- University of Michigan Eco-Driving Index (EDI) and the two sub-indexes (EDId and EDIf) for October 2007 through November 2012
The values of the index (EDI) and of its two sub-indexes (EDIf and EDId) from October 2007 through November 2012 are shown in the figure and table below.
The EDI for November 2012 stands at 0.82, indicating that in November 2012 there was an 18% reduction of emissions per driver of newly purchased vehicles compared to the situation in October 2007. (EDIf and EDId for November 2012 are 0.85 and 0.96, respectively.)
Future monthly values of the EDI will be issued with a lag of about two months (due to lags in the availability of the underlying data). (Data for recent months are occasionally updated in the underlying FHWA and EPA data sources, possibly resulting in small changes to recent sub-index and EDI values.)
