Germany is not a major country. The 1. Something percent it contributes to the global co2 output just do not matter much.

If you purely think about the climate and don’t care for things like fair resource distribution, forget about the Germans.

Update: Actually if every country with a per capita higher emissions than Germany would drop to German standards we would reduce co2 emissions by 25%.

That sounds like a goal, sind this is even possible without nuclear power, it should be easy for the is and china, who could throw it into the mix.
