European Committee for Standardization report says E20 reduces carbon emissions by 10% vs E10

In Belgium, Horizon Magazine reports that the European Committee for Standardization commissioned a report from its Dutch counterpart NEN to look at the impacts of raising ethanol blending to 20% in Europe as a baseline to help develop future standards for the higher blend by 2030. The study showed that vehicles manufactured after 2011 should all be able to operate without challenges on E20. The study also says that although overall fuel consumption will rise because of ethanol’s lower energy density than gasoline, carbon emissions will fall by 10% compared to E10.
