Have China’s Emissions Already Peaked?

Rob and Jesse talk all things solar, steel, and cement with CREA’s Lauri Myllyvirta.

China’s greenhouse gas emissions were essentially flat this year — or they recorded a tiny increase, according to a recent report from the Centre for Research on Energy and Clean Air, or CREA. A third of experts surveyed by the report believe that its coal emissions have peaked. Has the world’s No. 1 emitter of carbon pollution now turned a corner on climate change?

Lauri Myllyvirta is the co-founder and lead analyst at CREA, an independent research organization focused on air pollution and headquartered in Finland. Myllyvirta has worked on climate policy, pollution, and energy issues in Asia for the past decade, and he lived in Beijing from 2015 to 2019.

On this week’s episode of Shift Key, Rob and Jesse talk with Lauri about whether China’s emissions have peaked, why the country is still building so much coal power (along with gobs of solar and wind), and the energy-intensive shift that its economy has taken in the past five years. Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

Here is an excerpt from our conversation:

Jesse Jenkins: So there’s sort of two key variables here. And we hit both those: the growth rate in new clean energy supplies, particularly in the electricity sector, and then the pace of demand growth. And this has been the story globally, the argument that we actually haven’t really seen any energy transition, only energy addition, right? We’re adding enough new clean energy, maybe, to meet growth, but not actually to drive down emissions, which would require us to exceed the growth rate and demand, right? So we can eat into the market share of existing fossil generation.

And that’s sort of the fundamental equation in China as well, right? Is if demand is growing rapidly, more rapidly than, clean electricity additions, emissions go up. And if the opposite is true, emissions go down. There’s also, it seems like, some evidence that the economy itself is slowing, or at least going through a bit of a structural change, right? So still growing, but not growing, perhaps, at the target rates that government has set. I think the expectations for this year, if I’m not mistaken, are under 5% growth, maybe 4.5% to 4.7% — so, you know, in U.S. terms, that’s still quite rapid, but in Chinese terms, a bit slower than the goal. And part of that is a slowdown in the construction industry — is that right? — which is another major driver of emissions due to cement consumption and steel consumption.

Lauri Myllyvirta: Yeah, so I’m a bit allergic to talking about the economy as a whole — you know, “the economy” is slowing down, or “the economy” is speeding up. Because the economy is, of course, made up of a lot of different sectors, and in order to understand energy demand, those sectors are not created equal. So if you have a 5% GDP growth that comes from service industries, from consumer-facing industries, that can mean much less than 5% growth in energy demand. And that’s what China was seeing until the Covid period.

China was actually making a pretty big deal out of improving the energy, or reducing the energy-intensity of the economy. And that’s what stopped in 2020. So since 2020, there has been essentially no reduction in the energy intensity, energy consumption, and GDP has grown at the same rate. And when you consider the fact that there is a lot of technical improvement still going on, different processes are getting more energy efficient, then that means that the structure of the economy has, in fact, gotten more energy-intensive. And that’s the key concern. The less than 5% growth now is driving faster growth in total energy demand than the 6%, even 7% growth was during the previous decade.

Trump’s Tax Law Is Slowing Down Projects and Piling Up Legal Work

With construction deadlines approaching, developers still aren’t sure how to comply with the new rules.

Certainty, certainty, certainty — three things that are of paramount importance for anyone making an investment decision. There’s little of it to be found in the renewable energy business these days.

The main vectors of uncertainty are obvious enough — whipsawing trade policy, protean administrative hostility toward wind, a long-awaited summit with China that appears to have done nothing to resolve the war with Iran. But there’s still one big “known unknown” — rules governing how companies are allowed to interact with “prohibited foreign entities,” which remain unwritten nearly a year after the One Big Beautiful Bill Act slapped them on just about every remaining clean energy tax credit.

The Department of Energy Is Spending a Tiny Fraction of Its Money

Deep cuts to the department have left each staffer with a huge amount of money to manage.

The Department of Energy has an enviable problem: It has more money than it can spend.

DOE disbursed just 2% of its total budgetary resources in fiscal year 2025, according to a report released earlier this year from the EFI Foundation, a nonprofit that tracks innovations in energy. That figure is far lower than the 38% of funds it distributed the year prior.

How Trump’s Speed-to-Power Push for Data Centers Could Backfire

Will moving fast and breaking air permits exacerbate tensions with locals?

The Trump administration is trying to ease data centers’ power permitting burden. It’s likely to speed things up. Whether it’ll kick up more dust for the industry is literally up in the air.

On Tuesday, the EPA proposed a rule change that would let developers of all stripes start certain kinds of construction before getting a historically necessary permit under the Clean Air Act. Right now this document known as a New Source Review has long been required before you can start building anything that will release significant levels of air pollutants – from factories to natural gas plants. If EPA finalizes this rule, it will mean companies can do lots of work before the actual emitting object (say, a gas turbine) is installed, down to pouring concrete for cement pads.
