Contributed what? Their nuclear exit caused two nuclear power plants to shut down, which were the oldest and smallest in Germany. They had a combined capacity of a just 1 GW - utterly meaningless in the grand scheme of things.
Even when the conservatives pulled the plug on nuclear power plants in 2011, Germany just stopped decreasing emissions of its electricity production for a year or two. And this was at a time of higher gas prices, so it's even up for debate how much the nuclear exit contributed to that short stagnation.
