Since Rio Tinto bought Canada’s Alcan in 2007, the Anglo-Australian mining giant has been good at making big promises, but slow to fulfill them. This is especially proving to be the case with its plan to produce zero-carbon aluminum.
The Quebec aluminum operations that Alcan built up over more than 80 years until its US$40-billion takeover by Rio Tinto remain among the world’s most profitable. Rio’s eight wholly and jointly owned smelters in the province mostly rely on cheap and emissions-free hydroelectric power from dams that Alcan itself built, providing a competitive and environmental advantage over U.S., Chinese and Russian rivals that use coal-based electricity.
