Michael Wang has led the development and applications of Argonne’s GREET (Greenhouse gases, Regulated Emissions, and Energy use in Technologies) model for life-cycle analysis of vehicle technologies, transportation fuels, and other energy systems. His work in the life-cycle analysis area has been used by government agencies and industries, and cited extensively in research and academic fields. As of 2023, there are more than 55,000 registered GREET users worldwide. Dr. Wang has worked closely with governmental agencies, automotive companies, energy companies, universities, research institutions, and nongovernmental organizations (NGOs) in the United States, China, Brazil, Canada, Japan, and Europe to address energy and environmental issues related to the transportation sector and energy systems.
