Checking Dust to Dust’s Assumptions about the Prius and the Hummer: Fact-checking using the GREET life cycle model underlines the deep divide between the Dust to Dust study and all previous scientific work
The Rocky Mountain Institute (RMI) conducted a fact-check of a report by CNW Research/Marketing titled 'Dust to Dust,' which claimed the Toyota Prius has a greater environmental impact than the Hummer H3 SUV. Using the GREET life cycle model developed by Argonne National Laboratories, RMI found that the Prius consistently has a lower environmental impact in terms of greenhouse gas emissions and energy consumption, even when manipulating variables to favor the Hummer.
