The argument here is that a country that keeps talking about green energy, ecology and renewables for decades is now using much less ecological methods of power generation than nuclear, and they keep badmouthing nuclear too.
Germany abandoning nuclear has been decades in the making, it does not come as a surprise. If we look at the whole picture without focusing on one particular energy source, then we can see that they have reduced their CO2 emissions over the years. Not by much, but it's expected to improve when they close down their coal plants.
