What the bill will do
Reduce global warming emissions from new cars sold in Maryland by, on average, 30 percent by 2016.
Penalize automakers that don't meet the standard. They must offer customers incentives to buy hybrids and other efficient vehicles.
Cost buyers about $1,000 more per vehicle, on average. Most of the cost will be for big vehicles that need engine upgrades to pollute less.
Require all cars sold in Maryland to have about $150 in smog-control equipment not standard in most states.
