Sometimes, candidates get a little unrealistic with their promises.
As a candidate, Barack Obama said he would require governors and local leaders in metropolitan areas to include energy conservation in their planning for projects that rely on federal transportation money.
Broadly speaking, energy conservation has been part of President Obama's agenda.
Under Obama, the Transportation Investment Generating Economic Recovery, or TIGER, program has provided $3.1 billion in grants to state and local governments for 218 transportation projects that promote environmental sustainability.
His administration has sought more stringent fuel economy standards for passenger cars.
We also found the Partnership for Sustainable Communities, an initiative launched in 2010, which aims to locate people near transit centers, reducing commute times and gas consumption while increasing affordable housing options.
"I think this administration has been more cognizant of this idea of improving the energy performance of our transportation systems than any president maybe since Jimmy Carter," said Kevin McCarty, assistant executive director of the U.S. Conference of Mayors.
Jesse Prentice-Dunn, transportation policy analyst for the Sierra Club, called the Transportation Department's energy-conservation efforts "phenomenal," especially with the TIGER grants.
Prentice-Dunn also referred us to the administration's support of a Senate transportation bill awaiting a vote in the House. The bill uses energy conservation as a state and metropolitan transportation planning objective and calls for research and development that would promote sustainability and environmental protection.
Deron Lovaas, director of the Federal Transportation Policy, Energy and Transportation Program at the National Defense Resource Council, said the Senate bill could have a positive effect on energy conservation in terms of freight policy objectives and shifting funding away from federal highways.
"But overall, it sadly falls far short of the campaign promise," Lovaas said.
No one we interviewed could point to an existing or recently proposed requirement that energy conservation be a condition of receiving federal transportation dollars at the state or local level.
Tanya Snyder, editor of Streetsblog Capitol Hill, said Obama's energy-conservation promise is difficult to deliver when there is such strong political resistance to imposing federal requirements on states.
"There's so much passion among the Republicans and conservatives in the freshman class in preserving states rights," Synder said.
McCarty, of the U.S. Conference of Mayors, said Obama's energy-conservation requirement would have been unprecedented in federal funding of state and local transportation.
"There's nothing else like that in the system," he said.
This is a clear case that Obama promised more than was realistic.
The promise was specific in calling for federal transportation funding to be granted on the condition of energy conservation in state and local transportation planning. Nothing like that exists. We rate this a Promise Broken.
