California Air Resources Board (CARB) staff invites you to participate in a public workshop to discuss potential regulation concepts to transition non-truck transport refrigeration units (TRU), which include trailer TRUs, domestic shipping container TRUs, railcar TRUs, and TRU generator sets, to zero-emission technology.  

At the workshop, staff will present updates to the potential regulatory concepts made since the last workshop held in November 2023, as well as discuss estimates on cost inputs, zero-emission technology, and non-truck TRU operations route characteristics. Staff plans to solicit input from TRU owners, operators, and original equipment manufacturers on all the mentioned topics.
