TIAX has a long history of developing and implementing incentive programs to help deploy a broad range of low- and zero-emissions vehicle types, including light-duty cars and trucks up to Class 8 diesel trucks. In fact, it was our California staff that helped develop the concept of incentive programs as a viable tool to reduce motor vehicle emissions. We played a key role assisting the California Air Resources Board to develop and launch the pioneering Carl Moyer program. Over the last 12 years, this program has disbursed hundreds of million of dollars for deployment of low-emitting transportation projects. TIAX developed and implemented the Gateway Cities Council of Governments fleet modernization program, an incentive-based effort that resulted in the replacement or retrofit of nearly 700 heavy-duty trucks serving in goods movement vocations around greater Los Angeles. The Gateway Cities program was the harbinger of the world's largest drayage truck replacement program, the San Pedro Bay Ports Clean Trucks Program (Ports of Los Angeles and Long Beach), for which TIAX is the lead technical contractor and grants program manager. TIAX is also helping to develop and implement various similar incentive programs across the country, such as the Clean Trucks Program for the Port Authority of New York - New Jersey.
