it here.
It isn’t exactly a new thought, but I’ve been struck recently by how many trends in America’s economic and environmental data are fundamentally about the data center boom and the return of electricity demand:
First, the Energy Information Administration reported this week that U.S. emissions grew by more than 2% last year, driven by surging electricity demand and an increase in coal-fired generation. What caused that higher power demand? New factories and data centers — as well as record summertime cooling demand.
Second, many of the new factories driving that higher power demand are themselves producing goods that are … let’s say … data center-adjacent. There are the enormous new semiconductor fabs, of course. But Ford and General Motors have also set up new production lines (or repurposed old ones) to manufacture grid-scale batteries to meet power demand.
Third, take a look at the recent U.S. spending on private non-residential construction — in other words, everything American companies are building that is not houses, condos, or apartments.
The construction industry’s spent almost $60 billion on data centers over the past year, which is more than it spent on all other office buildings combined (and more than it spent building warehouses, too). Just a handful of categories — data centers, power plants, electricity infrastructure, and certain kinds of electronics manufacturing — now make up a third of all U.S. private non-residential construction investment. They’ve never made up such a large share of construction spending since data collection began in 2014.
As The New York Times recently noted, the American economy is unusually dependent on the American stock market right now — and the stock market is unusually dependent on artificial intelligence. This week, investors started to balk at the enormous spending hyperscalers are planning to keep building out the AI boom; Alphabet’s shares dropped 8% this week after it boosted its planned 2026 capital expenditure and signaled 2027 will be even bigger. If the data center boom started to slow down in earnest, then more than just that budget will change.
Speaking of which, my colleague Emily Pontecorvo wrote earlier this week about how many businesses are struggling to even estimate their carbon emissions from artificial intelligence. The carbon accounting startup Watershed recently unveiled a new formula to help companies get a sense of their AI-related emissions.
But even that formula is still limited by the amount of data hyperscalers publish — and they don’t publish that much. Google, for instance, is the only AI company that has (laudably) provided estimates of its emissions on a per-prompt basis. Yet no company has published its per-token emissions, or how emissions sync up with particular models or regions.
So Emily asked Google: Why aren’t you — or any other model provider — disclosing this kind of data yet?
The tech company didn’t get back to us until after we’d published Emily’s story. But its response was interesting enough that I wanted to quote some of it here.
The problem is “industry consensus,” Cooper Elsworth, a Google spokesperson, told us. “There is currently very little consensus on how to comprehensively and fairly measure the serving environmental impact of generative AI (such as text generation),” he wrote. “Without standardized, ‘apples-to-apples’ frameworks, it is difficult to compare different providers accurately.”
That’s partly because energy use — and emissions data — can vary from site to site and depend on “custom-built hardware, software compilers, and advanced inference techniques.” And he claimed Google doesn’t always have the measurement hardware in place to provide such specific estimates: “Providing precise, repeatable data requires highly advanced measurement infrastructure,” he said. “For example, software-based energy monitoring tools often suffer from sampling biases. For our study, we had to step away from top-down averages and directly measure actual energy at the physical power supply unit (PSU) level across our deployed fleet. Not all providers have the telemetry or data sets required to benchmark their operations at this level of granularity.”
Read Emily’s story to understand the other reasons why estimating — or even “guesstimating” — AI-related carbon emissions is so challenging.
A conversation with Emma Uridge of the Kansas Health Institute.
This week’s conversation is with Emma Uridge, analyst with the Kansas Health Institute. Uridge spent copious hours analyzing state and local laws on data center development to best understand how policymakers are responding to the potential environmental public health impacts of large AI infrastructure, including power and water. The report, which came out this week, also goes in depth into those health impacts. I reached out to her to discuss what she sees as must-watch territory for our readers on this emerging policy arena.
Our conversation was lightly edited for clarity.
What is actually being done on policy when it comes to data centers — beyond moratoria of course?
