“dirty” as it produces more greenhouse gases in obtaining it compared to other methods
of obtaining oil. This would make Alberta oil less welcome in European refineries. It
would be a blow to the industry if European countries reduced the amount of oil they
purchased from the oil sands. Use print and electronic sources to research this issue.
Do you agree or disagree that the oil should be labelled as “dirty”? Explain your position.
