The Honorable Peter Buttigieg 

Secretary, U.S. Department of Transportation 

1200 New Jersey Ave SE 

Washington, DC 20590 

Dear Secretary Buttigieg: 

Congratulations on your confirmation as the 19th Secretary of the Department of Transportation. We are grateful for your service and look forward to working with you. 

We are writing to urge the Biden administration to reinstate the greenhouse gas (GHG) performance measure. This can be done immediately through executive action initiating a notice of proposed rulemaking to reinstate the measure. 

Transportation accounts for the largest share of carbon emissions in the United States, and these emissions are rising. Yet in 2017, the Trump administration repealed the GHG performance measure that would have required states to measure and reduce GHG emissions from transportation. With the climate crisis worsening, we must take immediate action to reduce emissions from the transportation sector. 

In addition to those undersigned, reinstating the GHG performance measure is supported by 47 Senators and Members of Congress who, led by Senator Ben Cardin and Congressman Earl Blumenauer, recently wrote to ask that you “urgently” restore this critical policy. 

Thank you for considering this request. We look forward to working together on this important issue. 

Sincerely, 

Beth Osborne, Director 

Transportation for America
