Administration again delays Keystone pipeline decision
This pipeline should have been approves years ago. Instead, Obama administration is delaying a decision again, probably to after the midterm elections. Given how critical the Senate is and that the endangered Democrats support the pipeline I fear that he already decided to reject the pipeline but doesn't want to announce it before the elections.
That would be a big mistake. Pipeline transport is safer, cheaper and more energy efficient than rail. So rejecting the pipeline and having to haul the oil sands by rail will actually increase carbon emissions.
And even if ecomenatlists managed to shut down Canadian oil sands completely not even that will decrease emissions because there are other sources of oil sands like Orinoco Belt in Venezuela. Of course compared to Canada Venezuela is further away, has less strict environmental regulations and is rather unstable politically.
