RMI analyzed one year of trucking telematics data in 15 states that have adopted or are working to adopt the Advanced Clean Trucks (ACT) regulation to understand how trucks currently operate and to quantify electrification potential. The profiled states have all signed the Advanced Clean Trucks Memorandum of Understanding (MOU) that requires 30 percent of MHD vehicle sales be zero-emissions vehicles (ZEVs) by 2030, with a goal of 100 percent ZEV adoption by 2050. Some states have enacted the MOU, while others are still working on adoption.
