The SMP model calculates 2000?2050 The Ford team updated the SMP model with historical data for 2000, 2005, and 2010, and extended the model to calculate the total CO 2 emissions (tonnes) and the TTW (tank-to-wheel) emission rate (g CO 2 /km) for the new vehicle fleet. They converted from an absolute amount to scale relative to 2000.
