The city's taxi fleet as of this morning is comprised of 55 percent alternative fuel vehicles, including hybrids and compressed natural gas vehicles. These fuel-efficient vehicles have reduced gas consumption by 2.9 million gallons per year and lowered greenhouse gas emissions by 35,000 tons annually.

AT&T today announced the deployment of the 2,000th alternative fuel vehicle and 1,500th compressed natural gas (CNG) vehicle in its corporate vehicle fleet, giving it one of the largest CNG vehicle fleets in the U.S.  These milestones are part of a $565 million planned investment announced in March 2009 to replace more than 15,000 fleet vehicles with alternative fuel models through 2018.  Currently, the AT&T corporate fleet includes more than 75,900 vehicles.

AT&T anticipates purchasing approximately 8,000 CNG vehicles over a five-year span, at an anticipated cost of $350 million.  AT&T expects to spend an additional $215 million through 2018 to replace 7,100 fleet passenger cars with alternative fuel models.  According to the Center for Automotive Research (CAR), AT&T's alternative fuel vehicle initiative will:

 - Save 49 million gallons of gasoline over the 10-year deployment period.
 - Reduce carbon emissions by 211,000 metric tons – the greenhouse gas equivalent of removing 147,929 passenger vehicles from the road for one year.
