In 2023, I embarked on a journey with a group of energy policy researchers from Beijing to visit several Chinese coal cities. We wanted to understand the implementation of China’s decarbonization policies in the heartland of coal mining. As we drove into a coal-rich town in western Shanxi Province, the narrow roads were filled with loud rumbling coal trucks. Amid soot-streaked buildings, newer homes housed families who were relocated from areas affected by coal mining subsidence. The town’s existence hinged on coal. Yet, this dependency has an expiration date — the local mines will be depleted in 10 to 15 years.
