To Clean Up Oil Sands’ Dirty Image, Alberta May Try Emission Tax

Alberta’s new government is engaged in a balancing act. It’s trying to cut carbon emissions while protecting an oil-sands industry that supports hundreds of thousands of jobs.

Tar sands are found almost exclusively in the western Canadian province. They produce a product that generates about 17 percent more carbon dioxide on average than conventional oil, and emissions in Alberta have risen by more than 53 percent since 1990. At the same time, they’re the nation’s single most valuable export, making up nearly a fifth of total foreign sales.
