The differences in emissions between navigation and civil aviation are much
larger than the differences in fuel consumption and display a poor emission
performance for international sea transport. In broad terms, the emission
trends shown in Figure 3.82 are similar to the fuel-use development.
However, for navigation minor differences occur for the emissions of SO2
and NOX due to varying amounts of marine gas oil and residual oil, and for
SO2 and NOX the development in the emission factors also have an impact
on the emission trends. For civil aviation, apart from the annual consumption
of jet fuel, the development of the NOX emissions is also due to yearly
variations in LTO/aircraft type (earlier than 2001) and city-pair statistics
(2001 onwards).
