Why Doesn't my Output Vehicle Miles Traveled (VMT) Match my Input VMT?
See More Frequent Questions about MOVES and Related Models . This problem usually occurs when the run specification does not include all possible vehicle and fuel types. MOVES internally allocates the input VMT to each of the source types and fuel types and only reports the VMT for the fuel…

Is there any volume cap when using previously-retired 2008 or 2009 biodiesel RINs to satisfy an obligated party?s 2010 Biomass Based Diesel RVO? Can 2008 or 2009 biodiesel RINs that were previously-retired in 2009 also be used to satisfy Advanced Biofuel
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . 2008 and 2009 biodiesel and renewable diesel RINs (that is, RFS1 RINs with a D code of 2 and RR code of 15 or 17) used for compliance purposes in 2009 can also be used to reduce the…

How does MOVES Calculate CO2 and CO2 Equivalent Emissions?
See More Frequent Questions about MOVES and Related Models . MOVES calculates the energy it takes to operate an onroad vehicle based on energy consumption rates as explained in the technical reports Greenhouse Gas and Energy Consumption Rates for Onroad Vehicles MOVES3 (pdf) (November 2020, EPA-420-R-20-015) and Exhaust Emission Rates…

The regulations at 80.1427(a)(7)(iii) say that 2008 biodiesel RINS + 2009 biodiesel RINs cannot exceed 20% of the 2010 RVO. Does this mean that 80% of the 2010 biomass-based diesel RVO has to come from 2010 RINs?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The 20% rollover cap under RFS2 is the same as the rollover cap under the RFS1 program. However, the rollover cap only places a limit on previous year RINs that were NOT used for compliance in 2008 or…

Under section 80.1405, the standard for biomass based diesel (BBD) is calculated via a fraction, the numerator of which is equal to the RFV for BBD in compliance year i times 1.5. For 2010 only, would you agree that, using the example of the calculation f
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The percentage standard for biomass-based diesel in years 2011 and beyond will be based upon the volumes specified in CAA 211(o)(2)(B)(i)(IV), unless some portion of that volume is waived per CAA 211(o)(7)(E). For 2010, the numerator of the…

What Drives Seasonal CO Emission Trends?
See More Frequent Questions about MOVES and Related Models . Once a vehicle’s engine/catalyst reaches operating temperature, the ambient temperature has little effect on the emissions performance of the vehicle. These “running” emission rates in MOVES have no temperature adjustment. However, during summer months at warm temperatures, MOVES assumes extensive…
