The European Commission published draft legislation July 11 that would require European Union automakers to make their vehicles 30 percent more fuel efficient by 2020. The 30 percent saving would equate to a CO2 emissions from cars reduction of 135.7 g/km currently to 95 g/km in 2020. Under a separate July 11 proposal, reductions in light van emissions would also be required, from 180 g/km currently to 147 g/km in 2020, a 19 percent reduction. Heavier vehicles would be allowed higher emissions than lighter vehicles, but all vehicles would need to reduce their emissions by the same proportion to stay within the fleet average limits.
