EPA released proposed rules ramping up emissions requirements for cars and trucks, which are expected to drive electrification of the transportation sector.

The revised Effluent Limitations Guidelines and Standards would build on standards set under President Obama but weakened under President Trump.

The Biden administration could be close to restoring California’s authority to adopt tailpipe emission standards that are more stringent than federal standards.
