On your chart, there is a section entitled: “Reducing GHG” and a whole series of figures. The total adds up to 48 tons. With respect to the 2007 engine, you say that it is basically smog-free. At the same time, you're saying that it uses a bit more energy and is a little less energy-efficient.
What does that correspond to in terms of tons per year? If we consider the “pluses” and the “minuses”, to what extent does the vehicle reduce overall greenhouse gas emissions?
