To illustrate this, here is a graph from the paper. It shows the number of years of growth you can compensate through saving of emissions by any means except reducing the growth.
If your savings are <10%, you can compensate a few months. If it's around 50%, you can compensate a few years of growth. To compensate order of 10 years of growth you need to reduce emissions by more than 80%.
