A new report by the American Action Forum, a center-right policy institute, details adverse economic consequences of the Keystone XL pipeline’s delay. The report highlights billions of dollars in untapped economic activity, and the over $1 trillion the U.S. has paid other countries for oil. It also details additional environmental benefits that could be provided by passing Keystone.

TransCanada, the company that would operate the pipeline, has been waiting for authorization on the project since September 2008. By breaking down crude oil prices over the past years, AAF estimates “$175 billion in economic activity has been unrealized due to the delay.” Furthermore, “at today’s price of crude at $51.76, this would gross over $42 million dollars a day or roughly $15 billion per year.”
