Hillary Clinton opposes Keystone, but other pipelines have forged ahead

Clinton has taken a stance on Keystone XL, but in the meantime, TransCanada has moved on and new tar sands projects are being prepped at the border

At a campaign stop in Iowa on Tuesday, presidential candidate Hillary Clinton broke her silence on where she stands on TransCanada's Keystone XL pipeline: "I oppose it because I don't think it's in the best interest of what we need to do to combat climate change."

But while politicians have been dithering over the increasingly unpopular Keystone XL, international tar sands development and other carbon-intensive pipeline projects have been charging ahead.
