So, after the first paper about the existing data of CO₂ emissions in Germany, the second paper is about the cause of CO₂ emissions. 

Carbon dioxide emissions in Germany may increase by 4 percent annually in response to a moratorium on seven of the country's oldest nuclear power plants, as power generation is shifted from nuclear power, a zero carbon source, to the other carbon-intensive energy sources that currently make up the country's energy supply.

The country currently relies on nuclear power from its seventeen nuclear power plants for about a quarter of its electricity supply. The moratorium could cause a spike in CO2 emissions as Germany turns to its other, more carbon-intensive sources to supply its energy demand.

Already, the country has been engaged in a "dash for coal", building dozens of new coal plants in response to the perverse incentives and intense lobbying from the coal industries made possible by the European Emissions Trading Scheme.
