China's total CO2 emissions went flat and slowly started declining almost two years ago, but you probably wouldn't know it from reading the news about how its pipeline of coal power plant projects surged to a record high in 2025.

Similarly, recent data shows that China's coal power output fell by 1% in 2025, even as it built more coal plants than it had in a decade.

These kinds of conundrums are typical for China, with its complex interaction of economic forces and top-down state planning. But once you understand what's driving them, it all makes sense—just not a Western economic kind of sense.

To help us untangle this picture, we welcome back Lauri Myllyvirta, co-founder and lead analyst at the Centre for Research on Energy and Clean Air (CREA), who last joined us in Episode #138, all the way back in 2021. We were overdue for an update.

In this episode, we dig into this coal conundrum—why China added 78 GW of new coal capacity in 2025, more than India built in an entire decade, even as customers pay $14 billion a year in capacity payments to coal plants that may not even run. We look at the 315 GW of solar and 120 GW of wind China added last year, and how 75 GW of new storage is helping to displace coal power. And we discuss why China's clean energy investments now make up more than a third of its GDP growth—without them, 2025 growth would have been 3.5% instead of 5%.

Although its fleet of coal power plants continues to grow, there is good news here. Because as the largest energy consumer in the world, China's declining emissions mean emissions are declining globally.
