Have China’s Emissions Already Peaked?

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.
