and the paragraph of interest:
One part of the nearly two-hour hearing that jumped out at us was from Frederick Smith, the chairman, president and CEO of FedEx and also a member of the Electrification Coalition. Smith said:
In 2007, the Natural Resources Defense Council and the Electric Power Research Institute published a well-to-wheels analysis of several different automotive technologies fueled by a range of sources commonly used to generate power. Their analysis concluded that using a PHEV would reduce carbon emissions as compared to a petroleum-fueled vehicle even if all of the exogenous electricity used to charge the PHEV was generated at an old coal power plant. Whereas a conventional gasoline vehicle would be responsible for emissions, on average, of 450 grams of CO2 per mile, a PHEV that was charged with power generated at an old coal plant would be responsible for emissions of about 325 grams of CO2 per mile, a reduction of about 25 percent. Emissions attributable to the vehicle could be reduced to as low as 150 grams of CO2 per mile if the exogenous power was generated at a plant without carbon emissions and ranged between 200 and 300 grams of CO2 per mile if the power used was generated using other fossil fuel generation technologies. In other words, no matter where the power consumed by a PHEV is generated, the overall level of emissions attributable to its operation is lower than that of a conventional gasoline vehicle. The EPRI/NRDC study findings were consistent with a 2007 MIT study that examined the same issue.
