OTTAWA — New fees for gas-guzzling vehicles, rebates for their fuel-efficient counterparts, and a tightening of tax regulations for petroleum producers are among some of the key environmental measures introduced Monday in Finance Minister Jim Flaherty's federal budget.

While consumers who buy or lease fuel-efficient vehicles could benefit from rebates of up to $2,000, motorists who buy gas guzzlers could see the price tag increase by $1,000 to $4,000 because of a new "green levy on fuel-inefficient vehicles.
