Urging EMA to affirm its commitment to the endangerment finding and to withdraw support for repealing the vehicle GHG emissions standards

Nineteen clean freight advocates are calling on members of the Truck & Engine Manufacturers Association (EMA) to withdraw support for the repeal of the U.S. EPA's Phase 3 greenhouse gas (GHG) emissions standards for medium- and heavy-duty vehicles. The authors argue that the EMA's decision to intervene in litigation to repeal these standards and the Endangerment Finding undermines public health, climate protections, and the U.S.'s ability to comply with the Paris Agreement. They claim that this regulatory instability hinders manufacturer investment and risks U.S. competitiveness against domestic competitors like Tesla and global competitors such as BYD. The letter suggests that companies should distance themselves from the EMA or withdraw membership to signal support for durable clean transportation policy.

• The authors argue that the Trump Administration's repeal of the Endangerment Finding and vehicle GHG emissions standards removes the foundation of U.S. climate policy and impairs the country's capacity to meet its obligations under the Paris Agreement.
• The repeal of these standards is described as a poor business decision that creates regulatory instability, making it difficult for manufacturers to manage capital allocation, supply chains, and investments.
• According to an analysis by the EPA, the repeal of these standards could result in costs to Americans totaling $180 billion over the next ten years.
• The letter warns that dismantling the policy framework supporting innovation risks losing market share to domestic competitors like Tesla (with the Tesla Semi) and global competitors such as BYD from China.
