 Here, due to the tier1 emission factors applied, annual emissions strongly correspond with activity data, therefore showing strong decline after 1990 and an ongoing downward trend.
-As to the peak in NO<sub>x</sub> emissions 2005: Here, diesel oil deliveries data show a peak in 2005 resulting in emission estimates well above the values of previous and following years. Due to the applied approach, the resulting outliers have already been looked into in several NEC and CLRTAP Reviews. However, given the underlying activity data, the noticeable emission estimates cannot be revised in a sensible way.
+Regarding the peak in NO<sub>x</sub> emissions 2005: The dominating source of NO<sub>x</sub> (and PM) emissions is the use of diesel oil in militar ground vehicles and machinery as well as military vessels. Here, the underlying activity data (annual diesel oil inland deliveries) for 2005 are well above the values of previous and following years but cannot be revised in a sensible way.
