For the past 30 years Stefan has supported state, Federal, and international efforts to examine the greenhouse gas impacts of conventional and alternative fuels including California's Zero Emission vehicle program and Low Carbon Fuel Standard. His current work includes assessments of the process integration, cost, and market potential of low carbon fuel production technologies. Stefan has published more than 90 studies for government agencies as well as peer reviewed papers on alternative fuels and life cycle analysis.

Stefan has directed the modifications to the California GREET model, which was used to evaluate greenhouse gas emissions under the California Fuel Standard, while also working with hundreds of clients to examine greenhouse gas emissions from fuel production technologies. Stefan received a bachelor’s degree in Mechanical Engineering from the University of California, Berkeley, and also serves as the Managing Director of Life Cycle Associates.
