On Tuesday, the Biden administration released a plan to guide the U.S. to eliminate carbon emissions from the transportation sector, the leading emitter of U.S. greenhouse gasses warming the planet, by 2050. That blueprint includes spending billions of public dollars to expand the use of electric vehicles and low-carbon fuels. POLITICO’s Catherine Morehouse breaks down the details of the administration’s plan and its challenges. Plus, President Joe Biden appointed Elizabeth Klein to lead the Bureau of Ocean Energy Management, which has drawn criticism from Republicans and some Democrats for its lack of oil lease sales.   Josh Siegel is an energy reporter for POLITICO.  Catherine Morehouse is an energy reporter for POLITICO.  Nirmal Mulaikal is a POLITICO audio host-producer.
