Nobody, not even Germans think it is a green country, they aren't pushing that narrative. Who told you that lie?
Most likely you fell victim to American newspapers lying to you that Germany is pushing a green narrative. After all they lied about Germany moving back to coal. What happened is that Germany willingly delayed reductions in CO2 emissions. It clearly cared about the nuclear shutdown more than the coal shutdown. However, the articles are always about how emissions went up "because more coal" when that never happened. It's lies upon lies.
Germany is a country that is standing still, neither getting better nor worse and likes it that way. It's not green and nobody pretended that it is green.
