Maine residents who buy low-polluting, high-mileage cars would be eligible for rebates of up to $3,000 under a bill that will go before the state legislature in January.

In other clean car news, Vietnam announced this week that it plans to phase out the use of leaded gasoline, the only type of fuel now in use in vehicles in the nation.
