So I am creating a simple CO2 emissions reduction scenario. The Y axis is in the case the total carbon emissions in GtC. The X axis is the time in years.

Y axis: from 0 to 36.6 (in GtC)

X axis: from 2017 to 2070 (in years)

Lets say the remaining carbon emission budget in this time-frame (53 years) is 1000 GtC.

So if I make a linear reduction from (2017 , 36.6) to (2070 , 0) the cumulative emissions (so the area under the graph) is smaller than 1000 GtC.

Hence, there is still a remaining budget I want to divide over those years. I want to do this without increasing the starting point of the Y-axis.

So for example, a linear graph with a bend in it or a more rounded graph. I want to prevent any extremely steep decreases in any given year though to make it as realistic as possible.

Thanks in advance!

Kind regards,

Tom
