Transportation accounts for 25% of US annual carbon dioxide (CO2) emissions, and is estimated to grow. According to a comprehensive joint environmental study by EPRI and NRDC in July 2007, widespread adoption of PHEVs can reduce GHG emissions from vehicles by more than 450 million metric tons annually in 2050 equivalent to removing 82.5 million passenger cars from the road!
