Transit spares air, saves money
The Bay Area's top seven transit agencies help prevent more than 2 million metric tons of greenhouse gases and save 251 million gallons of oil each year, according to a new report by a consumer-rights group.
The California Public Interest Research Group, or CalPIRG, said its report - along with news Thursday that the cost of oil hit a record high of nearly $106 a barrel - should encourage more people to park their cars and hop on a bus or train.
