Within a sector, the user can define the emissions trajectory of that sector for each nation.
To reach the screen to adjust a National Sector Target, double-click on the Nation from the Sector graph.
To edit the national sector, follow the directions in Changing a Curve. As changes are made, the resulting emissions and ppm contribution are visible in the statistics box.
The National Sector Target is the same as the National Sector Total (since there are no sub-sub-segments to add up). Thus, the National Sector Target is rolled into the Sector Total.
Note, changes in a National Sector Target automatically roll into both the National Total and the Sector Total.