So first I’d like to just talk about the point of moratoria. It’s helpful to talk about how these policies emerge in the first place. One area where moratoria are helpful is when a data center is proposed but the county has no approach for how they’d like to potentially regulate them. That’s temporary, most of the time. It lets local governments conduct research on the various impacts and also negotiate community benefits, ones that can mitigate any potential negative impacts — like Lancaster Pennsylvania, which instituted a community benefit agreement that maximized the potential benefits of development while mitigating what large data centers can do. That agreement looked at capping municipal water use at 20,000 gallons per day and requiring 100% clean energy. It had financial penalties for non-compliance. The company also committed $20 million to their local economic development and clean energy fund. There are ways to negotiate with developers.
We also see amendments to existing zoning. Data center proposals are increasingly popping up in rural areas, many of which are unzoned, so there’s no way a county can negotiate unless there’s a moratorium in place.
Other policy solutions include different performance standards or requiring on-site renewable energy, like what Jefferson County, Missouri, looked at. Also setback requirements, mandatory noise buffers, ending by-right zoning.
Where are local governments getting ideas for regulating data centers?
A lot of the technical information comes from developers. That can in cases be seen as a biased source of information. I wouldn’t say there’s a dedicated group providing assistance to local governments when a project is proposed — which is a similar story to wind industry development, where we have only a handful of consultants who provide technical advice. It can be really helpful to get a multi-disciplinary approach to hearing information. It can be helpful to have the utility commission, public health folks, those in academia, as well as the developer.
As of right now, especially in rural areas, local governments have a hard task of balancing pushback while getting the most accurate, evidence-based, neutral information to make decisions. That balance can be contentious.
What is the federal government doing on data center policy? How is the Trump administration approaching it?
A few things there. In the early days, the drive was for AI expansion and to be competitive with foreign adversaries. Now due to the amount of public pushback in red and blue localities and a more cautious approach.
I’m not seeing a lot of actual policy movement at this time.
I know the EPA is looking at the chemicals used in cooling data centers because when that water is cycled through the system, some of it is discharged into the water system, so they’re looking at the Toxic Substances and Control Act for monitoring that.
How much of an impact does this minimal federal role have on industry behavior?
Y’know, this isn’t specific to data centers. This is true for all kinds of large-scale development: there’s a need to require some sort of federal monitoring and regulation.
That’s where I see an emerging role for public health. At the federal level, there could be policy movement towards requiring some sort of environmental monitoring at data centers to make sure they’re operating responsibility. Looking at specific water use relative to water availability and what happens when there’s a time of severe, persistent drought. With air quality too — we’ve seen areas where the grid isn’t as reliable so their diesel generators are kicking on more and affecting air quality for residents.
We’re just not seeing all of that right now. We need corporate disclosure.
What do you see as the most important public health impacts from data center development?
It varies by localities. The most discussed obviously is water usage. One thing I’d note about my conversations with folks enthusiastic around emerging tech is, there are still questions that need to be asked about the capacity of localities to support a data center. Like a small town in Kansas may only be using 40% of their water for their utility needs. If a data center came online, how much of that water goes to the data center?
One area underexplored within the public health discipline is energy poverty and energy security. The ability of a household to meet the needs of everything energy provides in our lives. It’s known we have an aging electric grid but we’re not talking enough about large-scale blackouts when the grid is not sufficient to support some of these new data centers.
Plus more of the week’s big development fights.
1. Laramie County, Wyoming — Meta is fighting the fine it received in the Cheyenne data center water pollution controversy, and the conflict between the tech giant and the city’s small board of public utilities is continuing to spill out into the public.
2. Niagara County, New York — This county just rejected a solar project’s highway work permits in a show of retaliation against the state’s Office of Renewable Energy Siting.
3. Barron County, Wisconsin — The anti-solar protest is the new campaign stop in deep red Wisconsin.
4. Chesapeake, Virginia — A large battery storage project on the Virginia coastline is on the rocks amidst rampant local opposition.
5. Lewis County, West Virginia — West Virginia is now a key battleground in the fight over transmission, as a line spanning all of West Virginia and Maryland — and cutting through Data Center Alley in Virginia — causes compounding consternation.
