Historical emissions from the transportation sector are listed in Table 4-1. The table shows total sector
emissions and total CH4 and N2O emissions for select years and it also highlights the emissions from fuels
that either make up a very large portion of sector emissions or are used to power AFVs in the state.
Diesel powered vehicle fuel emissions come from jet fuel/kerosene (to a much lesser extent) and
distillate fuel (which is the majority of diesel vehicle fuel emissions); when used in diesel-powered
vehicles these fuels are otherwise referred to as #1 and #2 diesel, respectively. The SIT does not provide
for the separation of fuel types in a way to highlight diesel fuel emissions specifically.

Despite the increase in VMT since 2009, transportation emissions have been somewhat stable due to a
cleaner fleet of motor vehicles statewide. This is the result of the EPA's strengthening of vehicle
emissions standards. Beginning in 1996, vehicles not only came equipped with an onboard diagnostics
system to self-test for emissions systems failures, but they also faced much more rigorous federal
emissions standards. The EPA has continued to strengthen new vehicle emissions standards as well as
vehicle fuel standards. As older vehicles "age-out" of the fleet consisting of all on-road vehicles and are
