EPA to Introduce Strongest-Ever Auto Emissions Limits in Push for EV Adoption.

The Environmental Protection Agency is expected to propose new rules limiting auto tailpipe emissions this week as part of a plan to accelerate a transition to electric vehicles in the U.S. The regulations would effectively require electric vehicles to account for 54% to 60% of new car sales by 2030 and 64% to 67% in 2032. Transportation is the country's largest source of greenhouse gas emissions, and curbing pollution from vehicles is a crucial aspect of the U.S. pledge under the Paris Agreement to cut emissions by 50% below 2005 levels by 2030.
