In 2007, CNW published a study called Dust to Dust which reports the results of a life cycle analysis that compared the environmental impact of a Toyota Prius and a Hummer H3. The report claims that the Prius has a greater environmental impact than the H3. In response to this report, RMI authors performed a life-cycle analysis using the widely-accepted GREET model established by Argonne National Laboratory. The results of the RMI analysis show that even in conditions favorable to the H3, the environmental impact of the Prius is still lower than that of the H3. This report describes the findings in detail.”
