Abstract : This study updates and supplements a previous (2001) North American study, conducted by GM and others (General Motors [GM] et al. 2001), of energy consumption and greenhouse gas (GHG) emissions associated with advanced vehicle/fuel systems (GM Phase 1 North American study). The primary purpose of this Phase 2 study is to address criteria pollutant emissions, including volatile organic compounds (VOCs), carbon monoxide (CO), nitrogen oxides (NOx), particulate matter with a diameter smaller than
10 microns (PM10), and sulfur oxide emissions (SOx). We also updated the vehicle modeling for energy consumption with the latest powertrain maps and added some additional propulsion systems, such as hydrogen internal combustion engines (ICEs).

As in the previous study, the vehicle modeled was a 2010-model-year, full-sized GM pickup truck. The truck was selected because it is a high seller among light-duty vehicles (cars and trucks) in the U.S. market, and light-duty trucks account for a large proportion of the fuel used in the U.S. vehicle fleet. In our study, we attempted to estimate the energy use and emissions for the 2010-model-year truck fleet over its lifetime. To simplify this effort, we modeled the year 2016 - when the lifetime mileage midpoint for the truck will be reached.
