Opportunities for Reducing U.S. Transportation’s Petroleum Usage and GHG Emissions

People mobility, largely in private vehicles, is the major source of U.S. transportation’s greenhouse gas emissions, followed by emissions from freight and air travel. All transport modes are totally dependent on petroleum-based fuels. Thus, reducing petroleum use and greenhouse gas emissions significantly is a major challenge. The scale of our transportation’s system dictates that for the next couple of decades improvements in mainstream powertrain and vehicle technologies, along with modest amounts of alternative fuels, will have the greatest impact. Longer-term we will need to transform the way we “energize” our various transportation systems if we are to clean and green it to the extent our climate change scientists are calling for. This seminar will attempt to frame a discussion of these bigger issues as well as review the types of transportation energy analysis that Professor Heywood and his team of students are working on.
