China's engineering-first climate plan: can mega projects cut emissions?

A new analysis of China's infrastructure push asks whether Beijing can build its way out of climate change. The discussion points to satellite data showing a rate has fallen by nearly 42 per cent in the last year, although the available transcript does not specify which rate. It also sets out the scale of China's construction programme, from dams and solar farms to a vast high-speed rail network, and asks whether an engineering-first approach can help the country deal with global warming.

The programme notes that China has built mega cities and mega projects that have transformed the country. Those schemes have also produced mega emissions, the largest in the world. At the same time, China dominates the global green technology sector. The discussion frames Beijing's thinking around three C's: capitalism, construction and control.

A central argument is that China operates as an engineering state. Many senior officials and policymakers trained as engineers. At one point, all nine members of the Politburo Standing Committee, the Communist Party's highest ruling body, held engineering degrees. In 2002, Hu Jintao, then general secretary, had trained as a hydraulic engineer and worked on a dam. His deputy, the premier, was a geologist. More recently, an official who helped lead China's crewed space mission has moved on to run a major province. By contrast, the United States is described as a lawyerly society, where presidents tend to come from law schools. Among the first 13 US presidents, 10 were lawyers. The discussion also recalls a Soviet proposal to reverse rivers by detonating thermonuclear weapons, which was not carried out but illustrates the extreme engineering ambition it describes.

The discussion argues that decarbonisation will require huge amounts of construction, including solar farms, wind farms and transmission lines. China is well placed to deliver that, the programme says. Last year, China installed about 300 gigawatts of solar power, compared with about 30 gigawatts in the United States. China has around 45 nuclear power plants under construction and is building almost all of the world's ultra-high voltage transmission lines. It is also a leader in wind power. The country uses long-distance transmission to move solar and wind power from sparsely populated western regions, such as Ningxia, to large cities on the coast.

China is also pushing to electrify transport. One in two cars sold in China is now electric, compared with about one in 10 in the United States, according to the discussion. The programme cites the high-speed rail network as an example of how mega projects can change lives. A journey from Beijing to Yinchuan in Ningxia once took about 19 hours over a series of slow trains. After the final high-speed line opened at the end of last year, it takes six and a half hours. Another example given is the Hong Kong-Macau-Zhuhai bridge, which includes four artificial islands and stretches 55 kilometres.

The discussion also notes that China has faced climate impacts for decades, including droughts, floods and other extreme weather. It says Chinese leaders have used an engineering mindset to tackle these problems for centuries, and points to flood control in the mythos of the Chinese state. The debate remains unresolved: whether an engineering-first model can cut emissions fast enough, or whether the same construction culture will keep driving them up.
