Strategies for Transitioning to Low-Carbon Emission Trucks in the United States


This white paper reviews previous studies on prospects for reducing CO2 emissions from trucks. It provides a new investigation into the feasibility of achieving an 80% reduction in CO2-equivalent (CO2e) greenhouse gas (GHG) emissions in the United States and California from trucks by 2050. The authors assess the technological and economic potential of achieving deep market penetrations of low-carbon vehicles and fuels, including vehicles operating on electricity, hydrogen, and biofuels. Achieving such a target for trucks will be very challenging and, if focused on hydrogen and electric zero emission vehicle (ZEV) technologies, will require strong sales growth beginning no later than 2025.
