Biden Finalizes New Rules to Cut Auto Emissions Nearly in Half by 2032, Accelerating Transition Toward Electric Vehicles

The Biden administration finalized new tailpipe emission rules to push the auto industry toward electric vehicles and hybrids, though the phase-in is slower than originally proposed.

The new standards allow automakers more flexibility to meet targets through a mix of efficient gas engines, hybrids, plug-in hybrids and battery electric vehicles.

The rules are expected to slash passenger vehicle emissions nearly in half by 2032 compared to 2026 levels, reducing over 7 billion metric tons of climate pollution.

The transition has sparked political debate, with President Biden touting economic benefits but facing concerns from unions and Republicans about impacts.

Reducing vehicle emissions provides public health benefits by cutting smog, particle pollution and other hazards linked to cancer, stroke, heart disease and more.
