In a guest column published in the newspaper, Redford touts the benefits of the pipeline, which — if approved — would take heavy oil from Alberta to refineries on the U.S. Gulf Coast.
But Redford also emphasizes Alberta's record on the environment and its commitment to reducing climate change.
The premier notes that Alberta has a levy on heavy carbon emitters and is redirecting that money into clean energy projects.
The column is the latest attempt by Redford's government to refute protesters, who have gathered by the thousands in Washington to demand the Keystone line not be approved.
They have labelled the carbon-intensive oilsands "dirty oil" and U.S. President Barack Obama has made clear he wants all nations to take a more active approach on climate change.
