Ford researchers: global light-duty CO2 regulatory targets broadly consistent with 450 ppm stabilization

Green Car Congress

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. The biodiesel blend share is restricted to 7% by energy through 2020, consistent with regulations.
