China’s aluminum manufacturing CO2 emissions doubtless peaked in 2024, not as a result of manufacturing collapsed or as a result of a single coverage out of the blue bit, however as a result of the construction of the place aluminum is made and the way it’s made modified in ways in which compound over time. Aluminum is a helpful materials to look at as a result of it’s dominated by electrical energy demand, geographically delicate, and produced at a scale the place comparatively small structural shifts present up clearly in nationwide emissions information.
Aluminum output in China 2010 to 2040 by creator
China now produces about 44 million tons of major aluminum per 12 months, near 60% of world output. Producing one ton of major aluminum requires roughly 13 to fifteen MWh of electrical energy, relying on potline design and working circumstances. In coal dominated grids widespread in northern China a decade in the past, electrical energy alone added round 9 to 14 tons of CO2 per ton of aluminum, earlier than accounting for an additional 1.5 to 2 tons from carbon anodes. At scale, this made aluminum certainly one of China’s most emissions intensive industrial actions, with complete sector emissions simply exceeding 400 million tons of CO2 per 12 months.
From the early 2000s by way of about 2014, aluminum manufacturing expanded quickly in…
