The Energy Department (DOE) failed to comply with a White House directive to reduce the travel costs incurred by its contractors, which reached $300 million over a six-year period, according to a recent report by the department’s inspector general.

While DOE has cut spending for its federal employees, the report said the department has largely ignored the contractors who account for 85 percent of DOE’s travel spending. The department spent $360 million total on foreign spending in the six-year period from fiscal 2007 to 2012.

“Despite the sizable expenditure of Federal funds, the Department had not made a concerted effort to reduce contractor international travel costs,” DOE Inspector General Gregory Friedman wrote in the report issued last week.

President Obama told federal agencies to shed travel expenses in a November 2011 executive order.
