Argonne National Laboratory’s Systems Assessment Center has released their 2019 suite of GREET Models. The GREET model is a unique analytical tool that simulates the energy use and emissions output of carious vehicle and fuel combinations. It uses full life cycle–from well to wheels–assessments for fuels and raw materials to vehicle disposal. The 2019 updates are extensive, especially for direct nitrous oxide emissions (relevant to natural gas vehicles) and hydrogen/fuel cell electric vehicles. More >>
