In 2010, before the shutdowns started, it had 21.5 GW of nuclear.
So if all the other rollouts (renewables, etc) had stayed the same, but the shutdown of nuclear and coal was swapped, Germany could have reduced its emission generation capacity by an extra 66%. (Focusing mainly on coal, since that is (AIUI) the worst of the carbon emitters.)
Germany has 15.4 GW of hard coal generation, and 14.7 GW of lignite, for a total of 30.1 GW:
