GHG emissions in the transport sector must be reduced to meet global emissions reduction goals. Lightweighting of passenger vehicles can be an important part of the emissions reduction solution in the transport sector, but only if lightweighting scenarios are viewed in the context of the overall emissions of the vehicle. Many companies inside and outside of the transport sector use Life Cycle Assessment, which considers environmental impacts from the whole of a vehicle’s life cycle, as their primary method to develop this overall view. The University of California at Santa Barbara Automotive Energy and Green House Gas Model, developed on behalf of WorldAutoSteel, is a publicly available, peer-reviewed tool for the assessment of automotive emissions on a life cycle basis. Version 5 of the UCSB Model can be downloaded for free at worldautosteel.org/life-cycle-thinking/ucsb-energy-ghg-model/
Here in this video, Russ Balzer explains the contents and functionality of the model. A user guide is also available for download.
