I don’t understand the graph at all. Which line is the purple line? Is it labeled?

It seems like real emissions should end at or before 2020 and none of them do that. They all seem to be projections of some sort?

There is a blueish wider line which is below all the others, shows the effect of the 2008 recession, and splits into multiple forecasts around 2019.
