Maritime emissions projections
Maritime CO 2 emissions are projected to increase significantly. Depending on future economic and energy
developments, our four BAU scenarios project an increase of between 50% and 250% in the period up to
2050 (see Figure 13). Further action on efficiency and emissions could mitigate emissions growth, although all
but one scenarios project emissions in 2050 to be higher than in 2012, as shown in Figure 14.

Thin lines represent either greater efficiency improvement than BAU or
additional emissions controls or both
