Saving Energy Through Public Transportation Act of 2008 - Authorizes appropriations for FY2008-FY2009 for public transportation formula grants. Authorizes the Secretary of Transportation to make such grants for: (1) operating costs of equipment and facilities being used to provide the public transportation the grant recipient is no longer able to pay as a result of reducing fares; (2) operating and capital costs of equipment and facilities being used to provide transportation services that the recipient incurs as a result of expanding such services; (3) the avoidance of increased fares or decreased services; (4) the costs of acquiring clean or alternative fuel vehicle-related equipment or facilities; and (5) administrative costs in establishing or expanding services to provide commuters with information about alternatives to single occupancy vehicle use.
Requires a grant that involves acquiring clean or alternative fuel vehicle-related equipment or facilities for complying with the Clean Air Act to be for 100% of the net project cost unless the grant recipient requests a lower percentage.
Amends the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users to require federal employees in urbanized areas served by fixed route public transportation to be offered transit pass transportation fringe benefits. Requires: (1) the Secretary to issue guidance on nationwide implementation of a transportation fringe benefit program; and (2) agencies to report on program implementation.
Requires the Secretary to establish a pilot program to carry out vanpool demonstration projects in not more than three urbanized areas and two other areas.
Requires a grant for a capital project during FY2008-FY2009 that involves additional parking facilities at an end-of-line fixed guideway station or at a park-and-ride lot that serves a fixed route commuter bus route that is more than 20 miles in length to be for 100% of the net capital cost of the project unless the grant recipient requests a lower percentage.
Requires the Secretary of Transportation to carry out a national consumer awareness program on the environmental, energy, and economic benefits of public transportation alternatives to the use of single occupancy vehicles.
