According to a recently released report by the United Kingdom’s Society of Motor Manufacturers and Traders, the average CO2 emissions from new UK cars has fallen 13.1% at the same time that diesel penetration has risen roughly the same percent, from 26.5% to 40.2%.

With President Obama’s newly announced fuel economy standards, autmobile manufacturers could be looking to speed their introduction of diesel vehicles in the U.S., as has been recently reported about Subaru’s Outback. In this way, transportation CO2 reductions could be fast-tracked until other electric and other alternatively powered vehicles become commercially available.
