Hao Cai is an environmental and energy systems analyst examining life-cycle energy and environmental impacts of the production and use of transportation fuels and vehicle technologies. Dr. Cai specializes in characterizing air pollutant emissions of stationary sources and light-duty and heavy-duty vehicles, in analyzing energy efficiency and greenhouse gas emissions of the power sector and petroleum and natural gas systems, and in assessing the energy use, greenhousegas emissions, and air pollutant emissions of biofuel production systems. Much of Cai’s work is incorporated into Argonne’s Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREETTM) model, which has more than 23,000 users worldwide.
