Now can we talk about the hard stuff?

Today is Methane Day at COP28 in Dubai, and there has been a slew of new commitments to wrangle the highly potent, short-lived greenhouse gas:
➢ The Biden administration finalized the strongest-ever federal regulations in the U.S. covering the methane that leaks from existing oil and gas wells, plus tightened rules for new wells. The Environmental Protection Agency expects to achieve a nearly 80% reduction in emissions compared to a world without the rules.
➢ Canada is also expected to announce new methane regulations.
➢ Turkmenistan and Kazakhstan — home to some of the biggest methane leaks from oil and gas operations in recent years — joined a global pledge to reduce methane emissions by 30% this decade. If the pledge is successful, it could eliminate more than 0.2 degrees Celsius of warming by 2050.
➢ Nearly 50 oil and gas companies signed onto a “decarbonization charter,” committing to reduce the ratio of methane released to fuels produced to 0.2% by 2030, and to capture the gas instead of flaring it. For reference, the current methane intensity of U.S. oil and gas production is about 2.5%.
➢ A new partnership between Bloomberg Philanthropies, the United Nations Environment Program, the Environmental Defense Fund, the International Energy Agency, and RMI will use satellite data and analysis of leaks to hold companies and governments — in particular the oil and gas charter members — to their pledges.
➢ All of this follows a new methane deal from the European Union to reduce methane leaks at home and, by 2030, require companies importing oil and gas to the EU to meet a standard for emissions associated with their product.
➢ China also recently released a methane action plan, and agreed for the first time to include non-carbon dioxide greenhouse gases like methane in its emissions targets. The country is a co-host of the Summit on Methane and Other Non-CO2 Greenhouse Gases at COP28 today.
This is not the first time many of these groups have pledged to address methane, which leaks into the atmosphere from oil and gas infrastructure, coal mines, landfills, and farms. But taken together, today’s actions bring more ambition, transparency, and accountability to the task.
During a press briefing on Friday morning, U.S. Climate Envoy John Kerry told reporters that reducing methane emissions is the “easiest, quickest, cheapest, simplest” way to fight climate change. There’s two reasons for that. First, since methane begins breaking down in the atmosphere after about a decade (unlike CO2, which can last hundreds of years), cutting methane emissions will reduce warming significantly in the near-term. Second, experts say that reducing leaks from oil and gas infrastructure is both technologically doable and cost-effective. “It’s not complicated technology,” Kerry said. “It’s mostly plumbing.”
But for an issue that’s so easy to address, the scourge on methane has sucked up a lot of oxygen in the climate conversation over the past five years, especially in the U.S. Writing about “the quickest way to slow warming” has become a tired cliché for climate journalists, me included. Ever since scientists at the Environmental Defense Fund reported that methane emissions from oil and gas production were being severely undercounted in 2018, attention to methane by environmental groups, researchers, the U.S. government, and even the oil and gas industry has steadily risen. But so have methane emissions, according to some estimates.

The Obama administration first tried to regulate emissions from existing wells and tighten standards for new wells in 2016. Then the industry sued. Trump rolled back the rules. The Biden administration tried again in 2021, proposing new rules during COP26 in Glasgow and spearheading the Global Methane Pledge. One year later, during COP27, the Biden administration issued yet another proposal to “update, strengthen, and expand on” the original. Now that the rules are finalized, some won’t even go into effect for another two years so that states have time to develop plans to adhere to the regulations on existing wells.
It does look like this moment is different — that this could be a real turning point. Engineers have made great advances in methane detection technology. Satellites, drones, and handheld detectors have turned up “super-emitters,” astoundingly large leaks from oil and gas operations all over the world that would have otherwise gone unnoticed and unaddressed.
During the Friday morning press briefing, billionaire philanthropist Michael Bloomberg, who is putting $40 million toward the new watchdog effort to hold companies accountable, promised this would not be “just another announcement.” He pointed to his Beyond Coal campaign, which successfully shut down 70% of U.S. coal plants over the past five years. Inger Andersen, executive director of the United Nations Environment Program, said there will finally be transparency. “Without transparency, all we have is pledges,” she said.
So the world may finally be moving in concert to address methane, this lowest hanging fruit, this bare minimum, this fastest way to slow warming. Well, la-di-da. Now that there’s some consensus on methane, will there be more room to talk about the harder stuff? Like, the root cause of climate change? Like, ending the use of oil and gas, and — god help us — coal?
The U.S. committed today to finally phasing out the dirtiest fossil fuel, but other countries — notably India — are still digging in their heels. Andersen mentioned a report the UNEP released in November, which found that the majority of oil and gas producers plan to increase their production between now and 2030, and some until 2050.
“The addiction to fossil fuels still has its claws deep in many nations,” the report says. “Governments are planning to produce, and the world is planning to consume, over double the amount of fossil fuels in 2030 than is consistent with the pathway to limiting global temperature rise to 1.5°C. These plans throw the global energy transition into question. They throw humanity’s future into question.”
Yes, cutting methane emissions from oil and gas operations will stave off worse climate impacts, buying the world some time as it tackles the much harder challenge of phasing out fossil fuels. But it also gives fossil fuel companies a new defensive weapon as we enter this next stage of climate action. They will be able to say their products are cleaner — perhaps even that we should thank them for helping the world avoid 0.2 degrees C of warming while their plans “throw humanity’s future into question.” To make progress beyond methane, we’ll need to get from pledges to action a lot more quickly.

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.
