Buyers who are considering hybrids as they look at used cars in New Jersey won’t have to worry about new emissions rules in the region.

New Jersey, Pennsylvania and several other states in the region recently applied for cleaner car standards from the EPA based on regulations used by California which are stricter, according to the Environmental Defense Fund.

A report from the fund shows the effects of driving cleaner cars, such as hybrids, on less affluent families who represent a quarter of the populations who drive used cars in New Jersey. The data shows that they could save up to $4.1 billion in costs because of the more fuel efficient vehicles.

“Cleaner cars are a trifecta that will save families money at the gas pump, reduce our dependence on foreign oil, and cut global warming pollution from tailpipes,” said James Fine, economist and policy scientist at the fund.

Less affluent drivers of used cars in New Jersey could benefit the most from the new regulations since their transportation costs are double that of wealthier motorists as a percentage of one’s monthly budget.
