Executive Order 13432: Cooperation Among Agencies in Protecting the Environment With Respect to Greenhouse Gas Emissions From Motor Vehicles, Nonroad Vehicles, and Nonroad Engines
President: George W. Bush
Directed coordinated federal work on motor-vehicle greenhouse gases and alternative fuels after Massachusetts v. EPA.
Status: In effect. Is Executive Order 13432 still in effect? Yes. Executive Order 13432 remains in effect. See Federal Register record.
What does Executive Order 13432 do?
EPA later explained that work began in response to EO 13432, then changed course after the 2007 energy law; it issued a greenhouse-gas advance notice in July 2008.
Before and after
Before the order
EPA and transportation agencies had distinct statutory roles concerning vehicle emissions and fuel economy.
After the order
EPA later explained that work began in response to EO 13432, then changed course after the 2007 energy law; it issued a greenhouse-gas advance notice in July 2008.
EPA's later actions rested on the Clean Air Act and other statutes; this coordination order did not itself set emissions standards.
