On January 26, 2016, Global Automakers and the Auto Alliance submitted a letter to California Air Resources Board (ARB) stating concerns with the 1 mg/mile measurement standard for 2025 based on ARB staff's presentation at the October 22, 2015 board hearing. The letter addresses the following:
- Feasibility and readiness to measure PM at 1 mg/mi
- Current data not being representative of the future fleet
- The need to consider and incorporate PM index of fuel
Global Automakers and the Auto Alliance have held meetings with ARB staff on this issue and look forward to continued collaboration.
Details can be found in the attached letter.
