change the sentence into "The measures costs increase when the
selected stabilisation level decreases, but even on a trajectory
towards stabilisation at 450 to 550 ppmv CO2-eq, the impact on

A 9 3 9 4 The description should be modified "but the impact on annual GDP
growth rate is limited." This is too subjective. Recommend to add

excluded.
The definition should be
adjusted to the practice. ( back
to ch.2). probably better to
speak about financial nonclimate
benefits.
Revise footnote.
