Not only Germany uses lots of coal, it also uses a lot of the worst kind of coal, lignite. Lignite is low grade coal, Germany has a lot of it, and burning it in local power plants is pretty much the only thing you can do with it, so that's what Germany did.
It also lacks nuclear (because of political decisions), and hydro (presumably because a lack of suitable sites), two of the big low carbon sources.
So Germany may have 50% renewables, but the next one is the worst in terms of emissions (lignite/coal), then there is gas, which is not as bad as coal, but still bad, and that's about it.
And most of the renewables in Germany is solar, which is, according to the website, one of the highest of the low carbon sources. Hydro, wind and nuclear are all lower. Not a big effect though, almost negligible compared to coal.
