Scientists Analyze Hybrid Construction Vehicle Emissions

Scientists at the University of California, Riverside’s Center for Environmental Research and Technology have received $2 million to study hybrid construction vehicles.

The project, funded by the California Air Resources Board, will evaluate the emission reduction benefits of two commercially-available hybrid construction vehicles: a Caterpillar bulldozer and a Komatsu hydraulic excavator. 

The research is part of a larger effort by the California Air Resources Board to expand the use of hybrid technology to help meet the goals of a 2006 state law aiming to reduce greenhouse gas emissions to 1990 levels by 2020—a 30 percent reduction.
