EPA's final rule on light-duty vehicle emissions aims to give the industry more time and flexibility on how to reach its ambitious targets.

The California Air Resources Board approved its largest budget yet for incentive programs for clean cars, trucks and buses.

With a provision for PHEVs, California’s Advanced Clean Cars II regulations won’t completely eliminate internal combustion engines in new vehicles.

CARB adopted regulations that will require all new cars sold in the state to be zero-emission or plug-in hybrid by 2035, a trailblazing move, the agency says.

California regulators are fine-tuning a set of draft rules that would transition the state to 100% light-duty ZEV sales by 2035.

Low-income residents in certain parts of California are finding their EV incentives are accompanied by a tax liability.

Under Vermont's plans to ramp up EV adoption, gas tax revenue losses from light-duty cars could total $80 million in 2050, according to a new study.

Top incentive would drop from $5,000 to $2,500 for EVs priced up to $45,000 as state aims to target consumers who might not buy an EV without the rebate. 

New Jersey outlined new rules to encourage drivers to buy lower-priced EVs, with a maximum incentive available only for vehicles priced $45,000 and below.
