The differences in emissions between navigation and civil aviation are<br />

much larger than the differences in fuel consumption (and derived CO2<br />

emissions), and display a poor emission performance for international<br />

sea transport. In broad terms, the emission trends shown in Figure 3.82<br />

are similar <strong>to</strong> the fuel-use development.<br />

However, for navigation minor differences occur for the emissions of<br />

SO2, NOX and CO2 due <strong>to</strong> varying amounts of marine gas oil and residual<br />

oil, and for SO2 and NOX the development in the emission fac<strong>to</strong>rs<br />

also have an impact on the emission trends. For civil aviation, apart<br />

from the annual consumption of jet fuel, the development of the NOX<br />

emissions is also due <strong>to</strong> yearly variations in LTO/aircraft type (earlier<br />

than 2001) and city-pair statistics (2001 onwards).<br />
