EPA Unveils Ambitious New Vehicle Emissions Rules to Cut Pollution, Boost Electric Car Sales

New EPA auto emissions rules aim to cut carbon pollution, boost electric vehicles and hybrids through 2032. Rules ramp up over time, getting close to initial ambitious proposals.

Rules projected to avoid over 7 billion tons of emissions and provide nearly $100 billion in net benefits over next three decades.

Aims for 56% of new vehicle sales to be electric by 2032, along with 13% plug-in hybrids. Huge increase over current 7.6% EV sales.

Slower phase-in of stricter standards from 2027-2029 after industry said initial proposals were unworkable. Ramps up by 2032 to near original proposal.

Environmental groups optimistic rules will significantly cut vehicle emissions, but may not meet Paris Climate Accord commitments. Industry says pace still challenging but more reasonable.
