Rio Tinto and Alcoa Corporation announced a revolutionary process to make aluminum that produces only oxygen as a by-product, eliminating all direct greenhouse gas emissions from the traditional smelting process. In Canada alone, use of the technology could eliminate the equivalent of 6.5 million metric tonnes of greenhouse gas emissions, if fully implemented at existing aluminum smelters in the country. That represents an amount roughly equal to taking nearly 1.8 million light-duty vehicles off the road. . . .
