California Phase 2 Trailer Certification Requirements
Print this Article | Send to Colleague
The California Air Resources Board (CARB) staff has posted the following certification application forms to the Phase 2 greenhouse gas (GHG) trailer certification webpage:
Trailer certification web form;
Trailer certification application guidance document (step by step walk through of how to fill out the certification application);
Statement of Compliance;
Tire report and tire data CSV submission instructions;
Labeling, warranty, and maintenance statement instructions; and
Compliance verification calculator.
To receive an executive order to be allowed to sell trailers in California, manufacturers must submit a trailer certification application web form along with the necessary supporting documentation for CARB approval. The above documents now posted on the trailer certification webpage provide guidance to manufacturers on how to fill out the certification application web form and instructions on how to develop supporting documentation necessary to be included in your trailer certification package. Moving forward, CARB will continue to post additional resources to further assist manufacturers through this certification process.

Background
In 2018, California adopted GHG standards that largely align with the U.S. EPA and the National Highway Traffic Safety Administration (NHTSA) GHG standards for new medium- and heavy-duty engines, vehicles, and trailers sold in California. The regulations will reduce GHG emissions from on-road medium- and heavy-duty vehicles.
The California Phase 2 regulation establishes CO2 emission standards for certain trailers used in combination with tractors. California Phase 2 trailer standards take effect for all trailer manufacturers in 2020. The standards are intended to make trailers more efficient and lower the greenhouse gas emissions associated with their use. Affected trailer types include box-type trailers (dry van and refrigerated van trailers of all lengths), flat bed trailers, tank trailers, and container chassis. The trailer standards can be met through aerodynamic improvements, low rolling resistance tires, tire pressure systems (Tire Pressure Monitoring System and/or Automatic Tire Inflation System), and/or weight reduction. Beginning January 1, 2020, trailer manufacturers must certify to California standards and receive an Executive Order from CARB to legally sell trailers in California. At the workshop, staff will discuss the trailer certification process and provide details on the required test data and documentation manufacturers must submit to CARB in order to receive an Executive Order to sell in California.
